1. What Palexia prolonged-release tablets are and what they are used for

Tapentadol, the active substance in Palexia prolonged-release tablets, is a strong painkiller belonging to the opioid class. Palexia prolonged-release tablets are used for the management of severe chronic pain in adults which can only be adequately treated with opioid painkillers.

2. What you should know before using Palexia prolonged-release tablets

Do not use Palexia prolonged-release tablets:

• if you are allergic to tapentadol or to any of the other ingredients of this medicine (listed in section 6),
• if you have asthma or if your breathing is dangerously slow or shallow (respiratory depression, hypercapnia),
• if you have intestinal paralysis,
• if you have acute poisoning due to alcohol, sleeping medicines, painkillers, or other psychotropic medicines (medicines that affect mood and emotions) (see "Other medicines and Palexia prolonged-release tablets").

Warnings and precautions
Talk to your doctor or pharmacist before taking Palexia prolonged-release tablets:

• if you have shortness of breath or weak breathing,
• if you suffer from increased pressure inside the skull or disturbances of consciousness, up to coma,
• if you have had a head injury or brain tumour,
• if you suffer from liver or kidney disorders (see "How to use Palexia prolonged-release tablets"),
• if you suffer from disorders of the pancreas or biliary tract, including pancreatitis,
• if you are taking medicines called mixed opioid agonist/antagonists (such as pentazocine, nalbuphine) or medicines that are partial agonists at mu-opioid receptors (such as buprenorphine),
• if you are prone to epilepsy or seizures, or if you are taking other medicines known to increase the risk of seizures, as the risk of a seizure may increase.

Palexia prolonged-release tablets may lead to physical and psychological dependence. If you have a tendency to abuse medicines or are drug-dependent, you should take this medicine only for short periods and under strict medical supervision.
Sleep-related breathing disorders
Palexia prolonged-release tablets contain an active substance belonging to the group of opioids.
Opioids may cause sleep-related breathing disorders, such as central sleep apnoea (shallow breathing or breathing pauses during sleep) and sleep-related hypoxemia (low blood oxygen levels).
The risk of central sleep apnoea depends on the dose of opioids. Your doctor may consider reducing the total opioid dosage if central sleep apnoea occurs.
Other medicines and Palexia prolonged-release tablets
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
The risk of side effects increases if you are taking medicines that may cause seizures (fits), such as certain antidepressants or antipsychotics. The risk of having a seizure may increase if you take Palexia together with these medicines. Your doctor will advise you whether you can take Palexia.
The concomitant use of Palexia and sedative medicines such as benzodiazepines or similar medicines (some sleeping medicines or tranquilizers (such as barbiturates), painkillers such as opioids, morphine and codeine (also used in cough preparations), antipsychotics, H1 antihistamines, alcohol) increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and may be life-threatening. Therefore, concomitant use should only be considered if no other therapeutic options are possible. However, if your doctor prescribes Palexia together with sedative medicines, they will also determine a reduction in dose and duration of concomitant treatment.
Inform your doctor about all sedative medicines you are taking and follow their dose recommendations strictly. It may be helpful to inform relatives or friends to watch for the signs and symptoms listed above. Contact your doctor if you experience these symptoms.
If you are taking a type of medicine that affects serotonin levels (such as certain medicines for treating depression), talk to your doctor before taking Palexia, because cases of "serotonin syndrome" have been reported. Serotonin syndrome is rare but potentially life-threatening. Symptoms include uncontrollable rhythmic muscle contractions including muscles controlling eye movements, agitation, excessive sweating, tremors, exaggerated reflexes, increased muscle tension, and body temperature above 38°C. Your doctor can inform you about this.
The use of Palexia prolonged-release tablets together with other types of medicines known as mu-receptor agonists/antagonists (such as pentazocine, nalbuphine) or partial mu-opioid receptor agonists (such as buprenorphine) has not been studied. Palexia prolonged-release tablets may not be effective if taken together with one of these medicines. Inform your doctor if you are taking any of these medicines.
Taking Palexia prolonged-release tablets together with certain medicines (such as rifampicin, phenobarbital, St. John's wort), strong inhibitors or inducers of enzymes involved in tapentadol elimination, may affect the efficacy of tapentadol and may cause side effects, especially at the beginning or end of treatment with these medicines. Keep your doctor informed about all medicines you are taking.
Palexia prolonged-release tablets must not be taken together with MAO inhibitors (a type of medicine used to treat depression). Inform your doctor if you are taking MAO inhibitors or have taken them within the last 14 days.
Palexia prolonged-release tablets with food, drinks and alcohol
Do not drink alcohol during treatment with Palexia prolonged-release tablets, as some side effects such as drowsiness may increase. Food does not affect the efficacy of this medicine.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, if you suspect you may be pregnant or are planning to become pregnant, ask your doctor or pharmacist for advice before using this medicine.
Do not take these tablets:

• if you are pregnant, unless your doctor has specifically instructed you to do so. Prolonged use of tapentadol during pregnancy may cause withdrawal symptoms in the newborn, which can be life-threatening if not recognized and treated by a doctor.
• during childbirth, because the newborn's breathing may slow down or become dangerously weak (respiratory failure),
• while breastfeeding, because the medicine may be excreted in breast milk.

Driving and using machines
Palexia prolonged-release tablets may cause drowsiness, dizziness, and blurred vision, and may reduce reaction time. This may especially occur when starting treatment with Palexia prolonged-release tablets, when your doctor changes your dose, or when you drink alcohol or take tranquilizers.
Ask your doctor whether you can drive or operate machinery.
Palexia prolonged-release tablets contain lactose
If your doctor has diagnosed you with an intolerance to certain sugars, contact them before taking this medicine.

3. How to use Palexia prolonged-release tablets

Take this medicine exactly as directed by your doctor or pharmacist. If you have any doubts, consult your doctor or pharmacist.
Your doctor will determine the dosage based on the intensity of your pain and your individual sensitivity to pain. In general, the lowest effective dose that relieves pain should be used.
Adults
The usual dose is 1 tablet every 12 hours. Total daily doses of Palexia prolonged-release tablets exceeding 500 mg of tapentadol are not recommended. Your doctor may prescribe a different or more appropriate dose or dosing interval if necessary. If you feel that the effect of these tablets is too strong or too weak, consult your doctor or pharmacist.
Elderly patients
In elderly patients (over 65 years of age), dose adjustment is generally not required. However, excretion of tapentadol may be slowed in some patients in this group. If this applies to you, your doctor may prescribe a different dosage.
Hepatic and renal impairment (insufficiency)
Patients with severe liver problems must not take these tablets. If you have mild liver problems, your doctor will prescribe a different dosage. In patients with mild liver impairment, no dose adjustment is necessary.
Patients with severe kidney problems must not take these tablets. In patients with mild or moderate renal impairment, no dose adjustment is necessary.
Use in children and adolescents
Palexia prolonged-release tablets are not suitable for children and adolescents under 18 years of age.
How and when to take Palexia prolonged-release tablets
Palexia prolonged-release tablets are for oral use.
Always swallow the tablets whole with sufficient liquid.
Do not chew, break, or crush the tablets, as this could lead to overdose due to rapid release of the drug into the body.
You may take the tablets on an empty stomach or with food.
The empty tablet shell may not be completely digested and may therefore be found in the stool. This is not a cause for concern, as the active substance of the tablet has already been absorbed by your body, and what you see is only the empty shell.
Duration of treatment
Do not take the tablets for longer than prescribed by your doctor.
If you take more Palexia prolonged-release tablets than you should
After taking very high doses, the following may occur:

• pinpoint pupils, vomiting, low blood pressure, rapid heartbeat, collapse, disturbances of consciousness or coma (deep unconsciousness), seizures, dangerously slow and shallow breathing, or respiratory arrest. In such cases, contact your doctor immediately.

If you forget to take Palexia prolonged-release tablets
If you miss a dose, your pain may return. Do not take a double dose to make up for the missed tablet; simply continue taking the tablets as before.
If you stop taking Palexia prolonged-release tablets
If you stop or discontinue treatment too early, your pain may return. If you wish to stop treatment, consult your doctor.
Generally, withdrawal effects do not occur when stopping treatment. However, in rare cases, individuals who have taken the tablets for a prolonged period may feel unwell if treatment is stopped abruptly.
Symptoms may include:

• nervousness, tearing, runny nose, yawning, sweating, chills, muscle pain, and dilated pupils,
• irritability, anxiety, back pain, joint pain, weakness, abdominal cramps, difficulty sleeping, nausea, loss of appetite, vomiting, diarrhea, and increased blood pressure, breathing rate, or heart rate. If you experience any of these symptoms after stopping treatment, consult your doctor. Do not stop taking this medicine abruptly unless otherwise instructed by your doctor. If your doctor advises you to stop taking the tablets, they will guide you on how to do so, which may include gradually reducing the dose.

If you have any questions about the use of this medicine, consult your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everyone experiences them.
Important side effects or symptoms to pay attention to, and what to do if they occur:
this medicine may cause allergic reactions. Symptoms may include shortness of breath, wheezing, swelling of the eyelids, face or lips, skin rash or itching, especially affecting the whole body. Another serious side effect is worsening of breathing or more pronounced shortness of breath than expected. This occurs mainly in elderly or frail patients.
In such cases, contact your doctor immediately.
Other possible side effects are:
Very common (may affect more than 1 in 10 people): nausea, constipation, dizziness, drowsiness, headache.
Common (may affect up to 1 in 10 people): loss of appetite, anxiety, depressed mood, sleep disturbances, nervousness, restlessness, attention disturbances, tremor, muscle twitching, flushing, shortness of breath, vomiting, diarrhoea, indigestion, itching, increased sweating, skin rash, feeling of weakness, fatigue, sensation of body temperature fluctuations, dryness of mucous membranes, fluid accumulation in tissues (oedema).
Uncommon (may affect up to 1 in 100 people): allergic reactions to the medicine (including subcutaneous oedema, urticaria, and in severe cases, breathing difficulties, drop in blood pressure, collapse or shock), weight loss, disorientation, confusion, excitability (agitation), disturbances in perception, unusual dreams, euphoria, reduced level of consciousness, memory impairment, mental impairment, fainting, sedation, balance disorders, difficulty speaking, numbness, abnormal skin sensations (e.g. tingling, pricking), blurred vision, increased heart rate, slowed heart rate, palpitations, low blood pressure, abdominal discomfort, urticaria, difficulty urinating, increased frequency of urination, sexual dysfunction, withdrawal syndrome (see "When stopping treatment with Palexia"), feeling strange, irritability.
Rare (may affect up to 1 in 1,000 people): drug dependence, abnormal thoughts, epileptic seizures, feeling faint, abnormal coordination, dangerous slowing of breathing or shortness of breath (respiratory depression), problems with gastric emptying, feeling drunk, sensation of relaxation.
Frequency not known: delirium.
Generally, the likelihood of having suicidal thoughts or behaviour increases in patients suffering from chronic pain. In addition, some medicines used to treat depression (which therefore affect the brain's neurotransmission system) may increase this risk, especially at the beginning of treatment.
Although tapentadol also acts on neurotransmitters, clinical use data do not show an increased risk.
Reporting of side effects
If you experience any side effect, including those not listed in this leaflet, talk to your doctor or pharmacist. You may also report side effects directly via the national reporting system at https://www.aifa.gov.it/content/segnalazioni-reazioni-avverse .

1. What Palexia is and what it is used for

Tapentadol, the active substance in Palexia, is a strong analgesic belonging to the opioid class.
Palexia is used for the treatment of moderate to severe acute pain in adults which can be adequately managed only with opioid analgesics.

2. What you should know before using Palexia

Do not use P alexia

• If you are allergic to tapentadol or to any of the other ingredients of this medicine (listed in section 6)
• if you have asthma or if your breathing is dangerously slow or shallow (respiratory depression, hypercapnia)
• if you have intestinal paralysis
• if you have acute alcohol, sedative, opioid or other psychotropic drug poisoning (medicines acting on mood and emotions) (see "Other medicines and Palexia")

Warnings and precautions
Talk to your doctor or pharmacist before taking Palexia:

• if you have shortness of breath or weak breathing,
• if you suffer from increased pressure inside the skull or disturbances of consciousness, up to coma,
• if you have had a head injury or brain tumour,
• if you suffer from liver or kidney disorders (see "How to use Palexia")
• if you suffer from pancreatic or biliary tract disorders, including pancreatitis,
• if you are taking medicines called opioid agonist/antagonists (such as pentazocine, nalbuphine) or partially mu-opioid receptor agonist medicines (such as buprenorphine)
• if you are prone to epilepsy or seizures, or if you are taking other medicines known to increase the risk of seizures, as the risk of a seizure may increase.

Palexia may lead to physical and psychological dependence. If you have a tendency to drug abuse or are drug-dependent, you should take this medicine only for short periods and under strict medical supervision.
Sleep-related breathing disorders
Palexia contains an active substance belonging to the group of opioids. Opioids may cause sleep-related breathing disorders, such as central sleep apnoea (shallow breathing or breathing pauses during sleep) and sleep-related hypoxaemia (low blood oxygen levels).
The risk of central sleep apnoea occurring depends on the dose of opioids. Your doctor may consider reducing the total opioid dosage if central sleep apnoea occurs.
Other medicines and Palexia
Inform your doctor or pharmacist if you are taking, or have recently taken, any other medicines.
The risk of adverse effects increases if you are taking medicines that may cause seizures (fits), such as certain antidepressants or antipsychotics. The risk of having a seizure may increase if you take Palexia together with these medicines. Your doctor will advise you whether you can take Palexia.
Concomitant use of Palexia and sedative medicines such as benzodiazepines or similar medicines (some sleeping medicines or tranquilizers (such as barbiturates), painkillers such as opioids, morphine and codeine (also used in cough suppressants), antipsychotics, H1 antihistamines, alcohol) increases the risk of drowsiness, difficulty breathing (respiratory depression), coma and may be life-threatening. For this reason, concomitant use should only be considered if no other therapeutic options are available. However, if your doctor prescribes Palexia together with sedative medicines, he/she will also determine a reduction in dose and duration of concomitant treatment.
Inform your doctor about all sedative medicines you are taking and follow his/her dose recommendations carefully. It may be helpful to inform relatives or friends to pay attention to the signs and symptoms listed above. Contact your doctor if you experience these symptoms.
If you are taking a type of medicine that affects serotonin levels (such as certain medicines for the treatment of depression), discuss this with your doctor before taking Palexia, as cases of "serotonin syndrome" have been reported. Serotonin syndrome is rare but potentially life-threatening. Symptoms include uncontrollable rhythmic muscle contractions including muscles controlling eye movements, agitation, excessive sweating, tremor, exaggerated reflexes, increased muscle tone and body temperature above 38°C. Your doctor can provide you with further information.
The use of Palexia together with other medicines known as μ-receptor agonist/antagonists (such as pentazocine, nalbuphine) or partial μ-opioid receptor agonists (such as buprenorphine) has not been studied. Palexia may be less effective if taken together with any of these medicines. Inform your doctor if you are taking any of these medicines.
Taking Palexia together with certain medicines (such as rifampicin, phenobarbital, St. John's wort), strong inhibitors or inducers of certain enzymes required to eliminate tapentadol from the body, may affect the efficacy of tapentadol and may cause adverse effects, especially at the beginning or end of treatment with these medicines. Keep your doctor informed about all medicines you are taking.
Palexia must not be taken together with MAO inhibitors (a type of medicine used to treat depression). Inform your doctor if you are taking MAO inhibitors or have taken them within the last 14 days.
Palexia with food, drinks and alcohol
Do not drink alcohol during treatment with Palexia, as certain side effects such as drowsiness may increase. Food does not affect the efficacy of this medicine.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, if you suspect you may be pregnant or are planning to become pregnant, ask your doctor or pharmacist for advice before using this medicine.
Do not take these tablets:

• if you are pregnant, unless your doctor has specifically instructed you to do so; prolonged use of tapentadol during pregnancy may cause withdrawal symptoms in the newborn, which may be life-threatening if not recognized and treated by a doctor.
• during childbirth, because the newborn's breathing may dangerously slow down or weaken (respiratory failure),
• during breastfeeding, because the medicine may be excreted in breast milk.

Driving and using machines:
Palexia may cause drowsiness, dizziness and blurred vision and may reduce reaction time. This may especially occur when starting treatment with Palexia, when your doctor changes your dose, or when you drink alcohol or take tranquilizers. Ask your doctor whether you may drive a vehicle or operate machinery.
Palexia contains lactose
If your doctor has diagnosed you with an intolerance to certain sugars, contact him/her before taking this medicine.

3. How to use Palexia

Take this medicine exactly as directed by your doctor or pharmacist. If you have any doubts, consult your doctor or pharmacist.

Your doctor will determine the dosage based on the intensity of your pain and your individual sensitivity to pain. In general, the lowest effective dose that relieves pain should be used.

Adults
The usual dose is 1 tablet every 4–6 hours. Total daily doses of Palexia exceeding 700 mg of tapentadol on the first day of treatment and exceeding 600 mg of tapentadol on subsequent days are not recommended. Your doctor may prescribe a different or more appropriate dosage or dosing interval if necessary. If you feel that the effect of these tablets is too strong or too weak, consult your doctor or pharmacist.

Elderly patients
In elderly patients (over 65 years of age), dosage adjustment is generally not required. However, elimination of tapentadolo may be slowed in some individuals in this group. If this applies to you, your doctor may prescribe a different dosage.

Hepatic and renal disorders (insufficiency)
Patients with severe liver problems must not take these tablets. If you have mild liver impairment, dosage adjustment is not necessary. For moderate liver impairment, your doctor will prescribe a different dosage.

Patients with severe kidney problems must not take these tablets. For mild to moderate renal impairment, dosage adjustment is not necessary.

Use in children and adolescents
Palexia is not suitable for children and adolescents under 18 years of age.

How and when to take Palexia
Palexia is for oral use.
Always swallow the tablets with sufficient liquid.
You may take the tablets on an empty stomach or with food.

Duration of treatment
Do not take the tablets for longer than prescribed by your doctor.

If you take more Palexia than you should
After taking very high doses, the following may occur:

• Pinpoint pupils, vomiting, low blood pressure, rapid heartbeat, circulatory collapse, disturbances of consciousness or coma (deep unconsciousness), epileptic seizures, dangerously slow and shallow breathing, or respiratory arrest. In such cases, seek immediate medical help.

If you forget to take Palexia
If you forget to take a dose, your pain may return. Do not take a double dose to make up for the missed tablet; simply continue taking the tablets as before.

If you stop taking Palexia
If you stop or discontinue treatment too early, your pain may return. If you wish to stop treatment due to side effects, consult your doctor.
Generally, withdrawal effects do not occur when stopping treatment. However, in rare cases, individuals who have taken the tablets for a prolonged period may feel unwell if treatment is stopped abruptly.
Symptoms may include:

• Restlessness, tearing, runny nose, yawning, chills, muscle pain, and dilated pupils,
• Irritability, anxiety, back pain, joint pain, weakness, abdominal cramps, difficulty sleeping, nausea, loss of appetite, vomiting, diarrhea, and increased blood pressure, breathing rate, or heart rate.

If you experience any of these symptoms after stopping treatment, consult your doctor. You should not stop taking this medicine abruptly unless your doctor advises otherwise. If your doctor decides that you should stop taking the tablets, they will instruct you on how to do so, which may include gradually reducing the dose.

If you have any questions about the use of this medicine, consult your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Serious side effects or symptoms to pay attention to and what to do if they occur:
this medicine may cause allergic reactions. Symptoms may include shortness of breath, wheezing, swelling of the eyelids, face or lips, skin rash or itching, especially affecting the entire body. Another serious side effect is slowed breathing or more pronounced shortness of breath than expected. This mainly occurs in elderly or weakened patients.
In such cases, contact your doctor immediately.
Other possible side effects are:
Very common (may affect more than 1 in 10 people): nausea, vomiting, dizziness, drowsiness, headache
Common (may affect up to 1 in 10 people): decreased appetite, anxiety, confusion, hallucinations, sleep disturbances, unusual dreams, tremors, hot flushes, constipation, diarrhoea, indigestion, dry mouth, itching, increased sweating, rash, muscle cramps, feeling of weakness, fatigue, sensation of temperature fluctuations.
Uncommon (may affect up to 1 in 100 people): depression, disorientation, excitability (agitation), nervousness, restlessness, euphoria, attention disturbances, memory impairment, feeling faint, sedation, difficulty controlling movements, difficulty speaking, numbness, abnormal skin sensations (e.g. tingling, pricking), involuntary muscle contractions, distorted vision, increased heart rate, palpitations, low blood pressure, dangerous slowing of breathing or shortness of breath (respiratory depression), reduced oxygen levels in the blood, slowed breathing, abdominal discomfort, urticaria, feeling of heaviness, difficulty urinating, increased frequency of urination, withdrawal syndrome (see "If you stop taking Palexia"), fluid accumulation in tissues (oedema), strange sensations, feeling drunk, irritability, sensation of relaxation.
Rare (may affect up to 1 in 1,000 people): allergic reactions to the medicine, including swelling under the skin, and urticaria, and in severe cases, difficulty breathing, drop in blood pressure, collapse or shock), unusual thoughts, epileptic seizures, reduced level of consciousness, abnormal coordination, slowed heart rate, problems with gastric emptying.
Frequency not known: delirium
Generally, the likelihood of having suicidal thoughts or behaviour increases in patients suffering from chronic pain. In addition, some medicines used to treat depression (which therefore affect the brain's neurotransmission system) may increase this risk, especially at the beginning of treatment.
Although tapentadol acts on neurotransmission, clinical use data for tapentadol do not show an increased risk.
Reporting of side effects
If you experience any side effect, including those not listed in this leaflet, talk to your doctor or pharmacist. You can also report side effects directly via the national reporting system at https://www.aifa.gov.it/content/segnalazioni-reazioni-avverse. By reporting side effects, you can help provide more information on the safety of this medicine.

1. What PALEXIA is and what it is used for

Tapentadol, the active substance in Palexia, is a strong painkiller belonging to the opioid class.
Palexia is used to treat moderate to severe acute pain in children and adolescents from 2 years of age and in adults, when the pain can only be adequately managed with opioid painkillers.

2. What you should know before taking PALEXIA

Do not take P alexia

• If you are allergic to tapentadol or to any of the other ingredients of this medicine (see section 6)
• if you have asthma or if your breathing is dangerously slow or shallow (respiratory depression, hypercapnia)
• if you have intestinal paralysis
• if you have acute poisoning due to alcohol, sleeping medicines, painkillers, or other psychotropic medicines (medicines that affect mood and emotions) (see "Other medicines and Palexia")

Warnings and precautions
Talk to your doctor or pharmacist before taking Palexia if:

• you have short or weak breathing
• you suffer from increased pressure in the brain or disturbances of consciousness, up to coma
• you have had head injuries or a brain tumor
• you suffer from liver or kidney problems (see "How to take Palexia")
• you suffer from pancreatic or biliary tract disorders, including pancreatitis
• you are taking medicines called opioid agonist/antagonists (such as pentazocine, nalbuphine) or partial mu-opioid receptor agonists (such as buprenorphine)
• you are prone to epilepsy or seizures, or if you are taking other medicines known to increase the risk of seizures, as the risk of a seizure may increase
• you or a family member has ever abused or been dependent on alcohol, prescription medicines, or illegal substances (“addiction”)
• you are a smoker
• you have had mood disorders (depression, anxiety, or a personality disorder) or have been treated by a psychiatrist for other mental illnesses

This medicine contains tapentadol, which is an opioid medicine. Repeated use of opioid painkillers may lead to reduced effectiveness of the medicine (you may become accustomed to it). It may also cause dependence and abuse, which can lead to potentially life-threatening overdose. Ask your doctor for advice if you are concerned about becoming addicted to Palexia. Use (even at therapeutic doses) may lead to physical dependence, resulting in withdrawal symptoms and a recurrence of problems if treatment with this medicine is stopped suddenly.
Palexia may lead to physical and psychological dependence. If you have a tendency to abuse medicines or are dependent on medicines, you should take this medicine only for short periods and under strict medical supervision.
Obese children should be closely monitored and the maximum recommended dose must not be exceeded.
Do not give this medicine to children under 2 years of age.

Sleep-related breathing disorders
Palexia may cause sleep-related breathing disorders, such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low levels of oxygen in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to breathlessness, difficulty maintaining sleep, or excessive daytime sleepiness. If you or someone else notices these symptoms, consult your doctor. Your doctor may consider reducing the dose.

Other medicines and Palexia
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

• The risk of side effects increases if you are taking medicines that can cause seizures (fits), such as certain antidepressants or antipsychotics. The risk of having a seizure may increase if you take Palexia together with these medicines. Your doctor will tell you whether you can take Palexia.
• The concomitant use of Palexia and sedative medicines such as benzodiazepines or similar medicines (some sleeping medicines or tranquilizers (such as barbiturates), painkillers such as opioids, morphine and codeine (also used in cough preparations), antipsychotics, H1 antihistamines, alcohol) increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and may be life-threatening. For this reason, concomitant use should only be considered if no other therapeutic options are available. However, if your doctor prescribes Palexia together with sedative medicines, they will also determine a reduction in dose and duration of concomitant treatment.

The simultaneous use of opioids and medicines used to treat epilepsy, nerve pain, or anxiety (gabapentin and pregabalin) increases the risk of opioid overdose, respiratory depression, and may be potentially life-threatening.
Inform your doctor if you are taking gabapentin or pregabalin or other sedative medicines and follow their dose recommendations carefully. It may be helpful to inform relatives or friends to pay attention to the signs and symptoms listed above. Contact your doctor if you experience these symptoms.

• If you are taking a type of medicine that affects serotonin levels (such as certain medicines for treating depression), discuss this with your doctor before taking Palexia, as cases of "serotonin syndrome" have been reported. Serotonin syndrome is rare but potentially life-threatening. Symptoms include rhythmic, uncontrollable muscle contractions including those controlling eye movements, agitation, excessive sweating, tremors, exaggerated reflexes, increased muscle tone, and body temperature above 38°C. Your doctor can provide further information on this.
• The use of Palexia together with other medicines known as mixed mu-receptor agonist/antagonists (such as pentazocine and nalbuphine) or partial mu-opioid receptor agonists (such as buprenorphine) has not been studied. Palexia may not be effective if taken together with any of these medicines. Inform your doctor if you are taking any of these medicines.
• Taking Palexia together with certain medicines (such as rifampicin, phenobarbital, St. John's wort), strong inhibitors or inducers of enzymes involved in tapentadol elimination, may affect the effectiveness of tapentadol or cause side effects, especially at the beginning or end of treatment with these medicines. Keep your doctor informed about all medicines you are taking.
• Palexia must not be taken together with MAO inhibitors (a type of medicine used to treat depression). Inform your doctor if you are taking MAO inhibitors or have taken them within the last 14 days.

Palexia with food, drinks, and alcohol
Do not drink alcohol during treatment with Palexia, as some side effects such as drowsiness may increase. Food does not affect the effectiveness of this medicine.

Pregnancy and breastfeeding
If you are pregnant, think you may be pregnant, planning to become pregnant, or breastfeeding, consult your doctor or pharmacist before taking this medicine.

Do not take this medicine:

• if you are pregnant, unless your doctor has specifically instructed you to do so. Prolonged use of tapentadol during pregnancy may cause withdrawal symptoms in the newborn, which can be life-threatening if not recognized and treated by a doctor.

The use of Palexia is not recommended:

• during childbirth, because the newborn's breathing may dangerously slow down or weaken (respiratory failure)
• during breastfeeding, because tapentadol may be excreted in breast milk.

Driving and using machines
Palexia may cause drowsiness, dizziness, and blurred vision, and may impair reaction time. This may especially occur when starting treatment with Palexia, when your doctor changes your dose, or if you drink alcohol or take tranquilizers. Ask your doctor whether you can drive or operate machinery.

Palexia 4 mg/ml contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per maximum single dose, i.e. essentially "sodium-free".

Palexia 4 mg/ml contains sodium benzoate
This medicine contains 59 mg of sodium benzoate per unit of volume, equivalent to 2.4 mg/ml. Sodium benzoate may increase jaundice (yellowing of the skin and eyes) in newborns (up to 4 weeks of age).

Palexia 4 mg/ml contains propylene glycol

3. How to take PALEXIA

Take this medicine exactly as directed by your doctor or pharmacist. If you
have any doubts, consult your doctor or pharmacist.
Your doctor will decide the dosage based on the intensity of your pain and your individual sensitivity to pain.
In general, the lowest effective dose that relieves pain should be used.
Adults
The usual dose is 50 mg of tapentadol (12.5 ml of oral solution), 75 mg of tapentadol (18.75 ml of oral
solution), or 100 mg of tapentadol (25 ml of oral solution) every 4–6 hours.
Total daily doses exceeding 700 mg of tapentadol on the first day of treatment and exceeding 600 mg of
tapentadol on subsequent days are not recommended.
Your doctor may prescribe a different dosage or dosing interval if necessary. If you feel that the effect of this
medicine is too strong or too weak, consult your doctor or pharmacist.
Elderly patients
In elderly patients (over 65 years of age), dosage adjustment is generally not required. However, excretion of
tapentadol may be slowed in some individuals in this age group. If this applies to you, your doctor may
prescribe a different dosage.
Hepatic and renal impairment (insufficiency)
Patients with severe liver problems must not take this medicine. If you have mild liver problems, your doctor
will prescribe an adjusted dosage. No dosage adjustment is necessary in cases of mild liver impairment.
Patients with severe kidney problems must not take this medicine. No dosage adjustment is necessary in cases
of mild or moderate renal impairment.
Use in children and adolescents
Palexia should be administered to children only in a hospital setting.
The dosage of Palexia in children and adolescents from 2 years up to but less than 18 years of age is 1.25 mg/kg

Always wait 4 hours before administering the next dose. The dose may be reduced as acute pain decreases.
The correct dosage will be determined by the doctor.
Hepatic and renal impairment (insufficiency)
Children and adolescents with liver or kidney problems must not take this medicine.
How and when to take Palexia
Palexia is for oral use.
You may take the oral solution on an empty stomach or with food.
The package contains a dosing syringe with an attached adapter, which must be used to withdraw the exact
amount (volume) corresponding to the prescribed dose of tapentadol from the bottle.
Instructions for opening the bottle and using the dosing syringe

The bottle has a child-resistant cap. To remove the cap, press down firmly and turn
counterclockwise. (Fig.1). Remove the cap and discard the seal from the bottle neck. If the seal is
damaged, do not use the medicine and contact your pharmacist.
Place the bottle on a stable, flat surface. Open the plastic pouch containing the

dosing syringe/adapter along the perforated line and remove the dosing syringe (A) with the
adapter inserted (B). Firmly insert the dosing syringe, with the adapter end first, into the neck of
the bottle (Fig.2).

To fill the dosing syringe, turn the bottle upside down. While holding the dosing syringe steady,
pull the plunger (C) downward until it reaches the mark corresponding to the dose prescribed by
your doctor (see section “How to use Palexia”). Do not remove the dosing syringe at this
time! (Fig.3)

Turn the bottle upright again, then carefully remove the dosing syringe from the bottle. After
removal, carefully check that you have drawn up the correct dose of solution. The adapter (B),
which was previously attached to the dosing syringe, will remain on the bottle (Fig.4).
Take the medicine by placing the dosing syringe in your mouth and pushing the plunger. Push the

plunger fully to ensure that all the solution is used. If preferred, you may dilute the medicine in
a glass of water or non-alcoholic drink before taking it; in this case, drink the entire glass to
ensure that you receive the full dose of medicine. (Fig.5).
Leave the adapter on the bottle, close the cap tightly, and store the bottle in an upright position. Rinse the
dosing syringe with water after use and allow it to dry thoroughly. When taking the medicine next time, insert
the dosing syringe into the adapter on the bottle neck and follow the instructions above.
How long to take Palexia
Do not take this medicine longer than prescribed by your doctor.
If you take more Palexia than you should:
After taking very high doses, the following may occur:

• pinpoint pupils, vomiting, low blood pressure, rapid heartbeat, collapse, disturbances of consciousness or coma (deep unconsciousness), seizures, dangerously slow and shallow breathing, or respiratory arrest.

In such cases, contact your doctor immediately.
If you forget to take Palexia
If you forget to take this medicine, your pain may return. Do not take a double dose to make up for the
missed dose; simply continue taking the medicine as before.
If you stop taking Palexia
If you stop or end treatment too early, your pain may return. If you wish to stop treatment, consult your doctor
first.
Generally, no withdrawal effects occur when treatment is stopped. However, in rare cases, individuals who
have taken the medicine for a prolonged period may feel unwell if treatment is stopped abruptly.
Symptoms may include:

• restlessness, tearing, runny nose, yawning, sweating, chills, muscle aches, and dilated pupils
• irritability, anxiety, backache, joint pain, weakness, abdominal cramps, difficulty sleeping, nausea, loss of appetite, vomiting, diarrhea, and increased blood pressure, breathing rate, or heart rate. If you experience any of these symptoms after stopping treatment, consult your doctor. You must not stop taking this medicine abruptly unless your doctor tells you otherwise. If your doctor advises stopping this medicine, they will instruct you how to do so, which may include gradually reducing the dose.

If you have any questions about the use of this medicine, consult your doctor or pharmacist.

Rare (may affect up to 1 in 1,000 people): allergic reactions to the medicine (including swelling under the skin, urticaria, and in severe cases, difficulty breathing, drop in blood pressure, collapse or shock), strange thoughts, epileptic seizures, reduced level of consciousness, abnormal coordination, slower heartbeat, problems with gastric emptying

Frequency not known: delirium

Generally, the risk of having suicidal thoughts or behaviour increases in patients suffering from chronic pain. In addition, some medicines used to treat depression (which therefore affect the brain's neurotransmission system) may increase this risk, especially at the beginning of treatment. Although tapentadol also acts on neurotransmission, clinical use data for tapentadol do not show an increased risk.

No additional side effects have been observed in children and adolescents

Tapentadol
Please read this leaflet carefully before taking this medicine because it contains important information for you.

• Keep this leaflet; you may need to read it again.
• If you have any questions, consult your doctor or pharmacist.
• This medicine has been prescribed for you. Do not give it to others, even if their symptoms are the same as yours, as it could be harmful.

1. What PALEXIA is and what it is used for

Tapentadol, the active substance in Palexia, is a strong analgesic belonging to the opioid class.
Palexia is used for the treatment of moderate to severe acute pain in children and adolescents from 2 years of age with body weight above 16 kg, and in adults who can only be adequately managed with opioid analgesics.

2. What you should know before taking PALEXIA

Do not take P alexia

• If you are allergic to tapentadol or to any of the other ingredients of this medicine (see section 6)
• if you have asthma or if your breathing is dangerously slow or shallow (respiratory depression, hypercapnia)
• if you have intestinal paralysis
• if you have acute poisoning due to alcohol, sleeping medicines, painkillers or other psychotropic medicines (medicines acting on mood and emotions) (see “Other medicines and Palexia”)

Warnings and precautions
Talk to your doctor or pharmacist before taking Palexia if:

• you have shortness of breath or weak breathing
• you suffer from increased pressure in the brain or disturbances of consciousness, up to coma
• you have had head injuries or a brain tumor
• you suffer from liver or kidney problems (see “How to take Palexia”)
• you suffer from pancreatic or biliary tract disorders, including pancreatitis
• you are taking medicines called opioid agonist/antagonists (such as pentazocine, nalbuphine) or partial mu-opioid receptor agonists (such as buprenorphine)
• you are prone to epilepsy or seizures, or if you are taking other medicines known to increase the risk of seizures, as the risk of seizure may increase
• you or a family member has ever abused or been dependent on alcohol, prescription medicines or illegal substances (“addiction”)
• you are a smoker
• you have had mood disorders (depression, anxiety or a personality disorder) or have been treated by a psychiatrist for other mental illnesses

This medicine contains tapentadol, which is an opioid medicine. Repeated use of opioid painkillers may lead to reduced effectiveness of the drug (you may become tolerant to it). It may also cause dependence and abuse, which can lead to potentially life-threatening overdose. Ask your doctor for advice if you are concerned about developing dependence on Palexia. Use (even at therapeutic doses) may lead to physical dependence, resulting in withdrawal symptoms and recurrence of problems if treatment with this medicine is stopped suddenly.
Palexia may lead to physical and psychological dependence. If you have a tendency to abuse medicines or are dependent on medicines, you should take this medicine only for short periods and under strict medical supervision.
Obese children must be closely monitored and the maximum recommended dose must not be exceeded.
Do not give this medicine to children under 2 years of age or with a body weight below 16 kg.

Sleep-related breathing disorders
Palexia may cause sleep-related breathing disorders, such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low levels of oxygen in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to breathlessness, difficulty maintaining sleep, or excessive daytime sleepiness. If you or someone else observes these symptoms, consult your doctor. Your doctor may consider reducing the dose.

Other medicines and Palexia
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicine.

• The risk of adverse effects increases if you are taking medicines that can cause seizures (fits), such as certain antidepressants or antipsychotics. The risk of having a seizure may increase if you take Palexia together with these medicines. Your doctor will tell you whether you can take Palexia.
• The concomitant use of Palexia and sedative medicines such as benzodiazepines or similar medicines (some sleeping or tranquilizing medicines (such as barbiturates), painkillers such as opioids, morphine and codeine (also used in cough preparations), antipsychotics, H1 antihistamines, alcohol) increases the risk of drowsiness, difficulty breathing (respiratory depression), coma and may be life-threatening. For this reason, concomitant use should only be considered if no other therapeutic options are available. However, if your doctor prescribes Palexia together with sedative medicines, they will also establish a reduction in dose and duration of concomitant treatment.

The simultaneous use of opioids and medicines for the treatment of epilepsy, nerve pain or anxiety
(gabapentin and pregabalin) increases the risk of opioid overdose, respiratory depression and
may be potentially life-threatening.

• Inform your doctor if you are taking gabapentin or pregabalin or other sedative medicines and follow their dose recommendations carefully. It may be helpful to inform relatives or friends to pay attention to the signs and symptoms listed above. Contact your doctor if you experience these symptoms. If you are taking a type of medicine that affects serotonin levels (such as certain medicines for the treatment of depression), talk to your doctor before taking Palexia because cases of “serotonin syndrome” have been reported.

Serotonin syndrome is rare but a potentially life-threatening condition. Symptoms include uncontrollable rhythmic muscle contractions including muscles controlling eye movements, agitation, excessive sweating, tremors, exaggerated reflexes, increased muscle tone and body temperature above 38°C. Your doctor can advise you about this.

• The use of Palexia together with other medicines known as mixed mu-receptor agonist/antagonists (such as pentazocine and nalbuphine) or partial mu-opioid receptor agonists (such as buprenorphine) has not been studied. Palexia may not be effective if taken together with any of these medicines. Inform your doctor if you are taking any of these medicines.
• Taking Palexia together with certain medicines (such as rifampicin, phenobarbital, St. John’s wort), strong inhibitors or inducers of enzymes needed to eliminate tapentadol from the body, may affect the effectiveness of tapentadol or may cause adverse effects, especially at the beginning or end of treatment with these medicines. Keep your doctor informed about all medicines you are taking.
• Palexia must not be taken together with MAO inhibitors (a type of medicine used to treat depression). Inform your doctor if you are taking MAO inhibitors or have taken them within the last 14 days.

Palexia with food, drinks and alcohol
Do not drink alcohol during treatment with Palexia, as some adverse effects such as drowsiness may increase. Food does not affect the effectiveness of this medicine.

Pregnancy and breastfeeding
If you are pregnant, think you may be pregnant, are planning to become pregnant, or are breastfeeding, ask your doctor or pharmacist for advice before taking this medicine.

Do not take this medicine:

• if you are pregnant, unless your doctor has specifically instructed you to do so. If used for prolonged periods during pregnancy, tapentadol may cause withdrawal symptoms in the newborn, which may be life-threatening if not recognized and treated by a doctor.

The use of Palexia is not recommended:

• during childbirth, because the newborn’s breathing may slow down or become dangerously weak (respiratory failure)
• during breastfeeding, because tapentadol may be excreted in breast milk.

Driving and using machines
Palexia may cause drowsiness, dizziness and blurred vision and may impair reaction time. This may especially occur when starting Palexia treatment, when your doctor changes your dose, or if you drink alcohol or take tranquilizers. Ask your doctor whether you can drive or operate machinery.

Palexia 20 mg/ml contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per maximum single dose, i.e. essentially "sodium-free".

Palexia 20 mg/ml contains sodium benzoate
This medicine contains 5.9 mg of sodium benzoate in 5 ml of solution (maximum single dose), equivalent to 1.18 mg/ml.
Sodium benzoate may increase jaundice (yellowing of the skin and eyes) in newborns (up to 4 weeks of age).

Palexia 20 mg/ml contains propylene glycol
This medicine contains 10 mg of propylene glycol in 5 ml of solution (maximum single dose), equivalent to 2 mg/ml.

3. How to take PALEXIA

Take this medicine exactly as directed by your doctor or pharmacist. If you
have any doubts, consult your doctor or pharmacist.
Your doctor will determine the dosage based on the intensity of your pain and your individual sensitivity to pain.
In general, the lowest effective dose that relieves pain should be used.
Adults
The usual dose is 50 mg of tapentadol (2.5 ml of oral solution), 75 mg of tapentadol (3.75 ml of oral solution), or 100 mg of tapentadol (5 ml of oral solution) every 4–6 hours.
Total daily doses exceeding 700 mg of tapentadol on the first day of treatment and exceeding 600 mg of tapentadol on subsequent days are not recommended.
Your doctor may prescribe a different dosage or dosing interval if necessary. If you feel that the effect of this medicine is too strong or too weak, consult your doctor or pharmacist.
Elderly patients
In elderly patients (over 65 years of age), dosage adjustment is generally not required. However, excretion of tapentadolo may be slowed in some individuals in this age group. If this applies to you, your doctor may prescribe a different dosage.
Hepatic and renal impairment (insufficiency)
Patients with severe liver problems must not take this medicine. If you have mild liver problems, dosage adjustment is not necessary. For moderate liver impairment, your doctor will prescribe an adjusted dosage.
Patients with severe kidney problems must not take this medicine. For mild or moderate renal impairment, dosage adjustment is not necessary.
Use in children and adolescents
Palexia should be administered to children only in a hospital setting.
Palexia should only be given to children weighing more than 16 kg.
The dosage of Palexia in children and adolescents aged 2 years up to but less than 18 years is 1.25 mg/kg every 4 hours.
Always wait 4 hours before administering the next dose. The dose may be reduced as acute pain decreases.
The correct dosage will be determined by the doctor.
Hepatic and renal impairment (insufficiency) in children and adolescents
Children and adolescents with liver or kidney problems must not take this medicine.
How and when to take Palexia
Palexia is for oral use.
You may take the oral solution on an empty stomach or with food.
The package contains an oral dosing syringe with an attached adapter, which must be used to withdraw the exact amount (volume) corresponding to the prescribed dose of tapentadol from the bottle.
Instructions for opening the bottle and using the dosing syringe

The bottle is equipped with a child-resistant cap. To remove the cap, press down firmly and turn counterclockwise (Fig.1). Remove the cap and discard the seal from the bottle neck. If the seal is damaged, do not use the medicine and contact your pharmacist.
Place the bottle on a stable, flat surface. Open the plastic pouch containing the

dosing syringe/adapter along the perforated line, and remove the dosing syringe (A) with the adapter attached (B). Firmly insert the dosing syringe, with the adapter end first, into the neck of the bottle (Fig.2).

To fill the dosing syringe, turn the bottle upside down. While holding the syringe steady, pull the plunger (C) down until the mark corresponding to the prescribed dose is reached (see section “How to use Palexia”). Do not remove the syringe at this stage! (Fig.3)

Turn the bottle upright again, then carefully remove the dosing syringe from the bottle. After removing the syringe, carefully check that you have drawn up the correct dose of solution. The adapter (B), which was previously attached to the dosing syringe, will remain on the bottle (Fig.4).
Take the medicine by placing the dosing syringe in your mouth and pushing the plunger.

Push the plunger fully to ensure that all the solution has been used. If preferred, you may dilute the medicine in a glass of water or non-alcoholic drink before taking it; in this case, drink the entire glass to ensure you receive the full dose (Fig.5).
Leave the adapter on the bottle, close the cap securely, and store the bottle upright. Rinse the dosing syringe with water after use and allow it to dry thoroughly. When taking the medicine next time, insert the dosing syringe into the adapter on the bottle neck and follow the instructions above.
How long to take Palexia
Do not take this medicine longer than prescribed by your doctor.
If you take more Palexia than you should:
After taking very high doses, the following may occur:

• Pinpoint pupils, vomiting, low blood pressure, rapid heartbeat, collapse, disturbances of consciousness or coma (deep unconsciousness), seizures, breathing becoming dangerously slow and shallow, or respiratory arrest. In such cases, seek immediate medical help.

If you forget to take Palexia
If you forget to take this medicine, your pain may return. Do not take a double dose to make up for the missed dose. Simply continue taking the medicine as before.
If you stop taking Palexia
If you stop or discontinue treatment too early, your pain may return. If you wish to stop treatment, consult your doctor first.
Generally, withdrawal effects do not occur when treatment is stopped. However, in uncommon cases, individuals who have taken the medicine for a prolonged period may feel unwell if treatment is stopped abruptly.
Symptoms may include:

• Restlessness, tearing, runny nose, yawning, sweating, chills, muscle pain, and dilated pupils
• Irritability, anxiety, backache, joint pain, weakness, abdominal cramps, difficulty sleeping, nausea, loss of appetite, vomiting, diarrhea, and increased blood pressure, breathing rate, or heart rate. If you experience any of these symptoms after stopping treatment, consult your doctor. Do not stop taking this medicine abruptly unless otherwise instructed by your doctor. If your doctor advises stopping treatment, they will guide you on how to do so, which may include gradually reducing the dose.

If you have any doubts about how to use this medicine, consult your doctor or pharmacist.
