1. What ADOLONTA RETARD 50 MG is and what it is used for

Tramadol – the active substance in Adolonta Retard 50 mg – is an analgesic belonging to the opioid group that acts on the central nervous system. It relieves pain by acting on specific nerve cells in the spinal cord and brain.

Adolonta Retard 50 mg is indicated for the treatment of moderate to severe pain.

2. What you need to know before taking ADOLONTA RETARD 50 MG

Do not take Adolonta retard 50 mg

• If you are allergic to tramadol or to any of the other ingredients of this medicine (listed in section 6).
• In cases of acute intoxication due to alcohol, sleeping medications, analgesics, or psychotropic medicines (medicines that affect mood and emotions).
• If you are currently taking monoamine oxidase inhibitors (MAOIs) (a specific type of medicine used to treat depression), or if you have taken them within the last 14 days before starting treatment with Adolonta retard 50 mg (see "Taking Adolonta retard 50 mg with other medicines").
• If you have epilepsy and your seizures are not adequately controlled by treatment.
• For the treatment of withdrawal syndrome.

Warnings and precautions

Consult your doctor before starting to take Adolonta retard 50 mg if:

• You have disturbances of consciousness (if you feel you might faint).
• You are in shock (a sign of this condition may be cold sweating).
• You have increased pressure inside the skull (for example, after a head injury or brain diseases).
• You have difficulty breathing.
• You have epilepsy or suffer from seizures, as the risk of seizures may increase.
• You have depression and are taking antidepressants, as some of them may interact with tramadol (see "Taking Adolonta retard 50 mg with other medicines").
• You have liver or kidney disease.

Tolerance, dependence, and addiction

This medicine contains tramadol, which is an opioid medicine. Repeated use of opioids may cause the medicine to become less effective (the body becomes accustomed to it, known as pharmacological tolerance). Repeated use of Adolonta retard 50 mg may also lead to dependence, abuse, and addiction, which could result in a potentially fatal overdose. The risk of these adverse effects may be higher with higher doses and prolonged use.

Dependence or addiction may cause a feeling of lack of control over the amount of medicine you need to take or how often you need to take it.

The risk of dependence or addiction varies from person to person. The risk of becoming dependent or addicted to Adolonta retard 50 mg may be higher if:

• You or any member of your family have abused or been dependent on alcohol, prescription medicines, or illegal drugs ("addiction").
• You are a smoker.
• You have ever had problems with your mood (depression, anxiety, or a personality disorder) or have received psychiatric treatment for other mental illnesses.

If you notice any of the following symptoms while using Adolonta retard 50 mg, it could be a sign of dependence or addiction:

• You need to use the medicine for longer than prescribed by your doctor.
• You need to use a higher dose than recommended.
• You are using the medicine for reasons other than those prescribed, for example, "to stay calm" or "to help you sleep".
• You have made repeated unsuccessful attempts to stop using the medicine or control its use.
• You feel unwell when you stop taking the medicine, and feel better once you take it again ("withdrawal effects").

If you notice any of these signs, consult your doctor to determine the best treatment approach for you, when it is appropriate to stop the medicine, and how to do so safely (see section 3, if you interrupt treatment with Adolonta retard 50 mg).

Sleep-related breathing disorders

Adolonta retard 50 mg contains an active substance belonging to the opioid group. Opioids may cause sleep-related breathing disorders; for example, central sleep apnea (shallow breathing or breathing pauses during sleep) and sleep-related hypoxemia (low blood oxygen levels).

The risk of experiencing central sleep apnea depends on the opioid dose. Your doctor may consider reducing the total opioid dose if you experience central sleep apnea.

There is a low risk of developing serotonin syndrome after taking tramadol in combination with certain antidepressants or tramadol used as monotherapy. Contact a doctor immediately if you experience any symptoms associated with this serious syndrome (see section 4, "Possible side effects").

Seizures have been reported in patients taking tramadol at the recommended dose. The risk may increase when the tramadol dose exceeds the recommended maximum daily dose (400 mg).

Note that Adolonta retard 50 mg may cause physical and psychological dependence. When Adolonta retard 50 mg is used for a long period, its effect may decrease, requiring higher doses (development of tolerance).

In patients with a tendency to abuse medicines or who have medicine dependence, treatment with Adolonta retard 50 mg should only be carried out for short periods and under strict medical supervision.

Also inform your doctor if any of these problems occur during treatment with Adolonta retard 50 mg or if you have ever experienced them.

Tramadol is metabolized in the liver by an enzyme. Some people have a variation of this enzyme, which may affect individuals differently. In some people, sufficient pain relief may not be achieved, while others may be more likely to experience serious adverse effects. If you experience any of the following adverse effects, you must stop taking this medicine and consult a doctor immediately: slow or shallow breathing, confusion, drowsiness, constricted pupils, general malaise, or vomiting, constipation, loss of appetite.

Inform your doctor if you experience any of the following symptoms while taking Adolonta retard 50 mg:

Extreme fatigue, loss of appetite, severe abdominal pain, nausea, vomiting, or low blood pressure. These may be signs of adrenal insufficiency (low cortisol levels). If you have these symptoms, contact your doctor, who will decide whether you need hormonal supplements.

Taking Adolonta retard 50 mg with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Concomitant treatment with Adolonta retard 50 mg and monoamine oxidase inhibitors (MAOIs) (medicines used to treat depression) should be avoided.

The analgesic effect of Adolonta retard 50 mg and its duration may be reduced if you take medicines containing:

• Carbamazepine (for epileptic seizures)
• Ondansetron (a medicine to prevent nausea)

Your doctor will advise you whether you should take Adolonta retard 50 mg and at what dose.

The risk of adverse effects increases if you are taking:

• Medicines for anxiety or insomnia (such as benzodiazepines) or medicines that may affect respiratory function (such as other opioids, certain cough medicines, some treatments for drug dependence, medicines for mental health, antiallergic medicines such as antihistamines, or alcohol), as they increase the risk of drowsiness, breathing difficulties (respiratory depression), coma, and may be potentially fatal. Because of this, concomitant use should only be considered when no other treatment options are possible. However, if your doctor prescribes this medicine together with sedative medicines, your dose and duration of concomitant treatment should be limited.

Inform your doctor about all sedative medicines you are taking and strictly follow your doctor's dosage recommendations. It may be helpful to inform your friends and family about the signs and symptoms mentioned above. Inform your doctor if you experience any of these symptoms.

• Medicines that facilitate or may cause seizures, such as certain antidepressants or antipsychotics. The risk of seizures increases if you take Adolonta retard 50 mg simultaneously with these medicines. Your doctor will advise you whether Adolonta retard 50 mg is suitable for you.
• Medicines for the treatment of depression. Adolonta retard 50 mg may interact with these medicines and you may experience serotonin syndrome (see section 4, "Possible side effects").
• Coumarin anticoagulants (medicines that prevent abnormal blood clotting), such as warfarin, together with Adolonta retard 50 mg. The effect of these medicines on blood clotting may be affected, potentially leading to bleeding.
• Gabapentin or pregabalin for the treatment of epilepsy or nerve-related pain (neuropathic pain).
• Medicines that may have anticholinergic effects, such as:
  • Medicines used to treat allergies, dizziness, or nausea (antihistamines or antiemetics);
  • Medicines for psychiatric disorders (antipsychotics or neuroleptics);
  • Muscle relaxants;
  • Medicines for Parkinson's disease.

as they may increase the risk of adverse effects such as constipation, urinary retention, dry mouth, or dry eyes.

Taking Adolonta retard 50 mg with food and alcohol

Do not consume alcohol during treatment with Adolonta retard 50 mg, as its effects may be intensified. Food does not affect the action of Adolonta retard 50 mg.

Children and adolescents

Use in children with respiratory problems:

The use of tramadol is not recommended in children with respiratory problems, as symptoms of tramadol toxicity may worsen in these children.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

There is very limited information available on the safety of tramadol in pregnant women. Therefore, you should not take Adolonta retard 50 mg if you are pregnant.

Chronic use during pregnancy may lead to withdrawal syndrome in newborns.

Tramadol may pass into breast milk. For this reason, you should not take Adolonta retard 50 mg more than once during breastfeeding; otherwise, if taken more than once, you must stop breastfeeding.

Based on human experience, tramadol is not thought to affect fertility in men and women.

Driving and using machines

Ask your doctor whether you can drive or operate machinery while taking Adolonta retard 50 mg. It is important to observe how this medicine affects you before driving or operating machinery. Do not drive or operate machinery if you feel drowsy, dizzy, have blurred or double vision, or have difficulty concentrating. Exercise particular caution at the beginning of treatment, after a dose increase, after a change in formulation, and/or when taken together with other medicines.

Adolonta retard 50 mg contains lactose. If your doctor has informed you that you have an intolerance to certain sugars, consult with him before taking this medicine.

3. How to take ADOLONTA RETARD 50 MG

Follow exactly the instructions for use of this medicine as given by your doctor. If in doubt, consult your doctor or pharmacist again.

Before starting treatment and regularly during treatment, your doctor will also explain what you can expect from using Adolonta retard 50 mg, when and for how long you should use it, when you should contact your doctor, and when you should stop using it (see also section 2).

The dose should be adjusted according to the intensity of pain and your individual sensitivity. The lowest possible dose that provides pain relief should normally be used. Do not take more than 400 mg of tramadol hydrochloride per day unless your doctor has specifically instructed you to do so.

Unless your doctor has given you different instructions, the recommended dose is:

Adults and adolescents over 12 years of age

One or two Adolonta retard 50 mg prolonged-release tablets twice daily (equivalent to 100 mg – 200 mg of tramadol hydrochloride per day), preferably in the morning and at night.

If necessary, your doctor may prescribe a different and more appropriate dose of this medicine.

If needed, the dose may be increased up to 150 mg or 200 mg twice daily (equivalent to 300 mg – 400 mg of tramadol hydrochloride per day).

Children

Adolonta retard 50 mg is not suitable for children under 12 years of age.

Elderly patients

In elderly patients (over 75 years of age), elimination of tramadol may be slower. If this applies to you, your doctor may recommend extending the dosing intervals.

Patients with hepatic or renal impairment/patients on dialysis

If you have severe liver or kidney disease, treatment with Adolonta retard 50 mg is not recommended. If you have moderate liver or kidney dysfunction, your doctor may extend the dosing intervals.

How and when to take Adolonta retard 50 mg

Adolonta retard 50 mg prolonged-release tablets are taken orally.

The tablets must always be swallowed whole, not divided or chewed, with sufficient liquid, preferably in the morning and at night. You may take the tablet on an empty stomach or with food.

How long should you take Adolonta retard 50 mg?

Adolonta retard 50 mg should not be administered for longer than strictly necessary.

If long-term treatment is required, your doctor will monitor regularly and at short intervals (if necessary with treatment interruptions) whether treatment with Adolonta retard 50 mg should continue and at what dose.

If you think that the effect of this medicine is too strong or too weak, inform your doctor or pharmacist.

If you take more Adolonta retard 50 mg than you should

If you have accidentally taken more Adolonta retard 50 mg than prescribed, you generally will not experience negative effects. Take the next dose as prescribed.

After taking very high doses, symptoms such as pupil constriction, vomiting, decreased blood pressure, increased heart rate, collapse, decreased level of consciousness up to coma (deep unconsciousness), epileptic seizures, and breathing difficulties may occur, which can lead to respiratory arrest and death. In this case, call a doctor immediately!

In case of overdose or accidental ingestion, contact your doctor, pharmacist, or call the Toxicology Information Service at 91.562.04.20, indicating the medicine and the amount taken. It is recommended to bring the medicine’s package leaflet to the healthcare professional.

If you forget to take Adolonta retard 50 mg

If you forget to take the tablets, your pain may return. Do not take a double dose to make up for missed doses; simply continue treatment as directed by your doctor.

If you stop treatment with Adolonta retard 50 mg

If you interrupt or discontinue treatment with Adolonta retard 50 mg too early, your pain is likely to return. If you wish to stop treatment due to undesirable effects, consult your doctor.

You should not stop taking this medicine suddenly unless instructed by your doctor. If you wish to stop taking the medicine, especially if you have been taking it for a long time, speak to your doctor first. Your doctor will advise you when and how to stop, which may involve gradually reducing the dose to minimize the risk of experiencing unnecessary adverse effects (withdrawal symptoms).

Generally, no undesirable effects occur when stopping treatment with Adolonta retard 50 mg. However, in rare cases, some people who have taken Adolonta retard 50 mg for some time may feel unwell when stopping abruptly. They may feel agitated, anxious, nervous, or shaky. They may feel hyperactive, have difficulty sleeping, or experience gastrointestinal or intestinal disturbances. Very rarely, some people may experience panic attacks, hallucinations, unusual sensations such as itching, tingling, and numbness, and ringing in the ears (tinnitus). Very rarely, other uncommon central nervous system (CNS) symptoms may occur, such as confusion, delirium, distorted perception of self (depersonalization), altered perception of reality (derealization), and delusions of persecution (paranoia). If you experience any of these symptoms after stopping Adolonta retard 50 mg, please consult your doctor.

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