1. What Zytram tablets are and what they are used for

These tablets have been prescribed by your doctor for the treatment of moderate to severe pain over a 24-hour period. The tablets contain tramadol as the active substance, which is a potent analgesic (or painkiller) belonging to a group of medicines called opioids.

These tablets are intended for use only in adults and adolescents over 12 years of age.

2. What you need to know before taking Zytram tablets

Do not take Zytram tablets

• If you are allergic to tramadol or any of the other components of this medicine (listed in section 6);
• If you have consumed excessive alcohol or taken higher-than-recommended doses of sleeping pills, painkillers, or psychotropic medicines (used to treat psychiatric or mental illnesses);
• If you are taking monoamine oxidase inhibitor (MAOI) medicines (for example: tranylcypromine, phenelzine, isocarboxazid, moclobemide, and linezolid), or if you have taken such medicines within the last two weeks;
• To treat withdrawal symptoms caused by stopping another strong painkiller.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take these tablets if:

• You have or have had any type of addiction to alcohol or drugs;
• You have or have had epilepsy, seizures, tremors, or convulsions;
• You suffer from severe headaches, feel unwell due to a head injury, or have increased intracranial pressure (for example, due to a brain disorder). The tablets may worsen symptoms or mask a head injury;
• You have severe liver or kidney disease;
• You are in shock (suddenly feel very dizzy, tired, cold, shaky, and pale);
• You have slow and weaker-than-normal breathing (respiratory depression);
• You suffer from depression and are taking antidepressants, as some may interact with tramadol (see "Other medicines and Zytram prolonged-release tablets");
• You suffer from constipation.

Sleep-related breathing disorders

Zytram tablets may cause sleep-related breathing disorders such as central sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low blood oxygen levels). Symptoms may include pauses in breathing during sleep, waking up at night due to difficulty breathing, 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.

Tolerance, dependence, and addiction

This medicine contains tramadol, which is an opioid medicine. Repeated use of opioids may make the medicine less effective (you become accustomed to it, known as tolerance). Repeated use of Zytram may also lead to dependence, abuse, and addiction, which could result in a potentially fatal overdose. The risk of these side effects may increase with higher doses and longer duration of use.

Dependence or addiction may make you feel that you no longer have control over how much medicine you take or how often you take it.

The risk of becoming dependent or addicted varies from person to person. You may have a higher risk of becoming dependent or addicted to Zytram if:

• You or a family member has a history of alcohol abuse or dependence;
• You are a smoker;
• You have ever had mood problems (depression, anxiety, or a personality disorder) or have received treatment from a psychiatrist for other mental illnesses.

If you notice any of the following signs while taking Zytram, it could be a sign that you have become dependent or addicted:

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

If you notice any of these signs, talk to your doctor to determine the best therapeutic strategy for your case, including when it is appropriate to stop taking the medicine and how to do so safely (see section 3, "If you stop taking Zytram").

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 notice 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.

There is a slight risk of experiencing serotonin syndrome, which may occur after taking tramadol in combination with certain antidepressants or tramadol as monotherapy. Consult a doctor immediately if you experience any symptoms related to this serious syndrome (see section 4, "Possible side effects").

Talk to your doctor or pharmacist if you experience any of the following symptoms while taking Zytram: extreme fatigue, loss of appetite, severe abdominal pain, nausea, vomiting, or low blood pressure. This may indicate adrenal insufficiency (low cortisol levels). If you experience any of these symptoms, inform your doctor, who will decide whether you need hormonal supplementation.

Occasionally, increased sensitivity to pain (hyperalgesia) may occur, which does not respond to further increases in tramadol dose, especially at high doses. It may be necessary to reduce the tramadol dose or switch to an alternative opioid.

Children and adolescents

Use in children with breathing problems

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

Other medicines and Zytram prolonged-release tablets

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicine. Taking other medicines together with these tablets may alter the effect of these tablets or of the other medicine.

The concomitant use of Zytram and sedative medicines such as benzodiazepines or related medicines increases the risk of drowsiness, breathing difficulties (respiratory depression), coma, and may be fatal. For this reason, concomitant use should only be considered when no other treatment options are possible.

However, if your doctor prescribes Zytram together with sedative medicines, your doctor should limit the dose and duration of concomitant treatment.

Inform your doctor about all sedative medicines you are taking and follow your doctor's recommendations regarding dosage. It may be helpful to inform friends or family members so they are aware of the signs and symptoms mentioned above. Inform your doctor if you experience such symptoms.

These tablets must not be used together with a monoamine oxidase inhibitor (MAOI), or if you have taken such medicines within the last 2 weeks (see section 2, "Do not take Zytram tablets").

The risk of side effects increases:

• If you are taking medicines that may cause seizures, such as certain antidepressants or antipsychotics. The risk of having a seizure may increase if you take Zytram tablets at the same time. Your doctor will inform you whether Zytram tablets are suitable for you.
• If you are taking certain antidepressants. Zytram tablets may interact with these medicines, and you may experience serotonin syndrome (see section 4, "Possible side effects").

Inform your doctor or pharmacist if you are taking:

• Sleeping medicines (tranquilizers, hypnotics, or sedatives);
• Carbamazepine for treating seizures, tremors, convulsions, and certain types of pain;
• Medicines for depression;
• Medicines for treating psychiatric or mental illnesses;
• Ritonavir for treating HIV;
• Digoxin for treating heart failure or arrhythmias;
• Other strong painkillers (buprenorphine, nalbuphine, and pentazocine);
• Certain morphine-like drugs, for example, to treat cough or withdrawal syndromes;
• Barbiturates for treating seizures or to help sleep;
• Benzodiazepines, to treat anxiety or to help sleep;
• Gabapentin or pregabalin for treating epilepsy or nerve-related pain (neuropathic pain);
• Certain medicines to prevent blood clotting or to thin the blood (coumarin anticoagulants, such as warfarin);
• Ondansetron, to treat nausea or general malaise.

Taking Zytram tablets with alcohol

Talk to your doctor or pharmacist if you drink or plan to drink alcohol while taking this medicine.

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.

Pregnancy

Do not take this medicine if you are pregnant. Depending on the dose and duration of tramadol treatment, the newborn may experience slow and shallow breathing (respiratory depression) or withdrawal symptoms.

Breastfeeding

Tramadol is excreted in breast milk. Therefore, you must not take Zytram more than once during breastfeeding, or if you take Zytram more than once, you must stop breastfeeding.

Babies born to mothers who have used Zytram prolonged-release tablets during pregnancy may experience withdrawal symptoms, including high-pitched crying, irritability and restlessness, agitation (tremors), feeding difficulties, and sweating.

Driving and using machines

These tablets may cause several side effects, such as drowsiness, blurred vision, and dizziness, which could affect your ability to drive or operate machinery (see section 4 for a complete list of side effects). These effects are more noticeable when you first start taking the tablets or when your dose is increased. If affected, you must not drive or operate machinery.

Zytram tablets contain lactose

This medicine 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 Zytram tablets

Follow exactly the instructions for use of this medicine given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist. Before starting treatment and regularly during treatment, your doctor will discuss with you what to expect from using Zytram, when and for how long you should take it, when to contact your doctor, and when you should stop taking it (see also section 2).

The dose should be adjusted according to the intensity of pain and your individual sensitivity. The lowest effective dose that provides pain relief should generally be used.

Adults and adolescents over 12 years of age

The usual initial dose is one 150 mg tablet once daily. However, your doctor will prescribe the dose required to treat your pain. Do not exceed the dose recommended by your doctor. If you still experience pain while taking the tablets, consult your doctor. Generally, you should not take more than 400 mg per day.

The tablets should be swallowed whole with water. They must not be broken, dissolved, or chewed.

Zytram tablets are designed to provide adequate treatment coverage over 24 hours when taken whole. If the tablet is broken, crushed, dissolved, or chewed, the entire 24-hour dose may be rapidly absorbed by your body, which can be dangerous and cause serious problems such as an overdose that could be fatal.

You should take the tablets at the same time each day. For example, if you took a tablet at 8 a.m., you should take the next tablet at 8 a.m. the following day.

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 reducing the dose.

Patients with hepatic or renal impairment / patients on dialysis

Zytram tablets are not recommended if you have severe liver or kidney disease. If you have mild or moderate liver or kidney disorders, your doctor may recommend reducing the dose.

Children under 12 years of age

Zytram must not be given to children under 12 years of age.

If you take more Zytram tablets than you should or someone takes them by accident

Contact your doctor or nearest hospital immediately. People who have taken an overdose may experience excessive drowsiness, feel very unwell or very dizzy, have seizures, tremors, or convulsions. They may also develop breathing difficulties that could lead to loss of consciousness or even death, and may require emergency treatment in hospital. If medical attention is needed, make sure to bring this leaflet and any remaining tablets with you.

In case of overdose or accidental ingestion, contact the Toxicology Information Service (Tel. 91.562.04.20), indicating the product and the amount ingested.

If you forget to take Zytram tablets

If you remember within 10 hours of the time the tablet was due, take the missed tablet immediately. Then take the next tablet at your usual time. If more than 10 hours have passed, it is advisable to consult your doctor.

Do not take a double dose to make up for a forgotten dose.

If you stop taking Zytram tablets

Do not stop taking this medicine suddenly unless instructed by your doctor. If you wish to stop taking the medicine, speak to your doctor first, especially if you have been taking it for a long time. Your doctor will advise you when and how to stop, which may involve gradually reducing the dose to reduce the likelihood of experiencing unnecessary adverse effects (withdrawal symptoms). If you stop taking these tablets suddenly, withdrawal symptoms such as agitation, anxiety, restlessness, difficulty sleeping, unusual hyperactivity, tremors, or gastrointestinal disturbances (e.g. upset stomach) may occur.

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