• if you have a severe liver disorder
• if you have epilepsy that is not adequately controlled by your current medicine.

Talk to your doctor before taking TRAMACET if you

• take other medicines containing paracetamol or tramadol
• have liver problems or disease as your eyes and skin may turn yellow, which may suggest jaundice
• have kidney problems
• have severe difficulties in breathing, for example asthma or severe lung problems
• have epilepsy or have already experienced fits or seizures
• suffer from depression and you are taking antidepressants as some of them may interact with tramadol (see “Other medicines and TRAMACET”);
• have recently suffered from a head injury, shock or severe headaches associated with vomiting (being sick)
• are dependent on any medicine (for example morphine)
• take other medicines to treat pain that contain buprenorphine, nalbuphine or pentazocine
• are going to have an anaesthetic. Tell your doctor or dentist that you are taking TRAMACET.

Sleep-related breathing disorders

TRAMACET contains an active substance that belongs to the group of opioids. Opioids can cause sleep-related breathing disorders, for example central sleep apnea (shallow/pause of breathing during sleep) and sleep-related hypoxemia (low level of oxygen in the blood).

The risk of experiencing central sleep apnea is dependent on the dose of opioids. Your doctor may consider decreasing your total opioid dosage if you experience central sleep apnea.

There is a small risk that you may experience a so-called serotonin syndrome that can occur after having taken tramadol in combination with certain antidepressants or tramadol alone. Seek medical advice immediately if you have any of the symptoms related to this serious syndrome (see section 4 “Possible side effects”).

Tramadol is transformed in the liver by an enzyme. Some people have a variation of this enzyme and this can affect people in different ways. In some people, they may not get enough pain relief but other people are more likely to get serious side effects. If you notice any of the following side effects, you must stop taking this medicine and seek immediate medical advice: slow or shallow breathing, confusion, sleepiness, small pupils, feeling or being sick, constipation, lack of appetite.

If any of the above-mentioned points applied to you in the past or applies to you while you are taking TRAMACET, please make sure your doctor knows. He/she can then decide whether you should continue to use this medicine.

Use in children with breathing problems:

Tramadol is not recommended in children with breathing problems, since the symptoms of tramadol toxicity may be worse in these children.

Talk to your doctor if you experience any of the following symptoms while taking TRAMACET:

Extreme fatigue, lack of appetite, severe abdominal pain, nausea, vomiting or low blood pressure. This may indicate that you have adrenal insufficiency (low cortisol levels). If you have these symptoms, contact your doctor, who will decide if you need to take hormone supplement.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Your doctor will tell you which medicines are safe to take with TRAMACET.

Do not exceed the maximum daily doses of paracetamol or tramadol from this or other medicines.

Do not take TRAMACET with MAOIs (see section ‘Do not take TRAMACET’).

TRAMACET is not recommended to be taken with the following:

• carbamazepine (a medicine used to treat epilepsy or some types of pain)
• buprenorphine, nalbuphine or pentazocine (opioid-type pain relievers).

Please inform your doctor or pharmacist if you are taking:

• flucloxacillin (antibiotic), due to a serious risk of blood and fluid abnormality (high anion gap metabolic acidosis which occurs when there is an increase in blood plasma acidity) that must have urgent treatment and which may occur particularly in case of severe kidney or liver impairment, sepsis (when bacteria and their toxins circulate in the blood leading to organ damage), malnutrition, chronic alcoholism, and if the maximum daily doses of paracetamol are used, especially if you take the maximum daily dose of paracetamol for longer time. High anion gap metabolic acidosis is a serious disease that must have urgent treatment.

The risk of side effects increases,

• if you are taking triptans (used for migraine) or selective serotonin re-uptake inhibitors (SSRIs, used for depression). Check with your doctor if you experience confusion, restlessness, fever, sweating, uncoordinated movement of limbs or eyes, uncontrollable jerking of muscles or diarrhoea.
• if you are taking other pain relievers such as morphine and codeine (also as cough medicine), baclofen (a muscle relaxant), medicines used to lower blood pressure, or medicines to treat allergies. Check with your doctor if you feel drowsy or feel faint.
  Concomitant use of TRAMACET and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible. However if your doctor prescribes TRAMACET together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.
  Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.
• if you are taking medicines which may cause convulsions (fits), such as certain antidepressants or antipsychotics. The risk having a fit may increase if you take TRAMACET at the same time.
  Your doctor will tell you whether TRAMACET is suitable for you.
• if you are taking certain antidepressants, TRAMACET may interact with these medicines and you may experience serotonin syndrome (see section 4 “Possible side effects”).
• if you are taking warfarin or phenprocoumon (for blood thinning). The effectiveness of such medicines may be altered and bleeding may occur (see section 4).

The effectiveness of TRAMACET may be altered if you also take the following medicines:

• metoclopramide, domperidone or ondansetron (medicines used to treat nausea and vomiting/being sick)
• cholestyramine (medicine used to reduce cholesterol in the blood)

Do not drink alcohol while you are taking TRAMACET, as you may feel drowsier.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Do not take TRAMACET while you are pregnant or breast-feeding.

Check with your doctor if you become pregnant during treatment with TRAMACET and before taking any further tablets.

Breast-feeding

Tramadol is excreted into breast milk. For this reason, you should not take TRAMACET more than once during breast-feeding, or alternatively, if you take TRAMACET more than once, you should stop breast-feeding.

Based on human experience tramadol is suggested not to influence female or male fertility. No data on the influence of the combination of tramadol and paracetamol on fertility are available.

Ask your doctor or pharmacist for advice before taking any medicine.

If you feel drowsy while taking TRAMACET, do not drive, use tools or use machinery.

The medicine can affect your ability to drive as it may make you sleepy or dizzy.

• Do not drive while taking this medicine until you know how it affects you.
• It is an offence to drive if this medicine affects your ability to drive.
• However, you would not be committing an offence if:
  • The medicine has been prescribed to treat a medical or dental problem and
  • You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and
  • It was not affecting your ability to drive safely

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

• The medicinal product contains the colorant sunset yellow (E110) which may cause allergic reactions.
• This medicinal product contains 179.3 mg sodium (main component of cooking/table salt) in each effervescent tablet. This is equivalent to 9.0% of the recommended maximum daily dietary intake of sodium for an adult. Talk to your doctor or pharmacist if you need 2 or more tablets daily for a prolonged period, especially if you have been advised to follow a low salt (sodium) diet.
• The orange flavour in this medicinal product contains low amounts of sulphite which may rarely cause severe hypersensitivity reactions and bronchospasm.

The recommended starting dose, unless otherwise prescribed by your doctor is 2 effervescent tablets for adults and adolescents over 12 years.

If required, further doses may be taken, as instructed by your doctor.

The shortest time between doses must be at least 6 hours.

Do not take more than 8 tablets per day.

• not recommended.

In elderly patients (above 75 years) the excretion of tramadol may be delayed. If this applies to you, your doctor may recommend prolonging the dosage interval.

Patients with severe liver and/or kidney insufficiency should not take TRAMACET. If in your case the insufficiency is mild or moderate, your doctor may recommend prolonging the dosage interval.

The effervescent tablets are for oral use.

Take effervescent tablets by dissolving in a glass of drinking water.

If you think that the effect of TRAMACET is too strong (you feel very drowsy or have difficulty breathing) or too weak (you do not have enough pain relief), contact your doctor.

Talk to a doctor at once if you take too much of this medicine even if you feel well. This is because too much paracetamol can cause delayed, serious liver damage.

If you forget to take the tablets, pain is likely to return.

Do not take a double dose to make up for forgotten individual doses; simply continue taking the tablets as before.

You should not suddenly stop taking this medicine unless your doctor tells you to. If you want to stop taking your medicine, discuss this with your doctor first, particularly if you have been taking it for a long time. Your doctor will advise you when and how to stop, which may be by lowering the dose gradually to reduce the chance of developing unnecessary side effects (withdrawal symptoms).
