1.    What Zamadol SR is and what it is used for

Zamadol SR belongs to a group of medicines called analgesics, commonly known as pain killers or pain relievers. The active substance, tramadol hydrochloride, interrupts the pain messages being sent to your brain, and it also acts in your brain to stop pain messages from being felt. This means that Zamadol SR does not stop the pain from happening, but you will not be able to feel the pain as much.

Zamadol SR is used to relieve moderate to severe pain (for example pain after an operation, or after an injury).

2.    Before you take Zamadol SR

Do not take Zamadol SR:

■    if you are allergic (hypersensitive) to tramadol hydrochloride or to any of the other ingredients resulting in a skin rash, swelling of face or difficulty in breathing (see section 6, "Further Information")

■    if you are taking, or you have taken in the last two weeks, monoamine oxidase inhibitors (MAOIs) to treat your depression (see section 2, "Taking other medicines")

■    if you have epilepsy which is not controlled by treatment

■    if you have drunk enough alcohol to make you feel woozy or drunk

■    if you have taken more than the prescribed dose of your sleeping tablets, antipsychotics, antidepressant (antipsychotics and antidepressants are medicines that affect mood and emotions) or other pain killers, which can slow down your breathing and reactions.

Take special care with Zamadol SR

■    If taken for long periods there is the rare possibility that addiction may develop.

■    There is the rare possibility that Zamadol SR may cause convulsions (fits). The risk is increased if doses above the daily maximum are taken and if you are also taking antidepressants or antipsychotics.

■    If you have a tendency to drug addiction or abuse you should take Zamadol SR for short periods only. Please tell your doctor about this as he/she may want to monitor your pain control more closely.

■    You should not take this product for the treatment of withdrawal symptoms in drug addicts.

Before taking Zamadol SR you must tell your doctor:

■    if you are pregnant or breast-feeding.

■    if you have been taking Zamadol SR or any other tramadol containing medicine for a long time.

■    if you are addicted to morphine.

■    if you have had an allergic reaction to any morphine-like medicines.

■    if you have severe problems with your liver or kidneys.

■    if you have recently had a head injury or have a very bad headache that makes you sick.

■    if you have ever had convulsions (fits) or you suffer from epilepsy.

■    if you have asthma or trouble breathing.

■    if you are taking other medicines.

■    if you are going to have surgery requiring a general anaesthetic.

If any of the above apply to you, you must tell your doctor as he/she may decide to alter your treatment.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including those obtained without prescription:

■    Do not take Zamadol SR at the same time, or within 14 days of taking medicines called monoamine oxidase inhibitors (moclobemide or phenelzine for depression, selegiline for Parkinson's disease).

■    The pain relieving effect of Zamadol SR may be weakened and/or shortened if you also take medicines containing:

■    Carbamazepine (used to treat epilepsy)

■    Buprenorphine, nalbuphine, or pentazocine (pain killers)

■    Ondansetron (prevents nausea)

Your doctor will tell you whether you should take Zamadol SR, and what dose.

■    The risk of side effects increases if you are taking certain antidepressants. Zamadol SR may interact with these medicines and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38°C. You must tell your doctor if you are taking these medicines.

■    The risk of side effects increases if you are taking medicines which may cause convulsions (fits), such as certain antidepressants or antipsychotics. The risk of having a fit may increase if you take Zamadol SR at the same time. Your doctor will tell you whether Zamadol SR is suitable for you.

■    Medicines that act on the nervous system such as hypnotics, tranquillisers, sleeping pills and pain killers may make you feel drowsier or faint when taken with Zamadol SR.

■    Anticoagulants to thin your blood such as warfarin. The effectiveness of the medicines may be altered if you are also taking Zamadol SR.

Tell your doctor or dentist if you are taking any of these medicines.

Dosage for adults:

Always take Zamadol SR exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

The usual initial dose is 50-100mg twice daily, morning and evening. Your doctor may increase this dose up to 150-200mg twice daily according to your needs. You should normally take your Zamadol SR every 12 hours, at the same time each morning and evening.

The dosage should be adjusted to the intensity of your pain and your individual pain sensitivity. In general the lowest pain-relieving dose should be taken.

The maximum dose is usually 400mg daily.

Dosage for children and adolescents:

Over 12 years - as for adults (see above).

Under 12 years - Zamadol SR should not be taken by children under 12.

Dosage for elderly patients:

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.

Severe liver or kidney disease (insufficiency)/dialysis patients:

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

Ask your doctor or pharmacist if:

■    you are not sure how many capsules to take or when to take them

Tell your doctor or pharmacist if

■    you think that the effect is too strong or too weak

Swallow the capsules whole with water without chewing.

If you have difficulty in swallowing, you may open the capsules. You must open them very carefully by pulling and twisting each end over a spoon so that all the pellets stay in the spoon. Do not chew. Swallow all the pellets with water.

If you take more Zamadol SR than you should

If you accidentally take more capsules than your prescribed dose, tell your doctor or pharmacist immediately and if necessary contact your nearest hospital casualty department. Remember to take the pack and any remaining medicines with you.

If you forget to take Zamadol SR

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

dose.

If you stop taking Zamadol SR

Do not stop taking Zamadol SR, or lower the dose, without first checking with your doctor. Generally there will be no after-effects when treatment with Zamadol SR is stopped. However, on rare occasions, people who have been taking Zamadol SR for some time may feel unwell if they abruptly stop taking them. They may feel agitated, anxious, nervous or shaky. They may be hyperactive, have difficulty sleeping and have stomach or bowel disorders. If you experience any of these complaints after stopping Zamadol SR please consult your doctor.

If you have further questions on the use of this product, ask your doctor or pharmacist.
