1.

What Zytram SR tablets are and what they are used for

These tablets have been prescribed for you by your doctor to relieve moderate to severe pain over a period of
12 hours. They contain the active ingredient tramadol which belongs to a group of medicines called strong
analgesics or ‘painkillers’.
2.

Before you take Zytram SR tablets

Do not take Zytram SR tablets:
· if you are allergic (hypersensitive) to tramadol or any of the other ingredients of the tablets (see section 6
‘Further Information’);
· if you have drunk too much alcohol, or taken more than the recommended dose of sleeping tablets,
painkillers or psychotropic medicines (used to treat psychiatric or mental disorders);
· if you are taking a type of medicine known as a monoamine oxidase inhibitor (examples include
tranylcypromide, phenelzine, isocarboxazid, moclobemide and linezolid), or if you have taken this type
of medicine in the last two weeks;
· to treat withdrawal symptoms that may occur when you stop taking another strong painkiller;
· if you are under 12 years of age.
Take special care with Zytram SR tablets
Before treatment with these tablets tell your doctor or pharmacist if you:
· are or have ever been addicted to drugs;
· suffer from, or have ever suffered from epilepsy, seizures, fits or convulsions;
· have a severe headache or feel sick due to a head injury or increased pressure in your skull (for instance
due to brain disease). This is because the tablets may make symptoms worse or hide the extent of a head
injury;
· if you have severe kidney or liver problems;
· are suffering from shock (this may make you suddenly feel very light-headed, faint, cold or clammy and
look pale);
· have a condition where you breathe more slowly and weakly than expected (respiratory depression).

Taking Zytram SR tablets with other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including
medicines obtained without a prescription. If you take these tablets with some other medicines, the effect of
these tablets or the other medicine may be changed.
These tablets must not be used together with a monoamine oxidase inhibitor, or if you have taken this type
of medicine in the last two weeks (see section 2 ‘Do not take…’).
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 Zytram SR tablets at the same time. Your
doctor will tell you whether Zytram SR tablets are suitable for you.
· if you are taking certain antidepressants. Zytram SR tablets 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 38oC.
Tell your doctor or pharmacist if you are taking:
· medicines to help you sleep (for example tranquillisers, hypnotics or sedatives);
· carbamazepine to treat seizures, fits or convulsions and certain pain conditions;
· medicines to treat depression;
· medicines to treat psychiatric or mental disorders;
· ritonavir to treat HIV;
· digoxin to treat heart failure or an irregular heart beat;
· other strong analgesics or ‘painkillers’ (such as buprenorphine, nalbuphine and pentazocine);
· certain morphine-like medicines used for example, to prevent or treat coughing, or to treat the symptoms of
withdrawal;
· medicines known as barbiturates to either treat fits or to help you sleep;
· medicines known as benzodiazepines to treat anxiety or to help you sleep;
· certain medicines to prevent your blood clotting or to help thin your blood (known as coumarin
anticoagulants, for example warfarin) ;
· ondansetron to stop you feeling or being sick.

3.

How to take Zytram SR tablets

Always take these tablets exactly as your doctor has told you. The label on your medicine will tell you how
many tablets to take and how often.
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.
Adults and children over 12 years of age
The usual starting dose is one 75 mg tablet twice a day. However, your doctor will prescribe the dose required
to treat your pain. If you find that you are still in pain whilst taking these tablets discuss this with your doctor.
You should not normally take more than 400 mg a day.
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 Zytram SR tablets. If in your case the
insufficiency is mild or moderate, your doctor may recommend prolonging the dosage interval.
Children under 12 years of age
Children under 12 years of age should not take the tablets.
Do not exceed the dose recommended by your doctor. You should check with your doctor or pharmacist if
you are not sure.
Swallow your tablets whole with water. Do not crush, dissolve or chew them.
Zytram SR tablets are designed to work properly over 12 hours when swallowed whole. If a tablet is
broken, crushed, dissolved or chewed, the entire 12-hour dose may be rapidly absorbed into your body.
This can be dangerous, causing problems such as an overdose, which may be fatal.
You should take your tablets every 12 hours. For instance, if you take a tablet at 8 o’clock in the morning, you
should take your next tablet at 8 o’clock in the evening.
If you take more Zytram SR tablets than you should or if someone accidentally swallows your tablets
Call your doctor or local hospital straight away. People who have taken an overdose may feel very sleepy, sick
or dizzy. They may have seizures, fits or convulsions. They may also have breathing difficulties leading to

unconsciousness or even death and may need emergency treatment in hospital. When seeking medical
attention make sure that you take this leaflet and any remaining tablets with you.
If you forget to take Zytram SR tablets
If you remember within 4 hours of the time your tablet was due, take your tablet straight away. Take your next
tablet at your normal time. If you are more than 4 hours late, please call your doctor for advice. Do not take a
double dose to make up for a forgotten tablet.
If you stop taking Zytram SR tablets
You should not suddenly stop taking your tablets unless your doctor tells you to. If you want to stop taking
your tablets, discuss this with your doctor first. They will tell you how to do this usually by reducing the dose
gradually so you do not experience unpleasant effects. Withdrawal symptoms such as agitation, anxiety,
nervousness, difficulty in sleeping, being unusually overactive, shaking or gastrointestinal disorders e.g. upset
stomach, may occur if you suddenly stop taking these tablets.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
