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.

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
• Carbamazepine (used to treat epilepsy)
• Buprenorphine, nalbuphine, or pentazocine (pain
• 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
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.

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