1. What Zamadol is and what it is used for
The name of your medicine is ­Zamadol® Injection (referred to as a Zamadol throughout this leaflet).
Zamadol belongs to a group of medicines called analgesics, commonly known as pain killers or painrelievers. The
active substance, tramadol hydrocloride, 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 does not stop the pain from happening,
but you will not be able to feel the pain as much.
Zamadol is used to relieve moderate to severe, a sudden or a long-standing pain (for example pain after an operation,
or after an injury).

2. Before you use Zamadol
Do not use Zamadol if:
• you are allergic (hypersensitive) to tramadol hydrochloride or to any of the other ingre dients resulting in a skin
rash, swelling in face or difficulty in breathing (see section 6. Further Information)
• you are taking, or you have taken in the last two weeks, monoamine o­ xidase inhibitors (MAOIs), these are medicines
to treat depression
• you are suffering from uncontrolled epilepsy
• you have drunk enough alcohol to make you feel woozy or drunk
• you have taken more than the prescribed dose of your sleeping tablets,antipsychotics,
antidepressants (antipsychotics and antidepressanst are medicines that affect mood and emotions) or other pain
killers, which can slow down your breathing and reactions.
(See section ‘Taking other medicines’ for details)
Take special care with Zamadol
• If taken for long periods there is the rare possibility that addiction may develop.
• There is a rare possibility that Zamadol may cause convulsions (fits). The risk is increased
if doses above the daily maximum are taken and if you are also taking anti-depressants or antipsychotics.
• If you have a tendency to drug addiction or abuse you should take Zamadol 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 caused by opiates (morphine- like
• If you have a head injury, breathing difficulties or severe liver or kidney problems.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including
medicines obtained without prescription:
• Do not use Zamadol at the same time, or within 14 days of taking medicines called monoamine o­ xidase inhibitors
or phenezeline for depression, ­selegiline for Parkinson’s disease).
• The pain relief effect of Zamadol may be weakened and/or shortened if you also take medicines containing:
– Carbamazepine (used to treat e­ pilepsy)
– Buprenorphine, nalbuphine, or pentazocine (pain killers)
– Ondanserton (prevents nausea)
• The risk of side effects increases if you are taking certain antidepressants. Zamadol 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
• 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 Zamadol injection is being administered
at the same time. Your doctor will tell you whether Zamadol injection 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.
• Anticoagulants to thin your blood such as warfarin. The effectiveness of the medicines may be altered if you are
also using Zamadol.
Tell your doctor or dentist if you are taking any of these medicines.
