Serious allergic reaction

In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to tramadol.

Call 999 now if:

• your lips, mouth, throat or tongue suddenly become swollen
• you're breathing very fast or struggling to breathe (you may become very wheezy or feel like you're choking or gasping for air)
• your throat feels tight or you're struggling to swallow
• your skin, tongue or lips turn blue, grey or pale (if you have black or brown skin, this may be easier to see on the palms of your hands or soles of your feet)
• you suddenly become very confused, drowsy or dizzy
• someone faints and cannot be woken up
• a child is limp, floppy or not responding like they normally do (their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head or focus on your face)

You or the person who's unwell may also have a rash that's swollen, raised, itchy, blistered or peeling.

These can be signs of a serious allergic reaction and may need immediate treatment in hospital.

Long-term side effects

Some people with severe pain may need to take tramadol for a long time.

If you need to take it for a long time your body can become used to it (tolerance). That means you need higher doses to control your pain over time.

With long-term use, some people become more sensitive to pain (hyperalgesia). If this happens, your doctor will reduce your dose gradually to help these symptoms.

It's possible to become addicted to tramadol. For this reason, your dose will be reviewed to make sure you're only having the amount you need to control your pain.

Your treatment plan may include details of how and when to stop taking tramadol.

If you're having treatment for cancer pain or other severe pain, your pain control will be carefully monitored. Speak to your doctor if you're worried about tolerance, hyperalgesia or becoming addicted.
