Nefopam is a painkiller. It treats moderate pain, for example after an operation or a serious injury, dental pain, joint pain and muscle pain, or pain from cancer.
You can also take nefopam for other types of long-term pain when weaker painkillers no longer work.
Nefopam is available on prescription only. It comes as tablets.
Key facts
- Nefopam is usually prescribed when other painkillers such as paracetamol or anti-inflammatories such as ibuprofen or naproxen do not help your pain.
- Your pain should start to improve 1 to 2 hours after taking the tablets.
- The most common side effects of nefopam include feeling sick or dizzy. Rarely, it might colour your pee pink, but this is harmless and does not last long.
- If nefopam makes you feel sleepy or dizzy, do not drive, ride a bike, or use tools or machinery until you feel better.
- It's possible to become addicted to nefopam if you take it for a long time. It's best to take the lowest dose for the shortest time to control your symptoms.
