Nefopam

About

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. 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. Page last reviewed: 23 April 2024 Next review due: 23 April 2027
