The name of your medicine is Nefopam hydrochloride 30mg Film-coated Tablets (referred to as Nefopam throughout this leaflet). Nefopam belongs to a group of medicines called analgesics, commonly known as pain killers or pain relievers.

The active substance, nefopam hydrochloride, interrupts the pain messages being sent to your brain, and it also acts in your brain to stop pain messages being felt. This means that Nefopam does NOT stop the pain from happening, but you will not be able to feel the pain as much.

Nefopam is used to relieve acute and chronic pain (for example pain after an operation, dental pain, joint or muscle pain, after an injury, or pain caused by cancer).

Nefopam should NOT be used to treat the pain from a heart attack.


Do not take Nefopam:

  • you are a child under 12 years old
  • if you are allergic or have ever had an allergic reaction to nefopam hydrochloride or any of the ingredients of this medicine (listed in section 6), particularly if resulting in a skin rash, swelling of the face or difficulty in breathing (see section 4, “Possible side effects”)
  • if you are taking monoamine oxidase inhibitors (MAOIs) to treat your depression (see “Other medicines and Nefopam”)
  • if you have, or have ever had, epilepsy (fits).

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Nefopam if:

  • you have severe problems with your liver or kidneys
  • you have, or have had in the past difficulty passing urine
  • you have problems with your heart
