Nefopam Hydrochloride is a centrally acting analgesic with a rapid onset of action. The main site of action appears to be in the central nervous system both at the brain and spinal levels. In vitro experiments have shown Nefopam to inhibit the re-uptake of various catecholamines (including noradrenaline, serotonin and dopamine). It is possible that the mechanism of action of nefopam is at least in part by altering the levels of these neuromodulators in the brain and at the spinal level.


Nefopam Hydrochloride is indicated for the relief of acute pain, including post-operative, dental, musculo-skeletal and acute traumatic pain. It is also indicated in chronic pain like cancer pain.

Use in Pregnancy & Lactation

Pregnancy: Nefopam Hydrochloride is not recommended for pregnant women.
Lactation: Evidence suggests that nefopam is excreted in human milk. A decision should made whether to discontinue nursing or discontinue the medication, taking into account the potential for adverse effects for the foetus and the importance of treatment to the mother.

Over Dose

Nefopam toxicity is manifested by neurological symptoms (convulsions, hallucinations, agitation) and cardiovascular response (tachycardia with hyperdynamic circulation). Supportive treatment is suggested including gastric lavage, forced emesis and diuresis. Oral administration of activated charcoal may help prevent absorption.
