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. Convulsions and hallucinations may be controlled with diazepam. Beta-adrenergic blockers may be of use in controlling the cardiovascular complications.
