Irritant drugs can produce local phlebitis. Alterations of thermoregulation by anticholinergic agents, amphetamines including Ecstasy, and serotoninergic agents are all important causes of drug-induced (ever. Antituberculous agents and anticonvulsants are implicated in fever due to hypersensitivity reactions; and some drugs can cause severe hyperthermia in susceptible individuals, for example anaesthetic agents in patients predisposed to malignant hyperthermia.
