title: [Toxicity of cyproheptadine. Side effects and accidental overdosage (author's transl)].
abstract: 113 cases of accidental ingestion of cyproheptadine (Nuran) by children have been evaluated. Life threatening alterations have not been observed after doses ranging from 0.3-6.15 (x:1.89) mg per kg of body weight. Somnolence, excitation, hallucinations, ataxia, tachycardia, and muscle twitchings were observed frequently, and occasionally gastric pain, dry mucuous surfaces, mydriasis, and rubeosis of the face were present. Symptoms appeared rapidly after ingestion and generally did not last longer than 6-12 h. When given in therapeutic doses, cyproheptadine reduces the secretion of ACTH, cortisol, prolactin, and growth hormone, lowers blood glucose concentrations, and raises the levels of unesterified free fatty acids. Parents frequently complain about unsatisfactory eating habits of their children, but chronic lack of appetite needing therapeutical attention, in healthy children, is the rare exception. Cyproheptadine is an agent with considerable side effects, and it should be prescribed to children only after very careful deliberation.
