Neuroleptic-induced neutropenia in the elderly

J Am Geriatr Soc. 1987 Mar;35(3):248-50. doi: 10.1111/j.1532-5415.1987.tb02317.x.


A case reported here of Haloperidol-induced neutropenia demonstrates one of many important drug reactions to which the elderly may be predisposed. Neuroleptics can lead to neutropenia by toxic or immunologic mechanisms, and it is impossible to predict which patients will sustain this potentially life-threatening reaction. Fever and infection may be the only clue to this blood dyscrasias. The diagnosis of drug-induced neutropenia is largely one of exclusion coupled with the observation of increasing neutrophil counts after cessation of the drug.
