Albendazole-induced dystonic reaction: a case report.

Drug-induced dystonic reactions are a common presentation to the emergency department and typically occur with drugs like chlorpromazine, haloperidol and metoclopramide. There are no reports in the literature of dystonic reaction caused by albendazole. We report a case of albendazole-induced acute dystonic reaction whose symptoms completely resolved after the discontinuation of the drug. Even though dystonia side effects of albendazole are rare, it can induce an alarming dystonia in some sensitive children. The mechanism of dystonia is unclear.
