title: Drug-induced extrapyramidal reactions.
abstract: A child with psychotic symptoms and attention-deficit hyperactivity disorder who developed extrapyramidal symptoms while on a combination of risperidone, methylphenidate, sertraline, tropisetron and ketorolac is described herein. The extrapyramidal symptoms resolved with the administration of benztropine, an anticholinergic drug. Successful treatment of his psychosis was achieved by decreasing the dose of risperidone, followed by slow upward titration.
