Unprovoked Dystonic Reaction in a Child Taking Long-Term Methylphenidate

In this report, we discuss the case of a 9-year-old male with Attention Deficit Hyperactivity Disorder (ADHD) on long-term methylphenidate and guanfacine who experienced acute orofacial dystonia that resolved immediately with the administration of benztropine. Current literature describes various cases of methylphenidate-induced dystonia, but ours appears to be the first reported instance of spontaneous dystonia without a recent change in dose or medication change. This may suggest the possibility of methylphenidate-induced dystonia spontaneously occurring several years after initiation.

Acute Dystonic Reaction in a 14-Year-Old Boy after Accidental Overuse of Nasal Metoclopramide

We present the case of a 14-year-old boy who developed an acute dystonic reaction 5 h following the overuse of a nasal metoclopramide spray that his mother gave him thinking it was a nasal decongestant. The patient had torticollis and intense motor restlessness, while he was fully conscious and hemodynamically stable. All laboratory investigations were normal. He was treated with a single dose of biperiden intravenously with direct disappearance of the symptoms. Children are particularly susceptible to the extrapyramidal side effects of metoclopramide that can occur irrespective of the route of administration.
