Metoclopramide-induced acute dystonia in an adolescent.

Metoclopramide is a dopamine-2 antagonist and is generally used as an antiemetic in clinical practice. Extrapyramidal reactions are the important adverse effects of metoclopramide which are reported in 0.2% of cases. In young children, the incidence can extend up to 25%. Metoclopramide-induced EPS include acute dystonia, tardive dyskinesia, parkinsonism, akathisia, and malignant neuroleptic syndrome. We are reporting a single dose of metoclopramide induced acute dystonia in an adolescent girl, which caused lot of anxiety in the patient and the parents which responded to oral diphenhydramine.
