Acute dystonic reaction is an extrapyramidal side effect, caused by  atypical antipsychotic drugs, that usually occurs suddenly. It may occur during antipsychotic treatment with pharmacological doses or after the patient  takes an overdose. It is characterized by involuntary, continuous or spasmodic muscular contractions usually on the head or the neck region. Laryngeal muscle spasm may produce respiratory distress and asphyxia. Laryngeal dystonia is a very rare and  life-threatening condition. The differential diagnosis is a challenging problem that should be treated immediately. Herein, we report a patient who presented with acute dystonic reaction on the head and  the neck region due to high dose risperidon intake.
