Methylphenidate is one of the agents used in the treatment of attention deficit hyperactivity disorder. In the literature, the following side effects were reported from the use of methylphenidate: sleep and appetite problems, blood pressure and heart rate changes, headache, nervousness, crying, tics, chorea, psychosis, and rarely dystonic reaction. Acute dystonia is a well-known extrapyramidal side effect of dopamine receptor antagonists. Oculogyric crisis, a specific form of acute dystonic reaction, refers to usually upward and sometimes lateral deviation of the eyes for a certain period due to contraction of the extraocular eye muscles. Despite the increase in dopamine-related activity, psychostimulants are also reported to cause dystonic reactions rather than blocking. In this study, a patient with oculogyric crisis after the initiation of methylphenidate treatment was analyzed. Although rarely observed, dystonic reactions that may occur after methylphenidate use should be considered by clinicians.
