Drug-induced dyskinesias are common side-effects of first-generation antipsychotics (FGAs) but are not usually related to second-generation antipsychotics (SGAs). Oculogyric crisis (OGC) is a disabling acute dystonia that affects extra-ocular muscles usually resulting in an upward deviation of the eyes, which lasts from minutes to hours.
