EPS are commonly associated with first-generation (typical) antipsychotics but can also occur with second-generation (atypical) antipsychotics and some antiemetics.
Symptoms of EPS include dystonia, akathisia, parkinsonism, and tardive dyskinesia.
EPS are often managed with dose reduction or discontinuation of the offending drug, or the use of anticholinergic medications like benztropine and diphenhydramine.
