Extrapyramidal side effects (EPS) are the various movement disorders suffered as a result of taking antipsychotic or neuroleptic drugs to control some symptoms of schizophrenia.

Common EPS are akathisia (restlessness), dystonia (muscular spasms of neck (torticollis), eyes (oculogyric crisis), tongue, or jaw), Drug-Induced Parkinsonian Syndrome (muscle stiffness, shuffling gait, drooling, tremour), and tardive dyskinesia (involuntary, irregular muscle movements, usually in the face).

Anticholinergic drugs are used to control neuroleptic-induced EPS, although akathisia may require beta blockers or even benzodiazepines.
