Risperidone-Induced Tardive Akathisia: A Rare Antipsychotic Side Effect with Management Issues

Akathisia is a movement disorder, a common extrapyramidal side effect that has been reported to occur primarily with antipsychotics and some neurological conditions. It is manifested by a subjective feeling of inner restlessness along with objective evidence of motoric restlessness. Tardive akathisia (TA) is rare, and there is very sparse literature available as regards to its phenomenology and management. We report a case of TA that occurred after 10 months of starting atypical antipsychotic, risperidone, and challenges faced in management.
