Acute Dystonia With Rhabdomyolysis Induced by Paliperidone Palmitate: A Rare Adverse Effect.

Antipsychotic medications have been well-established to potentially cause extrapyramidal side effects (EPS) including hyperkinesia, tremor, dyskinesia, dystonia, and parkinsonism. Rhabdomyolysis secondary to extrapyramidal symptoms in patients under antipsychotics is a relatively rare presentation to be observed in patients.  In this report, we present a 64-year-old female with rhabdomyolysis following a once-monthly injection of long-acting injectable (LAI) paliperidone palmitate (Invega Sustenna).
