Extrapyramidal symptoms (EPS) rates with INVEGA® were similar to those with placebo at 6 weeks*

Incidence of EPS related adverse events at 6 weeks
Incidence of EPS related adverse events at 6 weeks

  • In the 2 studies for the treatment of schizoaffective disorder, there was:
    • No dose-related increase in EPS observed for parkinsonism or akathisia
    • A dose-related increase observed with spontaneous EPS reports of hyperkinesia and dystonia and in the use of anticholinergic medications
  • Tardive dyskinesia (TD): TD is a syndrome of potentially irreversible, involuntary, dyskinetic movements that may develop in patients treated with antipsychotic drugs. The risk of developing TD and the likelihood that dyskinetic movements will become irreversible are believed to increase with duration of treatment and total cumulative dose, but can develop after relatively brief treatment at low doses. Elderly women patients appear to be at an increased risk for TD, although it is impossible to predict which patients will develop the syndrome. Prescribing should be consistent with the need to minimize the risk of TD. Discontinue drug if appropriate. The syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn.
