Two medicines, side by side

Trifluoperazine vs risperidone

Trifluoperazine and risperidone are both labeled for schizophrenia. Drugs@FDA records approvals of trifluoperazine since 1959 and of risperidone since 1993. Pharmacies paid $0.579 per trifluoperazine 2 mg tablet and $0.0368 per risperidone 0.25 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, trifluoperazine is a phenothiazine and risperidone an atypical antipsychotic.

Check it at the source: the trifluoperazine FDA label on DailyMed (effective July 22, 2025); the risperidone FDA label on DailyMed (effective May 28, 2026).
