FDA cautions that the labeling of the generic risperidone may differ from that of Risperdal.
The Food & Drug Administration has approved the first generic version for the antipsychotic Risperdal (risperidone, Janssen). Pharmacies can buy varying strengths of risperidone tablets from TEVA Pharmaceuticals USA or they can purchase an authorized generic version from Patriot Pharmaceuticals, a subsidiary of McNeil-PPC. Both Patriot and Janssen are part of Johnson & Johnson. The Food & Drug Administration cautions that the labeling of the generic risperidone may differ from that of Risperdal because some uses of the drug are protected by patents and exclusivity. Risperdal is used to treat schizophrenia, bipolar disorder, and other psychiatric conditions.
