NUPLAZID® (pimavanserin) is the only treatment approved by the US Food and Drug Administration (FDA) to treat hallucinations and delusions associated with Parkinson's disease psychosis.

NUPLAZID works all day and night to help reduce the frequency and/or severity of Parkinson's disease–related hallucinations and delusions. You just take one 34 mg capsule, once daily by mouth, with or without food, around the same time every day, or as prescribed by your healthcare provider. It’s important to remember that everyone responds to medications differently, so it may take some time for NUPLAZID to start working. NUPLAZID may begin to reduce hallucinations and delusions as soon as 4 weeks, but it may take up to 6 weeks to feel the full effect. Not everyone will respond to NUPLAZID.

The common side effects of NUPLAZID include swelling in the legs or arms, nausea, confusion, hallucination, constipation, and changes to normal walking. These are not all the possible side effects of NUPLAZID. For more information, ask your healthcare provider about this medicine.
