pimavanserin
Summary
Pimavanserin is used to treat hallucinations and delusions, which are false beliefs or perceptions, associated with Parkinson's disease psychosis. This condition involves seeing or hearing things that aren't there, often causing distress and confusion.
Pimavanserin works by affecting serotonin receptors, which are parts of the brain involved in mood and perception. It helps reduce hallucinations and delusions by adjusting these receptors, similar to turning down the volume on a radio to reduce noise.
The usual starting dose of Pimavanserin for adults is 34 mg taken once daily. It is typically taken as a pill, with or without food, and does not usually require dose adjustments for special populations like the elderly.
Common side effects of Pimavanserin include nausea, which is an upset stomach, and peripheral edema, which is swelling in the limbs. These effects are generally mild and manageable with the help of a doctor.
Pimavanserin may increase the risk of death in elderly patients with dementia-related psychosis, which is a mental disorder causing confusion and memory loss. It is not approved for this use. Always discuss risks with your doctor before starting.
