Indications

Pimavanserin is used to treat the hallucinations and delusions that can happen with Parkinson's disease psychosis.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Nobody knows exactly how pimavanserin works in treating the hallucinations and delusions that come with Parkinson's disease psychosis. Its effect may come from a combination of inverse agonist and antagonist activity at serotonin 5-HT 2A receptors, and to a lesser extent at serotonin 5-HT2C receptors.

Pregnancy & Breastfeeding

We don't have any data on the use of Pimavanserin in pregnant women, so the risk of major congenital malformations or miscarriage from the drug can't be assessed. It is also not known whether pimavanserin passes into human milk, what effect it might have on a breastfed infant, or whether it changes milk production.

If a mother needs Pimavanserin, the benefits of breastfeeding for the baby's development and health should be weighed alongside her clinical need for the medicine. Any possible adverse effects on the breastfed infant, either from Pimavanserin or from the mother's underlying condition, should be considered as well.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
