What is Ongentys used for?

Ongentys (generic name Opicapone) is a once-a-day capsule used along with carbidopa and levodopa to treat adults with Parkinson's disease (PD) who are having 'off' episodes. When people have 'off' episodes, their symptoms of PD (such as tremors or stiff muscles) start to return as levodopa wears off. Ongentys can help levodopa linger in your body, so that you don’t feel tremors, slowness, or stiffness in your muscles.
