Onapgo

(apomorphine)

Vyalev

(foscarbidopa / foslevodopa)

Summary for Onapgo

Prescription only

Onapgo (apomorphine) is used to treat motor fluctuations in adults with advanced Parkinson’s disease (PD). It works as a dopamine agonist, acting like dopamine in the brain. Onapgo (apomorphine) is a continuous infusion given under the skin using a small pump worn during the day while you're awake. Some people might need small “extra doses” from the pump for sudden "off" symptoms. Side effects can include lumps under the skin where the pump is placed, nausea, and sleepiness. Onapgo (apomorphine) can't be swapped with other apomorphine products that are taken as single, as‑needed doses.
