Your medicine

Madopar contains two medicines – Benserazide and levodopa. They both work together to increase the levels of dopamine in the brain. Madopar is used to treat Parkinson's disease and its associated symptoms which may help you to become more active. You should take care to increase your level of activity gradually as a sudden increase in your level of daily activity may increase your chances of having an accident.

Stopping your medicine
