What does it do?

Levodopa and benserazide is used to treat Parkinson’s disease, and sometimes other conditions. Levodopa changes into dopamine in your body. Dopamine helps your brain control your body movements. Benserazide helps get more levodopa into your brain.

Before you start

• Tell your doctor if you have heart or mental health problems, or if you have angle-closure glaucoma.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take levodopa and benserazide regularly as directed with a glass of water. You can take it with or without food.
