Parkinson’s Disease: Understanding Your Medications

Medicines are key to treating Parkinson’s. You may be prescribed one or more medicines. Be sure you know the names of your medicines and when and how to take them. Ask your healthcare provider what side effects you might expect. Also ask if you should avoid eating certain foods or drinking alcohol.
