What should I watch for while using this medicine?

Visit your doctor or health care professional for regular checks on your progress. It may be several weeks or months before you feel the full benefits of this medicine. Continue to take your medicine on a regular schedule. Do not take any additional medicines for Parkinson's disease without first consulting with your health care provider.

You may experience a wearing of effect prior to the time for your next dose of this medicine. You may also experience an on-off effect where the medicine apparently stops working for anything from a minute to several hours, then suddenly starts working again. Tell your doctor or health care professional if any of these symptoms happen to you. Your dose may need to be changed.

A high protein diet can slow or prevent absorption of this medicine. Avoid high protein foods near the time of taking this medicine to help to prevent these problems. Take this medicine at least 30 minutes before eating or one hour after meals. You may want to eat higher protein foods later in the day or in small amounts. Discuss your diet with your doctor or health care professional or nutritionist.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can make you more drowsy and dizzy. Avoid alcoholic drinks.

If you find that you have sudden feelings of wanting to sleep during normal activities, like cooking, watching television, or while driving or riding in a car, you should contact your health care professional.
