Parkinson's Disease - Medications

Medicines are the most common treatment for Parkinson's disease. The goal is to correct the shortage of the brain chemical dopamine, which causes the symptoms of Parkinson's.

The decision to start taking medicine, and which medicine to take, will be different for each person. Medicine is usually started when your symptoms become disabling or disrupt your daily activities.

Michael J. Fox's Crusade for a Parkinson's Cure

Michael J. Fox has always been a poster boy. With his youthful good looks and intelligent charm, he rose to fame playing a sassy Republican teenage son of ex-hippie parents in the TV sitcom Family Ties. In the blockbuster Back to the Future film trilogy, he was a time traveler with perfect comedic timing. And in a later sitcom, Spin City, he made us wish all politicians were as personable as his Deputy Mayor Mike Flaherty. In 1998, Fox became a poster boy for another reason: He went public with...

Symptoms change as the disease progresses. Because of this, your doctor will adjust your medicine to deal with the symptoms as they appear.

Medicines often improve symptoms, but they also may cause side effects. It may take some time to find the best combination of medicines for you.

Medication choices

Several medicines may be used at different stages of the disease:

Levodopa is thought to be the most effective drug for controlling symptoms. But many doctors prescribe dopamine agonists in the beginning of the disease. This is because after a few years, levodopa can cause motor complications (times when the medicine suddenly stops working or when you have uncontrollable jerking movements). Talk to your doctor about which medicines are best for you.

Although it's always important to follow your doctor's instructions when you take medicines, it's especially vital when you have Parkinson's.

Increasing, decreasing, or stopping the medicines you are taking may cause big changes in your symptoms and can be dangerous. Even if a medicine doesn't seem to be working, when you stop taking it, your symptoms of Parkinson's disease may be worse.

Taking medicine with food

Early in the disease, it might be helpful to take pills with food to help with nausea, which may be caused by some of the medicines for Parkinson's disease.

Later in the disease, taking the medicines at least 1 hour before meals (and at least 2 hours after meals) may help them work best.

Some medicines for Parkinson's disease don't work as well if you take them at the same time you eat food with protein in it, such as meat or cheese. The protein can block the medicine and keep it from working as well as it should.
