Selegiline for Parkinson’s Disease

Selegiline is used to help control the symptoms of Parkinson's disease in people who are taking levodopa and carbidopa combination.

Selegiline may help people with Parkinson's disease by decreasing the dose of levodopa/carbidopa needed to control symptoms, stopping the effects of levodopa/carbidopa from wearing off between doses, and increasing the length of time that levodopa/carbidopa will continue to control symptoms.

Selegiline is in a group of medications called monoamine oxidase type B (MAO-B) inhibitors. It works by increasing the amount of dopamine (a natural substance that is needed to control movement) in the brain.

How should this medicine be used?

Selegiline comes as a capsule and an orally disintegrating (dissolving) tablet to take by mouth. The capsule is usually taken twice a day with breakfast and with lunch. The orally disintegrating tablet is usually taken once a day before breakfast without food, water, or other liquids.

Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take selegiline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. If you take too much selegiline, you may experience a sudden and dangerous increase in your blood pressure.

Tell your doctor if you experience nausea, stomach pain, or dizziness. Your doctor may decrease your dose of levodopa/carbidopa during your treatment with selegiline, especially if you experience these symptoms or other unusual symptoms. Follow these directions carefully and ask your doctor or pharmacist if you do not know how much medication you should take. Do not change the doses of any of your medications unless your doctor tells you that you should.

Selegiline may help to control the symptoms of PD, but it will not cure the condition. Do not stop taking selegiline without talking with your doctor. If you suddenly stop taking medications for Parkinson's disease such as selegiline, you may experience fever, sweating, stiff muscles, and loss of consciousness. Call your doctor if you experience these or other unusual symptoms after you stop taking selegiline.
