IMPORTANT WARNING: Return to top

Posted 05/02/2007 FDA notified healthcare professionals that the Agency proposed that makers of all antidepressant medications update the existing black box warning on the prescribing information for their products to include warnings about the increased risks of suicidal thinking and behavior in young adults ages 18 to 24 years old during the first one to two months of treatment. The proposed labeling changes also state that scientific data did not show this increased risk in adults older than 24 years of age and that adults 65 years of age and older taking antidepressants have a decreased risk of suicidality. The proposed updates apply to the entire category of antidepressants. Individuals currently taking prescribed antidepressant medications should not stop taking them and should notify their healthcare professional if they have concerns. Manufacturers of antidepressant medications will have 30 days to submit their revised product labeling and revised Medication Guides to FDA for review. See the FDA press release for the list of products affected by the proposed antidepressant product labeling changes.

Selegiline is used to help control the symptoms of Parkinson's disease (PD; a disorder of the nervous system that causes difficulties with movement, muscle control, and balance) in people who are taking levodopa and carbidopa combination (Sinemet). 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? Return to top

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.

If you are taking the orally disintegrating tablet, do not remove the blister that contains the tablets from the outer pouch until you are ready to take a dose. When it is time for your dose, remove the blister card from the outer pouch and use dry hands to peel open one blister. Do not try to push the tablet through the foil. Place the tablet on your tongue and wait for it to dissolve. Do not swallow the tablet. Do not eat or drink anything for 5 minutes before you take the tablet and for 5 minutes after you take the tablet.

If you are taking the orally disintegrating tablet, your doctor may start you on a low dose of selegiline and increase your dose after six weeks.

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.
