Selegiline prevents the breakdown of chemicals in the brain that are often imbalanced in people with depression.

Selegiline transdermal is used to treat major depressive disorder in adults and adolescents who are at least 12 years old.

Selegiline may also be used for purposes not listed in this medication guide.

You should not use selegiline if you have an adrenal gland tumor or if you are using certain other medicines. Many drugs can interact with selegiline, and some drugs should not be used together.

Some young people have thoughts about suicide when first using an antidepressant. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Apply the patch to clean, dry, and hairless skin on your chest, back, thigh, or the outer part of your upper arm. Press the patch firmly into place. You may leave the patch on while bathing, showering, or swimming. Remove the skin patch after 24 hours and replace it with a new one. Choose a different place on your body to wear the patch each time you put on a new one.

Wash your hands with soap and water after applying a patch, and after removing one.

If a patch falls off, try sticking it back into place. If it does not stick well, put on a new patch and leave it on only for the rest of your wearing time. Do not change your patch removal schedule.

Do not wear more than one selegiline patch at a time. Using extra skin patches will not make the medication more effective. Never cut a skin patch. While you are wearing the patch, do not expose it to sunlight or other sources of heat such as a heating pad, electric blanket, hot tub, or sauna.

If you need surgery, tell the surgeon ahead of time that you are using selegiline. You may need to stop using the medicine for at least 10 days before a planned surgery. Do not stop using selegiline without first talking to your doctor.

Store the skin patches at room temperature away from heat and moisture. Keep each patch in the foil pouch until you are ready to apply one.

Keep both used and unused selegiline skin patches out of the reach of children or pets. The amount of selegiline in a used skin patch could be fatal to a child or pet who accidentally chews on the patch. Seek emergency medical attention if this happens.
