Teva-Selegiline

How does this medication work? What will it do for me?

Selegiline belongs to the class of medications called monoamine oxidase inhibitors (MAOIs). It is used to treat Parkinson's disease. It acts on the nervous system to increase the levels of a chemical called dopamine. Low dopamine levels in the brain are responsible for many of the symptoms of Parkinson's disease, so this medication works by rebalancing the levels of dopamine.

This medication may be taken alone or in combination with levodopa to treat the symptoms of Parkinson's disease.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use this medication?

The recommended adult dose of selegiline is 5 mg taken twice a day with breakfast and lunch.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones given here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose of this medication, take it as soon as possible. If you do not remember your dose until late afternoon or evening, skip the missed dose and continue with your regular schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
