What is Selegiline?
Selegiline is a prescription medication that belongs to a class of drugs called monoamine oxidase B (MAO-B) inhibitors. It is mainly used to manage symptoms of Parkinson’s disease and, in some cases, major depressive disorder.
It works by increasing levels of certain brain chemicals that help improve movement, mood, and overall neurological function.
How Selegiline Works
Selegiline works by blocking the enzyme MAO-B, which breaks down dopamine in the brain. By preventing dopamine breakdown, it helps:
- Improve movement control
- Reduce tremors and stiffness
- Enhance mood and motivation
- Support better brain function in neurological conditions
In higher doses, it may also affect serotonin and norepinephrine levels.
Uses of Selegiline
Selegiline is commonly prescribed for:
- Parkinson’s disease (early and advanced stages)
- Management of motor symptoms like tremors and rigidity
- Adjunct therapy with levodopa
- Treatment of depression (in patch form in some cases)
- Cognitive and neurological support in certain patients
Dosage Information
Dosage depends on the condition being treated and patient response.
Typical Dosage (Oral):
- Parkinson’s disease: 5 mg twice daily or 10 mg once daily (varies by formulation)
- Should be taken in the morning and early afternoon to avoid sleep disturbances
⚠️ Always follow your doctor’s exact prescription. Do not self-adjust the dose.
