Selegiline is a medication that is primarily used to treat Parkinson's disease, although it can also be used off-label for depression and other conditions (Note: selegiline patch, emsam patch, is approved for depression). Here are some important things to know about selegiline:
- Mechanism of action: Selegiline is a selective and irreversible monoamine oxidase-B (MAO-B) inhibitor. It increases the levels of dopamine in the brain by blocking its breakdown, which helps manage the symptoms of Parkinson's disease.
- Parkinson's disease: Selegiline is commonly used as an adjunct therapy to levodopa/carbidopa in the treatment of Parkinson's disease. It helps to control the motor symptoms such as tremors, rigidity, and bradykinesia.
- Interaction with other medications: Selegiline should not be taken with certain medications, including other MAO inhibitors, antidepressants such as selective serotonin reuptake inhibitors (SSRIs) or tricyclic antidepressants, and a variety of other drugs. These combinations can lead to a dangerous condition called serotonin syndrome or hypertensive crisis.
- Dietary restrictions: During selegiline treatment, it is necessary to follow dietary restrictions due to potential interactions with tyramine in certain foods and beverages. High levels of tyramine in the blood can cause a hypertensive crisis. Foods to avoid include aged cheeses, cured meats, fermented foods, certain wines, and beer.
- Selegiline Side effects: Some common side effects of selegiline may include dizziness, nausea, insomnia, dry mouth, headache, and abdominal discomfort. It may also increase the risk of hallucinations, confusion, or falls in older adults.
- Drug interactions: Selegiline can interact with a variety of medications, including antidepressants, opioids, stimulants, certain herbal supplements, and over-the-counter cough and cold medications. It is important to inform your doctor about all medications you are taking before starting selegiline.
- Need for dosage adjustment: Selegiline dosage may need to be adjusted in patients with liver or kidney impairment. It is crucial to follow your doctor's instructions and not change the dose or stop taking the medication without consulting them first.
- Potential for abuse: Selegiline has the potential for abuse, especially at higher doses. Misuse of selegiline can lead to stimulant effects, hallucinations, agitation, and other psychological disturbances.
It is essential to consult your healthcare provider for personalized information and guidance regarding the use of selegiline.
