Selegiline is a medicine used to manage Parkinson's disease. By supporting natural chemical levels in the brain, Selegiline helps improve how signals travel to your muscles.
Selegiline is a monoamine oxidase-B inhibitor. It reduces dopamine breakdown in the brain and appears in products such as Eldepryl. Clinicians use it in selected Parkinson's disease care plans.
When daily activities become harder to manage, many people turn to medicines that may help with the symptoms of Parkinson’s disease. Selegiline is also used to support mood in certain cases of depression, and it can aid in managing the “off” periods that sometimes follow other Parkinson’s treatments. In some situations, doctors may add it to help reduce tremors, improve stiffness, or enhance overall movement. It is generally considered for adults who are experiencing early signs of these conditions.
Imagine dopamine as a messenger that keeps your muscles moving smoothly and your mood balanced. Once selegiline enters your system, it blocks an enzyme that would normally break down dopamine, allowing more of this messenger to linger and do its job.
By preserving dopamine, the medicine can help maintain steadier movement and smoother mood swings without over-stimulating other brain pathways.
If you are pregnant, planning a pregnancy, or breastfeeding, you should use extra caution with any medication that affects brain chemistry. People with a history of severe allergic reactions to similar drugs, or those with certain heart or liver conditions, may also need to be careful.
Alcohol, other antidepressants, certain pain relievers, and some cough medicines can interact with selegiline. Always check the label of your specific product for a full list of possible interactions.
Older adults and people who take multiple medicines that affect the brain’s chemistry may notice side effects more often. Those with liver problems can also be more susceptible. If you fall into these groups, keep an eye on any new symptoms and discuss them with a health professional.
Store your selegiline product at room temperature, away from direct sunlight and moisture, just like the instructions on the Eldepryl packaging advise. Most forms are intended for long-term use, but the exact length of therapy can differ between products. Remember that individual medicines containing selegiline may vary in strength and administration directions.
For Selegiline-specific instructions, refer to the medication information supplied with the product.
MAO-B inhibitor: A type of medicine that blocks an enzyme (MAO-B) that breaks down dopamine, helping more of this brain chemical stay active. Dopamine: A natural chemical messenger in the brain that helps control movement and mood. Neurotransmitter: A molecule that carries signals between nerve cells, allowing the brain to communicate with the body.
