Azilect (Generic Rasagiline): Complete Medication Guide
Key Takeaways
Generic rasagiline is a monoamine oxidase inhibitor (MAOI) used to treat Parkinson's disease symptoms and slow disease progression.
It may be taken alone or combined with other Parkinson's medications like levodopa.
Common side effects include headache, nausea, and dizziness; serious interactions can occur with certain foods and medications.
Dosing typically starts at 0.5 mg daily and may increase to 1 mg daily based on your response.
Always discuss rasagiline with your doctor before starting, especially if you take other medications or have certain health conditions.
Azilect (Generic Rasagiline) Overview
Generic rasagiline, sold under the brand name Azilect, is a prescription medication belonging to a class of drugs called monoamine oxidase inhibitors (MAOIs). It works by blocking the enzyme monoamine oxidase-B in the brain, which normally breaks down dopamine—a chemical essential for smooth, controlled movement. By preserving dopamine levels, rasagiline helps reduce the tremors, stiffness, and slowness associated with Parkinson's disease.
Rasagiline is approved to treat motor symptoms of Parkinson's disease in patients at early stages or those already taking levodopa (another common Parkinson's medication). Research suggests it may also slow the progression of the disease, though this benefit is most apparent when started early. Generic vs Brand Name Drugs explains how the generic form contains the same active ingredient as the brand-name version but typically costs significantly less.
As a first-line or adjunctive therapy, rasagiline offers patients another option for managing their Parkinson's symptoms. However, because it's an MAOI, it requires careful attention to diet and drug interactions to prevent dangerous side effects. This information is educational and does not replace advice from your healthcare provider.
Side Effects
Most people tolerate rasagiline well, though some experience mild side effects that often improve over time. Serious side effects are less common but require immediate medical attention.
Common Side Effects
Headache — Among the most frequently reported side effects; usually mild and manageable with rest or over-the-counter pain relief.
Nausea and vomiting — May occur especially when first starting the medication; often improves as your body adjusts.
Dizziness or lightheadedness — Can happen when standing up quickly; rise slowly from sitting or lying down.
Constipation — A common issue with Parkinson's medications; drink plenty of water and eat high-fiber foods.
Insomnia or sleep disturbances — Some people experience trouble sleeping; taking the dose in the morning may help.
Dry mouth — Staying hydrated and using sugar-free lozenges can provide relief.
Serious Side Effects
Severe high blood pressure (hypertensive crisis) — May occur when rasagiline is combined with certain foods or medications; symptoms include severe headache, chest pain, and rapid heartbeat.
Serotonin syndrome — A potentially dangerous condition that can develop when rasagiline is combined with certain antidepressants or other serotonin-raising drugs; symptoms include agitation, confusion, rapid heart rate, and muscle rigidity.
Allergic reactions — Rash, itching, swelling of the face or throat, or difficulty breathing require immediate attention.
Unusual mood or behavior changes — Including increased gambling, compulsive eating, or sexual urges; report these to your doctor right away.
When to Seek Medical Attention
Contact your healthcare provider if common side effects persist or worsen. Seek emergency care immediately if you experience severe headache, chest pain, rapid or irregular heartbeat, severe high blood pressure, muscle rigidity, confusion, or signs of an allergic reaction. Do not wait to report mood changes, unusual compulsive behaviors, or any symptom that concerns you—early reporting helps prevent serious complications.

Important: If you miss a dose, take it as soon as you remember—unless it's nearly time for your next dose, in which case skip the missed dose. Do not double up on doses. Never stop taking rasagiline without your doctor's approval, as sudden discontinuation may worsen Parkinson's symptoms. If you have questions about your specific dose, contact your healthcare provider or pharmacist.
Drug Interactions
Rasagiline is an MAOI and has significant interactions with many medications and foods. These interactions can be serious, so it's essential to tell your doctor about everything you take, including over-the-counter drugs, supplements, and herbal products.
Antidepressants (SSRIs, SNRIs, Tricyclics)
Combining rasagiline with certain antidepressants—especially selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs)—raises the risk of serotonin syndrome, a serious condition causing confusion, muscle rigidity, and rapid heartbeat. Your doctor may recommend avoiding these combinations or switching to safer alternatives.
Sympathomimetic Drugs (Decongestants, Stimulants)
Medications like pseudoephedrine (found in cold and allergy products) and stimulants can cause dangerous spikes in blood pressure when used with rasagiline. Always check the labels on over-the-counter cold and flu remedies, and inform your doctor before using any stimulant medication.
Opioid Pain Medications
Combining rasagiline with certain opioids may increase the risk of serotonin syndrome and other serious reactions. If pain medication is needed, discuss safer options with your doctor rather than stopping rasagiline.
Levodopa
When rasagiline is added to levodopa therapy, your doctor may need to reduce your levodopa dose to prevent side effects like increased dyskinesia (involuntary movements). Regular monitoring helps keep this combination safe and effective.
Tyramine-Rich Foods
Foods high in tyramine—such as aged cheeses, cured meats, fermented foods, and some soy products—can interact dangerously with rasagiline, causing severe high blood pressure. Your doctor will provide a tyramine-restricted diet list to follow while taking this medication.
Other MAOIs and Antidepressants
Never combine rasagiline with another MAOI or certain other antidepressants without explicit doctor approval. Allow at least 2 weeks between stopping one MAOI and starting another.

Generic vs Brand-Name Drugs confirms that both versions are equally effective, and choosing generic saves you significant money.
Yes, rasagiline is often combined with levodopa to improve Parkinson's symptom control. However, your doctor may reduce your levodopa dose to prevent side effects like involuntary movements. Always inform your doctor about all medications you're taking before starting rasagiline.
You must avoid high-tyramine foods, including aged cheeses, cured or processed meats, fermented foods (like soy sauce and miso), and some alcoholic beverages (especially red wine and beer). Your doctor will provide a complete tyramine-avoidance list. Accidentally consuming these foods could trigger a dangerous blood pressure spike.
Some patients notice improvement in Parkinson's symptoms within days to weeks, while others take several weeks to experience full benefits. The medication's effect on slowing disease progression develops over months. Your doctor will evaluate your response and adjust your dose if needed after 4–6 weeks.
