HelloPharmacist Editorial Team Bottom Line
Selegiline is a helpful add-on for Parkinson's patients whose levodopa isn't working as well as it used to — it helps keep dopamine active longer in the brain. But it has serious interaction risks with many common medications, and staying within the recommended dose is critical to avoid dangerous blood pressure reactions. Always keep your whole care team in the loop about every medication and supplement you take.

📖 Selegiline: Patient Information Guide

A plain-language walkthrough of Selegiline — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for▾

Selegiline is approved as an add-on treatment for Parkinson's disease in people whose response to levodopa/carbidopa is declining. It is not used on its own. Specific benefits shown in studies include:

  • Reducing the total daily amount of levodopa/carbidopa needed
  • Cutting down "off" time — periods when Parkinson's symptoms break through between doses
  • Reducing end-of-dose akinesia (stiffness and slowness as medication wears off)
  • Decreasing tremor and drooling (sialorrhea)
  • Improving speech and ability to dress independently
  • Improving overall mobility and disability rating
⚙️How it works▾

Selegiline works by blocking an enzyme called MAO-B (monoamine oxidase type B), which normally breaks down dopamine in the brain. In Parkinson's disease, dopamine-producing cells are lost, so protecting what dopamine remains is a key strategy. By irreversibly locking onto MAO-B, selegiline slows the breakdown of dopamine, allowing it to remain active in the brain longer. There may also be additional ways it boosts dopamine activity that researchers are still studying.

At the recommended dose, selegiline targets MAO-B selectively — which matters because the other form, MAO-A, helps protect the gut and liver from blood pressure-raising substances in food. Exceeding the recommended dose erodes this selectivity and raises the risk of dangerous reactions.

💊How it's taken▾

Selegiline is taken once a day in the morning, before breakfast. The orally dissolving tablet form is placed on top of the tongue — it dissolves in seconds without water. Avoid eating or drinking for 5 minutes before and after each dose, since food can significantly reduce how much medication is absorbed.

  • Treatment is typically started at a lower dose for at least 6 weeks before any increase is considered
  • There is no evidence that going above the maximum recommended dose helps — and it significantly increases risk
  • For mild-to-moderate liver disease, a lower dose is used; the drug is not recommended in severe liver or kidney disease

Always follow your prescriber's exact instructions and do not adjust your dose on your own.

🤒Side effects — in detail▾

Like most Parkinson's medications, selegiline can cause a range of side effects — some mild, some that need prompt attention:

  • Nausea
  • Dizziness, lightheadedness, or fainting
  • Stomach pain
  • Dry mouth
  • Vivid dreams
  • Headache
  • Confusion or hallucinations
  • Uncontrolled movements (dyskinesia)

Call your doctor right away if you experience hallucinations, sudden fainting, compulsive behaviors that feel out of character, or any signs of serotonin syndrome — such as agitation, fever, rapid heart rate, or muscle rigidity. These can be serious and need fast attention.

⚠️Warnings & precautions▾
  • Tyramine and blood pressure: At doses higher than recommended, selegiline can cause dangerous blood pressure spikes after eating tyramine-rich foods (aged cheeses, cured meats, red wine). Even at the recommended dose, rare reactions have been reported. Never exceed the prescribed dose.
  • Serotonin syndrome: Combining selegiline with antidepressants (SSRIs, tricyclics) or opioids can trigger a life-threatening condition involving fever, agitation, muscle rigidity, and rapid heart rate. A 14-day washout period is required between stopping selegiline and starting these drugs.
  • Falling asleep suddenly: Selegiline may cause people to fall asleep without warning during everyday activities — including driving. Use caution until you know how it affects you.
  • Impulse control: Some people develop compulsive behaviors — gambling, spending, eating, or sexual urges — that feel difficult to control. Report any unusual behavioral changes to your doctor.
  • Don't stop abruptly: Stopping selegiline suddenly can cause high fever and confusion. Talk to your doctor before making any changes.
  • Phenylketonuria (PKU): The dissolving tablet contains phenylalanine — people with PKU must inform their doctor.
🔀What it interacts with▾

Selegiline has several serious — sometimes life-threatening — drug and food interactions. Make sure your entire care team knows everything you take:

  • Opioid painkillers (meperidine, tramadol, methadone) — can cause a fatal reaction; absolutely contraindicated, with a required 14-day gap after stopping selegiline
  • Other MAO inhibitors (including the antibiotic linezolid) — risk of hypertensive crisis; contraindicated, 14-day gap required
  • SSRIs and tricyclic antidepressants (fluoxetine, sertraline, paroxetine, amitriptyline, protriptyline) — risk of serious or fatal serotonin syndrome
  • Dextromethorphan (in many OTC cough syrups) — can cause psychosis or bizarre behavior; contraindicated
  • St. John's Wort (herbal supplement) — contraindicated due to serious interaction risk
  • Cyclobenzaprine (muscle relaxant) — contraindicated
  • Sympathomimetics like ephedrine (in some decongestants) — can cause uncontrolled high blood pressure
  • Tyramine-rich foods (aged cheese, cured meats, fermented foods, red wine, some OTC cold medicines) — can raise blood pressure dangerously, especially above recommended doses

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it▾
  • Tell your doctor about all medications, supplements, and herbal products you take — the interaction list for selegiline is long and some are life-threatening
  • Liver disease: Dose reduction needed for mild-to-moderate liver impairment; not recommended for severe liver disease
  • Kidney disease: Not recommended for severe kidney impairment or end-stage renal disease (dialysis)
  • Pregnancy: Animal studies suggest possible fetal harm — discuss the risks and benefits carefully with your doctor
  • Phenylketonuria (PKU): The orally dissolving tablet contains phenylalanine; inform your doctor if you have this condition
  • History of psychosis or hallucinations: Selegiline may worsen these symptoms
  • Low blood pressure: Selegiline can further lower blood pressure, especially when standing up
🚑If you take too much▾

There is limited real-world data on selegiline overdose, but at high doses the drug loses its MAO-B selectivity and can affect MAO-A as well, leading to a picture similar to overdose with non-selective MAO inhibitors. Symptoms may be delayed up to 12 hours and could include severe headache, agitation, hallucinations, seizures, very high or very low blood pressure, rapid or irregular heartbeat, and loss of consciousness.

If an overdose is suspected, go to the nearest emergency room immediately — the label strongly recommends at least 48 hours of continuous monitoring in a hospital setting.

📡Pharmacodynamics — effects in the body▾

At the recommended dose, selegiline selectively blocks the MAO-B enzyme, slowing the breakdown of dopamine in the brain. Studies examining higher doses showed that blood pressure sensitivity to tyramine (a substance found in certain foods) starts to increase once the dose exceeds the recommended level, because MAO-A — which protects against tyramine absorption — begins to be inhibited as well. This is why staying within the prescribed dose range is so important: going above it shifts the drug from a targeted brain therapy to a broader enzyme blocker with more unpredictable effects on blood pressure.

🔬Pharmacokinetics — how your body processes it▾

When taken as an orally dissolving tablet placed on the tongue, selegiline is absorbed very rapidly — detectable in the bloodstream within 5 minutes, with peak levels reached in about 10–15 minutes. Because it's absorbed through the mouth's lining before reaching the stomach, it bypasses first-pass liver processing, leading to higher drug levels compared to a standard swallowed tablet. Food significantly reduces absorption, which is why you should avoid eating or drinking for 5 minutes before and after each dose.

Up to 85% of selegiline binds to proteins in the blood. It is metabolized in the liver (primarily by enzymes CYP2B6 and CYP3A4) into several breakdown products, including small amounts of l-methamphetamine and l-amphetamine metabolites. Steady-state blood levels are reached after about 8 days of daily use, and the effective half-life at steady state is around 10 hours.

📦How to store it▾

stored inside a clear child-resistant outer pouch and is packaged in a carton. Store at controlled room temperature, 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Store blister tablets in sachet pouch at all times.

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Selegiline — the kind of thing our pharmacy team would talk through with you at the counter.

Why am I taking selegiline if I'm already on levodopa? Isn't one medication enough? ▾
That's a really common question. Selegiline isn't meant to replace your levodopa — it's designed to make it work better. Over time, many people find their levodopa starts wearing off faster or becoming less consistent. Selegiline helps by slowing down the breakdown of dopamine in your brain, so the dopamine your levodopa creates sticks around longer. Think of it as a helper that makes your main medication more effective. It doesn't work on its own, though — it only helps when used alongside levodopa/carbidopa.
How do I take the dissolving tablet? It seems different from regular pills. ▾
It is a bit different! You peel back the blister pack — don't push the tablet through the foil — and with dry hands, gently take out the tablet and immediately place it on top of your tongue. It dissolves in seconds, no water needed. The important thing is to take it in the morning before breakfast, and don't eat or drink anything for 5 minutes before or after. Food reduces how much of the medication gets absorbed, so that timing window really matters.
Are there foods I need to avoid while taking selegiline? ▾
Great question — and yes, this is worth paying attention to. At higher-than-recommended doses, selegiline can react with tyramine (a natural substance in aged and fermented foods) and cause a dangerous spike in blood pressure. Foods like aged cheeses, cured meats, red wine, and certain fermented products are the main ones to be aware of. Even at the recommended dose, rare reactions have been reported. Never take more than your doctor prescribes, and let your doctor know if you regularly eat a lot of these foods so they can advise you specifically.
What medications can't I take with selegiline? I use a cough syrup sometimes. ▾
This is really important. Selegiline has some serious interactions. Many common cough syrups contain dextromethorphan — that's a big one to avoid with selegiline, as it can cause psychosis or very strange behavior. Opioid pain medicines like tramadol or codeine are also a hard no — the combination can be life-threatening. And some antidepressants, including SSRIs like fluoxetine or sertraline, can cause a dangerous condition called serotonin syndrome when combined with selegiline. Always check with your pharmacist before taking any new medication, supplement, or OTC product.
I've been feeling a little drowsy — is it safe for me to drive? ▾
Drowsiness is worth taking seriously with selegiline. The medication can cause some people to fall asleep suddenly during everyday activities — including driving — without feeling overly sleepy beforehand. Until you know how it affects you personally, be careful about driving or operating machinery. If you notice any unexpected drowsiness, talk to your doctor before getting behind the wheel. Your safety — and others' — really matters here.
Can I just stop taking selegiline if I decide I don't want it anymore? ▾
Please don't stop it abruptly without talking to your doctor first. Stopping selegiline suddenly can cause a reaction that includes high fever and confusion. Your doctor will guide you on how to safely taper or discontinue it if needed. Also, remember that many medications — like opioids or certain antidepressants — require a 14-day waiting period after stopping selegiline before you can safely start them. So always loop in your care team before making any changes.
Is Selegiline available over the counter? ▾
Selegiline is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
When was Selegiline first available? ▾
Selegiline has been available in the United States since at least 1989, based on FDA approval history (Drugs@FDA) and product marketing records.
Who makes Selegiline? ▾
Selegiline is supplied by 25 manufacturers listed in the FDA NDC Directory, including Apotex Corp., Viatris Specialty LLC, Marlex Pharmaceuticals, Inc..

How we combine label and product data

HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 14 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.

For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Bausch Health US, LLC is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
