Eldepryl (Selegiline) — Patient Information (Australia)

Eldepryl is a medicine containing selegiline, used mainly in the treatment of certain forms of Parkinson’s disease. Selegiline helps improve symptoms by affecting brain chemicals involved in movement. This page is written to be patient-friendly and explains how Eldepryl works, how it is taken, key safety considerations, interactions, and practical tips for everyday use in Australia.

Always follow the instructions provided by your healthcare professional and read the Consumer Medicine Information (CMI) supplied with your medicine. If you are unsure about timing, dose, or interactions, ask your pharmacist.

Quick Product Facts

How Eldepryl Works (Mechanism of Action)

Selegiline belongs to a group of medicines called MAO inhibitors. Specifically, it selectively inhibits monoamine oxidase type B (MAO-B) at typical therapeutic doses. MAO-B is an enzyme in the brain responsible for breaking down certain neurotransmitters, including dopamine.

By inhibiting MAO-B, Eldepryl can help reduce dopamine breakdown, which may improve or stabilise movement-related symptoms in Parkinson’s disease. In many treatment plans, it is used alongside other Parkinson’s medicines (for example, levodopa or dopamine agonists), with the goal of improving symptom control over the day.

Pharmacokinetics (What the Body Does to the Medicine)

Understanding pharmacokinetics can help explain why timing matters and why some interactions occur. Key points include:

• Absorption: Selegiline is absorbed after oral dosing. Food may influence the rate of absorption depending on the specific product formulation.
• Distribution: Selegiline acts in the central nervous system; it crosses into the brain where MAO-B inhibition occurs.
• Metabolism: Selegiline is metabolised mainly in the liver. It is converted into metabolites, including amphetamine-like and other breakdown products (the clinical significance varies by dose and individual response).
• Excretion: Metabolites are eliminated primarily through the kidneys (urine) and, to a lesser extent, via other routes.
• Half-life and duration of effect: The “duration” of symptom benefit may not match the exact drug half-life because MAO-B inhibition affects neurotransmitter metabolism and downstream pathways. Effects can last longer than you might expect from plasma levels alone.

Your dosing schedule is designed to provide benefit while minimising side effects. Do not change your dose without medical advice.

Typical Use and Indications

Eldepryl is used for Parkinson’s disease. Clinicians may prescribe it:

• To improve motor symptoms and overall function.
• As an adjunct to levodopa or other Parkinson’s medicines to help reduce periods when symptoms return (commonly described as “off” time).
• In some people, as part of an early-stage strategy to slow symptom progression and improve day-to-day control.

If you have been prescribed Eldepryl for a specific reason, use it exactly as directed. Treatment may be adjusted based on your response, other medicines, and tolerability.

When to Take Eldepryl (Timing and Practical Routine)

Timing is important because side effects like insomnia or restlessness can occur. In many treatment regimens, selegiline is taken earlier in the day.

General timing tips

• Take earlier in the day if your prescriber or CMI advises it, especially if you notice sleep disturbance.
• Be consistent: try to take each dose at similar times daily.
• Use reminders (pill box, phone alarm) to avoid missed doses.
• If you miss a dose, take it when you remember unless it is close to the next scheduled dose. Do not double dose unless your healthcare professional advises otherwise.

Food Interactions (Eating with Eldepryl)

Food can sometimes affect the speed of absorption of medicines. For selegiline, specific food effects depend on the formulation and individual response.

• Follow the directions on your CMI for whether to take with food or on an empty stomach.
• If you have stomach upset, taking the medicine with a small meal may be suggested by your pharmacist (unless the CMI specifies otherwise).
• If you are also taking medicines for nausea or reflux, ask whether timing should be adjusted.

Alcohol and Medicine Interactions

Alcohol

Alcohol may worsen symptoms or increase side effects such as dizziness, drowsiness, or blood pressure changes. Because Parkinson’s disease itself can affect balance and alertness, it’s usually safest to:

• Limit alcohol and avoid binge drinking.
• Monitor for dizziness, light-headedness, or sleepiness.
• Discuss with your healthcare professional if you drink regularly or have liver issues.

Important medicine interactions

Some medicines can interact with Eldepryl in serious ways. The most important category includes medicines that increase serotonin and certain antidepressants and pain medicines.

Seek urgent medical advice if you experience symptoms that could suggest a serious interaction, such as:

• High fever, severe agitation, confusion
• Muscle stiffness, tremor, fast heart rate
• Severe diarrhoea and sweating

Common interaction categories to discuss with your pharmacist

• Antidepressants (especially those affecting serotonin) such as SSRIs, SNRIs, tricyclic antidepressants, and others.
• Serotonin-related medicines and some migraine medicines (for example, triptans).
• Opioid pain medicines that have serotonergic effects (some opioids can interact; specific agents matter).
• Other MAO inhibitors (avoid unless specifically directed).
• Decongestants or cold/flu medicines containing sympathomimetics, which can affect blood pressure and heart rate.
• Stimulants and some cough/cold products.
• Levodopa and other Parkinson’s medicines: often used together, but the combination may require monitoring and dose adjustments.

Always provide a list of your medicines to your pharmacist, including over-the-counter products, herbal supplements, and vitamins. If you use a “natural” product, confirm it is safe—some herbal products may affect neurotransmitters or liver enzymes.

Dosing (How to Take Eldepryl)

Dosing should be individualised based on your condition, response, and other medicines. The following information is general and may not match your exact prescription instructions. Please follow your CMI and clinician’s directions.

Typical approach

• Start low and adjust: many regimens begin with a lower dose and adjust gradually.
• Once daily vs multiple times daily: depending on formulation and your plan, dosing may be once daily or divided doses.
• Monitor effect: symptom response and side effects guide further adjustments.

Do not exceed the prescribed dose

Higher doses increase the chance of adverse effects and may reduce selectivity of MAO inhibition, potentially increasing dietary/amine-related concerns and drug interaction risks. If you feel the medicine is not working or side effects are bothersome, contact your healthcare professional rather than changing the dose yourself.

Safety Profile (Common and Serious Side Effects)

Like all medicines, Eldepryl can cause side effects. Some people experience few or mild effects; others may experience more. Many side effects improve as your body adjusts or with dose changes.

Common side effects

• Insomnia or difficulty sleeping
• Dizziness or light-headedness
• Nausea
• Dry mouth
• Headache
• Loss of appetite (less commonly)
• Agitation or restlessness

Less common but important effects to watch for

• Blood pressure changes (particularly when standing up), which can increase fall risk.
• Hallucinations or confusion, especially in older adults or those on multiple neuroactive medicines.
• New or worsening dyskinesia if used with levodopa (in some people).

Serious reactions (seek urgent care)

• Signs of a serotonin-related reaction (fever, agitation, severe diarrhoea, sweating, muscle stiffness).
• Chest pain, severe shortness of breath, or fainting.
• Severe allergic symptoms such as swelling of face/lips, rash, or breathing difficulty.

Practical Use Tips for Everyday Life

• Track your symptoms: write down “on” and “off” periods (when mobility is better or worse). This helps your clinician optimise dosing.
• Plan around sleep: if insomnia occurs, discuss changing the timing with your pharmacist or prescriber.
• Stand up slowly: to reduce dizziness and fall risk.
• Keep a medication list: include prescriptions, over-the-counter products, and supplements—bring it to appointments.
• Be cautious with new medications: before starting cold/flu remedies, pain medicines, or antidepressants, check with your pharmacist.
• Don’t stop suddenly: unless advised. Stopping may worsen symptoms.

Dietary Considerations: Amines and “Tyramine” Foods

Selegiline is often described as selectively inhibiting MAO-B at typical doses, which may reduce—though not completely eliminate—dietary tyramine concerns. However, dietary guidance can vary based on dose and formulation. To be safe:

• Follow your CMI for any specific food restrictions.
• If your clinician has advised avoiding certain foods, adhere to that advice closely.
• If you experience severe headache, palpitations, or a sudden feeling of unwell after certain foods, seek medical advice promptly.

If you have questions about foods (for example, aged cheeses, cured meats, or fermented products), ask your pharmacist for tailored advice.

Alternative Options (Other Treatments for Parkinson’s Disease)

Treatment for Parkinson’s disease is individualised. Depending on your stage of disease and other medicines, alternatives to selegiline may include:

• Levodopa/carbidopa (a mainstay therapy)
• Dopamine agonists (for example, pramipexole or ropinirole)
• Other MAO-B inhibitors (such as rasagiline; availability and suitability vary)
• COMT inhibitors (used with levodopa in some cases)
• Amantadine (sometimes used for specific symptoms)
• Physiotherapy and supportive care to improve mobility and reduce fall risk

Your healthcare professional may recommend switching based on symptom control, side effects, or interactions with other medications.
