Eldepryl (Selegiline) – Patient-Friendly Guide

Eldepryl is the brand name for selegiline, a medicine used mainly in the management of certain neurologic conditions. This guide is designed to help you understand how Eldepryl works, how it is typically used, what to expect, and the key safety considerations—especially interactions with food, alcohol, and other medicines.

In Australia, Eldepryl (selegiline) is regulated as a medicines product and availability, indications, and brand presentation can vary. Always follow the directions provided by your healthcare professional and the medication label.

Quick Product Overview

What Is Eldepryl?

Eldepryl contains selegiline, a medicine belonging to the group called monoamine oxidase (MAO) inhibitors. Selegiline is best known for its role in neurology, particularly as a treatment option in Parkinson’s disease.

Selegiline is often described as a selective MAO-B inhibitor. By acting primarily on MAO-B (an enzyme that breaks down certain brain chemicals), it can increase availability of dopamine in the brain.

Mechanism of Action (How It Works)

The brain uses dopamine for movement control. Dopamine is broken down by enzymes, including monoamine oxidase (MAO). Selegiline inhibits MAO-B, which is responsible for breaking down dopamine in certain brain pathways.

• MAO-B inhibition: Helps slow dopamine breakdown.
• Increased dopaminergic activity: May improve symptoms such as stiffness, slowness, tremor, and reduced mobility.
• Add-on benefits: In some treatment plans, selegiline may complement levodopa or other Parkinson’s medicines.

The effect is not immediate in the way some “as-needed” medicines work. Many patients notice improvement gradually as the medicine builds steady effects.

Pharmacokinetics (Absorption, Distribution, Metabolism, Excretion)

“Pharmacokinetics” describes what the body does to the medicine. While individual factors vary, the following provides a general overview:

• Absorption: Selegiline is absorbed after oral dosing.
• Metabolism: Selegiline is metabolised primarily in the liver. It may be transformed into metabolites that can contribute to activity.
• Distribution: It crosses into the central nervous system to affect brain MAO-B.
• Elimination: Metabolites are eliminated largely via urine and/or other routes depending on metabolic pathways.

Because selegiline is metabolised by the liver, liver health and interactions with other medicines can influence how safely and effectively it works. Inform your healthcare professional about liver disease or any abnormal liver function tests.

Typical Uses (Indications)

Selegiline is most commonly used for:

• Parkinson’s disease: As monotherapy in early disease and/or as an add-on in later stages (commonly with other Parkinson’s treatments such as levodopa).

The exact indication, choice of combination, and duration should be tailored to the individual. Your treating clinician may also consider selegiline in specific circumstances where the potential benefits fit your overall treatment plan.

Dosing & Timing

Dosing depends on the condition being treated, your response, your overall health, and the specific product strength and formulation. The information below is general.

How to take Eldepryl

• Take the medicine at the times directed.
• If once daily, it is commonly taken in the morning to reduce the risk of insomnia (difficulty sleeping).
• If twice daily, doses are often spaced across the day (for example, morning and mid-day rather than late evening).

Typical adult dosing (general reference)

Common regimens in clinical practice may include once-daily or twice-daily dosing. The exact dose for you should follow your healthcare professional’s instructions and the product label.

If you miss a dose: Take it when you remember unless it’s close to the next dose. Do not take a double dose to make up for missed doses.

Do not stop suddenly without medical advice. Stopping can worsen symptoms or destabilise control.

Food Interactions (Tyramine & Mealtimes)

MAO inhibitors can, in some cases, be associated with dietary interactions involving tyramine, a substance found in certain foods (especially fermented or aged foods).

What to know for selegiline

• At typical doses: Dietary restrictions may be less strict than with older non-selective MAO inhibitors.
• Higher doses or specific circumstances: The risk of tyramine-related reactions may increase.

Practical advice about food

To reduce risk:

• Be cautious with aged or fermented foods if you are advised to do so.
• Discuss diet with your clinician if you have a history of high blood pressure or if you are on other interacting medicines.
• If you notice symptoms such as severe headache, flushing, or palpitations after certain foods, seek advice promptly.

Your healthcare professional may provide specific dietary guidance based on your dose and personal risk factors.

Alcohol Interactions

Alcohol may increase the chance of side effects such as:

• Dizziness and light-headedness
• Sleep disturbances
• Low blood pressure (especially when rising)
• Impaired coordination

Because selegiline affects brain chemistry and may interact with other medications, it is generally recommended to avoid alcohol unless your clinician has advised it is acceptable for you.

Medicine Interactions (Important)

Many medicines can interact with selegiline, sometimes leading to serious reactions. It’s essential to provide your healthcare provider and pharmacist with a complete list of:

• All prescription and non-prescription medicines
• Herbal supplements (e.g., St John’s wort)
• Vitamins and “natural” products
• Recent medication changes

High-risk interaction categories

The following are examples of medicine groups that may require extra caution. Your clinician will decide whether to avoid, pause, or use alternative treatment.

• Antidepressants: Some antidepressants can increase interaction risk with MAO inhibitors, including serotonin-related toxicity. Examples include SSRIs, SNRIs, tricyclic antidepressants, and other serotonergic agents.
• Other MAO inhibitors: Combining with another MAO inhibitor is usually avoided.
• Opioid pain medicines: Certain opioids may raise risk of adverse interactions depending on the specific drug.
• Sympathomimetic drugs: Medicines that raise adrenaline activity (e.g., certain decongestants) may increase blood pressure or cause palpitations.
• Stimulants and some cough/cold products: Some over-the-counter products contain ingredients that could interact.

Serotonin-related risk

Some interactions can lead to a serious condition sometimes associated with excess serotonin activity. Seek urgent medical help if you develop:

• Agitation, confusion
• Fever or sweating
• Fast heartbeat, high blood pressure
• Shaking, muscle stiffness, or severe diarrhoea

Tell your pharmacist before starting anything new

Even common products such as cold and flu remedies may contain ingredients that can interact. Ask before using new medicines.
