Eldepryl (Selegiline) — Patient-Friendly Information (Australia)

Eldepryl is a medicine that contains selegiline. It is used in the treatment of certain conditions of the brain and nervous system, most commonly Parkinson’s disease. Eldepryl works by affecting brain chemical pathways involved in movement and nerve signalling.

This guide is written for people in Australia and explains how Eldepryl works, what it’s used for, how to take it, key safety considerations, and what to discuss with your healthcare professional.

Basic product information

• Active ingredient: Selegiline
• Brand name: Eldepryl
• Typical dosage forms (commonly encountered): Tablets (varies by formulation and local supply)
• Medicine class: Monoamine oxidase (MAO) inhibitor (selective MAO-B inhibitor)
• Where it fits clinically: Often used for Parkinson’s disease, usually as part of a treatment plan

Note: Product strength and formulation details can vary by brand and market availability. Always check the packaging or product label for the exact strength and instructions.

How Eldepryl works (mechanism of action)

Selegiline is a selective inhibitor of monoamine oxidase type B (MAO-B). In the brain, MAO-B is involved in breaking down dopamine and related compounds.

By inhibiting MAO-B, selegiline:

• Reduces dopamine breakdown in the brain
• Helps maintain dopamine levels for longer periods
• May improve motor symptoms such as slowness of movement (bradykinesia), rigidity, and tremor, depending on the individual and overall regimen

Selegiline is sometimes described as having an effect that can extend the benefit of dopamine-related therapies, particularly in Parkinson’s disease.

Pharmacokinetics (how your body handles selegiline)

Pharmacokinetics explains what happens to a drug in the body: absorption, distribution, metabolism, and elimination.

• Absorption: Selegiline is absorbed after oral dosing. Onset of effects depends on the formulation and individual response.
• Distribution: It reaches the central nervous system to influence brain pathways.
• Metabolism: Selegiline is primarily metabolised in the liver to active and inactive metabolites.
• Elimination: Metabolites are excreted mainly via urine (with some excretion via other routes depending on metabolism).
• Duration of action: The clinical effect often persists beyond a single dose because MAO-B inhibition can last, but the exact duration varies among individuals.

If you have liver problems, reduced kidney function, or take multiple medicines, your clinician may adjust the plan to match your risk profile.

Typical uses and indications

The most well-known indication for selegiline is:

• Parkinson’s disease — to help reduce symptoms and improve motor function, often used alone in early stages or as an add-on to levodopa/other treatments depending on the person’s needs.

In practice, the exact role of Eldepryl in a Parkinson’s treatment plan varies based on age, symptom pattern, disease stage, and other medicines used.

When to take it (timing and dose schedule)

Many people are advised to take Eldepryl at a time that fits their daily routine and minimises side effects such as insomnia.

General timing guidance:

• Often taken in the morning to reduce the chance of sleep disturbance.
• Avoid late-day dosing unless your clinician instructs otherwise.

Important: Follow the exact dosing instructions on your prescription label (or the label on your product supply). Different formulations and strengths may have different instructions.

Dosing (general information)

Dose schedules differ between individuals and may depend on formulation. The following provides general information only.

• Start low, then adjust: Clinicians commonly start with a conservative dose and adjust according to response and tolerability.
• Adherence matters: Consistent daily use is typically important for sustained benefit.
• Do not change your dose suddenly: If you need to stop or alter Eldepryl, discuss this with your healthcare professional.

Practical tip: If you miss a dose, take it as instructed by your clinician/pharmacist or the product information. In general, if it’s near the next dose time, you may be advised to skip—do not double unless specifically told.

Food interactions (what to know)

Selegiline is MAO-B selective, which generally reduces (but does not always completely eliminate) food restrictions compared with older non-selective MAO inhibitors.

Still, interactions can occur depending on:

• the dose of selegiline
• your individual sensitivity
• co-administered medicines

Typical dietary considerations:

• Tyramine-containing foods: With MAO inhibitors, large amounts of tyramine can potentially trigger symptoms such as headache and blood pressure changes. With MAO-B selective therapy, severe tyramine reactions are less common, but caution is still wise—especially at higher doses or if other MAO-influencing medicines are taken.
• Food safety: Avoid very aged, fermented, or improperly stored foods if advised by your clinician.

Advice to follow: If you have been given specific dietary instructions for MAO-related medicines, follow those instructions carefully.

Alcohol and medicine interactions

Alcohol

Alcohol may worsen side effects such as dizziness, sleep disturbance, and impaired coordination. Because Parkinson’s disease itself can affect balance and reaction times, combining alcohol with Eldepryl may increase risk of falls.

• Recommendation: Keep alcohol intake modest, and monitor how you feel.
• Seek advice: If alcohol triggers dizziness, worsening tremor, or changes in mood, discuss this with your clinician.

Medicine interactions

Eldepryl can interact with medicines that affect serotonin, noradrenaline, dopamine, or blood pressure. Some interactions may be serious.

Common interaction categories to discuss:

• Antidepressants (especially SSRIs, SNRIs, tricyclic antidepressants): Combining serotonergic medicines with MAO inhibitors can increase the risk of a serious condition called serotonin syndrome (symptoms may include agitation, fever, sweating, tremor, diarrhoea, and confusion).
• Other MAO inhibitors: Combining with other MAO inhibitors increases risk of adverse reactions and is typically avoided.
• Some migraine medicines (e.g., certain triptans): May increase the risk of serotonin-related reactions.
• Cough/cold medicines and stimulants: Some decongestants or “energy” products may affect blood pressure and interact with MAO-related pathways.
• Dopamine-related medicines (e.g., levodopa, dopamine agonists): Often used together in Parkinson’s, but the combination should be managed carefully to balance benefits and side effects such as dyskinesia (abnormal involuntary movements) or hallucinations.
• Blood pressure medicines: Potential for additive effects leading to dizziness or changes in blood pressure, especially when standing (orthostatic hypotension).
• Pethidine (meperidine) and some opioid medicines: Certain opioids have well-known MAO-related interaction risks.
• Linezolid (an antibiotic) and other monoamine oxidase–affecting agents: These may be incompatible or require specialist advice.

Always check before starting new medicines: Tell your pharmacist or doctor about all medicines you use, including herbal supplements (for example, St John’s wort), over-the-counter products, and any “natural” sleep or mood remedies.

Safety profile and side effects

Most medicines can cause side effects. Many are manageable, and benefits often outweigh risks for appropriately selected patients. However, you should know what to watch for.

Common or potential side effects

• Nausea or stomach discomfort
• Dizziness, especially when standing quickly
• Dry mouth
• Headache
• Insomnia or sleep disturbance (more likely if taken late in the day)
• Reduced appetite

Serious but uncommon warning signs

Seek urgent medical help if you experience any of the following:

• Symptoms of serotonin syndrome: agitation, confusion, fever, sweating, diarrhoea, fast heartbeat, severe tremor, muscle stiffness.
• Severe allergic reaction: swelling of the face/lips, wheezing, rash, or difficulty breathing.
• Significant blood pressure symptoms: severe headache, chest pain, fainting, or severe dizziness.
• Hallucinations, confusion, or extreme agitation: especially if you also take other Parkinson’s medicines.
• New or worsening thoughts of self-harm: if mood changes occur, contact a healthcare professional promptly.

Who should use extra caution?

• People with liver disease
• People with a history of low blood pressure or frequent fainting
• People taking multiple medications that affect serotonin, blood pressure, or the nervous system
• Older adults who are more prone to dizziness and falls

Practical use tips

• Take at the same time each day to maintain steady effect.
• Take earlier in the day if sleep problems occur.
• Maintain hydration and stand up slowly to reduce dizziness.
• Keep a medication list (including OTC and supplements) and show it to your pharmacist.
• Be cautious with new products (cold/flu remedies, herbal supplements, weight-loss or stimulant products).
• Monitor symptoms: keep track of improvements (slowness/tremor) and side effects (sleep, dizziness, hallucinations).

If you experience troublesome side effects: do not stop suddenly without advice. Contact your healthcare professional to discuss dose adjustment or alternatives.

Alternative options

Depending on the condition being treated, there are several alternative or complementary treatment options. Your doctor chooses options based on Parkinson’s disease stage, your symptoms, and other health conditions.

For Parkinson’s disease, alternatives may include:

• Levodopa/carbidopa combinations
• Dopamine agonists
• COMT inhibitors (often used to extend levodopa effects)
• MAO-B inhibitors other than selegiline (e.g., depending on availability and suitability)
• Physiotherapy and occupational therapy for movement and balance support
• Other medication classes depending on specific symptoms (tremor, stiffness, freezing, non-motor symptoms)

Your best alternative depends on how you respond to treatment and which medicines you already use.
