Eldepryl (Selegiline) – Patient-Friendly Guide (Australia)

Eldepryl is a brand of selegiline, a medicine used in certain neurological conditions. This page explains how selegiline works, how it is typically used, what to expect, and key safety information. It is written to be clear and practical for patients and carers in Australia.

Important: Always follow the advice of your healthcare professional and the directions on your medicine label. If you are unsure about how to take Eldepryl, ask your pharmacist.

Basic product information

How Eldepryl (Selegiline) works (mechanism of action)

Selegiline belongs to a group of medicines called monoamine oxidase inhibitors (MAOIs). It primarily acts as an MAO-B inhibitor, which means it helps reduce the breakdown of specific brain chemicals.

• MAO-B inhibition: MAO-B is an enzyme that breaks down dopamine in the brain. By inhibiting MAO-B, selegiline can help maintain higher dopamine levels.
• Symptom support in Parkinson’s disease: Increased availability of dopamine-related signalling can help with movement symptoms.
• Depression-related actions (where relevant): MAOIs can increase the availability of monoamine neurotransmitters (e.g., serotonin, noradrenaline, dopamine) depending on the pattern of inhibition and dose.

In plain terms: Eldepryl may help the brain use or retain certain neurotransmitters longer, which can improve symptoms in appropriate conditions.

Pharmacokinetics (how the body handles selegiline)

Pharmacokinetics describes what happens from the time you take a dose until it leaves your body. While exact results can vary between individuals, key points include:

• Absorption: Selegiline is absorbed after oral dosing.
• Metabolism: The body metabolises selegiline primarily in the liver. Active metabolites can be formed, which may contribute to its overall effects.
• Distribution: Selegiline and metabolites reach the brain where MAO-B inhibition occurs.
• Elimination: Metabolites are eliminated mainly via the kidneys (urine).
• Timing of effect: Some benefits may become noticeable over days to weeks, while dose adjustments for symptom control may take longer.

Because metabolism involves the liver, liver function and certain interacting medicines can affect how selegiline behaves in your body.

Typical use in Australia

Eldepryl (selegiline) is most commonly associated with:

• Parkinson’s disease: Often used as part of long-term management to help reduce “wearing off” or to improve symptoms in selected patients. It may be used alone or alongside other Parkinson’s medicines depending on your clinical plan.
• Depression: In some clinical settings, MAO-B inhibitors may be used for depression-related indications. Your clinician will consider suitability carefully, especially when other medicines affecting serotonin or mood are involved.

Your healthcare professional will determine whether Eldepryl is appropriate for you based on your diagnosis, current medicines, and medical history.

When to take Eldepryl (timing tips)

Selegiline can be stimulating for some people. For this reason, it is commonly taken in the morning or at times that match the prescribed regimen.

• Morning dosing: Many people take selegiline in the early part of the day to reduce the risk of sleep disruption.
• Consistency matters: Try to take your dose at the same time each day.
• If you miss a dose: Take it when you remember unless it is close to the next dose time. Do not double up. If you are unsure, ask your pharmacist.

Practical tip: Set a daily alarm or link dosing to a routine (e.g., breakfast). This helps reduce missed doses.

Food interactions: what to know

MAOIs are best known for interactions with certain foods containing tyramine (a “cheese effect”). However, the risk level depends on dose and the selectivity for MAO-B.

• Tyramine concerns: At higher (less selective) MAOI activity, tyramine-rich foods can trigger dangerous blood pressure changes.
• With MAO-B selective dosing: The risk is generally lower compared with older non-selective MAOIs, but caution is still advised, especially if your dose is higher than usual or if your doctor changes your regimen.
• General safe practice: Avoid very tyramine-rich or improperly stored foods. If in doubt, speak with your pharmacist.

Examples of foods commonly flagged with MAOIs:

• Overripe or improperly stored foods
• Fermented or aged foods (e.g., some aged cheeses)
• Tap/draft or improperly stored fermented beverages

Bottom line: You may not need strict dietary restriction at all doses, but it’s important to follow personalised advice from your clinician or pharmacist and to be cautious with tyramine-containing foods.

Alcohol interactions with Eldepryl (Selegiline)

Alcohol can affect mood, coordination, and blood pressure. When combined with medicines that influence brain neurotransmitters, alcohol may increase the risk of:

• Dizziness or sedation (even if selegiline is not sedating itself)
• Falls due to impaired balance
• Blood pressure changes in some people
• Worsened depression symptoms (for those taking it for mood-related indications)

Practical approach: If you choose to drink, start with small amounts and observe how you feel. Avoid binge drinking. If you have concerns (e.g., falls, low blood pressure, liver issues, or mood changes), discuss alcohol use with your pharmacist or doctor.

Medicine interactions: important warnings

Eldepryl can interact with a range of medications. Some interactions are serious and may require careful monitoring or avoiding the combination altogether.

Always tell your pharmacist/doctor about all medicines you take, including:

• Over-the-counter medicines
• Herbal products (e.g., St John’s wort)
• Cold and flu remedies
• Weight-loss products
• Substances or recreational drugs

1) Serotonin-related medicines (risk of serotonin syndrome)

Combining MAOIs with certain drugs that increase serotonin can increase the risk of serotonin syndrome, which may be life-threatening.

Examples include (not exhaustive):

• Some antidepressants (SSRIs, SNRIs, tricyclics and others)
• Other MAOIs
• Some migraine medicines
• Some opioid analgesics and cough medicines (depending on the specific active ingredient)

Warning signs of serotonin syndrome can include agitation, confusion, sweating, fever, tremor, diarrhoea, and muscle stiffness. Seek urgent medical help if symptoms occur.

2) Sympathomimetic drugs (blood pressure effects)

Medicines that affect adrenaline/noradrenaline pathways can increase the risk of blood pressure changes. Examples may include:

• Some decongestants (especially those containing stimulatory ingredients)
• Certain asthma or stimulant medicines

3) Other Parkinson’s or neuroactive medicines

Selegiline is often used with other Parkinson’s medications. Your clinician may adjust doses to reduce side effects such as:

• Low blood pressure when standing
• Hallucinations or confusion (more likely in some people)
• Dyskinesia (in some treatment combinations)

4) CYP metabolism and liver considerations

Because selegiline is metabolised in the body, other medicines that affect liver enzymes can change selegiline levels. This can affect both effectiveness and side effect risk.

Action step: Keep an up-to-date list of your medicines and review it with your pharmacist whenever you start or stop something new.

Indications: when Eldepryl is used

In clinical practice, Eldepryl (selegiline) is used for conditions such as:

• Parkinson’s disease – to help manage motor symptoms and support dopamine-related pathways.
• Some forms of depression – in particular clinical contexts, where careful selection and interaction checking are essential.

Exact indications and suitability depend on your diagnosis and local clinical guidance. Your healthcare professional can confirm whether it is appropriate for your specific situation.

Dosing: what “typical” may look like

Dosing must be individualised. Your prescribed regimen depends on your condition, age, overall health, and interacting medicines.

General dosing approach:

• Start low, adjust gradually: Many medicines in this class begin with a conservative dose to assess tolerance.
• Morning preference: Because it can affect sleep, dosing is commonly scheduled earlier in the day.
• Follow the label instructions: Do not change the dose or stop suddenly without medical advice.

Important: Dosing details can vary by product strength and patient factors. For the most accurate dosing instructions, refer to your medication label or ask your pharmacist.

Safety profile: common and serious side effects

Most people tolerate selegiline well when it is used appropriately. However, it can cause side effects in some individuals.

Common side effects

• Dizziness or light-headedness
• Nausea
• Dry mouth
• Headache
• Sleep disturbance (insomnia) in some people
• Changes in appetite

Less common but important side effects

• Hallucinations or confusion (more likely in older adults or when combined with other neuroactive medicines)
• Low blood pressure when standing
• Rash or allergic-type reactions

Seek urgent medical help if you experience

• Signs of serotonin syndrome: agitation, fever, sweating, tremor, diarrhoea, muscle stiffness, confusion
• Severe headache with vision changes, chest pain, or sudden severe blood pressure symptoms
• Fainting, severe dizziness, or signs of stroke
• Allergic reaction: swelling of face/lips, trouble breathing, widespread rash

Who needs extra caution?

• People with liver disease
• Older adults, particularly if prone to falls or confusion
• People taking multiple interacting medicines
• People with a history of mania or bipolar disorder (mood changes may occur with some antidepressant strategies)

Practical use tips (how to get the most from treatment)

• Keep a daily routine: Take your dose at the same time each day.
• Monitor blood pressure symptoms: If you feel faint when standing, rise slowly and inform your clinician.
• Track benefits and side effects: Note changes in mobility, mood, sleep, dizziness, or hallucinations.
• Avoid “double start” of new medicines: Ask before starting any new prescription or over-the-counter medicine, especially cold/flu products and antidepressants.
• Be cautious with herbal products: Some products can significantly affect serotonin or drug metabolism.
• Don’t stop abruptly: Stopping suddenly may worsen symptoms or destabilise mood in some people.

Alternative options (discuss with your clinician)

Alternative treatments depend on the condition being managed. Examples of options often discussed include:

• Parkinson’s disease: Other dopaminergic strategies (e.g., levodopa-containing treatments, dopamine agonists, COMT inhibitors, and other MAO-B inhibitors depending on suitability).
• Depression: Other antidepressant classes may be considered based on your history, symptoms, and interaction risk.

Why alternatives matter: If you cannot safely take selegiline due to medicine interactions, blood pressure concerns, or side effects, your healthcare professional can recommend safer options for your specific circumstances.
