How Eldepryl works (mechanism of action)
Selegiline belongs to the MAOI family. It works mainly by inhibiting an enzyme called monoamine oxidase (MAO), particularly the MAO-B subtype at usual therapeutic doses.
MAO-B normally breaks down brain chemicals such as dopamine. By inhibiting MAO-B, selegiline helps increase and prolong dopamine activity in the brain. Dopamine plays a key role in coordinating movement, so this effect may reduce symptoms of Parkinson’s disease.
Selegiline can also affect other neurotransmitter systems. This is one reason it may be considered for certain depressive symptoms under specialist direction. Because of the medicine’s MAOI activity, careful attention to food and medicine interactions is important (details below).
Pharmacokinetics (how the body handles it)
After you take selegiline, it is absorbed from the gastrointestinal tract and metabolised in the body. It is converted into metabolites that may also have biological activity. Key practical points include:
- Onset: Symptom improvement (especially in movement symptoms) can take time. Some effects may be noticed after regular use, while full benefit is often assessed over weeks.
- Metabolism: Selegiline is extensively metabolised in the liver to various compounds, including amphetamine-like metabolites in small amounts.
- Half-life: The parent drug and its metabolites have different durations of action, which influences dosing schedules and why consistent timing matters.
- Effect duration: Because it helps slow breakdown of dopamine, it may provide longer functional benefit rather than a short “pain-killer-like” effect.
Typical uses in Australia
Eldepryl (selegiline) is used for:
- Parkinson’s disease: often to improve symptoms, particularly to help manage motor fluctuations and to complement other Parkinson’s medicines.
- Certain depressive conditions (in selected cases): your clinician may consider it when other treatments are unsuitable or when it fits a specific plan.
Use depends on your individual diagnosis, symptom pattern, and other medicines you take.
Timing — when and how to take it
Many people take selegiline once daily and/or early in the day depending on the regimen. This helps reduce the chance of sleep disturbance.
- Take at the same time each day to maintain steady effect.
- Morning or early daytime is commonly preferred if it is activating or if you notice insomnia.
- Follow your dosing schedule carefully. Different strengths or treatment plans can vary.
If you miss a dose, don’t double up. Take the next dose at the usual time and contact your pharmacy or healthcare professional if you’re unsure.
Food interactions (and what to watch for)
Because selegiline is a MAOI, food interactions can matter. At usual doses where selegiline is more selective for MAO-B, the risk is generally lower than non-selective MAOIs, but precautions are still important—especially if your dose is higher, your medical team is adjusting treatment, or you notice symptoms after eating.
Tyramine and “cheese/aged foods”
MAOIs can interfere with the breakdown of tyramine (found in certain aged or fermented foods), which can raise blood pressure. This is sometimes discussed as the “cheese effect.”
Consider limiting or avoiding high-tyramine foods if advised by your clinician or if you have previously experienced reactions. Examples often highlighted include:
- Aged or ripened cheeses (e.g., parmesan, blue cheeses)
- Fermented or cured meats (e.g., some salami, fermented sausages)
- Yoghurts or foods with live cultures in large or unusual amounts (case-by-case)
- Overripe bananas and certain broad categories of aged/fermented foods
- Products made with yeast extracts or long-aged/fermented preparations
Alcohol-free and symptom-based approach
You may be advised to use a precautionary approach rather than strict avoidance of every listed item. If you choose a symptom-based approach, pay attention to warning signs after meals (see “Safety profile”).
If you have specific dietary questions, ask your pharmacist for guidance tailored to your dose and regimen.
Alcohol and medicine interactions
Alcohol
Alcohol can worsen dizziness, drowsiness, or low blood pressure and may impair judgement. When combined with medicines affecting neurotransmitters (including MAOIs), alcohol can sometimes increase side effects or reduce tolerability.
- Use caution and consider limiting alcohol.
- If you notice flushing, palpitations, headache, or marked dizziness after drinking, seek advice promptly.
Important medicine interactions
MAOIs can interact with many medicines. Some interactions can be severe. Below is a practical overview—this is not an exhaustive list, but it covers many common areas.
Serotonergic medicines (risk of serotonin syndrome)
Using selegiline with other medicines that increase serotonin may raise the risk of serotonin syndrome, a potentially serious condition.
- SSRIs (e.g., sertraline, fluoxetine)
- SNRIs (e.g., venlafaxine, duloxetine)
- Tricyclic antidepressants (e.g., amitriptyline)
- Some migraine medicines and other serotonergic agents
- Certain cough/cold products containing dextromethorphan (depending on ingredients)
A washout period may be required when switching between MAOIs and other antidepressants. Always follow the plan given by your clinician.
Sympathomimetics and some cold remedies (risk of blood pressure changes)
Selegiline may interact with medicines that affect adrenaline/noradrenaline activity. Particular caution is required with:
- Decongestants (including some nasal sprays and oral products)
- Certain stimulants or appetite suppressants
- Some asthma or respiratory medicines that have sympathomimetic effects
Other Parkinson’s medicines
Selegiline is commonly used with other Parkinson’s medications. Combination regimens can be effective, but side effects (such as dizziness, sleep changes, or movement-related problems) may be influenced by the overall plan.
Opioids and other pain medicines
Some opioid analgesics can carry interaction risks with MAOIs depending on the specific medicine. If you need pain relief, tell your pharmacist what you take so they can check safety.
Herbal and over-the-counter products
“Natural” doesn’t always mean safe with MAOIs. Avoid or seek advice before using:
- St John’s wort (may affect mood medicines and increase interaction risk)
- Supplements with stimulant effects
- Any product you are unsure about—ask your pharmacist
Indications — when clinicians may prescribe Eldepryl
While local guidelines and specialist decisions apply, selegiline is generally used for:
- Parkinson’s disease: as monotherapy in early-stage disease in some circumstances, and/or as add-on therapy with levodopa and/or other agents to improve motor symptoms and potentially reduce fluctuations.
- Depression (selected situations): in carefully selected patients under specialist direction.
Dosing — typical schedules and practical notes
The exact dose depends on your condition, age, liver function, and other medicines. Always take your medicine as directed on your Australian pharmacy label.
Typical dosing patterns
- Parkinson’s disease: selegiline is commonly taken , though some regimens may involve different timing based on the tablet strength and clinical plan.
- Depression (selected cases): dosing schedules vary and may require careful monitoring for mood changes and side effects.
How to take it
- Swallow tablets with water.
- Try to take it at a consistent time each day.
- If you are sensitive to sleep disruption, prioritise morning dosing (unless your clinician advises otherwise).
What to do if you start other medicines
Before starting any new medicine (including antibiotics, anti-nausea medicines, or cold/flu preparations), check the interaction potential with your pharmacist. This is especially important for antidepressants, decongestants, and serotonergic migraine medicines.
Safety profile — what to know before and during treatment
Common side effects
- Dizziness or light-headedness
- Nausea or stomach upset
- Headache
- Sleep disturbance (insomnia) in some people, particularly if taken late
- Dry mouth
Serious but less common risks
Seek urgent medical help if you experience symptoms that may indicate a serious reaction.
- Serotonin syndrome: agitation, confusion, sweating, fever, fast heart rate, shaking/tremor, diarrhoea, or muscle stiffness—especially if new serotonergic medicines are added.
- Hypertensive crisis (tyramine-related): severe headache, chest pain, significant blood pressure rise, or severe palpitations—particularly after high-tyramine foods or interacting medicines.
- Fainting or severe dizziness (possible blood pressure effects).
Warning signs to watch for
- New or worsening severe headache
- Flushing, sweating, or palpitations after meals or alcohol
- Marked increase in anxiety or restlessness
- Confusion, fever, or unusual muscle stiffness
Who should be extra careful
Discuss risk and monitoring with your healthcare professional if you have:
- Uncontrolled high blood pressure or significant cardiovascular disease
- History of adverse reaction to MAOIs
- Significant liver problems
- Multiple interacting medicines (especially antidepressants and decongestants)
- Older age or a tendency to dizziness/falls
Practical use tips for everyday life
- Keep a medication list: carry (or keep on your phone) a list of all medicines and supplements you take, including cold/flu products.
- Check labels on decongestants and combination cold medicines—some ingredients may be problematic.
- Plan for “switching” antidepressants: timing and washout matters. If you’re changing mood medicines, coordinate closely with your clinician.
- Monitor sleep: if you notice insomnia, move the dose earlier (if allowed by your plan) and speak with your pharmacist.
- Be consistent with meals: avoid experimenting with large quantities of aged/fermented foods, particularly early in treatment or after dose changes.
- Hydrate and stand up slowly: dizziness can be reduced by slow position changes and staying well hydrated.
Alternative options
“Alternative” depends on whether the goal is Parkinson’s symptom control or management of mood symptoms. Here are broad categories your clinician may consider.
For Parkinson’s disease
- Levodopa/carbidopa (for motor symptom control)
- Dopamine agonists
- COMT inhibitors (reduce breakdown of levodopa)
- Other MAO-B inhibitors (e.g., rasagiline) may be considered in some patients
- Non-drug strategies: physiotherapy, exercise programs, occupational therapy
For depressive symptoms
- SSRIs or SNRIs
- Tricyclic antidepressants in selected cases
- Other augmentation strategies depending on diagnosis
- Psychological therapies (e.g., CBT) often complement medication
Your clinician will weigh benefits versus interaction risk and your personal medical history.
Australia market and legal context (overview)
In Australia, medicines are regulated through the Therapeutic Goods Administration (TGA). Selegiline products like Eldepryl are available via the Australian medicines supply chain. Classification (e.g., whether it is prescription-only or has specific dispensing restrictions) is determined by regulators and depends on the formulation and strength.
If you’re purchasing from an online pharmacy, reputable providers will verify eligibility and ensure appropriate dispensing procedures are followed. Always use Australian-licensed supply channels.
Recent guidance and monitoring considerations
Guidance for MAOIs can evolve based on safety monitoring, drug-interaction evidence, and updates to prescribing information. Practical points that remain consistent include:
- Drug interaction awareness: clinicians and pharmacists emphasise checking serotonergic and decongestant combinations.
- Patient education: clear advice about tyramine-containing foods and symptom recognition.
- Ongoing review: monitoring benefits and side effects, especially after dose changes or when adding other medicines.
If you have been on Eldepryl for a while, it’s still worth reviewing your current medicine list with your pharmacist annually (or whenever you start or stop a medication).
