How Eldepryl (Selegiline) Works (Mechanism of Action)
Selegiline is an MAO-B inhibitor. Monoamine oxidase (MAO) is an enzyme family that helps break down certain chemical messengers in the brain. Inhibiting MAO-B can reduce the breakdown of dopamine, a neurotransmitter involved in movement and motivation.
By enhancing dopamine availability, selegiline may help improve symptoms related to Parkinson’s disease, such as slowness of movement and rigidity. Selegiline may also contribute to effects on mood in some contexts, due to its impact on monoamine systems.
Why MAO-B inhibition matters
MAO inhibitors can affect how your body processes other substances, which is why interactions are important. While selegiline is more selective for MAO-B at typical doses, it can still interact with medicines that affect serotonin or other pathways.
Pharmacokinetics (Absorption, Distribution, Metabolism, Excretion)
Understanding pharmacokinetics can help you anticipate how your body handles the medicine and why timing matters. Individual results vary with age, liver function, and other medications.
Absorption
Selegiline is absorbed after oral dosing. The exact speed and extent of absorption can vary by formulation and individual factors.
Distribution
Selegiline and its metabolites distribute throughout the body, including the central nervous system, where it exerts its effects.
Metabolism
Selegiline is metabolised primarily in the liver. It can convert into metabolites that may contribute to both therapeutic effects and side-effect profiles.
Elimination
The medicine and its metabolites are eliminated mostly via the kidneys. In people with significant kidney or liver impairment, levels can change—your clinician may adjust decisions accordingly.
Onset and duration
Some benefits for Parkinson’s symptoms may be noticed gradually as treatment continues, though individual response varies. The overall clinical effect depends on dose, disease stage, and whether you are taking other Parkinson’s medicines.
Typical Use and Indications in Australia
The most well-established role for Eldepryl (selegiline) is in Parkinson’s disease. It may be used to improve symptoms and/or as part of broader Parkinson’s management strategies.
Parkinson’s disease
- May help reduce symptoms related to dopamine deficiency
- Sometimes used in combination with other Parkinson’s medications, depending on your situation
Mood-related use (select contexts)
In some clinical settings, selegiline has been used as an adjunct in depressive illness. However, this is a specialist-led approach and depends on individual assessment, current medicines, and safety considerations.
If you’re unsure why you were given Eldepryl, speak with your pharmacist or doctor for clarification.
Dosing: How to Take Eldepryl (Selegiline)
Dosing must be individualised. Below are general guidance points about how MAO-B inhibitors like selegiline are commonly scheduled. Always follow the schedule provided with your product and your healthcare team’s instructions.
General dosing principles
- Start low and adjust gradually if needed, based on response and side effects.
- Take at consistent times each day to maintain steady effect.
- Timing can affect sleep: many people are advised to take earlier in the day.
- Do not double doses if you miss one—ask for advice on what to do.
Typical timing guidance
A common practical approach is:
- Once daily: usually in the morning or early afternoon
- Twice daily regimens (if applicable to your product): spacing doses through the day, avoiding late evening
Your exact instructions may differ depending on the indication and product strength.
How to take the tablet
- Swallow with water.
- Keep your routine consistent (e.g., with or without food—follow your product label guidance).
- If you have swallowing difficulties, ask a pharmacist about options (e.g., whether the tablet can be split—only if permitted for your specific product).
Food Interactions
Food interactions depend on how medicines are metabolised and the presence of certain amino acids. For MAO inhibitors, the classic concern has been tyramine (“tyramine food” interactions can trigger high blood pressure in certain MAO inhibitor settings).
With selegiline (typical MAO-B dosing)
At typical MAO-B selective doses, strict tyramine dietary restrictions are often less necessary than with older non-selective MAO inhibitors. Still, it’s wise to be cautious with large or unusual tyramine intake—especially when starting treatment or changing dose.
Practical food tips
- Avoid sudden increases in aged, fermented, or pickled foods.
- Be cautious with very high-tyramine meals (e.g., large servings of aged cheeses or cured meats).
- If you notice symptoms such as throbbing headache or palpitations after certain foods, seek advice.
Your pharmacist can provide clearer guidance based on your exact dose and product.
Alcohol and Medicine Interactions
Alcohol can worsen dizziness, sleep disturbance, mood changes, and blood pressure fluctuations. Because selegiline affects neurotransmitters and is a MAO-B inhibitor, combining it with alcohol may increase side effects.
Alcohol
- General advice: avoid or limit alcohol while taking Eldepryl.
- If you choose to drink, do so cautiously and do not drive if you feel drowsy or unwell.
- Tell your healthcare team if you have a history of alcohol misuse.
Important medicine interactions
Some combinations can raise the risk of serious reactions, including hypertensive episodes or serotonin-related syndromes. Interactions may also involve drugs that increase dopamine or affect adrenaline/serotonin pathways.
Talk to your pharmacist before combining Eldepryl with:
- Antidepressants (especially SSRIs, SNRIs, tricyclic antidepressants, and certain others)
- Serotonin-modifying medicines (e.g., linezolid—an antibiotic with MAO activity—requires particular caution)
- Opioids that can interact with serotonin pathways (some combinations can increase risk of serotonin toxicity)
- Stimulants (including some cold/flu medicines containing stimulants)
- Other MAO inhibitors (avoid unless specifically directed)
- Medicines for migraines (some migraine treatments have serotonergic activity)
- Herbal products such as St John’s wort (can affect monoamine balance)
Always provide your pharmacist with a complete list of medicines, including non-prescription medicines, vitamins, and herbal supplements.
Timing: When to Take Eldepryl
Timing is especially relevant for selegiline due to potential effects on sleep and alertness. Many people find it helpful to take it earlier in the day.
- Morning/early afternoon is often preferred.
- Avoid taking late in the day if it disrupts sleep.
- If your regimen changes, ask for timing advice so your routine stays stable.
If you miss a dose, follow the advice on your packaging or from your pharmacist. As a general principle, it’s usually better not to “catch up” late in the day if it could affect sleep.
Safety Profile: Side Effects and When to Get Help
Most people tolerate Eldepryl reasonably well, but side effects can occur. The risk depends on dose, other medicines, and individual health factors. If you experience any concerning symptoms, seek medical advice promptly.
Common side effects
- Insomnia or sleep disturbance
- Nausea or stomach upset
- Dizziness or light-headedness
- Headache
- Dry mouth
Less common but important side effects
- Blood pressure changes (including episodes of high blood pressure, particularly with interacting foods/medicines)
- Palpitations
- Tremor or agitation
- Confusion or unusual behaviour
Seek urgent medical advice if you get
Contact emergency services or urgent medical care if you develop symptoms suggestive of serious drug interactions, including:
- Severe headache with chest pain, shortness of breath, or visual changes
- Very high blood pressure symptoms (e.g., intense headache, palpitations, sweating)
- Signs of serotonin-related toxicity such as fever, severe agitation, confusion, muscle stiffness, or diarrhoea (especially if combined with serotonergic medicines)
- Fainting or severe dizziness
Who should be extra cautious
- People with liver impairment
- People with cardiovascular problems (e.g., unstable blood pressure)
- People taking multiple medicines that can affect neurotransmitters
- Older adults who may be more sensitive to dizziness or sleep effects
Practical Use Tips (Day-to-Day)
- Keep a medicine routine: using a pill organiser or phone reminder can improve consistency.
- Track side effects: note sleep changes, dizziness, or mood changes and share them with your pharmacist/doctor.
- Avoid sudden medicine changes: don’t stop or start antidepressants, cold/flu tablets, or supplements without checking interactions.
- Be cautious with “over-the-counter”: some cold/flu and pain products may contain ingredients that can interact.
- Hydrate and stand up slowly: if you feel light-headed, slow rises from sitting/lying can help reduce falls.
- Don’t drive if you’re affected: if dizziness or sleepiness occurs, avoid driving and operating machinery.
What to do if you miss a dose
Follow the instructions provided with your medicine. In general, if you remember shortly after the scheduled time, you may take it. If it’s close to the next dose—or late in the day—skip the missed dose rather than taking it late.
Alternative Options
Treatment plans for Parkinson’s disease and mood conditions are individualised. If Eldepryl isn’t suitable (due to side effects, interactions, or response), alternatives may include other medication classes or non-drug therapies. Discuss options with a clinician.
For Parkinson’s disease
- Other MAO-B inhibitors (e.g., alternatives may be considered depending on availability and suitability)
- Dopamine pathway therapies such as levodopa and dopamine agonists (chosen based on symptoms and stage)
- COMT inhibitors in selected cases to help levodopa effects last longer
- Anticholinergic or other adjunct treatments for specific symptoms
- Physiotherapy and exercise programs for function and mobility
For depressive symptoms
Depending on your diagnosis and risk profile, clinicians may consider other antidepressant strategies, psychotherapy, or combined approaches. If you are exploring alternatives, make sure to discuss interaction risks—especially when switching between medicines that affect serotonin.
