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

Eldepryl is a brand name for selegiline, a medicine that affects brain chemicals involved in mood and movement. It is most well known for use in Parkinson’s disease. In some countries, including the UK, selegiline is also used as an add-on treatment in certain depression-related situations depending on local prescribing practice and availability.

This guide explains what Eldepryl is, how it works, how it behaves in the body, typical uses, practical tips for taking it safely, important interactions (including with alcohol and other medicines), and what to expect regarding safety and availability in the United Kingdom.

Basic product information

How Eldepryl works (mechanism of action)

Selegiline works by inhibiting an enzyme called monoamine oxidase type B (MAO‑B) in the brain. MAO‑B normally breaks down certain brain chemicals, including dopamine.

By blocking MAO‑B, Eldepryl helps to reduce the breakdown of dopamine. This can improve movement symptoms in Parkinson’s disease by supporting dopamine signalling. Depending on the overall treatment plan, it may also contribute to smoother “on/off” control when used alongside other Parkinson’s medicines.

Pharmacokinetics: what the medicine does in the body

“Pharmacokinetics” describes how the body absorbs, processes, and eliminates a medicine. While individual responses vary, the following points help explain typical behaviour:

• Absorption: Selegiline is absorbed after oral dosing. Food can influence the speed and extent of absorption for some formulations, but many patients can take it with guidance provided below.
• Distribution: Selegiline reaches the brain, where MAO‑B inhibition occurs.
• Metabolism: The drug is metabolised in the liver to various compounds (including active metabolites).
• Elimination: Metabolites are excreted mainly via the kidneys (urine) and partly through other routes.
• Duration of effect: Because MAO‑B inhibition affects dopamine breakdown, effects can last beyond the dosing interval. Clinicians often tailor timing to balance benefit with side effects such as insomnia.

If you have liver or kidney problems, your clinician or pharmacist may adjust advice and monitoring. Always follow the exact plan given for your situation.

Typical use in the UK

In the UK, Eldepryl (selegiline) is primarily used for:

• Parkinson’s disease, commonly to help improve motor symptoms and/or reduce fluctuation when used with other therapies. It may be used early in the disease course or as part of combination regimens depending on individual need.
• Depression in certain treatment strategies: in some settings, selegiline has been used as a component of depression treatment (commonly in combination strategies). Local availability and practice vary.

Whether selegiline is appropriate for you depends on your diagnosis, other medicines, and medical history. Your pharmacist can help check interactions and suitability.

Indications: what Eldepryl is meant to treat

“Indication” means the condition(s) a medicine is intended to treat. For Eldepryl, indications in routine UK use mainly include:

• Parkinson’s disease (symptomatic treatment, typically as an add-on or part of ongoing therapy).
• Selected depression-related indications depending on clinical assessment and local treatment pathways.

If you are unsure why you have been given Eldepryl, ask your pharmacist or clinician. Using it for a different purpose may not be safe.

Dosing: how to take Eldepryl

Dosing is individual. The correct dose depends on your condition, response, age, and interactions with other medicines. Always follow the specific instructions given to you.

General guidance:

• Eldepryl is usually taken by mouth.
• It is commonly taken once or twice daily, depending on the strength and your clinician’s plan.
• The dose may be adjusted gradually based on symptom control and tolerability.
• Do not change your dose or stop suddenly without advice, especially in Parkinson’s disease.

If you miss a dose, take it when you remember unless it is close to the time for your next dose. Do not take two doses at once to make up for a missed dose. If you are uncertain, ask your pharmacist.

Timing: when to take it for best effect

Many people find that selegiline can affect sleep. Therefore, timing matters. A common approach is to take it in the morning and avoid late-evening doses unless your prescriber has advised otherwise.

• Morning dose: often preferred to reduce the risk of insomnia.
• Second dose (if prescribed): if taken twice daily, it is usually taken earlier in the day.
• Steady routine: taking at similar times each day can improve consistency.

If you notice sleep disturbance, agitation, or vivid dreams, speak to your pharmacist or clinician. They may adjust timing or dose.

Food interactions: can you take Eldepryl with meals?

Food effects can vary depending on formulation and individual factors. In practice, many patients can take selegiline with or without food.

Practical advice:

• If you experience stomach upset, taking with a light meal may help.
• Maintain consistency—if you usually take it with breakfast, continue that routine.
• If your clinician or pharmacist provided specific instructions for your product, follow those first.

Alcohol and medicine interactions

Selegiline can interact with alcohol and with other medicines in ways that may increase side effects such as blood pressure changes, dizziness, or sedation.

Alcohol

• It is generally advisable to limit or avoid alcohol while taking Eldepryl, especially if you are prone to dizziness or low blood pressure.
• Alcohol may worsen sleep disruption and increase the risk of falls in some people.

Important medicine interactions

Selegiline affects monoamine metabolism. This is why several classes of medicines must be handled carefully. Always provide your pharmacist with a full list of medicines, including over-the-counter products and supplements.

Key interaction groups to discuss:

• Antidepressants (particularly certain types): combining MAO‑B inhibitors with some antidepressants can increase the risk of serious reactions.
• Opioid pain medicines: some opioids may interact through effects on serotonin pathways or blood pressure.
• Triptans (migraine medicines): ask before combining.
• Sympathomimetic decongestants (for example, some cold/flu products): may increase cardiovascular side effects.
• Stimulants: may increase jitteriness, anxiety, or insomnia.
• Other MAO inhibitors: generally not combined unless specifically advised by a specialist.

Because interaction risk depends on dose and the exact medicine, your pharmacist is the best source for tailored advice. If you have recently started or stopped any antidepressant or migraine medicine, inform them promptly.

Safety profile: who should be careful and what to watch for

Like all medicines, Eldepryl can cause side effects. Not everyone gets them, and many are manageable. However, some symptoms may indicate a serious problem and require urgent medical advice.

Common or expected side effects

• Dizziness or light-headedness (especially when standing up)
• Headache
• Nausea or indigestion
• Sleep changes such as insomnia or vivid dreams
• Dry mouth
• Agitation or restlessness (occasionally)

Seek urgent advice if you experience

Contact urgent care or a medical professional immediately if you experience severe or concerning symptoms, such as:

• Severe confusion, agitation, high fever, or marked muscle stiffness (could indicate a serious drug reaction).
• Fainting, chest pain, or severe shortness of breath.
• Severe headache with vision changes or neurological symptoms.
• Signs of an allergic reaction (for example swelling of face/lips, wheeze, or a widespread rash).

Special populations

• Older adults: may be more sensitive to dizziness and falls—rise slowly from sitting/lying positions.
• Liver impairment: may require extra caution and monitoring.
• Kidney impairment: discuss dosing and monitoring with your clinician.
• History of psychiatric illness: inform your clinician if you have previous episodes of mania, psychosis, or severe anxiety.

Practical use tips (to get the best from your treatment)

• Take at consistent times: routine helps symptom control and reduces sleep disruption.
• Watch for sleep effects: if you feel wired or cannot sleep, shift dosing to earlier (only if allowed by your plan) or contact your pharmacist.
• Stand up slowly: dizziness can be problematic; take extra care if you also take blood pressure medicines.
• Keep a medicine list: include over-the-counter products (especially cough/cold remedies) and herbal supplements.
• Do not “stack” serotonergic products: avoid adding new antidepressants, migraine medicines, or supplements without checking first.
• Use symptom notes: in Parkinson’s disease, tracking “on/off” periods, tremor changes, and mobility may help your clinician adjust treatment.

Alternative options

Depending on the condition being treated, alternative medicines may include:

• For Parkinson’s disease: other options may include levodopa preparations, dopamine agonists, COMT inhibitors, and other MAO-B inhibitors. Non-medicine options such as physiotherapy and occupational therapy also play an important role.
• For depression-related strategies: alternatives may include other antidepressants (selection depends heavily on your history and current medicines).

Your best alternative depends on your diagnosis, symptom pattern, and risk of interactions. Speak to your pharmacist or clinician before switching.
