Sexual health does not stop mattering when a neurological condition arrives. Men living with Parkinson’s disease, and the partners and carers who support them, often deal with a tangle of changes: stiffness and tremor, shifts in mood, and effects on desire, erections and ejaculation. When someone in that situation asks a doctor, or a website, about a medicine for premature ejaculation, a name like dapoxetine can surface. If that person also takes selegiline, a pharmacist has a very specific reason to pause.
This guide is written with two readers in mind: the person taking the medicines and the family member or carer who helps manage them. It explains why dapoxetine and selegiline are flagged, what a pharmacist actually checks, and how to build a simple routine that keeps everyone on the same page.
Short Answer
Selegiline is a monoamine oxidase inhibitor (MAOI). Dapoxetine product information says that MAOIs must not be used with dapoxetine, or within 14 days of stopping an MAOI, and that an MAOI should not be started within 7 days after the last dapoxetine dose. The selegiline prescribing information in turn warns about serious reactions with serotonergic antidepressants. Even though selegiline is described as “selective” at low oral doses, pharmacists do not treat that as a loophole. If both medicines are on the table, the answer is to stop, check and ask the prescriber, not to experiment.

Selegiline in Plain Language
Selegiline blocks monoamine oxidase type B (MAO-B), an enzyme that breaks down dopamine in the brain. In Parkinson’s disease, slowing dopamine breakdown helps stretch the benefit of levodopa and other treatments. You may see selegiline described in several forms:
- Oral tablets and capsules used for Parkinson’s disease
- Orally disintegrating tablets that dissolve on the tongue
- Transdermal patches licensed in some countries for depression, which deliver the drug through the skin and are treated as MAOI antidepressants
Related medicines in the same family include rasagiline and safinamide, which are also MAO-B inhibitors. Pharmacists apply similar caution to these, though the details are different. If you take any of them, mention it by name.
Why “Selective” Does Not Mean “Safe to Combine”
Many leaflets and websites call selegiline a selective MAO-B inhibitor. At the lower oral doses used in Parkinson’s disease, it mostly acts on MAO-B and has less effect on MAO-A, the form most tied to serotonin and the dietary tyramine issues seen with older MAOIs. That distinction is real, and it is why people on low-dose oral selegiline do not usually need the strict diet of older drugs.
The catch is that selectivity is dose-dependent. At higher doses, and with some formulations such as the patch, selegiline loses selectivity and inhibits MAO-A as well. Individual responses also vary. For a pharmacist, that uncertainty is enough to treat selegiline as an MAOI whenever serotonergic medicines are involved.
What each side’s labelling says
- Dapoxetine: product information, including the Irish HPRA summary for Priligy, lists concomitant MAOI treatment as a contraindication, along with use within 14 days of stopping an MAOI. It also says an MAOI should not be given within 7 days after dapoxetine has been stopped.
- Selegiline: prescribing information warns of severe, sometimes fatal reactions when it is combined with certain antidepressants, including SSRIs, and sets waiting periods when switching. It also warns against several opioids, including tramadol and meperidine, as well as dextromethorphan and St John’s wort.
When two labels warn about each other, the message is clear. This is a pair that needs professional oversight.
Parkinson’s and Sexual Health: The Bigger Picture
People with Parkinson’s disease often report sexual difficulties, but premature ejaculation is only one possibility, and not always the most common. Other issues include reduced desire, erectile difficulty, delayed or difficult ejaculation, low mood or anxiety, tiredness, and changes in how a partner feels in the relationship. Some Parkinson’s medicines can also affect impulse control, which can change sexual behaviour. Doctors who understand these links can sometimes adjust treatment rather than add another tablet.
That is why a pharmacist or neurologist may ask broader questions than you expect. Before any new sexual-health medicine, it helps to know:
- Is the issue new, or has it changed since a Parkinson’s medicine was started or adjusted?
- Is anxiety or low mood contributing?
- Are there blood pressure or dizziness problems that affect which options are safe?
- Would non-drug approaches help first?
Our guides on dealing with premature ejaculation in a relationship and beating psychological erectile dysfunction cover communication and behavioural approaches that do not depend on interacting medicines.
Six Checks a Pharmacist Makes
| Check | What they are looking for | Helpful to bring |
|---|---|---|
| 1. Exact selegiline product | Tablet, capsule, orally disintegrating form or patch, and the dose | The box or pharmacy label |
| 2. Other MAO-B inhibitors | Rasagiline or safinamide, which may be on the list instead of or alongside selegiline | A neurologist’s letter or medicine chart |
| 3. Source of dapoxetine | Whether it was prescribed, bought in a pharmacy or ordered online; the strength; the date of the last dose | The original packaging |
| 4. Other serotonergic drugs | Antidepressants, tramadol, triptans, lithium, linezolid, St John’s wort, dextromethorphan | A full list including over-the-counter items |
| 5. Cardiovascular and fainting history | Orthostatic hypotension, syncope, heart rhythm problems | Recent blood pressure readings |
| 6. Mood and cognition | Depression, mania history, confusion or hallucinations, which affect which medicines are suitable | Input from the neurologist or carer |
The Blood Pressure and Fainting Overlap
Interaction talk usually focuses on serotonin, but a second concern is more mundane and just as real. Parkinson’s disease itself can cause drops in blood pressure on standing (orthostatic hypotension), and several Parkinson’s medicines can add to that effect. Dapoxetine labelling lists a history of fainting as a reason not to use it, and its product information describes dizziness and fainting as adverse effects. For someone who already feels light-headed when getting out of a chair, that is a meaningful extra risk, because falls in Parkinson’s disease can lead to fractures and hospital stays.
So even before the MAOI interaction is considered, a pharmacist may judge dapoxetine unsuitable for a given person. This is not a reflection on the sexual concern. It is a safety judgement based on how the whole body works.
Everyday precautions worth discussing with the care team
- Rising slowly from lying or sitting
- Staying hydrated, unless fluid is restricted for another reason
- Reviewing alcohol use, which can add to dizziness and fainting
- Checking all new medicines, even those that seem unrelated
If-Then Guide for Common Situations
These scenarios are for orientation only. Your own prescriber should make the final call.
| If this is your situation | Then the usual next step is |
|---|---|
| You take selegiline and are curious about dapoxetine | Do not start it. Ask your neurologist or pharmacist about other ways to address premature ejaculation. |
| You took dapoxetine recently and a doctor wants to start selegiline | Tell the prescriber the date of your last dapoxetine dose. Product information advises a 7-day gap before an MAOI is started. |
| You took both by mistake | Stop further doses. Check for warning signs. Call a pharmacist or doctor straight away, or seek emergency care if symptoms appear. |
| You are stopping selegiline and want to use dapoxetine | The label gap is 14 days after stopping the MAOI. Do not stop selegiline on your own; it must be done under medical supervision. |
| You bought dapoxetine online and cannot confirm its contents | Do not use it with selegiline. Show the pharmacist the packaging so they can advise. |
| Your carer manages your pill box | Make sure the carer knows about every sexual-health product and shares the list with the pharmacist. |
Warning signs that need urgent attention
- Agitation, confusion or hallucinations
- Heavy sweating, shaking or muscle twitching
- Fast or irregular heartbeat
- Fever or very stiff muscles
- Severe headache or sudden high blood pressure
- Fainting
Any of these after combining an MAOI with a serotonergic medicine is a reason to seek emergency care.
A Carer’s Role
When someone else helps with medicines, they often become the person who knows what is in the pill organiser. That is a strength, and it comes with responsibility. Carers can help by:
- Keeping an up-to-date medicine list, including supplements and anything bought outside the pharmacy
- Making sure sexual-health products are not hidden from the care team out of embarrassment
- Attending appointments, where permitted, to hear instructions about timing and warning signs
- Knowing the emergency plan: who to call and what to say
- Respecting privacy. The person taking the medicine decides how much to share and with whom.
Sexual health is part of overall wellbeing, and care teams are used to discussing it. Opening that conversation early often prevents a risky workaround later.
Safer Directions to Explore With the Care Team
The pharmacist’s role is not only to say no. Questions you can raise with the neurologist, urologist or sexual-health clinician include:
- Could any current Parkinson’s medicine be contributing to the problem, and is adjustment possible?
- Is anxiety or low mood playing a role, and would counselling or sex therapy help?
- Would behavioural techniques such as start-stop, squeeze methods or pelvic floor training be suitable?
- Are there topical or non-serotonergic options that fit with the rest of the medicine list?
- If erectile dysfunction is also present, which treatments are safe given blood pressure and other medicines? See what is the safest drug for erectile dysfunction for context.
Lifestyle and supplement articles such as foods for premature ejaculation and vitamins for premature ejaculation can be useful background, but always run any supplement past the pharmacist first. Several, including St John’s wort, are specifically problematic with MAOIs.

Frequently Asked Questions About Dapoxetine and Selegiline
Can you take dapoxetine if you are on selegiline?
Dapoxetine product information contraindicates MAOIs, and selegiline is an MAOI. You should not combine them unless a prescriber who knows your full situation specifically directs otherwise, which is unlikely.
Is low-dose selegiline different from other MAOIs?
At low oral doses it mainly inhibits MAO-B, so the dietary restrictions are lighter than with older MAOIs. Selectivity fades at higher doses and with some formulations, and pharmacists still treat it cautiously around serotonergic drugs.
How long after stopping selegiline can dapoxetine be used?
The dapoxetine label sets the gap at 14 days after stopping an MAOI. Never stop selegiline without medical guidance, because it can worsen Parkinson’s symptoms.
How long after dapoxetine can selegiline be started?
The label states that an MAOI should not be given within 7 days after dapoxetine has been stopped.
Does rasagiline or safinamide carry the same warning?
They are also MAO-B inhibitors, and pharmacists apply similar caution. Check the leaflet and ask the pharmacist about your specific product.
What if my carer ordered dapoxetine online for me?
Do not use it until the pharmacist has reviewed it. Unregulated products may contain different strengths or ingredients than the label states.
Are there safer options for premature ejaculation if I take selegiline?
Possibly. Behavioural techniques, counselling, pelvic floor work and some topical products may suit you. A clinician who knows your Parkinson’s treatment can advise.
Can Parkinson’s itself cause sexual problems?
Yes. Parkinson’s disease and some of its treatments can affect desire, erections, ejaculation and mood. It is worth raising with the care team.
Final Thoughts
The pairing of dapoxetine and selegiline sits at the meeting point of two real needs: managing Parkinson’s disease and keeping intimacy and confidence intact. A pharmacist’s checks can feel like obstacles, but each one is a way of protecting that balance. Bring the whole medicine list, include the carer where appropriate, and treat the 14-day and 7-day windows as firm limits. Then work with the care team on options that respect the interaction rather than ignore it.
