Priligy (Dapoxetine): How It Works, Side Effects & Taking It with Viagra or Cialis
Priligy is the brand name for dapoxetine, the first oral medicine developed specifically to treat premature ejaculation (PE). It is taken only when needed, a few hours before sex, rather than every day.
Premature ejaculation is one of the most common sexual concerns in men, yet many never speak to a doctor about it. This guide explains how dapoxetine works, what side effects to expect, why it is not the same as Viagra, and when a doctor may prescribe it alongside an erectile dysfunction (ED) medicine.
Quick answer
- Priligy (dapoxetine) treats premature ejaculation. Viagra (sildenafil) and Cialis (tadalafil) treat erectile dysfunction.
- It is taken 1 to 3 hours before sex, no more than once in 24 hours.
- The most common side effects are nausea, dizziness and headache.
- Avoid alcohol while taking it.
- It can be prescribed with Viagra or Cialis for men who have both PE and ED, but only after a doctor’s assessment.
- Dapoxetine is a prescription medicine in Malaysia.
How does dapoxetine work?
Dapoxetine is a short-acting selective serotonin reuptake inhibitor (SSRI). Serotonin is a brain chemical that helps control the ejaculation reflex. By briefly raising serotonin levels, dapoxetine delays that reflex and gives men more control over timing.
Unlike SSRIs used for depression, dapoxetine is absorbed quickly and leaves the body quickly. It reaches peak levels in about 1 hour, and most of it is cleared within 24 hours. That is why it can be taken on demand instead of daily.
In clinical trials, men taking dapoxetine lasted roughly 2.5 to 3 times longer on average than before treatment. Results vary from person to person.
How to take Priligy
- Take one tablet 1 to 3 hours before sexual activity, swallowed whole with a full glass of water.
- It can be taken with or without food.
- The usual starting dose is 30 mg. Your doctor may increase it to 60 mg if 30 mg is not effective and side effects are tolerable.
- Do not take more than one dose in 24 hours.
- Your doctor will usually review your response after the first 4 weeks or 6 doses.
Dapoxetine is intended for men aged 18 to 64 who have been diagnosed with premature ejaculation. It is not a treatment for low libido or erectile dysfunction.
Is dapoxetine the same as Viagra?
No. Dapoxetine treats premature ejaculation by acting on serotonin in the brain. Viagra and Cialis treat erectile dysfunction by increasing blood flow to the penis. They solve different problems and work in different parts of the body.

A man with PE alone usually does not need Viagra or Cialis. A man with ED alone will not get a firmer erection from dapoxetine. Some men have both conditions, which is where combined treatment comes in.
Can you take dapoxetine with Viagra or Cialis?
Yes, in some cases, but only when a doctor prescribes the combination. Premature ejaculation and erectile dysfunction often occur together. Some men rush to ejaculate because they worry about losing their erection, so treating both conditions can work better than treating one.
Studies of dapoxetine combined with sildenafil or tadalafil have generally found the combination well tolerated in men with both conditions. The main concern is that both types of medicine can lower blood pressure. Together they may make dizziness or fainting more likely, especially when standing up quickly.
Before prescribing both, a doctor will usually:
- Confirm that you have both PE and ED, not just one.
- Check your heart health, blood pressure and current medicines.
- Start with the lowest dose of each.
- Advise you to avoid alcohol and to sit or lie down if you feel lightheaded.
Never take Viagra or Cialis with nitrates (such as glyceryl trinitrate for chest pain) or with recreational “poppers”, with or without dapoxetine. This combination can cause a dangerous drop in blood pressure.
A note on “combo” pills sold online
Some websites sell tablets that combine sildenafil or tadalafil with dapoxetine in a single pill. Check that any medicine you buy carries a MAL registration number from Malaysia’s National Pharmaceutical Regulatory Agency (NPRA). Unregistered products may contain the wrong dose, undeclared ingredients, or no active ingredient at all.
Is dapoxetine safe?
For most healthy men, dapoxetine is safe when prescribed by a doctor and taken as directed. Side effects are usually mild and short-lived because the medicine leaves the body quickly.
Common side effects
- Nausea (the most frequently reported)
- Dizziness
- Headache
- Diarrhoea
- Trouble sleeping
- Tiredness
Fainting
A small number of men faint after taking dapoxetine, usually within the first few hours. Warning signs include nausea, lightheadedness and sweating. If you notice these, lie down with your head low or sit with your head between your knees until they pass. Do not drive or operate machinery until you know how the medicine affects you. Taking each dose with a full glass of water and avoiding dehydration can lower the risk.
Who should not take dapoxetine
- Men with heart failure, heart rhythm problems, significant coronary artery disease or heart valve disease
- Men with a history of fainting
- Men with a history of mania, bipolar disorder or severe depression
- Men with moderate to severe liver problems
- Men under 18 or over 64
Medicines that should not be combined with dapoxetine
- Antidepressants, including other SSRIs, SNRIs, tricyclics and MAO inhibitors (and for 14 days after stopping them)
- Other medicines that raise serotonin, such as tramadol, lithium, triptans for migraine, linezolid and St John’s wort
- Strong CYP3A4 inhibitors, including ketoconazole, itraconazole, ritonavir and clarithromycin
- Thioridazine
Always tell your doctor about every medicine and supplement you take, including blood pressure tablets and ED medicines.
Can you drink alcohol with dapoxetine?
It is best to avoid alcohol when taking dapoxetine. Alcohol and dapoxetine both affect the brain and blood pressure, and together they increase the risk of dizziness, drowsiness, slowed reactions and fainting.
If you do drink, keep it light, never drink heavily on the same day, and do not drive. Adding Viagra or Cialis on top raises the risk further, because all three can lower blood pressure.
