Dapoxetine is a short-acting SSRI developed specifically for premature ejaculation. Unlike antidepressants in the same class, it is taken on demand a few hours before sex rather than daily, because it is absorbed and cleared quickly.
This guide covers what premature ejaculation actually is, how dapoxetine works, its side effects, and the regulatory position that anyone buying it should understand.
Short answer: Dapoxetine is taken 1–3 hours before sex at 30mg or 60mg, no more than once in 24 hours. It typically extends time to ejaculation by around three-fold. Common side effects are nausea, dizziness, headache and, importantly, fainting. It is approved in many countries but not by the FDA in the United States. It is prescription-only wherever it is licensed.
What Premature Ejaculation Is
Clinically, PE is defined by three things together: ejaculation occurring sooner than desired — often within about a minute of penetration — an inability to delay it, and resulting distress. That last element matters. Occasional rapid ejaculation is common and is not a disorder without distress.
It comes in two forms:
- Lifelong — present from first sexual experiences, more often with a neurobiological basis relating to serotonin signalling
- Acquired — developing after a period of normal function, more often linked to anxiety, relationship factors, thyroid disease, prostatitis, or erectile dysfunction
That distinction guides treatment. Acquired PE frequently has a treatable cause behind it — and one in particular is often missed.
The Overlap With Erectile Dysfunction
Men with erectile difficulty sometimes rush to ejaculate before losing the erection, producing what looks exactly like premature ejaculation. Treating the PE alone will not help; treating the erectile dysfunction often resolves both.
This is why assessment matters before self-medicating. Treatments for erectile dysfunction sit under Erectile Dysfunction, and some products combine both actions — Super P Force contains sildenafil and dapoxetine together, which is appropriate only when both conditions are genuinely present and a doctor has confirmed it.
How Dapoxetine Works
Serotonin delays ejaculation. SSRIs raise serotonin levels, which is why men taking antidepressants often notice delayed ejaculation as a side effect. Dapoxetine exploits that effect deliberately, but its short half-life means it acts within hours and clears quickly, so it can be used on demand rather than continuously.
Dosage
- 30mg is the usual starting dose; 60mg where 30mg is insufficient and tolerated
- Take 1–3 hours before sexual activity
- Maximum once in 24 hours
- Swallow whole with a full glass of water — this reduces fainting risk
- Do not drink alcohol with it — the combination markedly increases dizziness and fainting
Dapoxetine products sit under Dapoxetine, including Poxet 60 Mg.
Side Effects
Common
- Nausea — the most frequent
- Dizziness
- Headache
- Diarrhoea
- Insomnia
- Dry mouth
The One That Matters Most
Fainting (syncope), sometimes preceded by dizziness or sweating. This is a recognised effect and the reason for taking it with a full glass of water and avoiding alcohol. If you feel lightheaded, lie down with your legs raised. Do not drive or operate machinery until you know how it affects you.
Seek Medical Advice For
- Fainting or near-fainting episodes
- Mood changes, agitation, or thoughts of self-harm
- Symptoms of serotonin syndrome — agitation, fever, rapid heartbeat, muscle rigidity, confusion — particularly if taken with other serotonergic drugs
Who Should Not Take It
- Men with significant heart disease, heart failure, or conduction abnormalities
- Anyone with a history of fainting
- Anyone with mania, bipolar disorder, or significant depression
- Anyone taking MAO inhibitors, thioridazine, other SSRIs or SNRIs, lithium, tramadol, St John’s Wort or triptans — serotonin syndrome risk
- Anyone on potent CYP3A4 inhibitors such as ketoconazole, itraconazole or ritonavir
- Moderate or severe liver impairment
- Men under 18 or over 64
Regulatory Status — Worth Knowing
Dapoxetine is approved in a number of countries in Europe, Asia and elsewhere, but it has never been approved by the FDA in the United States. It is not available on prescription there, and it does not appear in US drug references such as MedlinePlus for that reason.
That has a practical consequence: US buyers encounter it only through import, where manufacturing standards and actual content are harder to verify. Where premature ejaculation is treated in the US, doctors typically prescribe a conventional SSRI such as sertraline or paroxetine off-label, or a topical anaesthetic.
Alternatives
- Topical anaesthetics — lidocaine or prilocaine sprays and creams reduce sensitivity; used with a condom to avoid transferring numbness to a partner
- Daily SSRIs off-label — sertraline, paroxetine or fluoxetine, prescribed and monitored by a doctor
- Behavioural techniques — the stop-start and squeeze methods, which have reasonable evidence, particularly alongside medication
- Pelvic floor exercises — a growing body of evidence supports these for ejaculatory control
- Psychosexual therapy — especially where anxiety or relationship factors are involved
- Treating the underlying cause — erectile dysfunction, thyroid disease or prostatitis
Background on the condition is set out in the MedlinePlus entry on premature ejaculation and its overview of sexual problems in men.
Frequently Asked Questions
How do I stop premature ejaculation?
Options include behavioural techniques, pelvic floor training, topical anaesthetics, on-demand dapoxetine where licensed, daily SSRIs prescribed off-label, and treating any underlying cause such as erectile dysfunction or thyroid disease.
How long before sex should dapoxetine be taken?
One to three hours, with a full glass of water, and no more than once in 24 hours.
How effective is it?
Trials show roughly a three-fold increase in time to ejaculation. It manages the symptom while in the system rather than curing the condition.
Can I drink alcohol with dapoxetine?
No. Alcohol substantially increases dizziness and fainting, and this is one of the more serious risks with this drug.
Is dapoxetine approved in the US?
No. It has never received FDA approval. US doctors typically use conventional SSRIs off-label or topical anaesthetics instead.
Can I take it with ED medication?
Only under medical supervision. Combination products exist, but both drugs lower blood pressure and the combination increases dizziness and fainting risk.
Is premature ejaculation permanent?
No. Lifelong PE is usually managed long term, while acquired PE often resolves when the underlying cause is treated.
Do I need to see a doctor?
Yes. Dapoxetine is prescription-only where licensed, has significant cardiac and psychiatric contraindications, and interacts dangerously with several common medicines. Assessment also identifies causes that would otherwise be missed.
Health and Medical Disclaimer
This article is general information, not medical advice, and does not replace consultation with a qualified healthcare professional. Dapoxetine is a prescription-only medicine where it is licensed and is not approved by the FDA in the United States. It can cause fainting, must not be combined with alcohol, and is contraindicated with MAO inhibitors, other SSRIs and several common medicines because of the risk of serotonin syndrome. It is unsuitable for men with heart disease or a history of fainting. Seek medical assessment before use.
