Poxet is intended for adult men with premature ejaculation. Taken before anticipated sexual activity, it can delay ejaculation by increasing serotonin signalling in the nervous system.
Dapoxetine, the active ingredient of Poxet, is a short-acting selective serotonin reuptake inhibitor used for premature ejaculation in adult men.
Dapoxetine is taken by mouth as needed before anticipated sexual activity. The usual prescribing approach is:
Dosing differs between strengths and between users, so there is no single amount that suits everyone. Treatment commonly begins with the lower available strength. A higher strength may be considered when the response is inadequate and the lower dose has caused no troublesome adverse effects.
A missed dose does not require doubling the next dose. Since Poxet is used on demand, the next dose should only be taken before a later episode of sexual activity, while keeping to the one-dose-in-24-hours limit.
The tablet should be swallowed whole with water. If a tablet is crushed, chewed, or divided, the intended dose may not be delivered as designed and the bitter taste can be unpleasant. The product should not be combined with recreational drugs or medicines that affect serotonin, blood pressure, heart rhythm, or liver metabolism without a specific clinical review.
Poxet is supplied as oral tablets. Dapoxetine treatment uses dose adjustment rather than a fixed amount for every patient. The appropriate strength depends on response, tolerability, age, medical history, and interacting medicines.
The standard clinical approach uses a lower starting strength, with a higher strength considered only when the lower dose has not produced sufficient benefit and has been tolerated. Dosing differs between strengths and between users, so there is no single amount that suits everyone.
| Treatment approach | Clinical role | Practical point |
|---|---|---|
| Lower dapoxetine strength | Usual starting approach | Allows tolerability to be assessed |
| Higher dapoxetine strength | Considered after inadequate response | More adverse effects may occur |
| Poxet tablets | Oral, on-demand administration | Not intended for more than one dose in 24 hours |
Dapoxetine strengths are not interchangeable on a tablet-for-tablet basis. A higher dose can increase exposure without producing a proportional improvement in control. Medical assessment is needed before changing strength.
Poxet tablets contain dapoxetine, a short-acting SSRI developed for the management of premature ejaculation. Dapoxetine increases serotonin activity in nerve pathways involved in the ejaculatory reflex. This can lengthen intravaginal ejaculatory latency time and give a man greater control during sexual activity. [1]
Premature ejaculation involves several factors, including rapid ejaculatory reflexes, anxiety, learned responses, and altered neurotransmitter signalling. Serotonin helps regulate the timing of ejaculation in the central nervous system. Dapoxetine temporarily strengthens this signalling before sexual activity, rather than maintaining antidepressant-level exposure throughout the day.
Dapoxetine is absorbed and eliminated more quickly than SSRIs used for depression or anxiety. That pharmacokinetic profile supports occasional dosing. The medicine is intended to be taken when needed, not as a routine daily antidepressant.
Clinical trials evaluated dapoxetine using intravaginal ejaculatory latency time, or IELT. IELT measures the time from vaginal penetration to ejaculation. A longer IELT does not measure every aspect of sexual satisfaction, but it provides a consistent clinical endpoint for assessing treatment response.
The treatment may also reduce anticipatory anxiety. A man who has more predictable control may feel less pressure before intercourse, although dapoxetine does not replace psychological therapy when performance anxiety, relationship stress, or compulsive checking drives the problem.
Poxet may help men with diagnosed premature ejaculation delay ejaculation and improve perceived control. The clinical benefit is usually assessed over several attempts rather than after a single isolated experience. Dapoxetine has been studied in men with lifelong and acquired premature ejaculation, with improvements in IELT and patient-reported control reported in clinical trials. [2]
The psychological effect can be meaningful. Improved control may reduce the cycle of worry, rushing, and disappointment that often develops after repeated early ejaculation. Partners may also report improved satisfaction when intercourse becomes less predictable and less stressful.
Treatment has limits. Dapoxetine does not create sexual desire, treat erectile dysfunction directly, cure relationship conflict, or guarantee a specific duration of intercourse. It may also be less useful when ejaculation is secondary to untreated prostatitis, severe anxiety, medication effects, or another medical condition.
A practical clinical outcome is often a combination of modestly longer latency, improved confidence, and less avoidance of intimacy. Doctors normally assess all three rather than relying on timing alone. Response can vary between sexual encounters. Follow-up helps identify adverse effects and other causes of premature ejaculation. This broader assessment supports safer treatment decisions.
Several practical mistakes reduce the chance of a good result:
The most common dosing error is taking another tablet on the same day. More dapoxetine does not guarantee more control and can increase nausea, dizziness, fainting, and other adverse effects.
Another overlooked issue is dehydration. A hot bath, strenuous exercise, diarrhoea, and alcohol can all reduce circulating fluid volume, making postural dizziness more likely after dosing.
The combination with MAO inhibitors can produce dangerous changes in serotonin and blood pressure. A washout period may be needed when switching between serotonergic medicines. The exact interval depends on the medicine previously used.
Dapoxetine may interact with medicines for erectile dysfunction, alpha-blockers, nitrates, antihypertensives, and other treatments that reduce blood pressure. The combination can increase postural dizziness or fainting. Strong alcohol intake carries a similar concern.
Men with epilepsy, bleeding disorders, kidney disease, or a history of severe depression require a specific clinical assessment before use. The same applies to anyone taking tramadol, lithium, linezolid, St John’s wort, migraine medicines from the triptan group, or other medicines that increase serotonin.
NOT for you if you have unexplained fainting, significant heart disease, severe liver impairment, or relevant interacting medicines; discuss alternatives with a clinician.
The most frequently reported adverse effects of dapoxetine include nausea, dizziness, headache, diarrhoea, abdominal discomfort, insomnia, fatigue, and dry mouth. Clinical trial rates were generally higher with the 60 mg dose than with the 30 mg dose. The EMA product information identifies nausea and dizziness among the main reasons for stopping treatment. [3]
Most mild reactions occur near the time of dosing and settle as the medicine leaves the body. Nausea may be more noticeable when the tablet is taken with alcohol, after dehydration, or following a large meal. Dizziness can become more troublesome in hot weather, after exercise, or when combined with medicines that lower blood pressure.
Other possible reactions include:
Fainting is an important warning sign. Syncope can occur through a sudden fall in blood pressure or a vasovagal reaction. Stop sexual activity, sit or lie down, and seek urgent medical assessment if fainting, chest pain, severe palpitations, seizure, or an allergic reaction occurs.
One detail patients often miss is that dizziness may begin before the expected sexual activity. The medicine is not only active during intercourse; it can affect blood pressure and alertness during the hours after the tablet is taken.
Persistent low mood, agitation, unusual excitement, suicidal thoughts, or severe behavioural change require prompt clinical attention. Dapoxetine is not a suitable treatment for depression, and mood symptoms should not be self-managed by increasing the dose.
Dapoxetine differs from other approaches because it is a short-acting oral SSRI intended for on-demand use. Daily SSRIs may delay ejaculation but expose the body to continuous treatment and can cause persistent adverse effects. Topical anaesthetics reduce penile sensitivity locally, while behavioural therapy targets learned arousal and anxiety patterns.
| Approach | Main mechanism | Typical use pattern |
|---|---|---|
| Dapoxetine | Temporary increase in serotonin signalling | On demand before sexual activity |
| Daily SSRI therapy | Continuous serotonin reuptake inhibition | Regular daily treatment |
| Topical anaesthetic | Reduces local penile sensitivity | Applied before intercourse |
PDE5 inhibitors have a different primary role. They improve penile blood flow and are used for erectile dysfunction, not as direct serotonin-based treatments for premature ejaculation. They may be considered when erectile difficulty and early ejaculation occur together, but the choice depends on the clinical cause.
Topical anaesthetics can help some men, though excessive numbness may reduce pleasure for either partner. A condom or careful removal of residual product may be needed with certain topical preparations. Behavioural treatment avoids medicine-related dizziness but requires practice and active participation.
The best option depends on whether the main problem is ejaculation control, erection maintenance, anxiety, medication effects, or a combination of these factors. European clinical guidance supports a structured assessment rather than selecting treatment from timing alone. [4]
In clinical practice, doctors usually focus first on whether ejaculation occurs earlier than the man wants, whether the problem is persistent, and whether it causes distress. A short duration alone does not establish the diagnosis. The history should include onset, relationship context, erection quality, medication use, alcohol intake, and urinary or pelvic symptoms.
Dapoxetine is often considered when behavioural techniques alone have not provided enough control or when the patient prefers an on-demand option. The medicine works best when the dose is used consistently according to the prescribed plan and assessed across several sexual encounters.
A doctor will usually avoid increasing the dose simply because one attempt was disappointing. Alcohol, inadequate arousal, relationship tension, erectile difficulty, and unrealistic expectations can all distort the result. In some cases, treating erectile dysfunction or anxiety provides more benefit than raising the dapoxetine dose.
Psychosexual therapy can complement medication. Stop-start training, sensate-focus exercises, pelvic-floor rehabilitation, and couples counselling may be useful when the problem has a behavioural or relational component. These approaches are not substitutes for medical assessment when symptoms began suddenly or accompany pain, urinary symptoms, or loss of erection.
Poxet is usually used on demand rather than as a fixed daily course. The 2013 EMA product information describes treatment review after an initial period, with continued use based on benefit, tolerability, and an ongoing diagnosis of premature ejaculation. Long-term use should involve periodic clinical review rather than automatic continuation. [5]
Dapoxetine is generally taken one to three hours before anticipated sexual activity. Clinical information reviewed by the EMA in 2013 supports this timing for achieving useful exposure before intercourse. The first attempt may not show the full practical benefit because anxiety, timing, food, alcohol, and expectations can affect the experience.
A single dose is intended to support one episode of sexual activity during the hours after administration. Dapoxetine is short-acting, and its effect does not provide continuous protection throughout the day. The MHRA safety approach published in 2024 for medicines that can cause dizziness or fainting also supports avoiding repeat dosing within 24 hours.
Poxet should be swallowed whole with water unless a prescriber or dispensing pharmacist gives a specific alternative instruction. Crushing or chewing can make the tablet unpleasant to take and may alter how the dose is released or absorbed. The 2013 EMA product information describes oral tablet administration, so a higher dose should never be created by manipulating a tablet.
Poxet is intended for adult men and is not a treatment for use during pregnancy. A partner’s pregnancy does not create a direct indication for dapoxetine, but the medicine should still be used only by the person for whom it was prescribed. The NHS and MHRA guidance published in 2024 on medicines in breastfeeding emphasises checking active substances and exposure, so dapoxetine should not be used by a breastfeeding person.
Severe liver impairment is a clear reason to avoid dapoxetine. A history of syncope, significant heart disease, or treatment with MAO inhibitors also prevents use because of the risk of fainting, rhythm disturbance, or serious interaction. The 2013 EMA product information lists these restrictions as part of the medicine’s safety framework.
Do not take another tablet on the same day or increase the strength independently. The British Association for Sexual Health and HIV guidance published in 2024 supports reassessing the diagnosis, erection quality, anxiety, medication interactions, and relationship factors when treatment response is poor. A clinician may adjust the treatment plan, address another cause, or recommend behavioural therapy alongside medication.

The first attempt was disappointing because I had taken it too close to sex and felt slightly sick. After using it earlier and avoiding alcohol, I noticed better control by the third or fourth attempt. The dizziness was manageable, but I would not have wanted to drive afterwards.
It helped with control, and the pressure between my partner and me eased. My main problem was light-headedness when I stood up quickly. I also took it after wine once, which made the side effects much worse, so I stopped mixing the two.
The delay was useful, but the result was not the same every time. It worked better when I was relaxed and had slept properly. Nausea appeared after the higher dose, so I went back to the lower strength after discussing it with my prescriber.
