Poxet (Dapoxetine) — Patient Information for the United Kingdom

Poxet contains dapoxetine, a medicine used to treat premature ejaculation in adult men. This page explains what Poxet is, how it works, how to take it safely, and what to expect. It is written for patient understanding in the UK.

Key information at a glance

• What it’s for: Treatment of premature ejaculation (PE) in men.
• How it works: Helps reduce overactivity of serotonin signalling, which can improve control and delay ejaculation.
• How it’s taken: Usually on-demand (a dose taken before sex), according to a personalised schedule.
• Timing matters: Often taken 1–3 hours before sex (your prescriber/pharmacist may advise a specific timing).
• Common side effects: Nausea, dizziness, headache, diarrhoea, and fatigue.
• Important safety note: Avoid combining with certain medicines that affect serotonin or those that can interact with dapoxetine. Do not mix with recreational drugs that affect serotonin.
• Alcohol: Alcohol may increase the risk of side effects such as dizziness and fainting.

Basic product information

What is premature ejaculation?

Premature ejaculation is commonly described as ejaculation that occurs sooner than desired, often with limited control. It can be lifelong or acquired. Poxet is intended to help improve ejaculation control and reduce distress associated with PE.

How Poxet works (mechanism of action)

Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) with a rapid onset. It increases serotonin levels in the brain by blocking the reuptake of serotonin at nerve terminals. Serotonin is involved in sexual function and reflexes.

By enhancing serotonin signalling, dapoxetine can help:

• Increase control over ejaculation
• Delay ejaculation during sexual activity
• Reduce the sense of urgency that can accompany PE

Pharmacokinetics — how the body processes it

Pharmacokinetics describes what the body does to a medicine, including absorption, distribution, metabolism, and elimination.

• Absorption: Dapoxetine is absorbed after oral dosing. Peak levels in the blood typically occur within a few hours.
• Onset of effect: Because it is taken before sex, the timing of dosing is important. Many people see effects within the recommended dosing window.
• Distribution: The medicine is distributed throughout the body, including the central nervous system.
• Metabolism: Dapoxetine is primarily metabolised in the liver (notably by CYP enzymes).
• Elimination: Metabolites are cleared from the body mainly via the kidneys and bile.

Why this matters: People with liver problems or those taking medicines that strongly inhibit or induce metabolism may have higher or lower blood levels, increasing the risk of side effects or reducing effectiveness.

Typical use and indications in the UK

Poxet (dapoxetine) is indicated in adult men for the treatment of premature ejaculation.

It is intended for men who experience:

• Frequent premature ejaculation with distress
• Limited control over ejaculation timing

Poxet is not a treatment for erectile dysfunction by itself (though sexual function may improve indirectly if PE symptoms reduce anxiety and stress).

How to take Poxet — dosing and timing

Always follow the dosing instructions provided with your medicine. Your dose may be adjusted based on side effects and tolerability.

Typical on-demand schedule

• When to take it: Usually 1–3 hours before sex.
• Frequency: Do not exceed the maximum recommended dosing frequency.
• First few doses: Many people start at a lower dose to assess tolerability.

Starting and dose adjustment (general guidance)

In practice, dapoxetine regimens often begin with a lower strength and are then increased if tolerated, or reduced if side effects occur. Your healthcare professional/pharmacist may advise the specific starting strength and maximum dose for you.

Missed dose

Poxet is used on-demand. If you do not take a dose before planned sex, do not take it “after the fact”. Use the next dose only when appropriately timed for future sexual activity, within the maximum frequency limits.

Special populations

• Older adults: Increased sensitivity to adverse effects is possible.
• Liver impairment: Dapoxetine may be avoided or used with caution depending on severity.
• Kidney impairment: Dose adjustments may be needed for safety and tolerability.

Timing tips — getting the best out of your dose

• Plan ahead: Take it in advance so it can reach peak levels during sex.
• Consistency helps: If you notice effects are either too early or too late, discuss timing changes with a healthcare professional.
• Avoid “stacking doses”: Do not take extra tablets to compensate for timing.
• Hydration and rest: Feeling dehydrated or tired may make side effects like dizziness more likely.

Food interactions — can you take Poxet with meals?

Food can affect how quickly medicines are absorbed. For dapoxetine, taking it with food may change the timing of peak levels (for example, absorption may be slower with a heavy meal). The key practical point is:

• Follow the instructions supplied with your medicine.
• If you consistently take it at the same time relative to meals, you may find the effect becomes more predictable.

Practical guidance: If you’re sensitive to side effects, some people find taking Poxet with or after a light snack is easier than taking it on an empty stomach. However, any change should be within the labelling guidance and discussed if you have concerns.

Alcohol and medicine interactions

Alcohol

Alcohol can increase the risk of:

• Dizziness or light-headedness
• Fainting (syncope)
• Other common side effects such as nausea

Recommendation: Avoid or minimise alcohol on the day you take Poxet, particularly before sex.

Other medicines that may interact

Dapoxetine is processed by liver enzymes and affects serotonin pathways. Certain medicines can increase dapoxetine levels or increase serotonin-related side effects.

Avoid combining with (examples):

• Monoamine oxidase inhibitors (MAOIs)
• Other serotonergic medicines (e.g., certain antidepressants or migraine medicines acting on serotonin)
• Strong inhibitors of specific liver enzymes (which can raise dapoxetine exposure)

Be cautious and seek advice before use if you take:

• Medicines that affect serotonin (SSRIs, SNRIs, tricyclic antidepressants, MAOIs, St John’s wort)
• Medicines for mood disorders (because of serotonin syndrome risk)
• Medicines for blood pressure or those that cause orthostatic hypotension (due to dizziness risk)
• Anticoagulants/antiplatelets (serotonin medicines can rarely increase bleeding risk—your pharmacist can advise)

Recreational drugs

Avoid combining dapoxetine with recreational substances that affect serotonin (for example, some “party drugs”), as this can increase the risk of serious adverse reactions.

Safety profile — who should be extra careful?

Poxet is generally well tolerated when used correctly, but it can cause side effects, especially during the first doses. Some reactions require urgent medical attention.

Common side effects

• Nausea
• Dizziness
• Headache
• Diarrhoea
• Fatigue
• Sleepiness or reduced alertness

Less common but important risks

• Fainting (syncope): Can occur, particularly with dizziness. Sit or lie down if you feel light-headed.
• Falls due to dizziness
• Serotonin syndrome: A rare but potentially serious reaction if combined with other serotonergic medicines.

Symptoms that need urgent medical attention

Seek urgent help if you experience signs of serotonin syndrome or severe allergic reaction, such as:

• High fever, severe agitation, confusion
• Fast heart rate, sweating, tremor
• Severe diarrhoea or vomiting
• Muscle stiffness or jerking
• Swelling of the face/lips, difficulty breathing, or widespread rash

When not to use Poxet

Do not use Poxet if you have contraindications outlined in the medicine’s safety information, including certain:

• Severe heart rhythm or cardiac conditions
• Significant liver impairment
• Current use of medicines that strongly interact with dapoxetine or serotonergic pathways
• History of fainting or significant orthostatic symptoms may require extra caution

Because suitability depends on your individual health and medicines: If you are unsure, speak to a qualified healthcare professional before starting.

Practical use tips for safer, more comfortable dosing

• Take your first dose when you can rest: It’s often best on an evening when you’re not driving and can be near a bathroom if nausea occurs.
• Stand up slowly: If dizziness happens, take your time when standing.
• Do not drive if you feel dizzy or drowsy.
• Keep a note of timing and effects: Track when you took it, how long until you noticed an effect, and any side effects.
• Use only as directed: Avoid exceeding the maximum frequency.
• Watch for interaction symptoms: If you feel unusually unwell after starting or changing medicines, stop and seek advice promptly.

How effective is Poxet?

Effectiveness varies between individuals. Many people notice improvement after regular on-demand use over time. If you do not see benefit or side effects are problematic, your clinician/pharmacist may consider a different treatment approach.

Note: PE symptoms are influenced by anxiety, relationship factors, and sexual health conditions. Managing stress and considering behavioural strategies can complement medication.

Alternative options for premature ejaculation

If Poxet is not suitable, not tolerated, or not sufficiently effective, other options may be considered:

Behavioural approaches

• Start–stop technique
• Squeeze technique
• Mindfulness and performance anxiety management

Other medicines

• Topical anaesthetics (numbing sprays/creams) — may help reduce sensitivity
• Other oral treatments sometimes used off-label in PE depending on clinical assessment

Specialist support

Some people benefit from referral to a GP with a special interest in sexual health or to a urologist/andrologist, particularly if PE is severe, lifelong, or linked to other sexual or psychological factors.
