Poxet (Dapoxetine) – Patient Guide (United Kingdom)

Poxet is a medicine containing dapoxetine, used to treat premature ejaculation in adult men. It works by affecting serotonin pathways in the brain to help increase control over ejaculation and delay it. This page explains how Poxet works, how it is taken, what to expect, and the key safety information you should know before use.

The information below is intended to be patient-friendly and practical. It does not replace the advice of a healthcare professional, and you should always read the patient information leaflet supplied with your medicine.

Quick facts

• Medicine name: Poxet
• Active ingredient: Dapoxetine
• What it treats: Premature ejaculation
• How it’s taken: Usually as an on-demand tablet before sexual activity
• Common effects you may notice: Increased time to ejaculation, improved control
• How often: Up to once per day (details below)

Basic product information

What is premature ejaculation?

Premature ejaculation (PE) is a common sexual problem where ejaculation happens sooner than desired, often with limited ability to delay it. It can cause distress and relationship strain. Dapoxetine is specifically indicated for PE and aims to improve control and delay ejaculation.

Mechanism of action (how Poxet works)

Dapoxetine is a medicine that affects serotonin signalling in the brain. In simple terms, it is a selective serotonin reuptake inhibitor (SSRI). By inhibiting serotonin reuptake, it increases serotonin activity in certain pathways involved in sexual reflexes and ejaculation timing.

The result is improved control over ejaculation and an increase in the time between sexual stimulation and ejaculation for many men.

Pharmacokinetics (how the body handles dapoxetine)

“Pharmacokinetics” describes absorption, distribution, metabolism, and elimination.

• Absorption: Dapoxetine is absorbed after oral dosing. On-demand use is designed for activity before sexual intercourse.
• Time to effect: Many people take it shortly before sex, following the recommended timing to achieve appropriate blood levels.
• Distribution: Dapoxetine distributes throughout the body, including the central nervous system.
• Metabolism: It is mainly processed by the liver (notably through CYP enzymes).
• Elimination: Dapoxetine and its metabolites are removed from the body, primarily via metabolic clearance.

Your healthcare professional may adjust or avoid dapoxetine based on factors such as liver health, other medicines, and your risk of side effects like dizziness or fainting.

Typical use and indications

Indication in the UK

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

It is generally intended for men who want an on-demand treatment rather than continuous daily dosing.

Who may not be suitable

Poxet may not be suitable for everyone. You should take particular care if you:

• Have a history of fainting or significant dizziness
• Have heart rhythm problems or cardiovascular instability
• Have liver impairment (dapoxetine is processed by the liver)
• Take medicines that significantly affect serotonin or drug metabolism
• Have experienced serious mental health reactions with antidepressants or serotonergic medicines

Dosing in adults: how to take Poxet

Dosing must follow the product’s instructions and your prescriber’s advice. The exact dose can vary depending on tolerability and safety.

Common on-demand dosing approach

• Take when needed: Typically taken shortly before sexual activity.
• Use no more than once in 24 hours: Do not exceed the maximum daily frequency.
• Maximum frequency: Many schedules limit use to up to 1 dose per day.

Starting dose and adjustments

Many patients start at a lower strength to assess tolerance, then—if suitable—may be adjusted upward. Your healthcare professional will consider factors such as side effects (particularly dizziness) and overall health.

Timing before sex (practical guidance)

Dapoxetine is intended for on-demand use. A common strategy is to take the tablet 1–3 hours before sexual activity (following the instructions provided for your specific strength and product leaflet). Taking it too late may reduce effectiveness.

If you experience side effects such as dizziness, you may be advised to adjust timing, reduce the dose (if appropriate), or discontinue use.

How to take the tablet

• Swallow the tablet with water.
• Do not split or crush tablets unless the leaflet instructs you.
• Try to be well hydrated, especially if you are prone to dizziness.

Food interactions

Food may affect how quickly dapoxetine levels rise. In general, taking it with or soon after a meal may alter absorption and timing. To minimise variability, many patients aim for a consistent routine each time they take Poxet.

If the patient leaflet for your product describes specific guidance (e.g., with or without food), follow that advice.

What to do in practice

• If you notice reduced effect when taking it after heavy meals, consider taking it with a light meal or as directed by the leaflet.
• If you notice increased dizziness with certain meals, discuss options with your clinician.

Alcohol and medicine interactions

Alcohol

Alcohol can increase the risk of side effects such as dizziness, light-headedness, and fainting. For best safety, it’s generally advised to be cautious or avoid alcohol around the time you take Poxet.

If you plan to drink, use extra caution: do not take Poxet and then drink heavily. Safety is especially important if you are already prone to low blood pressure or dizziness.

Important medicine interactions

Dapoxetine interacts with medicines that influence serotonin levels and with drugs that affect liver enzymes. Some combinations can increase side effect risk or lead to unsafe levels of dapoxetine.

Examples of interaction concerns include (not exhaustive):

• MAO inhibitors (and certain related treatments): typically not used together.
• Other serotonergic medicines (e.g., some antidepressants such as SSRIs/SNRIs, triptans used for migraine, certain pain medicines with serotonergic effects): may increase the risk of serotonin-related reactions.
• Strong CYP inhibitors (medicines that slow dapoxetine breakdown): may raise dapoxetine blood levels and side effect risk.
• Medicines affecting bleeding risk (e.g., some anticoagulants/antiplatelet medicines): may increase bleeding-related risks, depending on the individual.

Tell your healthcare professional and pharmacist about all medicines you take, including:

• Prescription medicines
• Over-the-counter products (including herbal remedies)
• Recreational substances

Safety profile: side effects and when to seek help

Like all medicines, Poxet can cause side effects. Many are mild and improve with proper dose selection and timing, but some reactions require urgent medical advice.

Common side effects

• Nausea
• Headache
• Dizziness or light-headedness
• Diarrhoea
• Fatigue

Less common but important risks

• Fainting (syncope), especially in people who are prone to dizziness or have low blood pressure
• Changes in mood or anxiety/irritability (especially if you’re sensitive to antidepressant-type effects)
• Serotonin-related reactions when combined with other serotonergic medicines (seek urgent advice if severe)

Seek urgent medical help if

Contact urgent care or seek emergency help if you experience signs of a serious reaction, such as:

• Fainting or severe dizziness that doesn’t quickly pass
• Symptoms suggesting serotonin syndrome, such as high fever, confusion, severe agitation, muscle stiffness, or marked sweating
• Allergic reaction symptoms (swelling of face/lips, difficulty breathing, widespread rash)

General safety tips

• Avoid driving or operating machinery if you feel dizzy after taking Poxet.
• Stand up slowly to reduce dizziness risk.
• If you experience consistent unwanted effects, speak to a clinician about dose adjustment or alternatives.

Practical use tips to improve effectiveness and reduce side effects

The way you use Poxet can influence both tolerability and effectiveness. Consider the following practical tips:

• Plan around sleep and stress: Poor sleep and high stress can worsen dizziness and anxiety.
• Be consistent with timing: Use a similar time window before sex each time.
• Hydration helps: Being dehydrated can increase the likelihood of dizziness.
• Start cautiously: If you’re new to dapoxetine, begin at the recommended starting dose.
• Don’t stack doses: Never take an extra tablet to “make it work”.
• Track what you notice: If you get side effects, note the timing, food/drink, and dose—this helps clinicians adjust treatment.

Alternative options for premature ejaculation

Premature ejaculation can be managed with a range of approaches. Alternatives may include behavioural strategies, sex therapy, or other medicines depending on your situation and safety profile.

Non-medicine options

• Behavioural techniques (e.g., start-stop methods, squeeze techniques)
• Mindfulness and awareness training
• Sex therapy or counselling
• Condom use (may help reduce sensitivity for some people)

Other medicine options (discuss with a clinician)

Depending on local guidance and individual suitability, other pharmacological treatments may be considered. Availability and appropriateness vary, and some medicines may be used off-label in certain settings—always confirm the plan with a healthcare professional.
