Poxet is a brand-name medication that contains dapoxetine as its sole active ingredient. Dapoxetine belongs to the short-acting selective serotonin reuptake inhibitor (SSRI) class and is used to treat premature ejaculation in adult men. The product is supplied as a pill and is available in three strengths: 30 mg, 60 mg, and 90 mg. In Hong Kong, dapoxetine-containing medicines are classified as prescription-only drugs and are regulated by the Department of Health’s Pharmacy and Poisons Board.
Dapoxetine works by inhibiting the reuptake of serotonin at nerve terminals in the central nervous system. This increases the amount of serotonin available in the synaptic cleft, which enhances the inhibitory control over the ejaculatory reflex. The drug reaches peak plasma concentrations within about 1-2 hours after ingestion, making it suitable for on-demand use (taken 1-3 hours before sexual activity). Its relatively short half-life (approximately 1.5 hours) means the drug’s effects dissipate quickly, reducing the risk of prolonged serotonergic exposure.
In Hong Kong, as in many jurisdictions, dapoxetine is the only medication formally approved for the treatment of premature ejaculation (PE). Clinical trials have demonstrated that dapoxetine can increase the intravaginal ejaculatory latency time (IELT) by several minutes compared with placebo, providing men with better control over ejaculation. The medication is intended for adult males who experience PE at least once weekly and for whom behavioral techniques alone have not provided sufficient relief.
Current peer-reviewed literature does not support any off-label indications for dapoxetine that are widely accepted in clinical practice. Some small studies have explored its use in female sexual dysfunction and social anxiety, but these investigations are preliminary and the drug is not approved for these conditions.
Disclaimer: Off-label use of any medication requires direct supervision by a qualified healthcare professional, and the potential benefits must be weighed against unknown risks.
Major interactions (avoid co-administration):
MAO inhibitors (e.g., phenelzine, tranylcypromine) - risk of serotonin syndrome
Other SSRIs or SNRIs (e.g., sertraline, venlafaxine) - additive serotonergic effect
Moderate interactions (requires monitoring or dose adjustment):
CYP2D6 inhibitors (e.g., fluoxetine, paroxetine) - may increase dapoxetine plasma levels
Tramadol - potentiates serotonergic activity
Anticoagulants (e.g., warfarin) - occasional reports of altered bleeding risk; monitor INR
If you are taking any other medicines, supplements, or herbal products, inform your healthcare provider before starting Poxet.

Poxet may be taken with a moderate amount of alcohol, but excessive drinking can increase dizziness and headache. If you notice intensified side effects, it is advisable to limit alcohol intake when using the medication.
The recommended window is 1 to 3 hours before sexual activity. Taking it earlier may reduce its effectiveness, while taking it later may not provide sufficient therapeutic coverage.
Poxet tablets are typically round, white to off-white, and may bear a imprint or brand logo specific to the manufacturer. The exact appearance can vary between markets.
Yes. Dapoxetine-containing products, including Poxet, are classified as prescription-only medicines and must be prescribed by a licensed physician in Hong Kong.
There is limited scientific evidence supporting the use of dapoxetine for conditions other than premature ejaculation. Off-label use for other sexual dysfunctions is not approved and should only be considered under specialist supervision.
If the planned sexual activity is still more than 3 hours away, simply skip the missed dose and take the next dose as scheduled. Do not double the dose to make up for the missed one.
Dapoxetine does not interfere with hormonal contraceptives. However, it is not intended for use in women, and pregnancy is a contraindication.
No specific foods need to be avoided, but taking the pill with a light snack or water is recommended to improve absorption. High-fat meals may delay the onset of action slightly.
Poxet (dapoxetine) has a short half-life, allowing on-demand dosing for sexual activity, whereas traditional SSRIs are taken daily and have longer durations of action, making them unsuitable for this specific use case.
