Poxet 90 is a medication primarily used to treat premature ejaculation in men. It contains dapoxetine hydrochloride, which belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs). The duration of its effects can vary from person to person, but generally, it is designed to help delay ejaculation and improve control over ejaculation for several hours after ingestion.

After taking Poxet 90mg, its effects typically begin within 1 to 3 hours, reaching peak levels in the bloodstream within 1 to 2 hours after ingestion. The duration of action can last for up to 4 to 6 hours, allowing individuals to have better control over their ejaculation during sexual activity.

However, it's essential to follow the prescribed dosage and instructions provided by your healthcare provider. If you have any concerns about the duration of the effects or how to use this medication effectively, I would recommend consulting with a healthcare professional for personalized advice.
