Dapoxetine is mainly used to treat men with severe premature ejaculation. It is an inhibitor of 5-hydroxytryptamine reuptake in the brain and can delay the stimulation of sexual impulses. It can be taken orally 30 minutes before sexual intercourse, and the effect can be maintained for 2-3 hours after the drug is administered, but the specific effect after application is not exactly the same for each patient. The efficiency of Dapoxetine Hydrochloride is above 98% and can prolong sex for more than half an hour, so patients should take it orally if they need it to clarify the specific effectiveness and duration of the drug. Sometimes patients have more local penile dorsal nerves in the glans, and in this case oral dapoxetine hydrochloride is not effective. Before treating premature ejaculation, you can test the glans sensitivity to clarify whether the glans is overly sensitive, and then choose the right symptomatic treatment.
