How many days does one pill of dapoxetine last?

The effect of dapoxetine usually lasts for about 24 hours after a single dose. The drug is mainly used to treat premature ejaculation in men and needs to be taken as needed 1-3 hours before sexual activity. Dapoxetine tablets are short-acting selective serotonin reuptake inhibitors with a short half-life and will not accumulate in the body for a long time.

The duration of dapoxetine's effect is related to individual metabolism rate, dose and duration of medication. For the standard dose of 30 mg, the peak blood concentration in most men occurs 1-2 hours after taking the drug, and then gradually decreases. The 60 mg dose may prolong the action time but increase the probability of adverse reactions such as dizziness and nausea. Food may delay drug absorption but does not affect overall efficacy. This drug is mainly metabolized by the liver, and patients with abnormal liver function need to adjust the dose. Repeated doses should be administered at least 24 hours apart to avoid drug accumulation.

Dapoxetine is not suitable for continuous daily use, and tolerance may develop with long-term use. Drinking and driving should be avoided while taking the medicine. Common side effects include headache, nausea and mild blood pressure fluctuations, which usually resolve spontaneously within 2-3 hours. People with a history of heart disease or taking antidepressants must use it under the guidance of a doctor. If an erection persists for more than 4 hours or a severe allergic reaction occurs, seek medical attention immediately. It is recommended to cooperate with psychological behavioral therapy to improve the problem of premature ejaculation, and to conduct regular follow-up visits to evaluate the medication plan.
