Dapoxetine is primarily used in the treatment of premature ejaculation (PE) in men. It works by increasing the time it takes to ejaculate, thereby improving control over ejaculation and reducing distress related to the condition. It is typically taken as an on-demand medication, usually 1 to 3 hours before anticipated sexual activity. The drug helps enhance sexual satisfaction for both partners by prolonging the duration of intercourse. It is often prescribed alongside psychological counseling or behavioral techniques to address the underlying causes of PE. Dapoxetine is not intended for daily use and should be taken only when needed, as directed by a healthcare professional.
