Dapoxetine hydrochloride is primarily used in the treatment of premature ejaculation in adult men. It works by increasing the time it takes to ejaculate, thereby improving control over ejaculation and reducing distress related to the condition. The medication is taken orally, usually 1 to 3 hours before anticipated sexual activity, and its effects are temporary, making it suitable for on-demand use. It is often prescribed as part of a broader approach that may include psychological counseling or behavioral techniques to address the underlying causes of premature ejaculation. Patients are advised to follow their healthcare provider's instructions carefully to minimize potential side effects and ensure optimal results.
