Poxet 90 mg is not primarily used for achieving a solid erection. Instead, it is a medication used to treat premature ejaculation (PE) in men. Premature ejaculation is a common sexual disorder where a man ejaculates too quickly during sexual activity, often before he or his partner would like. Poxet 90 mg is specifically designed to help men with PE by extending the time it takes to reach ejaculation.
