Sildenafil 200 mg is used to treat severe erectile dysfunction (ED) in men who do not respond to lower doses. It contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penile region, helping achieve and maintain an erection during sexual activity. This high dose is typically prescribed for men with severe ED or those who have developed a tolerance to lower doses. However, 200 mg is not a standard dose and should only be taken under medical supervision, as it increases the risk of side effects such as headaches, dizziness, and priapism (prolonged erection).
