Vardenafil is used to treat male sexual problems that result in impotence or erectile dysfunction(ED). Patients suffering from an erectile dysfunction are unable to get or keep an erection steady enough to engage in a sexual intercourse. ED can be experienced due to age, stress, depression or other health conditions that may need treatment. It can also be due to relationship problems. Vardenafil increases the blood flow into the penis which helps you to achieve and maintain an erection for a longer period.
