1. What Levitra is and what it is used for

Levitra contains vardenafil, a member of a class of medicines called phosphodiesterase type 5 inhibitors. They are used for the treatment of erectile dysfunction in adult men, a condition which implies difficulties in getting or keeping an erection.

At least one in ten men has trouble getting or keeping an erection at some time. There may be physical or psychological causes, or a mixture of both. Whatever the cause is, due to muscle and blood vessel changes not enough blood stays in the penis to make it hard and keep it hard.

Levitra will only work when you are sexually stimulated. It reduces the action of the natural chemical in your body which makes erections go away. Levitra allows an erection to last long enough for you to satisfactorily complete sexual activity.

2. What you need to know before you take Levitra
