Common uses
Levitra is an oral therapy for the treatment of erectile dysfunction (ED). ED is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. A man who has trouble getting or keeping an erection should see his doctor for help if the condition bothers him. Levitra may help a man with ED get and keep an erection when he is sexually excited.
Levitra helps increase blood flow to the penis and may help men with ED get and keep an erection satisfactory for sexual activity. Once a man has completed sexual activity, blood flow to his penis decreases and his erection goes away.
