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.
The effects of Levitra last for about 4 hours. Levitra is taken only when needed, about 60 minutes before sexual activity. The medicine can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill.
This medicine usually begins to work within 60 minutes after taking it and stimulation of the penis is required. If you have any questions about the use of vardenafil, talk to your doctor.
