Vardenafil is a new treatment for erectile dysfunction in men. It works in a similar way to other preparations such as Sildenafil (ViagraR) or taldenafil (CialisR).
Erectile dysfunction (ED) is a term used for difficulty in getting or sustaining an erection. This is described in a separate leaflet.
Erections are controlled by two main chemicals in the body. One of these chemicals helps produce and erection. The second takes it away. If these two chemicals are out of balance the mechanism of erection fails. Levitra works by reducing the action of the second chemical called PDE-5, which is reponsible for ending an erection. This allows an erection to last long enough to complete intercourse.
You need to take Levitra about half to one hour before sexual activity. It will only work when you are sexually stimulated.
Taking Levitra after a heavy meal may delay the effect. You may take the tablet with or without food
Levitra may make you feel dizzy or effect your vision. If this happens do not drive or use machinery.
Your doctor will prescribe a suitable dose.
The tablet is available in 3 different strengths - 5mg, 10 mg and 20 mg. Swallow one tablet with a glass of water.

Less commonly the following effects may be encountered.
Do not use Levitra more than once a day.
