General Info:

Levitra relaxes muscles and increases blood flow to particular areas of the body. Levitra is used to treat erectile dysfunction (impotence).

A small number of patients have had a sudden loss of eyesight after taking Levitra. This type of vision loss is caused by decreased blood flow to the optic nerve of the eye. It is not clear whether Levitra is the actual cause of such vision loss. Sudden vision loss with Levitra use has occurred most often in people with heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old.

Do not take Levitra if you are also using a nitrate drug for chest pain or heart problems.

Levitra is usually taken only when needed, up to 60 minutes before sexual activity. The medication can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor's instructions. Do not take Levitra more than once a day. Allow 24 hours to pass between doses.
