Information About Levitra

Warnings: There have been rare reports of prolonged erections greater than 4 hours and priapism (painful erections greater than 6 hours in duration) for this class of compounds, including vardenafil. In the event that an erection persists longer than 4 hours, the patient should seek immediate medical assistance. If priapism is not treated immediately, penile tissue damage and permanent loss of potency may result.

In humans, vardenafil alone in doses up to 20mg does not prolong the bleeding time. There is no clinical evidence of any additivee prolongation of the bleeding time when vardenafil is administered with aspirin. Vardenafil has not been administered to patients with the bleeding disorders or significant active peptic ulceration. Therefore Levitra should be administered to these patients after careful benefit-risk assessment. Treatment for erectile dysfunction should generally be used with caution by patients with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease) or by patients who have conditions that may predispose them to priapism (such as sickle cell anemia, multiple myeloma, or leukemia).

Other side effects are headaches, flushing, stuffy or runny nose, indigestion, upset stomache, or dizziness. These side effects usually go away after a few hours. Call your doctor if you get a side effect that bothers you or one that will not go away.

Levitra may uncommonly cause:

An erection that won't go away (priapism). If you get an erection that lasts more than 4 hours, get medical help right away. Priapism must be treated as soon as possible or lasting damage can happen to your penis including the inability to have erections.

Vision changes such as seeing a blue tinge to objects or having difficulty telling the difference between the colors blue and green.

The use of Levitra offers no protection against sexually transmitted diseases. Counseling of patients about protective measures necessary to guard against sexually transmitted diseases, including the human immunodeficiency virus HIV should be considered.
