Levitra

vardenafil

Levitra is manufactured and marketed by Bayer AG. In May 2005, Levitra was linked to one additional case of nonarteritic ischemic optic neuropathy (NAION), a “stroke of the eye” that occurs when blood flow is restricted to the optic nerve, causing partial or total loss of vision. While some vision loss has been mild, NAION is a permanent, irreversible condition. Cialis was also linked to four additional case of NAION.

Those most at risk for NAION while taking erectile dysfunction drugs are patients older than 50 who also have the following conditions:

• Diabetes
• High blood pressure
• Heart disease
• High cholesterol

In October 2007, the United States Food and Drug Administration (FDA) mandated label changes on erectile dysfunction (ED) drugs, including Levitra, to include the potential risk of sudden hearing loss.
