Levitra Side Effects Injury Lawsuits. On August 19, 2003 , The Food and Drug Administration (FDA) approved Levitra (Generic: Vardenafil hydrochloride), an oral medication to treat erectile dysfunction (ED, or impotence) in men.
Federal health officials are investigating rare reports of blindness among men using Levitra. The Food and Drug Administration is aware of 1 report of varying degrees of vision loss, including blindness, associated with Levitra.
NAION Is The Most Common Causes of Sudden Vision Loss
At issue is NAION, or Non-Arteritic Anterior Ischemic Optic Neuropathy, which causes sudden vision loss when blood flow to the optic nerve is blocked. NAION is considered one of the most common causes of sudden vision loss in older Americans.
Estimates suggest there are anywhere from 1,000 to 6,000 NAION cases a year. Risk factors include diabetes and heart disease, two of the leading causes of impotence. The routine NAION cases plus overlapping risk factors means it may be impossible for FDA to tease out whether the drugs really increase risk for this eye problem. Erectile dysfunction (ED) affects more than 30 million men in the United States. Its risk factors are similar to those for atherosclerotic heart disease.
