Sildenafil Label and Vision Loss
Pfizer has agreed to change the label for Viagra® (sildenafil tablet), its medication for erectile dysfunction, to warn doctors about sudden vision loss in some men who took the drug.
The FDA is asking all makers of impotence drugs to include similar warnings. No “causal relationship” has been made between Viagra® and the condition, a type of eye stroke called non-arteritic anterior ischemic optic neuropathy, Pfizer said.
Pfizer released its statement before a CBS News report that examined four years of FDA data on complications among Generic Viagra users. The analysis found 800 reports of eye problems, including 140 cases of partial or total blindness, CBS said. Pfizer said its own review found no evidence of increased risk of blindness in men taking the drug.
