Impotence Drugs Under Attack

"CBS News correspondent Sharyl Attkisson reports that two reasons fueled Public Citizen's FDA request. First, studies show that people don't pay much attention to the type of warning that was added in July. They do pay attention to a Black Box warning, which is what Public Citizen is pushing for.

"Second, Attkisson adds, there's new information. Pfizer had claimed men weren't more likely to go blind if they take Viagra. But Public Citizen says in men with similar risk factors, Viagra users are much more likely to suffer a type of eye stroke called 'NAION.' And it's not just a question of eye stroke but other types of blindness." [CBS News]
