My question is, how much did these guys use?
US health officials are examining reports of varying degrees of blindness among a small number of men using the anti-impotence drug Viagra. The Food and Drug Administration (FDA) has identified 50 cases of the condition, which can occur in men with heart disease or diabetes.
The FDA says it has as yet found no evidence that Viagra is to blame for the condition.
Maybe not, but I have to wonder about the safety of any drug with a disclaimer advising immediate medical attention if an erection lasts for more than four hours. Hey, look, that blood is being diverted from somewhere.
