I’m usually one to pee on the parade of such reports. They’re usually made up of first class bovine excretion. Even the FDA is saying it’s nothing new…
"There is no evidence showing that NAION occurred more frequently in men taking Viagra than men of similar age and health who did not take Viagra," Pfizer said in a statement.
The FDA's Cruzan said NAOIN is not uncommon for people of the age that use the impotence drugs, who have conditions like heart conditions, diabetes and heart disease. It also occurs in patients who have not taken Viagra.
… but I’m inclined to wait and see on this one, if for no other reason than the aggravation being hit with ads for the stuff at every stopset on both TV and radio.
