FDA Probing Possible Link Between Viagra, Blindness
Shares of Pfizer, maker of the impotence drug Viagra, sank today after federal health officials said they were investigating a relatively small number of cases in which men taking Viagra and similar drugs reported suffering from blindness or partial vision loss.
The Food and Drug Administration has received 38 reports of blindness from Viagra users and four from those taking Cialis, said FDA spokeswoman Susan Cruzan.
The agency emphasized that the reports amount to a tiny fraction of the people taking the drugs, and that the blindness might have been triggered by other health problems. An estimated 23 million people have used Viagra, according to the manufacturer.
The vision problems "also occur in people who have never taken Viagra," Cruzan said. "We will continue to evaluate [the reports] but we can say that the drug is safe and effective as labeled."
Reports of blindness and the FDA's investigation, first reported by CBS News on Thursday, sent shares of Pfizer lower on Wall Street today. Viagra shares were down more than 2% in afternoon trading on the New York Stock Exchange.
