LAWSUIT ALLEGING BLINDNESS FROM TAKING VIAGRA IS FILED IN TEXAS FEDERAL COURT

A federal lawsuit filed by James Thompson in the United States District Court for the Southern District of Texas seeks monetary damages for the loss of vision allegedly caused by the use of Viagra, Pfizerís blockbuster erectile dysfunction (ED) drug. Mr. Thompson also seeks class- action certification on behalf of all other men injured by the drug.

The Food and Drug Administration has received over 40 reports of blindness in men taking Viagra, Levitra, or Cialis. This type of irreversible blindness known as non-arteritic anterior ischemic optic neuropathy (NAION) restricts the flow of oxygenated blood to the optic nerve.

Pfizer has taken the position that its drug does not cause NAION and that a class-action is inappropriate. The company claims that NAION shares a number of common risk factors with ED, including high blood pressure, diabetes, and high cholesterol.

The lawsuit charges that Pfizer failed to warn the public that taking Viagra could cause NAION.
