In a huge victory for pharmaceutical giant Wyeth, a Florida appeals court on Wednesday halted a class action suit that claimed its hormone replacement drug could harm hundreds of thousands of Florida women.

A three-judge panel of the state’s 3rd District Court of Appeal unanimously held in Wyeth Inc. v. Arlene Gottlieb that the claims were not common enough for the case to move forward as a class action. Instead, women who claim they may suffer future health problems because of their use of the drug Prempro will have to file individual suits against Wyeth.
