Worried about prescription drugs? How to weigh your risk?

When the pain reliever Vioxx was withdrawn from the worldwide market last September after the announcement that it increased patients' risk of heart attacks and strokes, millions panicked. Suddenly, ads for the drug were replaced with ads looking for Vioxx “victims”. Not only did patients stop taking Vioxx but, doctors say, many people stopped taking their other medicines, too --- sometimes putting their health at serious risk.
