On September 30, 2004, the group announced that it would immediately take Vioxx off the market because of a new long-term study that had classified side effects of the drug that had previously been neglected as serious. This study showed an almost doubled rate of cardiovascular diseases , especially heart attacks , unstable angina pectoris and strokes, compared to a placebo after 18 months . For this reason, the study had to be terminated prematurely.

The man had suffered a fatal heart attack after eight months of continuous use of the drug. After two further court cases in which it was about heart attacks resulting in death after taking the drug, the court acquitted MSD.
