Vioxx (Rofecoxib) is a prescription nonsteroidal anti-inflammatory drug. It is manufactured by Merck & Co. and was approved by the Food and Drug Administration in 1999. It is intended to treat osteoarthritis, menstrual cramps, rheumatoid arthritis, and other causes of acute pain. However, serious concerns have been raised over the safety of this drug, particularly the increased risk of heart attack, stroke, and other serious cardiovascular events. On September 30, 2004, Vioxx was recalled by Merck & Co. after a medical study found that patients taking the drug had a higher rate of heart attacks and strokes than those on a placebo. If you have suffered serious medical side effects after taking Vioxx, you may be eligible to participate in a lawsuit. Victims of heart attack and stroke may be able to recover compensation for the damages they have suffered.
