According to reports published this month in the New England Journal of Medicine, Fosamax side effects could increase the risk of a serious heart problem, known as an atrial fibrillation.  The overall risk is small, but experts have indicated that caution should be used by those at risk for an atrial fibrillation and additional research is needed to evaluate the danger.

Researchers found evidence of Fosamax heart problems after re-reviewing the results of a large clinical study involving post menopausal women, which collected data over a five year period, ending in 1997.  The original trial, known as the Fracture Intervention Trial, was conducted to evaluate the effects of Fosamax on the risk of fracture.  According to the New England Journal of Medicine, the surprise finding from the data was that the risk of a serious heart rhythm problem could be 50% greater for those taking Fosamax when compared with those taking a placebo.

Merck, the maker of the popular osteoporosis treatment, has had this data for nearly 10 years, and many question why they have not conducted further research on the risk of heart problems.  Atrial fibrillation is an abnormal heart rhythm that can increase the risk of stroke.  The report indicates that 1.5 percent of women taking Fosamax experienced a serious atrial fibrillation, compared to 1 percent taking the placebo.  Further studies are expected.

The drug maker is currently facing hundreds of Fosamax lawsuits from users who suffered a rare jaw condition, known as osteonecrosis of the jaw.  Merck has been accused of minimizing the risk of this Fosamax jaw problem in an attempt to protect their profits.  Fosamax generates approximately $2 billion in annual revenues, with about 18 million Americans taking the osteoporosis drug each year.  It is possible that they have placed profits before the safety of their consumers once again by failing to properly research their product and warn of the risk of atrial fibrillation.
