Fosamax is the most widely used treatment for osteoporosis. But new research suggests Fosamax could increase the risk for heart rhythm disturbances.
Researchers compared a group of women with hearts that beat irregularly with women who had no heart trouble. Those who used Fosamax were nearly twice as likely to have atrial fibrillation.
Scientists stress more research needs to be done.
This study is in the Archives of Internal Medicine.
