BOSTON (AP) - Two research reports suggest a possible link between two bone-building drugs and irregular heart rhythms in a small number of women who take the medicine.
The signs of a problem were more pronounced with Reclast, a drug made by Novartis AG and given through a once-a-year, 15-minute intravenous infusion. But there was a hint of similar trouble in a few women who took the leading osteoporosis pill, Fosamax by Merck & Co. The two drugs are in the same class.
The safety question caught researchers by surprise. While uncertain how big a worry it might be, they agreed the overall risk is small. Specialists said women at high risk for bone breaks — the main target of these osteoporosis drugs — should keep taking them as prescribed.
