GlaxoSmithKline's Avandia diabetes drug has had so many bad marks against it recently that it's amazing anyone is still buying it. Well, here's another.

In a recent report, the diabetes drug sold by prescription was linked with an increase in osteoporosis risk after being connected to increased heart disease risk this summer.

The newer study did admit that the osteoporosis finding was indeed a slight mistake, and it was surprised that earlier studies had not connected the use of Avandia with osteoporosis. For those who are older and at risk of fractures already, the taking of Avandia should be discussed with your doctor at length.
