Actos and Avandia, diabetes drugs also known as TZDs have been definitively linked to an increased risk of broken bones according to a new study from the Journal of Clinical Endocrinology & Metabolism. This past summer an FDA panel of experts voted to put new warning labels on Avandia because of its link to heart problems. Post-menopausal women over 50 were found to be most susceptible to bone fractures, with 71% of those who suffered fractures found to be taking Avandia or Actos. Men also experienced fractures while taking a TZD combined with a loop diuretic often prescribed to diabetes sufferers.
