I have attached a copy of something written by my friend Mark Clifford and posted on his web Page. His short blog does a great job describing the primary side effects of of glitazones , ACTOS( pioglitazone) and Avandia ( rosiglitazone) .
Click on his title below and it will link you to his web site.
