Studies finding diabetes drugs not necessarily safe

In my subscriptions the following link to an article I received really got my attention. Three studies have just recently cast lots of doubt about the safety of the diabetes drugs that are among the most prescribed.
The link is: http://www.healthcentral.com/diabetes/c/17/67852/diabetes-dangers .

I know that my doctor is getting a call tomorrow.

Thanks for this, Robert. I was glad to see that I’m on a fairly “safe” regimen - metformin and lantus (long-acting insulin) - AND, most importantly, low-carb diet. Actos nearly killed me - fortunately, I was only on it for 2 months. I didn’t see anything about sulfonylureas?, which I took for years before learning the downfalls of that.
