Actos and Blindness

I have been writing a lot lately about Actos and bladder cancer. Let’s throw one more dagger at Actos: it may cause blindness.

This claim is nothing new. An article in Opthalmology pointed out that Actos and Avandia both raise the risk of vision loss dramatically (Glitazone Use Associated with Diabetic Macular Edema Donald S. Fong. Am J OphthVolume 147, Issue 4, Pages 583-586.e1, April 2009).

Researchers presenting at the American Diabetes Association’s Annual Meeting in San Diego last week piled on, arguing that Actos and Avandia may increase the risk of macular edema in diabetics who are unable to control their blood sugar.
