NPR's Jon Hamilton reports on the controversy surrounding a drug widely used by diabetics. FDA advisers meet in Maryland today to discuss Rezulin, which was a big-seller when it came out in 1997 because it enabled many diabetics to reduce their need for insulin injections. But now there is serious concern that the drug significantly increases the risk of liver failure. Some are calling for a ban on the drug but others say that even with the risk of side effects, the benefits of Rezulin outweigh the potential harm.
