We reported on Byetta (exenatide) in August 2008, when the FDA issued a MedWatch email alert about six new cases of hemorrhagic pancreatitis and necrotizing pancreatitis that had been reported to FDA since an October 2007 “Dear Doctor” letter about Byetta and acute pancreatitis was sent to doctors in the U.S.
The March 2009 Drug Safety Update newsletter — from drug regulators in the United Kingdom (UK) — included this article, “Exenatide (Byetta): risk of severe pancreatitis and renal failure”. We get some new information about two types of serious side effects associated with Byetta, pancreatitis and renal, or kidney, impairment.
