ABSTRACT
Exenatide is a glucagon-like peptide-1 receptor agonist that is commonly used in the treatment of type II diabetes mellitus for its effects on the incretin system. The use of exenatide is also related to weight loss and it has reportedly been known to induce acute renal failure (ARF) according to clinical reports. We observed ARF and severe weight loss two months after beginning the treatment with exenatide in a 59-year-old female patient with type II diabetes mellitus. We present this case in which ARF was considered to be a rare adverse effect of exenatide use. In conclusion, renal functions should be closely monitored, especially in patients prescribed nephrotoxic agents and for those with a high risk of nephropathy and dehydration due to their treatment with exenatide. The usage of this drug should also be carefully planned in these patients.
