A Novel Case of Metformin-Induced Pancreatitis in an Individual With Normal Dosing and No Underlying Chronic Kidney Disease

It is well known that most medications have side effects, and many of them have gone through years of testing with thousands of test subjects before entering the market. However, as physicians it is important to assess how patients react to the initiation of new medications not only looking for known side effects but also rare ones. Our case highlights a rare presentation of metformin-induced pancreatitis in the setting of normal renal function and appropriate dosing. We are hoping our case will create more awareness and inspire future research in exploring the pathophysiology and causes of metformin-induced pancreatitis. Moreover, we aim to make healthcare professionals mindful so that they may recognize acute pancreatitis as a side effect of metformin even in a healthy patient.
