Abstract

Abstract Disclosure: K. Rao: None. E. Kyei Nimako: None. Mounjaro : A Side Effect Dr K Rao, Dr Evans-Nimako, Internal Medicine, North Alabama Medical Center Introduction: Mounjaro has been heralded as a new miracle drug both in the world of diabetes management and weight loss with its pending FDA approval in the latter category. Although common contraindications are known the wider spectrum and prevalence of side effects including diabetic retinopathy, acute kidney injury and gallbladder disease are still being identified. In this case we present a patient with Mounjaro induced AKI and ileus. Case Presentation: We present the case of a 64year-old diabetic, hypertensive male presenting with a 3-day history of nausea vomiting indigestion and excessive burping one day after taking his first dose of Mounjaro. The Patient was started at a walk-in clinic on 2.5 mg subcutaneously however on the very next day he noticed the onset of cramping abdominal pain with multiple episodes of vomiting and watery diarrhea. The patient has not had any other new foods, sick contacts or preceding illnesses. He had a history of previous hernia surgery, cholecystectomy and exploratory laparotomy some 18 years ago due to concerns for nonresolving small bowel obstruction. On examination he was afebrile but tachycardic and in mild distress. His abdomen was soft and nondistended. Bowel sounds were faint but present. He had generalized tenderness without evidence of rebound or guarding. Initial investigations demonstrated a white cell count of 14.7(10E3/ul), creatinine 1.7mg/dl, potassium 4.5mmol/L, blood glucose 176mg/dl and lactate of 2mmol/L. His urine analysis showed small volume ketones, glucosuria and trace leukocyte esterase with 3-5 white blood cells. CT of the abdomen and pelvis with contrast showed distended small and large bowel loops with fluid air levels but no transition point indicative of underlying ileus. The patient was hospitalized in total for approximately six days post the onset of his symptoms and treated with supportive measures including antiemetics, IV fluids and antacids. He never had any fevers or leukocytosis during his stay. His electrolytes remained within normal limits. Conclusion: Due to the impending widespread use and increasing popularity of Mounjaro this case presentation is aimed at raising awareness of potential side effects and their severity. We also hope to contribute towards further knowledge about specific subset of patients who may be more susceptible to the gastrointestinal side effects of Mounjaro. Particularly those patients who have had previous colonic or multiple abdominal surgeries or history of bowel obstruction. In this case the patient received the medication at a walk-in clinic this also highlights the dangers of lack of established care and monitoring of Mounjaro. Presentation: Saturday, June 17, 2023
