Risk of Thyroid C-cell Tumors: Counsel patients regarding the potential risk for MTC with the use of Mounjaro and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with Mounjaro. Such monitoring may increase the risk of unnecessary procedures, due to the low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin values may indicate MTC and patients with MTC usually have calcitonin values >50 ng/L. If serum calcitonin is measured and found to be elevated, the patient should be further evaluated. Patients with thyroid nodules noted on physical examination or neck imaging should also be further evaluated.
Significantly more patients achieved the ADA guideline-recommended A1C target of <7%†ǂ with Mounjaro 10 mg and 15 mg1,2
The primary endpoint was mean change in A1C from baseline at 40 weeks.

Pancreatitis ||| mounjaro-purple
Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists. Pancreatitis has been reported in Mounjaro clinical trials. Mounjaro has not been studied in patients with a prior history of pancreatitis. It is unknown if patients with a history of pancreatitis are at higher risk for development of pancreatitis on Mounjaro. Observe patients for signs and symptoms, including persistent severe abdominal pain sometimes radiating to the back, which may or may not be accompanied by vomiting. If pancreatitis is suspected, discontinue Mounjaro and initiate appropriate management.

Hypoglycemia with Concomitant Use of Insulin Secretagogues or Insulin ||| mounjaro-purple
Concomitant use with an insulin secretagogue (e.g., sulfonylurea) or insulin may increase the risk of hypoglycemia, including severe hypoglycemia. The risk of hypoglycemia may be lowered by reducing the dose of sulfonylurea (or other concomitantly administered insulin secretagogue) or insulin. Inform patients using these concomitant medications of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.

Acute Kidney Injury ||| mounjaro-purple
Mounjaro has been associated with gastrointestinal adverse reactions, which include nausea, vomiting, and diarrhea. These events may lead to dehydration, which if severe could cause acute kidney injury. In patients treated with GLP-1 receptor agonists, there have been postmarketing reports of acute kidney injury and worsening of chronic renal failure, sometimes requiring hemodialysis. Some of these events have been reported in patients without known underlying renal disease. A majority of reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration. Monitor renal function when initiating or escalating doses of Mounjaro in patients with renal impairment reporting severe adverse gastrointestinal reactions.
Severe Gastrointestinal Adverse Reactions ||| mounjaro-purple
Use of Mounjaro has been associated with gastrointestinal adverse reactions, sometimes severe.

Drug Interactions ||| mounjaro-purple
When initiating Mounjaro, consider reducing the dose of concomitantly administered insulin secretagogues (such as sulfonylureas) or insulin to reduce the risk of hypoglycemia. Mounjaro delays gastric emptying, and thereby has the potential to impact the absorption of concomitantly administered oral medications, so caution should be exercised.

- Patients were ≥18 years of age on index date, had evidence of T2D diagnosis, had ≥1 pharmacy claim for Mounjaro or Ozempic from 13 May 2022 to 29 May 2023, had continuous enrollment during a 6-month pre-index and 12-month post-index period; and had no claims for other forms of diabetes during the 6-month pre-index period, no claims for bariatric or other procedures for obesity during the full pre-index period and 12-month post-index period, and had no claims for pregnancy, labor, and delivery in the 6-month pre index and 12-month post-index period
- Primary outcome was change in A1C and weight at 12 months of follow-up. Secondary outcomes were percent change in weight, proportion of patients with A1C ≤6.5%, proportion of patients with A1C <5.7%, cost per responder with A1C ≤6.5%, and proportion of patients adherent to medication at 12 months of follow-up
- Patients were stratified according to prior use of oral or injectable GLP-1 RAs in the 6-month pre-index period and then matched using propensity score adjustment. Patients were included in the analyses of A1C and weight if they had ≥1 valid A1C or weight value during the baseline and outcome assessment periods. Missing values were not imputed. Analyses were performed on patients with non-missing data. Doses of Mounjaro (2.5 mg to 15 mg) were pooled and doses of Ozempic (0.25 mg to 2 mg) were pooled for analysis. Changes in A1C and weight were assessed from baseline (90 days before to 14 days after index) to follow-up (index + 320 days to index + 410 days)
- At 12 months, for patients with no evidence of GLP-1 RA use in the prior 6 months, the use of Mounjaro for all eligible patients was 2.5 mg: 2%, 5 mg: 7%, 7.5 mg: 9%, 10 mg: 7%, 12.5 mg: 5%, 15 mg: 5%, and no fill: 66%, and the use of Ozempic for all eligible patients was 0.5 mg: 3%, 1 mg: 7%, 2 mg: 5%, and no fill: 84%
- At 12 months, for patients with previous GLP-1 RA use, the use of Mounjaro for all eligible patients was 2.5 mg: 1%, 5 mg: 5%, 7.5 mg: 8%, 10 mg: 8%, 12.5 mg: 6%, 15 mg: 6%, and no fill 66%, and the use of Ozempic for all eligible patients was 0.5 mg: 1%, 1 mg: 6%, 2 mg: 7%, and no fill: 86%
- Limitations when interpreting the results: propensity-score matching may not account for all potential confounders; this was a retrospective database analysis and not all confounding variables may have been collected in the database; administrative and pharmacy claims may not accurately reflect actual diagnoses and treatments; patients in the study were enrolled in commercial health insurance plans in the US and results may not be generalizable; requirement for continuous enrollment may result in selection bias; a small number of patients were excluded due to post-index events, which may bias results.
