What does the Mounjaro label say to do?
The pancreatitis section of the Mounjaro label says that if pancreatitis is suspected, discontinue Mounjaro and initiate appropriate management [1]. The label notes that acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed with GLP-1 receptor agonists or Mounjaro [1]. It lists persistent or severe abdominal pain, sometimes radiating to the back, as a possible sign; nausea or vomiting may or may not accompany it [1].
What do trials show about pancreatitis risk?
A 2023 meta-analysis pooled nine randomized tirzepatide trials in type 2 diabetes and obesity, 9,871 participants (6,828 on tirzepatide, 3,043 controls), and found no statistically significant increase in pancreatitis (RR 1.46, 95% CI 0.59 to 3.61) [2]. The same analysis found a significant increase in the composite of gallbladder or biliary disease (RR 1.97, 95% CI 1.14 to 3.42) [2]. A 2025 meta-analysis of 21 randomized trials involving 99,599 patients compared GLP-1 receptor agonists, including tirzepatide, with placebo or other controls and found no difference in pancreatitis between groups [3].
Related findings in the label
In the pooled placebo-controlled adult trials, abdominal pain was reported by 4% of placebo patients and 5% to 6% of tirzepatide patients, nausea by 4% and 12% to 18%, and vomiting by 2% and 5% to 9% [1]. The label reports mean increases from baseline in serum pancreatic amylase of 33% to 38% and in lipase of 31% to 42%, and states that the clinical significance of elevations in lipase or amylase is unknown in the absence of other signs and symptoms of pancreatitis [1]. Acute gallbladder disease was reported in 0.6% of Mounjaro-treated patients and 0% of placebo-treated patients; the label says that if cholelithiasis is suspected, gallbladder studies and clinical follow-up are indicated [1].
Can Mounjaro be restarted after an episode?
The pancreatitis section of the label instructs discontinuation if pancreatitis is suspected and does not describe restarting the drug after an episode [1].
