Does Zepbound (Tirzepatide) Cause Pancreatitis?

Yes, Zepbound (tirzepatide) can cause acute pancreatitis, and this is explicitly listed as a warning in the FDA drug label. 1

Risk of Pancreatitis with Zepbound

The FDA label for Zepbound clearly identifies acute pancreatitis as a potential risk and includes specific warnings about this adverse effect:

• Patients should be informed about the risk of pancreatitis
• Patients should discontinue Zepbound promptly if pancreatitis is suspected
• Symptoms requiring medical attention include severe abdominal pain that may radiate to the back, with or without vomiting 1

Evidence and Case Reports

Recent case reports have documented serious cases of pancreatitis associated with tirzepatide:

• A case of fatal, fulminant, necrotizing pancreatitis was reported in a 64-year-old female patient shortly after tirzepatide initiation 2
• Another case described acute pancreatitis in a 59-year-old male who had recently switched from semaglutide to tirzepatide 3

Risk Factors and Mechanisms

The risk of pancreatitis with GLP-1 receptor agonists like tirzepatide is well-established:

• GLP-1 receptor agonists as a class have been associated with increased risk of pancreatitis 4
• This association has been documented in multiple guidelines, including those from the American Diabetes Association 5
• The mechanism appears to be related to their effects on pancreatic function and gastric emptying

Monitoring and Management

For patients taking Zepbound:

1. Be vigilant for symptoms of pancreatitis:

   • Severe abdominal pain, especially radiating to the back
   • Nausea and vomiting
   • Elevated lipase levels

2. If pancreatitis is suspected:

   • Discontinue Zepbound immediately
   • Seek prompt medical attention
   • Perform appropriate diagnostic testing (lipase, amylase, imaging)

3. Risk assessment:

   • Consider existing risk factors for pancreatitis before prescribing
   • Patients with a history of pancreatitis require special consideration

Interesting Counterpoint

Despite the risk of acute pancreatitis with initial use, one recent study suggests that in patients with a history of acute pancreatitis, long-term use of tirzepatide might actually be associated with a lower recurrence rate (6.2%) compared to other GLP-1 receptor agonists like semaglutide (11.7%) 6. However, this finding should be interpreted cautiously given the clear warnings in the FDA label and documented case reports of severe pancreatitis.

Clinical Implications

The risk of pancreatitis should be carefully weighed against the benefits of Zepbound therapy. While the absolute risk appears to be relatively low, the potential severity of pancreatitis (including fatal cases) makes this a significant concern that requires appropriate patient education, monitoring, and prompt intervention if symptoms develop.
