Tirzepatide is associated with a higher likelihood of gastrointestinal adverse events compared to other GLP-1 receptor agonists (semaglutide, dulaglutide, liraglutide, and exenatide).

If you take tirzepatide, expect gastrointestinal issues like nausea or vomiting more often than with other GLP-1 drugs. These are usually mild and go away, but they are the most common reason people stop the medication. Monitor your symptoms and report them.

The disproportionality analysis revealed that tirzepatide was associated with a higher likelihood of reported gastrointestinal AEs compared to GLP-1RAs. Specifically, tirzepatide exhibited a higher ROR (ROR: 1.35, 95 % CI: 1.47 - 1.23) and PRR (PRR: 1.16, 95 % CI: 1.26 - 1.06) than semaglutide...

Why this rating

Based on real-world pharmacovigilance data (EudraVigilance) using disproportionality analysis (ROR/PRR), which indicates signal strength but not causality.
