Compare Zepbound vs. Saxenda

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Tirzepatide (Zepbound) and liraglutide (Saxenda) are both medications used to help with weight loss in adults, and they belong to the class of glucagon-like peptide-1 (GLP-1) receptor agonists. However, they have some differences. Tirzepatide is also a glucose-dependent insulinotropic polypeptide (GIP) receptor agonist, while liraglutide is solely a GLP-1 agonist. Tirzepatide is approved for weight management and moderate-to-severe sleep apnea, whereas liraglutide is approved for weight management in adults and children over 12 years old. Tirzepatide is injected once a week, while liraglutide is injected daily. Both medications can cause side effects like nausea, diarrhea, and injection site reactions. Additionally, both tirzepatide and liraglutide have potential interactions with diabetes medications, warfarin (Jantoven, Coumadin), and birth control pills. Both medications are not recommended for people with a history of certain thyroid cancers.
