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

Key takeaways

Tirzepatide (Zepbound) and liraglutide (Victoza) are both injectable medications used to manage certain health conditions. They belong to the class of medications known as glucagon-like peptide-1 (GLP-1) agonists, which help control blood sugar levels and appetite. While both medications can aid in weight management, Zepbound is FDA-approved for weight loss and sleep apnea, whereas Victoza is approved for Type 2 diabetes and reducing heart-related risks in adults with diabetes. Zepbound is taken once a week, while Victoza is taken daily. Zepbound is a glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 receptor agonist, while Victoza is solely a GLP-1 receptor agonist. Common side effects for both medications include nausea and diarrhea. Both medications carry a risk of thyroid cancer and pancreatitis, and they have similar interactions, which can include other diabetes medications, warfarin (Jantoven, Coumadin), and birth control pills. Zepbound is available only as a brand-name medication, while Victoza has a lower-cost generic available.
