FDA boxed warning
Mounjaro: Risk of thyroid C-cell tumors. Contraindicated in patients with personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).
Ozempic: Risk of thyroid C-cell tumors. Contraindicated in patients with personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2).
Mounjaro is tirzepatide (GIP/GLP-1 dual receptor agonist) and Ozempic is semaglutide (GLP-1 receptor agonist). They have different active ingredients and slightly different side-effect profiles.
Head-to-head trial data favors tirzepatide-based medications (Mounjaro, Zepbound) over semaglutide-based medications (Ozempic, Wegovy) in average percent weight loss. SURMOUNT-1 reported ~20.9% mean weight loss on tirzepatide 15 mg; STEP 1 reported ~14.9% on semaglutide 2.4 mg over comparable timelines.
