In both male and female rats, Mounjaro has been linked to the development of thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). It is unknown whether or not Mounjaro causes these tumors in humans. However, Mounjaro is contraindicated in patients with a personal or family history of MTC. It is also contraindicated in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Patients with these conditions may receive counseling from their healthcare provider about the risks associated with Mounjaro use.
