Tirzepatide

tirzepatide · GIP/GLP-1 receptor agonist

Once-weekly subcutaneous injection

Tirzepatide activates two gut-hormone receptors (GIP and GLP-1). It reduces appetite, slows how quickly the stomach empties, and helps regulate blood sugar, so you feel full on less food.

Boxed Warning

Thyroid C-cell tumors: In rodent studies, tirzepatide caused thyroid tumors, including cancer. It is unknown whether it causes these in humans. Do not use if you or a family member has ever had medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

  • Weight management in adults who are overweight (BMI ≥ 27) with a weight-related condition
