Description
Mounjaro 40mg Pre-filled Pen (Tirzepatide) is used to help manage blood sugar levels in adults with type 2 diabetes and may also support weight loss when combined with diet and exercise. It is typically prescribed when other treatments have not provided adequate control.
Each pre-filled pen contains tirzepatide (40mg), a dual GIP and GLP-1 receptor agonist that works by improving insulin response, reducing appetite, and slowing gastric emptying.
Active ingredient: Tirzepatide 40mg
Form: Pre-filled injection pen
