Mounjaro 2.5 mg KwikPen Injection contains Tirzepatide, a novel once-weekly injectable medicine used for the management of Type 2 Diabetes Mellitus. Tirzepatide is a dual-acting incretin mimetic that targets both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptors.

The 2.5 mg dose is generally prescribed as a starting dose to allow gradual dose escalation and improved tolerability. Mounjaro helps improve blood sugar control by enhancing insulin secretion, reducing glucagon levels, slowing gastric emptying, and regulating appetite.
