Mounjaro is a prescription injectable medication used to treat type 2 diabetes in adults, helping improve blood sugar control alongside diet and exercise. The mounjaro brand name refers to tirzepatide, and the mounjaro class name is a dual GIP and GLP-1 receptor agonist, which works by supporting insulin release and reducing excess glucose production. Treatment typically begins at a lower dose and may be gradually increased based on your doctor’s guidance, with some patients eventually prescribed mounjaro 10 as part of their personalized plan. Patients are instructed to use the once-weekly Mounjaro® pen, injecting it under the skin of the abdomen, thigh, or upper arm on the same day each week for consistent results. Proper storage, rotating injection sites, and following your healthcare provider’s dosage schedule are essential for safe and effective therapy.
