Medication details



Mounjaro® is a revolutionary medicine for adults with type 2 diabetes and those seeking weight management solutions. Containing the active substance Tirzepatide, Mounjaro works by reducing blood sugar levels when they are high and aiding in weight loss and maintenance by regulating appetite. It is suitable for use alone when metformin cannot be taken or in combination with other diabetes medications when additional blood sugar level control is necessary. Additionally, Mounjaro supports weight loss and maintenance in conjunction with a reduced-calorie diet and increased physical activity for adults with obesity or overweight with weight-related health issues. Available in pre-filled pens for convenient injection, it offers a new hope for effective diabetes management and weight control.

Each pen comes with 4 doses (with needles) to be taken once a week.

To use Mounjaro effectively, start with the prescribed dose, injecting once a week on the same day. Administer injections in the abdomen, thigh, or upper arm, rotating sites to avoid irritation. Before injecting, clean your hands and the injection area. Let refrigerated medication warm slightly for comfort. Use clean techniques for needle attachment and injection, disposing of sharps properly. Store the medication in the fridge or briefly at room temperature as allowed. If a dose is missed, take it soon if within a few days; otherwise, skip it and never double dose. Regularly consult with your healthcare provider to adjust doses and discuss any side effects. Always follow your healthcare provider's detailed instructions.


Tirzepatide, the active substance in Mounjaro, works by mimicking the actions of natural hormones in the body that regulate blood sugar and appetite. As a dual GIP (Glucose-dependent Insulinotropic Polypeptide) and GLP-1 (Glucagon-like Peptide-1) receptor agonist, it enhances insulin secretion in response to high blood sugar levels, slows down gastric emptying, and reduces appetite and food intake, leading to improved glycemic control and weight loss in adults with type 2 diabetes mellitus.

Side Effects

Gastrointestinal issues (nausea, vomiting, diarrhea, constipation), potential hypoglycemia (especially when used with other diabetes medications), injection site reactions, and possibly others depending on the individual's health condition and other medications being taken.


When using Mounjaro (tirzepatide), important precautions include being vigilant for severe abdominal pain indicative of pancreatitis, monitoring blood sugar levels due to the risk of hypoglycemia when combined with other diabetes medications, reporting any changes in urination that could signal kidney issues, and seeking immediate medical attention for persistent digestive problems like vomiting or diarrhea. It's also crucial to inform your doctor of any personal or family history of thyroid cancer, given studies in rodents linking Mounjaro-like medications to thyroid issues. Be alert for signs of allergic reactions, and if you're pregnant or breastfeeding, consult with your healthcare provider about potential risks.
