Dosage and Administration
Mounjaro, known generically as tirzepatide, is a prescription medication used to manage blood sugar levels in adults with type 2 diabetes. It belongs to a class of drugs known as dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonists. Mounjaro is administered as a subcutaneous injection using a single-dose, prefilled pen.
The typical starting dose of Mounjaro is 2.5 mg once per week. After 4 weeks, the dosage is usually increased to 5 mg per week. Depending on the individual’s response and blood sugar levels, the dosage may be further increased in 2.5 mg increments every 4 weeks. The maximum recommended dose is 15 mg once per week.
Patients are advised to inject Mounjaro once a week, on the same day each week, at any time of the day. The injection can be administered in the abdomen, thigh, or upper arm. It’s important to rotate the injection site with each dose to prevent skin irritation. If a dose is missed, it should be taken as soon as remembered within 4 days. If more than 4 days have passed, the missed dose should be skipped, and the next dose should be taken on the regularly scheduled day.
