Mounjaro

What is Mounjaro?

Mounjaro contains the active ingredient tirzepatide, a GLP-1 and GIP receptor agonist. It behaves like the natural hormones GLP-1 and GIP to lower blood glucose concentrations, slow gastric emptying, regulate appetite and decrease food intake.

Mounjaro is a prescription medicine, and requires a prescription from a New Zealand registered healthcare professional.

The starting dose of Mounjaro is 2.5 mg once weekly. After 4 weeks, a prescribing healthcare professional may increase the dose to 5 mg once weekly, the first maintenance dose. Subsequent dose increases are to be determined by a prescribing healthcare professional.
