What is Mounjaro?
Mounjaro is the brand name for tirzepatide, sometimes called a "twincretin" because it activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors — unlike Ozempic, Wegovy and Saxenda, which act on GLP-1 alone. This dual mechanism is one reason it's often discussed alongside, rather than simply grouped with, other GLP-1 medications.
In South Africa, Mounjaro is registered for managing type 2 diabetes. Internationally, tirzepatide is also marketed under a separate brand for weight management; that distinct weight-management registration is not the focus of this page.
Different mechanism, similar comparison basis
Because tirzepatide works differently to semaglutide and liraglutide, your doctor may recommend it over other options for specific health reasons — this is a clinical decision, not a pricing one.
