Tirzepatide in South Africa

Tirzepatide is the active ingredient in Mounjaro — the newer dual-action (GIP/GLP-1) weight-loss and diabetes injection. Here's what it is, what it costs in SA, and how it stacks up against semaglutide.

What it is

Tirzepatide vs the semaglutide drugs

Tirzepatide is a once-weekly injection that mimics two gut hormones — GIP and GLP-1 — whereas semaglutide (the ingredient in Ozempic and Wegovy) targets GLP-1 alone. That dual action is why tirzepatide has produced the largest average weight loss of the current injections in clinical trials. In South Africa it is sold only as Mounjaro, distributed by Aspen.
