Tirzepatide

Dual GIP/GLP-1 agonist

Prescription medicine

What it is

A dual GIP/GLP-1 receptor agonist used in metabolic and weight management contexts.

What the evidence shows

Supported by large randomised trials in diabetes and weight management. As with semaglutide, that evidence is for the registered, brand-name product.

Safety & reported risks

Gastrointestinal side effects are common and prescribers screen for contraindications. Unapproved or compounded copies fall outside that oversight.

Status in Australia

A registered prescription medicine in Australia for defined indications. Supply is via prescription and dispensing pharmacy.

How it’s lawfully accessed

Lawful access is via prescription and pharmacy dispensing of the registered product, subject to availability.
