Tirzepatide: what it is and who it is for.

Tirzepatide is a prescription-only medicine used in weight management, alongside diet and physical activity. This page explains how it works, who it may be suitable for, who it is not suitable for, and what our online assessment involves.

How tirzepatide works

Tirzepatide (Mounjaro®) acts on two hormone receptors, GIP and GLP-1, rather than one. It is a prescription-only medicine and is not suitable for everyone.

  • Dual-Action MechanismActivates both GIP and GLP-1 receptors, which are involved in appetite and blood sugar control.
  • Alongside Diet and ActivityPrescribed as part of a plan that includes a reduced-calorie diet and more physical activity, not instead of them.
  • Licensed in the UKLicensed for weight management in adults with a qualifying BMI. Your prescriber decides whether it is suitable for you.
