Description

Mounjaro® (tirzepatide) is a prescription-only injectable medicine developed by Eli Lilly, licensed in the UK for weight management in adults with obesity (BMI ≥30), or overweight (BMI ≥27) with weight-related health problems such as type 2 diabetes, hypertension, or sleep apnoea.

Mounjaro works differently from other treatments by mimicking two naturally occurring hormones – GIP and GLP-1 – that help regulate blood sugar levels, appetite, and food intake. This dual-action mechanism helps to reduce hunger, control cravings, and improve the body’s ability to use insulin effectively.

When used alongside lifestyle changes, Mounjaro has been shown in clinical studies to help people lose up to 20% of their body weight – making it one of the most effective prescription weight loss treatments available.

At The Health Dispensary, our qualified pharmacist prescribers provide personalised consultations and ongoing support to help you use Mounjaro safely and achieve the best possible results.
