Every UK Mounjaro price. Every dose. Every source.

Among the pharmacies with verified prices on 14 November 2026, the lowest listed 2.5mg pen is £108.90 and prices rise with the dose. A pen holds four weekly doses, so the monthly cost equals the pen price plus delivery.

Only from pharmacies themselves. Pharmacies add and update their own codes through a verified listing, and we check them before they appear.
