Overview

• Eli Lilly instructed UK wholesalers to stop taking Mounjaro orders until 1 September to manage unprecedented demand ahead of the new prices.
• The list price will rise by up to 170% next week, but a confidential scheme confirmed by Lilly offers pharmacy discounts that cut the top 15mg dose from an expected £330 to about £247.50, with the company citing European price alignment and US political pressure.
• Major chains including Boots, Lloyds and Superdrug report intermittent stock or out‑of‑stock notices, and providers are prioritising existing patients and restricting new starts or quantities.
• NHS procurement is reported as protected by separate arrangements, so the private price change is not expected to alter what NHS patients pay during the phased rollout.
• Suppliers report a surge in demand for rival Wegovy, and regulators and pharmacy bodies warn against black‑market products after Border Force seized thousands of fake weight‑loss injections at Heathrow.
