Overview

• Eli Lilly has told UK wholesalers to stop taking new Mounjaro orders until 1 September to manage unprecedented demand triggered by a planned list‑price increase.
• The list price is set to rise by up to 170% from Monday, taking the 15mg dose from £122 to £330, but a confirmed commercial scheme would reduce the effective cost to £247.50 for that dose.
• Major chains including Boots, Lloyds Pharmacy and Superdrug reported intermittent stock or out‑of‑stock notices, with providers prioritising existing patients, capping supplies and pausing new starts.
• Lilly says allocations are in place and warns against inappropriate stockpiling, citing MHRA‑enforced protections to prevent bulk buying by providers.
• Pharmacists and regulators warn of black‑market risks as access tightens, with FOI data showing Border Force seized about 18,300 illegal weight‑loss and diabetes medications at Heathrow over 12 months.
