Overview

• Eli Lilly confirmed the UK list price of Mounjaro will rise from September, with the highest dose moving from about £122 to £330 a month.
• Supplier CheqUp reported a 27‑fold (2,660%) jump in UK Wegovy purchases after the announcement, with first‑dose sales up 2,212%.
• NHS commissioning is reported as unchanged, but private patients face far higher costs, with Wegovy priced at roughly £85–£160 per month.
• Clinicians and users warn higher prices and social‑media hype are feeding black‑market sourcing, with reports of counterfeit jabs causing serious harm and past global alerts over fakes.
• Eli Lilly said investigational drug retatrutide remains in trials and is not available outside them, as pharmacists caution the price shock could further fuel illicit demand.
