About 1.5 million people in the UK take Mounjaro or Wegovy, bought privately from online pharmacies

Overview

  • Eli Lilly told its two UK wholesalers to temporarily stop taking Mounjaro orders after demand spiked ahead of the list‑price rise.
  • The highest dose will increase from £122 to £330 next week, while a 5mg pen will rise from £92 to £180, as Lilly moves to align UK pricing with Europe.
  • Boots, Lloyds and Superdrug reported scarce or unavailable higher‑dose pens, with Superdrug saying it is out of stock and prioritising existing patients.
  • Online providers tightened access, with Simple Online Pharmacy pausing new‑patient sales and limiting supplies to four weeks, and Pharmacy2U prioritising current users.
  • Pharmacy leaders warned the disruption could push buyers toward illicit channels, citing Border Force seizures of about 18,300 fake or illegal weight‑loss and diabetes medicines at Heathrow over the past year.
