Lilly’s Mounjaro more popular than Wegovy in UK’s private obesity drug market

Britons paying privately for obesity drugs are increasingly choosing Eli Lilly’s Mounjaro over Novo Nordisk’s Wegovy, online pharmacies say, in a sign the US drugmaker is gaining ground on its European rival. Mounjaro is appealing to people because of its greater efficacy, six online pharmacies and two patients told Reuters, showing Novo’s first-mover advantage is being challenged in the UK even though some pharmacies sell starter doses for the weekly injection for up to 40 per cent more than Wegovy. “Mounjaro is now vastly outstripping Wegovy,” said Chemist4U CEO James O’Loan, who said for the past three to four months, Mounjaro has won about 70 per cent of its sales. Chemist4U and another online seller, Simple Online Pharmacy, estimate that as many as 500,000 people in the UK currently take either Mounjaro or Wegovy via prescriptions from private online pharmacies. Mounjaro, unlike Wegovy, is not available through the National Health Service (NHS) though it likely will be next year. Wegovy is only available through the NHS at specialist obesity clinics and in limited circumstances. There is no public data on prescription numbers but the government said last year it had capacity to treat about 35,000 patients.
