More on this analysis

Which obesity brand is named most often by UK community pharmacies in 2026?
GlaxoSmithKline's Alli leads UK community-pharmacy obesity brand mentions at 68.8%, based on Rare.Monitor's June 2026 audit of 2,518 GPHC-registered community pharmacies active in obesity treatments.
How does Mounjaro compare to Wegovy in UK community pharmacies?
Across 2,518 UK GPHC-registered community pharmacies audited in June 2026, Novo Nordisk's Wegovy and Eli Lilly's Mounjaro are effectively tied at 24.3% and 24.1% mention rate respectively (Rare.Monitor).
What is the difference between Alli and generic orlistat in UK community-pharmacy listings?
Alli is GlaxoSmithKline's over-the-counter orlistat 60mg brand. The generic Orlistat row in the Rare.Monitor analysis primarily reflects the prescription-only orlistat 120mg formulation dispensed by multiple generic manufacturers. The two share the same active molecule at different doses and dispensing tiers, so the rows are not competing products from different manufacturers.
Why does Ozempic appear on UK community-pharmacy obesity listings?
Ozempic is licensed in the UK for Type 2 diabetes. It appears at a 1.8% mention rate across the 2,518 UK GPHC-registered community pharmacies audited in June 2026 (Rare.Monitor). The data measures the presence of a brand name on a pharmacy listing; it does not record the indication for which Ozempic is dispensed at each location.
Which manufacturer has the broadest obesity brand footprint in UK community pharmacies?
Novo Nordisk has the widest brand footprint in the June 2026 Rare.Monitor audit of UK community pharmacies, with five obesity-licensed or obesity-adjacent products tracked (Wegovy, Semaglutide, Ozempic, Saxenda, Liraglutide). On single-brand mention rate, GlaxoSmithKline's Alli leads at 68.8%, ahead of generic orlistat at 44.4% and the GLP-1 injectables Wegovy (24.3%) and Mounjaro (24.1%).
