Under Trump pressure, Lilly hikes UK obesity jab price

15 August 2025

US pharma major Eli Lilly (NYSE: LLY) is raising the list price for its obesity drug Mounjaro (tirzepatide) in the UK by as much as 170%, as the pharma industry comes under pressure from US President Donald Trump to increase medicine prices in Europe and lower them for Americans.

The current list price in the UK for Lilly’s Mounjaro ranges from £92 ($124.89) to £122 ($165.55) a month, depending on the dose. This will increase to between £133 and £330 from September 1, with Lilly saying it aims to bring rates in line with other countries.
