The pricing of weight-loss and diabetes drugs like Lilly’s Zepbound and Mounjaro, and Novo’s Wegovy and Ozempic, is a pressure point for investors. Price erosion is a major worry amid increasing competition— including from knockoff versions of the drugs provided by telehealth pharmacies and coming patent expirations.

Eli Lilly will raise the UK list price of its weight-loss treatment Mounjaro by up to 170%, it said on Thursday, amid a White House push to get drugmakers to raise medicine prices in Europe to allow for price cuts in the United States.

Eli Lilly will significantly increase the price of its weight-loss drug Mounjaro in the United Kingdom in a bid to bring down prices in the United States after weeks of pressure from the Trump administration.
