People paying privately for weight-loss drug Mounjaro in the UK face a rise in the cost of the treatment after manufacturer Eli Lilly said it was increasing the list price of the drug by as much as 170%.

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.

It comes as President Donald Trump pressures drugmakers to lower U.S. drug prices while hiking them abroad under a policy called "most favored nation."
