The US government has been pressing pharmaceutical companies to reduce domestic drug prices, which has led some firms to raise prices in markets abroad. Eli Lilly stated the Mounjaro price hike is intended to 'align' the UK price with other European markets.
Eli Lilly will raise the UK price of its weight-loss drug Mounjaro by 170% starting in September 2025, bringing new financial pressure for those paying privately. The monthly cost of the highest dose will jump from £122 (approximately $156) to £330 (approximately $422). The change comes amid broader pricing shifts driven by US government policy.
