President-elect Trump's threat to tariff Denmark if it resists his acquisition plans for the island territory of Greenland could disrupt one export that is wildly popular in America: Ozempic. ... Danish multinational pharmaceutical giant Novo Nordisk is the sole owner of semaglutide, the active ingredient in both Ozempic and Wegovy. A month's supply of Ozempic is close to $1,000 without insurance, though manufacturer coupons and patient assistance programs are available. Novo Nordisk was estimated to be responsible for half of Denmark's gross domestic product growth in 2024.
