Novo Nordisk is slashing the price of its blockbuster diabetes drug Ozempic for U.S. patients who self-pay or are uninsured.

Novo Nordisk and GoodRx announced a partnership this week to sell products Ozempic and Wegovy at half their normal cost to patients who pay for the medications with cash. Starting this week, customers will be able to buy a month’s supply of Novo Nordisk’s semaglutide pen products for $499 through GoodRx.

Novo Nordisk said on Monday it was offering its diabetes drug Ozempic for $499 per month to eligible cash-paying patients with type 2 diabetes in the U.S. via its own pharmacy, a tie-up with telehealth service GoodRx and other platforms.
