Novo Nordisk had been providing Hims & Hers with the FDA-approved Wegovy, an injectable semaglutide used for weight loss since late April in order to transition patients off compounded drugs, or off-label versions of the medication, according to the news release.

Novo Nordisk said Hims & Hers has "failed to adhere to the law which prohibits mass sales of compounded drugs" under the "false guise" of personalization.

Novo Nordisk said Monday it will end its collaboration with Hims & Hers that offered the weight loss medication Wegovy for patients who have a prescription for the medication but no insurance coverage for it.
