Shares of Novo Nordisk rallied over 3% during Wednesday’s trading session after federal health regulators sent warning letters to 30 telehealth providers accused of making deceptive marketing claims regarding compounded GLP-1 medications.

The warning letters focused on telehealth companies that promoted compounded versions of semaglutide and tirzepatide using terminology such as “generic Zepbound” or “generic Mounjaro.” These branded names belong to Eli Lilly’s tirzepatide-based treatments.

Certain providers also marketed these compounded medications under proprietary brand names without clearly identifying themselves as the compounding entity. According to the FDA, this practice created the false impression that these companies were authorized manufacturers.

The regulatory agency emphasized a crucial distinction: compounded medications lack FDA approval and cannot be characterized as generic equivalents.

Semaglutide serves as the primary component in Novo Nordisk’s weight-loss drug Wegovy and diabetes medication Ozempic. Tirzepatide powers Eli Lilly’s Zepbound and Mounjaro products. A handful of companies also faced citations for deceptive marketing of liraglutide, which Novo Nordisk markets under the Saxenda brand.

FDA Intensifies Enforcement Efforts

This enforcement action marks the second significant wave of regulatory warnings since the FDA initiated its compliance campaign in September. The initial round of letters addressed violations by companies including Eli Lilly, Novo Nordisk, and the telehealth platform Hims & Hers Health.

The recent regulatory push stems from President Trump’s executive directive targeting direct-to-consumer pharmaceutical advertising. According to the FDA, it has distributed thousands of enforcement letters over the last six months — surpassing the total volume from the previous ten years combined.

Firms receiving warning letters must submit written responses within 15 working days, detailing their plans to address and remedy the cited violations.

Hims & Hers has emerged as a frequent subject in this regulatory campaign. In February, the FDA issued warnings regarding potential enforcement action concerning the company’s $49 compounded weight-loss medication.

The FDA additionally forwarded Hims & Hers to the Department of Justice in early February.

Market Analyst Perspectives

Citi Research highlighted that the most recent warning letters hold heightened significance given the increasingly stringent regulatory climate.

The investment firm referenced the DOJ referral as evidence that more severe enforcement actions may be forthcoming for companies that fail to achieve compliance.

Citi Research also noted that Commissioner Makary has independently indicated plans to impose restrictions on the active pharmaceutical ingredients permitted in compounded GLP-1 formulations. Such regulatory changes would further constrain the operating environment for compounding pharmacies.

The enforcement timing creates additional pressure as the industry anticipates expanded Medicare coverage for GLP-1 medications, expected to commence during the second quarter.

Novo Nordisk shares gained 3.59% during Wednesday’s trading session.
