Shares of Novo Nordisk experienced a significant uptick of over 3% this Wednesday following the FDA’s issuance of warning letters to 30 telehealth providers accused of making deceptive claims regarding compounded GLP-1 medications.
The regulatory notices targeted businesses that marketed compounded versions of semaglutide and tirzepatide using terminology such as “generic Zepbound” or “generic Mounjaro.” These are trademarked names for Eli Lilly’s tirzepatide-based treatments.
Additionally, certain providers marketed these compounds under proprietary brand names without clearly identifying themselves as the compounding entity. According to the FDA, this practice created the false impression that they were the original manufacturers.
The regulatory agency emphasized that compounded medications lack FDA approval and cannot be equated with generic pharmaceutical products.
“Compounded drugs can be important for overcoming shortages or meeting unique patient needs — but compounders should not try to compound drugs in a way that circumvents FDA’s approval process,” FDA Commissioner Marty Makary said in a statement.
Semaglutide serves as the active component in Novo Nordisk’s Wegovy and Ozempic products. Tirzepatide is the key ingredient in Eli Lilly’s Zepbound and Mounjaro. A handful of companies also faced citations for deceptive marketing of liraglutide, which Novo Nordisk markets as Saxenda.
FDA Escalates Enforcement Efforts
This marks the agency’s second major enforcement wave since initiating its regulatory crackdown last September. The initial round included warnings directed at companies such as Eli Lilly, Novo Nordisk, and digital health provider Hims & Hers Health.
The present enforcement action aligns with President Trump’s executive directive to strengthen oversight of direct-to-consumer pharmaceutical advertising. The FDA reports issuing thousands of similar notices in the past six months — exceeding the cumulative total from the previous ten years.
Recipients of these warning letters must provide written responses within 15 business days, detailing their plans to address the identified violations.
Hims & Hers has featured prominently in this regulatory campaign. In February, the FDA issued a warning regarding potential enforcement action concerning the company’s $49 compounded weight management medication. That same month, Novo Nordisk initiated legal proceedings against the company.
The FDA subsequently forwarded Hims & Hers’ case to the Department of Justice in early February.
Market Analyst Perspectives
Citi Research analysts indicated that these latest warning letters hold greater significance than typical enforcement actions due to the heightened regulatory climate.
The investment firm highlighted the DOJ referral as evidence that more severe penalties may await companies that fail to comply with regulations.
Citi analysts also observed that Commissioner Makary has separately indicated plans to impose restrictions on the active pharmaceutical ingredients available for use in compounded GLP-1 formulations. Such a policy would further constrain operations for compounding pharmacies.
The regulatory timing creates additional pressure as expanded Medicare coverage for GLP-1 medications approaches in the second quarter.
Novo Nordisk stock closed Wednesday’s trading session up 3.59%.
