Despite posting record Q2 growth for its blockbuster weight loss and diabetes drug tirzepatide, Eli Lilly is facing legal challenge from a lawsuit filed in Texas that accuses the pharma company of bribing providers to prescribe its drugs.
Attorney General for Texas Ken Paxton and Health Choice Alliance claim Eli Lilly “offered illegal incentives” to medical providers in the southern state so its most profitable drugs, including popular glucagon-like peptide-1 receptor agonist (GLP-1RA) medications tirzepatide, marketed as Mounjaro and Zepbound, would be preferentially prescribed to patients.
The marks the latest legal assault by the attorney general’s office, having previously sued Eli Lilly over an industry conspiracy to increase insulin prices. Health Choice Alliance has also filed previous legal action against Eli Lilly in the past.
In the latest filing, Paxton and Health Choice Alliance claim that Eli Lilly’s actions cost Texas Medicaid “millions of dollars”. The claimants argue that prescriptions were covered by the government insurance programme, resulting in claims to Texas Medicaid that were “tainted by Eli Lilly’s illegal marketing and quid pro quo arrangements”.
As per the filing, Lilly is alleged to have participated in two schemes to induce and influence providers. In the first, the pharma company, with the help of third parties, apparently provided free nursing services. The second scheme alleges that Lilly continues to offer reimbursement support services to get their drugs prescribed over rivals.
An Eli Lilly spokesperson told ɫ Technology that it intends to “vigorously defend against these allegations”.

By GlobalDataThe spokesperson added: “Multiple courts and the federal government have rejected claims by this same corporate relator against Lilly as meritless. In fact, the United States Government determined that ‘the relators’ allegations lack sufficient factual and legal support’ in a prior case, explaining that federal healthcare programs have a strong interest in ensuring that, after a physician has appropriately prescribed a medication, patients have access to basic product support relating to their medication.”
This referred to similar kickback claims previously made by Health Choice Alliance. Lilly was originally sued by the organisation in 2017, alleged to have participated in a “multi-tiered kickback scheme” along with other pharma companies, including Bayer. This involved offering free nursing services in exchange for preferential drug prescriptions.
The case was dismissed a year later by a judge in Texas. In 2021, a court of appeals upheld the prior decision to scrap the case amid attempts to revive the lawsuit.
It is also not the first time the state of Texas has accused Lilly of unlawful activities. In October 2024, the attorney general’s office sued several drugmakers and pharmacy benefit managers (PBMs) over insulin product prices. According to a statement at the time, Paxton accused manufacturers of a “conspiracy” to artificially and willingly raise insulin prices and then pay an undisclosed amount back to PBMs in a quid pro quo arrangement.
Lilly had a strong Q2 as it extended its lead over rival Novo Nordisk in the GLP-1RA treatment space. The company reported growth of 172% and 68% for Zepbound and Mounjaro, respectively. The two drugs brought in combined sales of $8.57bn in the quarter.
