The Danish drugmaker said it found impurities in all the drugs tested from Wells Pharmacy and Brooksville Pharmaceuticals, both based in Florida. Novo first sued Brooksville in July and discovered a substance called BPC-157 in samples from Wells.
Both cases were filed in Florida yesterday.
The pharmacies did not immediately respond to a request for comment by email today.
The US Food and Drug Administration banned BPC-157 from use in compounded drugs in September, saying it did not have enough data to know whether it was harmful to humans, but that it could cause dangerous immune system reactions.
Novo said the compounded versions of Wegovy tested from Brooksville were also less potent than advertised, with one sample shown to be at least 19% weaker than indicated.
“Compounded products do not have the same safety, quality, and effectiveness assurances as FDA-approved drugs, and adulterated and misbranded injectable compounded drugs may expose patients to significant health risks,” Jason Brett, a Novo Nordisk executive, said in a statement.
Novo said the lawsuits aim to stop the two pharmacies from selling products claiming to contain semaglutide – the main ingredient in Wegovy and Ozempic – and prevent Wells Pharmacy from claiming its products are FDA-approved or that BPC-157 has health benefits without making customers aware of its safety risks.
The drugmaker has already filed 12 lawsuits against medical spas, weight-loss clinics, and compounding pharmacies offering products that claim to contain semaglutide.
The company said it had obtained temporary orders against six of those to stop them from claiming their products are authentic, FDA-approved, or associated with Novo Nordisk.
Novo’s biggest rival in the obesity drug market, Eli Lilly, has also sued several medical spas, weight-loss clinics, and compounding pharmacies this year to stop them from selling products purporting to contain tirzepatide, the active ingredient in its diabetes drug Mounjaro and recently-approved weight loss medicine Zepbound.
The case against Wells was filed in the US district court, middle district of Florida, Ocala division, and the suit against Brooksville in US district court, middle district of Florida, Tampa division.
