The MHRA is willing to prosecute those who put patients' health at risk, said Alison Cave, the agency's chief safety officer. That hasn't happened yet in relation to Ozempic fakes. For Danish drugmaker Novo, the proliferation of counterfeits is a "critical issue" that the company says it's investigating with international and local health authorities. The company is also taking action on its own, working with a third party to monitor illegal online sales of drugs purporting to be Ozempic or Wegovy. In some cases, Novo works with a private-investigations firm to try to identify a manufacturer and report it to the authorities. While Morling and his team believe they have come down early and hard on fake products entering Britain, the weight-loss counterfeit market globally looks like it's only just getting started. In December, South Africa's drug regulator issued a warning about potentially fake Ozempic. That same month, the US said it had seized thousands of units.
