The European Medicines Agency (EMA) has issued a serious warning about a sharp rise in illegal weight loss drugs being sold as approved medications. These fake products are being promoted on websites and social media platforms like Facebook, misleading people into thinking they are buying safe and effective treatments. The EMA stresses that these unregulated drugs pose a major threat to public health. The illegal products are copying real medications like semaglutide (sold as Wegovy and Ozempic) and tirzepatide (sold as Mounjaro), which are used for weight loss and diabetes treatment. These drugs are highly popular and generate billions in sales each year. Fake sellers are using official logos and fake endorsements to trick buyers. The counterfeit drugs may not even contain the right ingredients and could instead have harmful substances. The EMA is working with authorities to shut down these illegal sellers, but the risk remains high for anyone buying these unapproved products. People who use them could face serious health problems, including dangerous reactions with other medications. This issue is growing worldwide, with fake versions of these drugs being found in multiple countries. In Ireland, authorities seized over 1,400 illegal units in 2024, compared to just 568 in 2023. The World Health Organization (WHO) has also reported fake semaglutide in Brazil, the UK, and the US. Many people turn to illegal sellers due to drug shortages and lower prices, but this puts them at risk of scams or unsafe products. Experts warn that nearly half of online pharmacies selling these drugs in the US may be illegal or unsafe. While some online pharmacies are legitimate, others are fraudulent, making it difficult for patients to tell the difference. The EMA and other health authorities are working to stop these illegal sellers, but consumers must stay alert to avoid dangerous fake medications.
