The launch of the weight-loss drug Wegovy has sparked fresh concerns among pharmacists in the UK, who warn that the new tablet format could make it easier for manufacturers to produce and sell counterfeit medicines. Wegovy Demand Sparks Counterfeit Concern The once-daily semaglutide pill, developed by Novo Nordisk, recently became available through private high street and online pharmacies after receiving approval from the UK's Medicines and Healthcare products Regulatory Agency (MHRA). While the pill is expected to help patients who are reluctant to use injections, experts fear it may also increase the risk of a growing black market for fake weight-loss drugs. According to a survey conducted by the National Pharmacy Association (NPA) with 310 pharmacies, 97% believe that the weight loss tablet could lead to an increase in counterfeit products being sold unlawfully. Olivier Picard, chairman of the National Pharmacy Association said, “As this survey shows, pharmacies are concerned about a dangerous and growing black market for weight loss medicines, with tablet form of medication likely to be easier for criminals to counterfeit.” He said that all patients must visit an authorised pharmacy for Wegovy pills. He added: “Patients should only ever obtain weight loss medication from a regulated pharmacy after an appropriate consultation with a healthcare professional. Fake medicines pose a serious risk to health because they may contain harmful ingredients or incorrect doses.” Also read: Wegovy Weight Loss Pill Available in UK Pharmacies From Today: All You Should Know Global Concern Unlike injectable medications of GLP-1, tablets often require less sophisticated manufacturing equipment, which makes it easier to make counterfeits. As the medicated weight loss market is rising after the popularity of GLP-1 medications increased, criminals can produce fake pills on a large scale, using simple equipment. Counterfeit GLP-1 medicines have already become a growing global concern. In September 2025, the European Medicines Agency (EMA) said that there had been a sharp rise in illegal forms of semaglutide and other GLP-1 medicines online. The agency also warned that these fake medicines may contain no active ingredient, improper doses, or harmful substances that can lead to failure of treatment or serious health complications. Demand for GLP-1 medicines such as Wegovy and Mounjaro has soared worldwide as studies continue to demonstrate significant weight loss benefits.

Clinical trials of the oral Wegovy tablet have shown participants taking the highest dose lost approximately 14% to 17% of their body weight over 64 weeks when combined with diet and exercise. However, pharmacists say the popularity of these treatments has also created opportunities for fraudsters. Experts urge consumers to avoid purchasing weight-loss medicines from unofficial online sellers or social media advertisements, regardless of how attractive the prices appear. Genuine GLP-1 medicines require a medical consultation and prescription, and authorised pharmacies carry out necessary clinical checks before selling them.
