The Saudi Food and Drug Authority (SFDA) has warned against a product named Paiyoujui natural slimming capsules, which is used for dieting and sold on social media websites.

The product manufacturers claim that it is a natural product for losing weight, but it contains a harmful drug, said the regulatory agency.

In an advisory on its website, www.sfda.gov.sa, the SFDA said that lab analysis of the product revealed it contains Biburamine, a banned drug product.

The SFDA told consumers to avoid using the product and get rid of the samples they have.
