Federal laboratory testing has found a prescription corticosteroid in a product sold online for pain relief, and the drug does not appear anywhere on the label. The Food and Drug Administration is advising consumers not to buy or use Qu Feng Huo Lou Dan, which the agency says has been promoted and sold on various websites, including newgreenusa.com, and possibly in some retail stores.
The hidden ingredient is dexamethasone, a steroid that requires a prescription in the United States and that carries meaningful risks when taken without medical supervision. Anyone who has been using this product should call a clinician before doing anything else, including before stopping it.
