FDA warns two joint-pain products contain hidden prescription drugs
Published
FDA lab tests found that RX7 Articulaciones and Ort-Flx, sold online including on eBay and possibly in some stores, contain the painkiller diclofenac and the steroid dexamethasone, and Ort-Flx also contains the muscle relaxant methocarbamol. None are on the labels. These can raise heart attack, stroke and bleeding risks and affect blood sugar. Don't buy them, and if you've been using one, call your doctor about stopping safely.
