According to FDA, Reumofan Plus and Reumofan Plus Premium that are marketed as natural remedies for arthritis and muscle pain contain several prescription drugs.
A chemical analysis revealed that Reumofan Plus contains three drugs, including the muscle relaxant methocarbomal and the anti-inflammatory drug dexamethasone, that can interact with other medications, causing life-threatening side effects in some patients.
The FDA initailly warned consumers about the products in June 2012, but says complications have continued to be reported.
