WOW is a supplement that has been sold over the internet for those seeking pain relief. The FDA has determined that it contains at least one ingredient which is considered a prescription-use only ingredient. In addition, one ingredient, Reumofan Plus, has been associated with heart attacks, stroke, bleeding, and gastrointestinal ulcers. Another ingredient, methocarbamol, may cause fatigue, dizziness, and low blood pressure. A third ingredient has been identified in some batches, dexamethasone, which is a corticosteroid. Bottom Line: discontinue the use of Wow if you’ve been using it–call your health care provider for options which may be safer for you.
