FDA Warning Letters about Fibromyalgia Products

A warning letter is a serious notice to that a marketer appears to be violating federal law and may be subject to enforcement action if the apparent violation continues. Enforcement actions include seizure of goods, injunctions, criminal prosecutions, fines, and imprisonment. Most sellers do what the FDA requests.
