Dextromethorphan in Fibromyalgia

Summary

The objective of this protocol is to evaluate if Dextromethorphan (DXM) reduces Fibromyalgia (FM) pain. DXM is a drug found in several over-the-counter products, including cough suppressants. The drug may reduce FM pain by suppressing inflammation in the central nervous system. The investigators will be observing the effects of DXM on daily self-reported pain measures in people with FM. If DXM reduces FM pain, it will provide important information about the nature of FM pathophysiology.
