The common over-the-counter cough medication dextromethorphan may help people with fibromyalgia, according to a small study by University of Florida researchers.The study of 14 women with fibromyalgia and 10 women without the disease found dextromethorphan appears to temporarily reduce the intensity of “wind-up,” a cascading pain response to minor, repetitive physical touch, which is symptom of the syndrome.The study appears in the May issue of the Journal of Pain.
