The use of complementary and alternative medicines by patients with peripheral neuropathy

Complementary and alternative medicine (CAM) therapies have become increasingly popular and are used regularly by patients with chronic neurological disorders. The prevalence and characteristics of CAM use by patients with peripheral neuropathy is unknown. We performed a prospective, questionnaire-based study to determine the prevalence and patterns of use of CAM therapies in 180 consecutive outpatients with peripheral neuropathy. The use of CAM was reported by 77 patients (43%) with neuropathy. The most frequent were megavitamins (35%), magnets (30%). acupuncture (30%), herbal remedies (22%), and chiropractic manipulation (21%); 37 (48%) tried more than one form of alternative treatment. Seventeen respondents (27%) thought their neuropathy symptoms improved with these approaches. Those who used CAM were slightly younger (mean age 62 vs. 65 years, p = 0.05) and more often college educated (39% vs. 24%, p = 0.03) compared to CAM nonusers. They also more often reported burning neuropathic pain (62% vs. 44%, p = 0.01). Patients with diabetic neuropathy used CAM more frequently than others (p = 0.03). The most common reason for using CAM was inadequate pain control (32%). Almost half of patients did not consult a physician before starting CAM. We conclude that there is a high prevalence of CAM use in our patients with neuropathy, and one-quarter reported that their symptoms improved. CAM users were better educated than nonusers, but most did not discuss CAM treatments with their physician. Neuropathic pain was substantially more common in CAM users, and lack of pain control was the most common reason for CAM use. (C) 2003 Elsevier B.V. All rights reserved.
