Durability of Benefit From Repeated Intravenous Lidocaine Infusions in Fibromyalgia Patients: A Case Series and Literature Review

Fibromyalgia is a painful disorder with no curative treatments, and available medications typically provide partial relief of pain. Reported here is the effective use of serial intravenous lidocaine infusions for the chronic management of 3 patients with fibromyalgia. The details of the infusion procedure are described, and relevant literature is reviewed. Lidocaine infusions should be considered in fibromyalgia patients who are refractory to other treatments, and a positive response to 1 infusion may justify repeated infusions for chronic management.
