We have found that a 5% lidocaine patch (Lidoderm; Endo Pharmaceuticals Inc, Chadds Ford, Pa) is helpful as both first-line and adjunctive treatment for managing the pain of erythromelalgia. (Lidoderm is manufactured by Teikoku Seiyaku Co Ltd, Sanbonmatsu, Kagawa, Japan, for Endo Pharmaceuticals and is a registered trademark of Hind Health Care, Inc, San Jose, Calif.) This form of topical lidocaine has been approved by the US Food and Drug Administration for the relief of pain associated with postherpetic neuralgia.1 We previously reported our experience with this patch in treating a young woman who was disabled because of her erythromelalgia.2 Her pain has been controlled with the topical lidocaine patch for 3 years, and she continues to use the lidocaine patch as the sole intervention for erythromelalgia.
