Patient Education

Lidocaine Transdermal Patch


Prescription lidocaine transdermal (Dermalid, Lidoderm, Ztildo) is used to relieve the pain of post-herpetic neuralgia (PHN; burning, stabbing pains, or aches that may last for months or years after a shingles infection). Nonprescription (over-the-counter) lidocaine (Absorbine Jr, Aspercreme, Lidocare, Salonpas, others) is also available to relieve minor pain in shoulders, arms, neck and legs in adults and children 12 years of age and older. Lidocaine is in a class of medications called local anesthetics. It works by stopping nerves from sending pain signals.
