Systemic analgesic medications such as nonsteroidal anti-inflammatory drugs play a significant role in controlling pain. However, use of these medications is often limited by patients’ tolerance.

Topical analgesics have minimal systemic effects and act directly at the site of pain. The advantage of a topical agent is a minimal risk of adverse side effects and drug interactions.

The Lidocaine patch use was initially approved by the US Food and Drug Administration (FDA) to control the pain of herpes zoster (shingles). More recently, the topical Lidocaine patch (known as the Lidoderm® patch) is more and more commonly used in conditions like chronic neck or lower back pain, osteoarthritis of joints, and myofascial (muscle type) pain.

The topical Lidocaine patch is a 10 x 14 centimeter patch that can be affixed directly to the affected areas – posterior neck, lower back, or knee. The Lidocaine patch can be used alone or in combination with systemic medications.

This medication has a distinct advantage, particularly in elderly patients who are more likely to be taking multiple medications. The regimen and number of Lidocaine patches to use is recommended and prescribed by physicians.
