Solarcaine Overview

Lidocaine is a prescription medication used to prevent pain before procedures or to relieve pain due to certain conditions. Lidocaine belongs to a group of drugs called local anesthetics. These stop nerves from sending pain signals to the brain.

This medication comes in several topical forms, including a patch to be applied to the skin (transdermal), ointment, cream, and oral solution. Lidocaine is an ingredient in some over-the-counter topical pain relievers. This page refers to the prescription forms of lidocaine.

This medication is also available in an injectable form to be given directly into a vein (IV) or for infiltration and nerve block by a healthcare professional.

Common side effects of topical lidocaine include irritation at site of application. Common side effects of injectable lidocaine include confusion, nervousness, and numbness. Lidocaine may also cause dizziness and drowsiness. Do not drive or operate heavy machinery until you know how this medication affects you.
