Lidocaine: What It Does and How to Use It Safely

Lidocaine is a common local anesthetic you’ve probably used or heard about. It numbs a small area of the body so doctors can do minor procedures, dentists can work without pain, and people can ease sore spots with creams or patches. This page explains the main forms, quick safety tips, and when to ask for help.

Common forms and how they're used

There are a few ways lidocaine comes: injectable (for procedures), topical cream or gel (for skin pain, minor burns, insect bites), patches (for nerve pain like postherpetic neuralgia), and sprays (for throat or mucous membranes). Over-the-counter items usually have low concentrations for short-term use. Prescription versions are stronger and used for procedures or ongoing nerve pain.

Topical lidocaine works fast—often within minutes—and gives temporary numbness. Patches stick to the area and release medicine slowly over hours. Injectable lidocaine is given by a clinician to block nerves during minor surgery or dental work. Don’t try injections at home unless instructed by a healthcare professional.

Safety, side effects, and interactions

When used correctly, lidocaine is safe for most people. Mild side effects include redness, swelling, or a temporary burning feeling where it’s applied. More serious reactions—dizziness, ringing in the ears, confusion, fast heartbeat, or difficulty breathing—are signs of overdose or an allergic reaction. If those happen, get emergency help.

Avoid using large amounts over broad areas, especially under bandages, unless directed by a doctor. Children and older adults are more sensitive. Don’t apply topical lidocaine to broken skin unless the product says it’s okay. If you use medicines for heart rhythm (like amiodarone) or other local anesthetics, tell your doctor—there can be interactions.

If you’re pregnant or breastfeeding, ask your provider before using lidocaine. Small topical doses are often allowed, but injectable use during delivery or surgery needs a clinician’s judgment. Also mention any liver problems—your body processes lidocaine in the liver, so dosing might need adjustment.

Short practical tips: read the label, follow dose limits, avoid mixing multiple lidocaine products, and keep patches away from pets and kids. If pain or skin problems get worse after use, stop and contact a health professional.
