Brand Name: Anestafoam
Lidocaine foam is used for:
Treating pain, itching, soreness, and discomfort of the skin or mucous membranes due to certain conditions such as minor cuts, minor burns, scrapes, insect bites, and sunburn.
Lidocaine foam is an anesthetic. It works by preventing nerves from transmitting painful impulses to the brain.

- you are allergic to any ingredient in lidocaine foam or to similar medications (eg, dibucaine)
Contact your doctor or health care provider right away if any of these apply to you.
Before using lidocaine foam:
Some medical conditions may interact with lidocaine foam. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have had a severe allergic reaction (eg, severe rash, hives, difficulty breathing, dizziness) to any anesthetic medicine
