Lidocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.
Lidocaine topical (for use on the skin) is used to reduce pain or discomfort caused by skin irritations such as sunburn, insect bites, poison ivy, poison oak, poison sumac, and minor cuts, scratches, or burns. Lidocaine topical is also used to treat rectal discomfort caused by hemorrhoids.
Lidocaine topical may also be used for purposes not listed in this medication guide.

Use this medicine exactly as directed on the label, or as it has been prescribed by your doctor. Do not apply this medicine in larger amounts than recommended. Improper use of lidocaine topical may result in death. Lidocaine topical comes in many different forms (gel, spray, cream, lotion, ointment, liquid, skin patch). Do not take by mouth. Lidocaine topical is for use only on the skin. If this medicine gets in your eyes, nose, mouth, rectum, or vagina, rinse with water. Use the smallest amount of medicine needed to numb the skin or relieve pain. Your body may absorb too much of this medicine if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin. Do not apply this medicine to swollen skin areas or deep puncture wounds. Avoid using the medicine on skin that is raw or blistered, such as a severe burn or abrasion. Do not cover treated skin unless your doctor has told you to. Lidocaine topical may be applied with your finger tips or a cotton swab. If your medicine comes with patient instructions for safe and effective use, follow these directions carefully. Ask your doctor or pharmacist if you have any questions. Store at room temperature away from moisture and heat.
