Americaine Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Americaine (benzocaine) Anesthetic Lubricant is used to reduce pain or discomfort caused by minor skin irritations, sore throat, sunburn, teething pain, vaginal or rectal irritation, ingrown toenails, hemorrhoids, and many other sources of minor pain on a surface of the body. Benzocaine is also used to numb the skin or surfaces inside the mouth, nose, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum. It is a local anesthetic (numbing medication). The brand name Americaine is discontinued in the U.S. Generic versions may be available. Common side effects include mild stinging, burning, or itching where the medicine is applied, skin tenderness or redness, or dry white flakes where the medicine was applied.

Apply a dose of benzocaine evenly to exterior of tube or instrument prior to use. It is not likely that other drugs you take orally or inject will have an effect on topically applied benzocaine. But many drugs can interact with each other. Tell your doctor all prescription and over-the-counter medications and supplements you use. During pregnancy, benzocaine should be used only if prescribed. It is unknown if this drug passes into breast milk or if it could harm a nursing baby. Consult your doctor before breast-feeding.

Our Americaine (benzocaine) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
