What is benzocaine topical?

Benzocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.

Benzocaine topical 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.

Benzocaine topical may also be used for other purposes not listed in this medication guide.

Precautions

An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

Do not use benzocaine topical if you have a blood cell disorder called methemoglobinemia.

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before using benzocaine topical, tell your doctor if you have:

  • asthma, bronchitis, emphysema, or other breathing disorder;
  • heart disease;
  • a personal or family history of methemoglobinemia, or any genetic enzyme deficiency; or
  • if you smoke.

FDA pregnancy category C. It is not known whether this medication is harmful to an unborn baby. Before using benzocaine topical, tell your doctor if you are pregnant or plan to become pregnant during treatment.

It is not known whether benzocaine topical passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Do not use this medicine on a child younger than 1 year old.

Benzocaine topical is for use only on the surface of your body, or just inside the vagina or rectum. Avoid getting this medication in your eyes. Avoid swallowing the gel, liquid, or ointment while applying it to your gums or the inside of your mouth. The throat spray or oral lozenge may be swallowed gradually during use.

Avoid eating within 1 hour after using benzocaine topical on your gums or inside your mouth.
