What is Orajel?
Orajel contains benzocaine, a local anesthetic (numbing medication). It works by blocking nerve signals in your body.
Orajel numbs the skin or surfaces inside the mouth and used for the temporary relief of pain from sore throat, canker sores, cold sores, fever blisters, minor irritation or injury of the mouth and gums.
Orajel is also use for temporary relief of sore gums due to teething in children 2 years of age and older.
Orajel used in the mouth may cause a condition in which the oxygen in your body tissues can become dangerously low. This is a potentially fatal condition called methemoglobinemia (met-HEEM-oh glo-bin-EE-mee-a). Do not use this medicine if you have ever had methemoglobinemia.
GET EMERGENCY MEDICAL HELP IF YOU HAVE SYMPTOMS OF METHEMOGLOBINEMIA: headache, tired feeling, confusion, fast heart rate, and feeling light-headed or short of breath, with a pale, blue, or gray appearance of your skin, lips, or fingernails.
An overdose of benzocaine can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. Use the smallest amount needed.
Do not use Orajel on a child younger than 2 years old.
