What is Orabase Gel-B (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.
There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.
Benzocaine topical may also be used for purposes not listed in this medication guide.
What is the most important information I should know about Orabase Gel-B (benzocaine topical)?
Benzocaine topical used in the mouth or throat may cause methemoglobinemia (met-HEEM-oh glo-bin-EE-mee-a), a life-threatening condition in which the amount of oxygen in your blood stream becomes dangerously low. Do not use benzocaine topical 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.
Do not use this medicine on a child younger than 2 years old without medical advice.
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. Use the smallest amount of this medication needed.
What should I discuss with my health care provider before using Orabase Gel-B (benzocaine topical)?
Do not use benzocaine topical if you have ever had methemoglobinemia in the past.
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). Be aware that many cosmetic procedures are performed without a medical doctor present.
Ask a doctor or pharmacist if it is safe for you to take this medicine if you have:
asthma, bronchitis, emphysema, or other breathing disorder;
a personal or family history of methemoglobinemia, or any genetic (inherited) enzyme deficiency; or
if you smoke.
FDA pregnancy category C. It is not known whether benzocaine topical will harm an unborn baby. Do not use this medicine without a doctor's advice if you are pregnant.
It is not known whether benzocaine topical passes into breast milk or if it could harm a nursing baby. Do not use this medicine without a doctor's advice if you are breast-feeding a baby.
Do not use this medicine on a child younger than 2 years old without medical advice.
How should I use Orabase Gel-B (benzocaine topical)?
Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Use the smallest amount of medicine needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice.
Your body may absorb more of this medication 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.
This medication comes with instructions for safe and effective application. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
To treat minor skin conditions, apply a thin layer of benzocaine topical to the affected area. If using the spray, hold the container 6 to 12 inches away from the skin. Do not spray this medication onto your face. Spray it instead on your hands and then rub it onto the face, avoiding contact with your eyes.
To treat hemorrhoids, clean the area with soap and water before applying benzocaine topical. Apply the medication up to 6 times per day. If you are using the rectal suppository, try to empty your bowel and bladder before inserting the suppository. Remove the outer wrapper from the suppository before inserting it. Avoid handling the suppository too long or it will melt in your hands.
Do not use benzocaine topical to treat large skin areas or deep puncture wounds. Avoid using the medicine on skin that is raw or blistered, such as a severe burn or abrasion.
Call your doctor if your symptoms do not improve or if they get worse within the first 7 days of using benzocaine topical. Also call your doctor if your symptoms had cleared up but then came back.
If you are treating a sore throat, call your doctor if the pain is severe or lasts longer than 2 days, especially if you also develop a fever, headache, skin rash, swelling, nausea, vomiting, cough, or breathing problems.
Store at room temperature away from moisture and heat. Do not freeze.
What happens if I miss a dose?
Since benzocaine topical is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of benzocaine topical applied to the skin can cause life-threatening side effects such as uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).
What should I avoid while taking Orabase Gel-B (benzocaine topical)?
Avoid eating within 1 hour after using benzocaine topical on your gums or inside your mouth.
Benzocaine topical is for use only on the surface of your body, or just inside the mouth, 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.
