Oral Over-the-Counter Benzocaine Products: Drug Safety Communication - Risk of Serious and Potentially Fatal Blood Disorder
May 23, 2018
Audience: Pediatrics, Dentistry, Consumer, Health Professional, Pharmacy
ISSUE: The FDA is warning that over-the-counter (OTC) oral drug products containing benzocaine should not be used to treat infants and children younger than 2 years. We are also warning that benzocaine oral drug products should only be used in adults and children 2 years and older if they contain certain warnings on the drug label. These products carry serious risks and provide little to no benefits for treating oral pain, including sore gums in infants due to teething. Benzocaine, a local anesthetic, can cause a condition in which the amount of oxygen carried through the blood is greatly reduced. This condition, called methemoglobinemia, can be life-threatening and result in death. Due to the significant safety risk of methemoglobinemia, we have urged manufacturers that they should stop marketing OTC oral drug products for treating teething in infants and children younger than 2 years. If companies do not comply, we will take action to remove these products from the market.
We have also urged manufacturers of OTC oral drug products containing benzocaine for adults and children 2 years and older to make the following changes to the labels of their products:
Adding a warning about methemoglobinemia;
Adding contraindications, FDA’s strongest warnings, directing parents and caregivers not to use the product for teething and not to use in infants and children younger than 2 years; and
Revising the directions to direct parents and caregivers not to use the product in infants and children younger than 2 years.
BACKGROUND: Benzocaine is a local anesthetic contained in some OTC products for the temporary relief of pain due to minor irritation, soreness, or injury of the mouth and throat. Benzocaine products are marketed as gels, sprays, ointments, solutions, and lozenges under brand names such as Anbesol, Orabase, Orajel, Baby Orajel, Hurricaine, and Topex, as well as store brands and generics. Prescription local anesthetics include articaine, bupivacaine, chloroprocaine, lidocaine, mepivacaine, prilocaine, ropivacaine, and tetracaine.
RECOMMENDATION: We continue to monitor the safety and effectiveness of OTC benzocaine products and intend to take additional actions in the future as needed. We will notify the public about any updates. In addition to our recent actions regarding OTC benzocaine products, we are also requiring a standardized methemoglobinemia warning to be included in the prescribing information of all prescription local anesthetics.
Parents and caregivers should follow the American Academy of Pediatrics’ recommendations for treating teething.
Gently rub or massage the child’s gums with one of your fingers.
Use a firm rubber teething ring.
Topical pain relievers and medications that are rubbed on the gums are not useful because they wash out of a baby’s mouth within minutes. FDA has previously cautioned parents and caregivers to not give certain homeopathic teething tablets to children. Alternative treatments for adults who experience mouth pain may include dilute salt water mouth rinse and OTC pain relief medications. Adults should follow the American Dental Association’s recommendations for mouth sores:
Schedule regular oral health checkups
Keep a diary of what you eat and drink
Keep a list of oral hygiene products you have been using
Avoid all tobacco products
If you drink alcoholic beverages, do so in moderation
See your dentist if you notice any change in your mouth.
Consumers using benzocaine products to treat mouth pain should seek medical attention immediately for signs and symptoms of methemoglobinemia. These include pale, gray or blue-colored skin, lips, and nail beds; shortness of breath; fatigue; confusion; headache; lightheadedness; and fast heart rate. Signs and symptoms of methemoglobinemia may appear within minutes to one to two hours after using benzocaine. Symptoms may occur after using benzocaine for the first time, as well as after prior uses.
Health care professionals should warn patients of the possibility of methemoglobinemia and advise them of the signs and symptoms when recommending or prescribing local anesthetic products. Some patients are at greater risk for complications related to methemoglobinemia. This includes those with breathing problems such as asthma, bronchitis, or emphysema; heart disease, and the elderly. Health care professionals using local anesthetics during medical procedures should take steps to minimize the risk for methemoglobinemia. These include monitoring patients for signs and symptoms suggestive of methemoglobinemia; using co-oximetry when possible; and having resuscitation equipment and medications readily available, including methylene blue.
Healthcare professionals and patients are encouraged to report adverse events or side effects related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program.
Benzocaine Topical Products: Sprays, Gels and Liquids - Risk of Methemoglobinemia
Apr 7, 2011
Audience: Family Practice, Pharmacy, Consumers
ISSUE: FDA notified healthcare professionals and patients that FDA continues to receive reports of methemoglobinemia, a serious and potentially fatal adverse effect, associated with benzocaine products both as a spray, used during medical procedures to numb the mucous membranes of the mouth and throat, and benzocaine gels and liquids sold over-the-counter and used to relieve pain from a variety of conditions, such as teething, canker sores, and irritation of the mouth and gums.
BACKGROUND: Methemoglobinemia is a rare, but serious condition in which the amount of oxygen carried through the blood stream is greatly reduced. In the most severe cases, methemoglobinemia can result in death. Patients who develop methemoglobinemia may experience signs and symptoms such as pale, gray or blue colored skin, lips, and nail beds; headache; lightheadedness; shortness of breath; fatigue; and rapid heart rate. Methemoglobinemia has been reported with all strengths of benzocaine gels and liquids, and cases occurred mainly in children aged two years or younger who were treated with benzocaine gel for teething. The signs and symptoms usually appear within minutes to hours of applying benzocaine and may occur with the first application of benzocaine or after additional use. The development of methemoglobinemia after treatment with benzocaine sprays may not be related to the amount applied. In many cases, methemoglobinemia was reported following the administration of a single benzocaine spray.
- Benzocaine products should not be used on children less than two years of age, except under the advice and supervision of a healthcare professional.
- Adult consumers who use benzocaine gels or liquids to relieve pain in the mouth should follow the recommendations in the product label. Consumers should store benzocaine products out of reach of children. FDA encourages consumers to talk to their healthcare professional about using benzocaine.
- Read the two Drug Safety Communications below for other specific recommendations for Healthcare Professionals, for Consumers and Caregivers and the Data Summary which supports these recommendations.
FDA is continuing to evaluate the safety of benzocaine products and the Agency will update the public when it has additional information. FDA will take appropriate regulatory actions as warranted.
Healthcare professionals and patients are encouraged to report adverse events, side effects, or product quality problems related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program:
Jan 16, 2009
Audience: Consumers, radiological healthcare professionals, emergency room healthcare professionals, risk managers[Posted 01/16/2009] FDA issued a public health advisory to remind patients, healthcare professionals, and caregivers about potentially serious hazards of using skin numbing products, also known as topical anesthetics, for relieving pain from mammography and other medical tests and conditions. FDA is concerned about the potential for these products to cause serious, life-threatening adverse effects, such as irregular heartbeat, seizures, breathing difficulties, coma and even death, when applied to a large area of skin or when the area of application is covered. FDA is working with healthcare professional organizations and other media that distribute healthcare information to spread the message about the potential hazards and safe use of topical anesthetics. The Advisory and the Dear Colleague letter provide recommendations to both doctors and patients on safe use of these products.

Feb 13, 2006
Audience: Healthcare professionals and patients[Posted 02/13/2006] FDA issued a Public Health Advisory to notify healthcare professionals and patients about adverse events, including methemoglobinemia, associated with the use of benzocaine sprays used in the mouth and throat. Benzocaine sprays are used in medical practice for locally numbing mucous membranes of the mouth and throat for minor surgical procedures or when a tube must be inserted into the stomach or airways. On February 8, 2006, the Veterans Health Administration (VA) announced the decision to stop using benzocaine sprays for these purposes. The FDA is aware of the reported adverse events and is reviewing all available safety data, but at this time is not planning action to remove the drugs from the market. The FDA is highlighting safety information previously addressed by the Agency (see below), has provided other information for the consideration of clinicians in the PHA and will make further announcements or take action as warranted by the ongoing review.
