What is KANK-A?
KANK-A Mouth Pain Liquid contains benzocaine, a local anesthetic (numbing medication). It works by blocking nerve signals in your body.
KANK-A Mouth Pain Liquid numbs surfaces inside the mouth and is used for treating canker sores and other oral abrasions.
KANK-A should not be used to treat teething pain in infants, and is not approved for use in a child younger than 2 years old.
Warnings
KANK-A 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 KANK-A can cause fatal side effects if too much of the medicine is absorbed through your oral membranes and into your blood. Use the smallest amount needed.
Do not use KANK-A on a child younger than 2 years old.
Before taking this medicine
Do not use KANK-A if you have ever had methemoglobinemia in the past.
An overdose of benzocaine can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This can happen if you apply more than the recommended dose.
Fatal overdoses have occurred when numbing medicines were used 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 KANK-A is safe to use if you have:
a personal or family history of methemoglobinemia, or any genetic (inherited) enzyme deficiency;
heart disease; or
if you smoke.
Ask a doctor before using this medicine if you are pregnant or breast-feeding.
If you apply KANK-A to your chest, avoid areas that may come into contact with the baby's mouth.
How should I use KANK-A?
Use KANK-A exactly as directed on the label, or as prescribed by your doctor. Read all medication guides or instruction sheets.
Your body may absorb more benzocaine 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 me...
