Mouth pain is a common problem these days and there are many people who are suffering from this issue.

However, a common misconception people have is that mouth pain is caused because of toothache or a problem in the gums. What they do not know that there are various other reasons behind the cause of mouth pain and one of them is canker sores.

Canker sores

Canker sores are commonly known as mouth ulcers that develop in the soft tissues of the mouth.

Canker sores can be caused due to emotional stress or toothpaste/mouthwash which contains sodium lauryl sulfate and bacterial reactions. 

If you do not treat canker sores properly you might find it difficult to eat or talk.

What is KANKA?

Kanka also known as Kank-a is a medicated liquid prepared with enzymes and minerals. There is a special type of ingredient named benzocaine in it.

1. Can Cause Methemoglobinemia

Methemoglobinemia is a condition in which oxygen doesn’t reach the tissues on certain parts of the body, and this dangerously low amount of oxygen can bring fatal problems to certain parts of your skin.

So, the first side effect or drawback of Blistex Kanka Mouth Pain Liquid is that it may cause Methemoglobinemia.

Some symptoms related to Methemoglobinemia are a headache, tired feeling, tension, confusion, fast heart rate, and sensing light-headed or short-breath. It can also cause a blue, pale, or gray appearance on your skin around the lips and/or fingernails. If you find any such sort of issues on your skin or experience the aforementioned products, contact your nearest doctor immediately.

2. Overdose Can Cause Serious Problems

Although it is an oral medicine, your body absorbs it. If you apply more than the recommended dosage on the affected area, then the tissues of your body will start to absorb that higher amount of medicine.

This can cause the medicine to get into your bloodstream which can lead to more serious health problems.
