Hi all! I have heard that Lysopaine - the cough medicine is banned to sell in Vietnam. Can anyone tell me there are any harmful ingredients in Lysopaine?

A reported ingredient in Lysopaine is cetylpyridinium chloride for which reported side effects include:

Irritation and Rashes
According to “Secret Gateway to Health,” low doses of cetylpyridinium chloride can cause skin irritation, rashes and a burning sensation in the mouth. It also can cause minor throat and mouth irritation, according to “Modell's Drugs in Current Use and New Drugs.” Cetylpyridinium chloride also can irritate the eyes, stomach and gastrointestinal tract.

Teeth Staining
According to “Natural Cures for Common Conditions,” dental products containing cetylpyridinium chloride can discolor teeth. Eating ripe strawberries, using baking soda and increasing water intake can manage CPC staining. Other remedies include rubbing glycerin and lemon on the teeth and rinsing the teeth thoroughly with water after eating or brushing.

Vomiting and Nausea
Oral products using cetylpyridinium chloride, such as lozenges and toothpaste, can cause vomiting and nausea.

Lung Damage, Oral Numbness and Allergies
Cetylpyridinium chloride can make your mouth or throat numb. Products with cetylpyridinium chloride as the active ingredient, increase the risk of severe allergic reactions, such as swelling of the mouth, face, lips or tongue, labored breathing, rashes, and hives.
