Bonjela is an over-the-counter medication that those can use over the age of 16 to relieve pain, discomfort, and inflammation caused by mouth ulcers. It can also be used to treat pain in the mouth caused by other conditions, such as cold sores and sore spots from dentures and braces.

Who is it for?

Bonjela (adult and cool mint varieties) can be used by patients over 16. For patients below the age of 16, Bonjela soothing teething gel should be used instead.

How does it work?

Bonjela contains two active ingredients, the antiseptic cetalkonium chloride, which helps fight infections, and choline salicylate, which helps relieve pain caused by inflammation. Bonjela has broad-spectrum antimicrobial properties alongside its anti-inflammatory and painkilling properties.

Should anyone avoid taking it?

No one below the age of 16 should use adult formulations. You should also not use Bonjela if you suffer from a stomach ulcer. If you are pregnant, consult your doctor or pharmacist before using the gel.

Are there any side-effects?

As with any medication, some people are bound to get some unwanted side effects. Some common ones include coughing, wheezing, shortness of breath, itching, and swelling of the face, tongue, or throat.

If you have shortness of breath, swelling of the mouth or tongue, or breathing difficulty and think this could be a severe allergic reaction, you should call 911.
