bonjela is a clear, almost colourless gel, which is applied to the inside of the mouth or gums. It contains choline salicylate (a pain killer and anti-inflammatory) which soothes sore areas in the mouth and an antiseptic called cetalkonium chloride, which kills bacteria and helps prevent infection.
bonjela is intended for adults and children over the age of 16.
Do not give to children or adolescents under 16 years of age. This is because there is a possible link between salicylates and Reye’s syndrome when given to children. Reye’s syndrome is a very rare disease which affects the brain and liver and can be fatal.

- allergic to salicylates, Asprin or other NSAIDs (e.g. ibuprofen), or to any other ingredients in this product (see section 6)
This product contains salicylates. Talk to your doctor, dentist or pharmacist before taking this product with Aspirin or other salicylates. Talk to your doctor or dentist if you have an active or recurring stomach ulcer.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Salicylates may increase the effect of blood thinning medicines (anticoagulants) and can decrease the effect of medicines to treat gout (uricosurics) such as probenic acid, benzbromarone.
