1. WHAT BONJELA IS & WHAT IT IS USED FOR
bonjela is used to
  • relieve the pain and discomfort of common mouth ulcers and cold sores.
  • aid healing of sore spots and ulcers due to dentures and braces.

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.

2. WHAT YOU NEED TO KNOW BEFORE YOU USE BONJELA

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.

Do not use if you are
  • suffering from a stomach ulcer
  • allergic to salicylates, Asprin or other NSAIDs (e.g. ibuprofen), or to any other ingredients in this product (see section 6)

Warnings and precautions

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.

Other medicines and bonjela

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.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Oral forms (e.g. tablets) of similar medicines can cause adverse effects in your unborn baby. It is not known if the same risk applies to bonjela. You should not use bonjela if you are in the last 3 months of pregnancy. You should not use bonjela during the first 6 months of pregnancy unless clearly necessary and advised by your doctor. If you need treatment during this period, the lowest dose for the shortest time possible should be used.

Important information about some of the ingredients in bonjela

This medicine contains 46.83 mg of alcohol (ethanol) in each dose. The amount in each dose of this medicine is equivalent to less than 2 ml beer or 1 ml of wine. The small amount of alcohol in this medicine will not have any noticeable effects. It may cause burning sensation on damaged skin. This medicine contains less than 1 mmol sodium (23 mg) in each dose, that is to say essentially ‘sodium-free’. This medicine contains fragrance with d-Limonene, anisyl alcohol and linalool. d-limonene, anisyl alcohol and linalool may cause allergic reactions.

3. HOW TO USE BONJELA

Always use this medicine exactly as described in this leaflet or as your doctor or pharmacist have told you.

Check with your doctor or pharmacist if you are not sure.

Mouth ulcers and sores: Using a clean finger, massage approximately one centimetre (half an inch) of bonjela onto the sore area. This can be repeated after 3 hours.

Denture sores: Massage approximately one centimetre of bonjela onto the sore area, and leave at least 30 minutes before reinserting the dentures. Do not apply bonjela directly onto the dentures.

Do not take more medicine than the label or leaflet tells you to as salicylate toxicity may occur as a result.

If your symptoms do not go away after 7 days of treatment, you should see your doctor or dentist. In the case of a missed dose, simply apply a new dose and follow the instructions described above. In the event of an overdose, seek medical advice. If you have any further questions on the use of this product, ask your doctor or pharmacist.

4. POSSIBLE SIDE EFFECTS

Like all medicines, bonjela can cause side effects, although not everybody gets them.

STOP taking this product and seek immediate medical help if you experience:
  • unexplained wheezing or coughing, asthma, shortness of breath, difficulty breathing, itching, face, tongue or throat swelling, which can be signs of serious allergic reactions.

Reporting of side effects

If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard By reporting side effects you can help provide more information on the safety of this medicine.
