This information is intended for use by health professionals

1. Name of the medicinal product

Bonjela Junior gel

2. Qualitative and quantitative composition

Lidocaine hydrochloride 0.5% w/w

Cetylpyridinium chloride 0.025% w/w

For a full list of excipients, see section 6.1.

3. Pharmaceutical form

Oromucosal gel

4. Clinical particulars
4.1 Therapeutic indications

For the relief of pain from common mouth ulcers and denture irritation.

4.2 Posology and method of administration

Route of Administration: Oromucosal

Adults, the elderly and children over 5 months:

Apply a little gel to the sore area with either a clean finger tip or swab. This may be repeated after twenty minutes and then every three hours.

4.3 Contraindications

Known hypersensitivity to anaesthetics of the amide type.

Hypersensitivity to any of the active ingredients or excipients.

Babies under 5 months.

4.4 Special warnings and precautions for use

To be used with caution in patients with hepatic or cardiac dysfunction.

Do not exceed the stated dose. Not recommended for infants under five months. Keep out of the reach and sight of children. If symptoms persist consult your doctor or dentist.

Not suitable for treatment of teething in children.

4.5 Interaction with other medicinal products and other forms of interaction

Concurrent use of either cimetidine or propranolol increases the risk of lidocaine toxicity. Lidocaine is antagonised by those diuretics which cause hypokalaemia.

4.6 Fertility, pregnancy and lactation


The safety of the product for use in human pregnancy has not been established. The product is, therefore, not recommended during pregnancy.


Lidocaine is distributed into breast milk, but in such small quantities that there is generally no risk of the child being affected at therapeutic dose levels. No adverse effects have been seen in breast-fed infants whose mothers were receiving lidocaine and it is therefore usually compatible with breast feeding.


No data on human fertility are available.

4.8 Undesirable effects

Adverse reactions have been ranked under headings of frequency using the following convention:

Very common: ≥ 1/10

Reporting of Suspected Adverse Reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Overdose is highly unlikely given the size of the pack. No experience of overdosage.

It is most unlikely, even with misuse or excessive application of the gel, that the large amounts of lidocaine hydrochloride or cetylpyridinium chloride required to produce clinically-relevant toxic effects would be reached. In the event of overdose, use should be discontinued and a doctor consulted.

The toxic effects of lidocaine are directly related to blood concentrations. Symptoms are dizziness, cyanosis due to methaemoglobinaemia, fall of blood pressure, muscular tremors, convulsions, coma, irregular and weak breathing, cardiac standstill and bronchial spasm. Removal of the ingested drug by induced emesis followed by activated charcoal is only useful if the patient is seen within 30 minutes of ingestion. The airway must be maintained and artificial respiration with oxygen given until convulsions or depression are controlled and blood pressure and pulse return to normal.

Convulsions can be controlled with diazepam (0.1 mg/kg i.v.) or succinylcholine chloride (10-50 mg i.v. slowly). Perform artificial respiration with oxygen until convulsions are controlled and continue giving oxygen until blood pressure and pulse return to normal. Adequate arterial oxygen saturation must be maintained. If convulsions are not continuous the administration of oxygen may be sufficient to maintain the patient until the blood level of lidocaine falls. Do not give stimulants. The methaemoglobinaemia can be treated by methylene blue (1%, 0.1 ml/kg, i.v. over ten minutes). Treat fall in blood pressure by postural means (head down, feet raised, supine position) or with i.v. saline or blood transfusion if shock threatens. The critical period does not exceed one hour.

Suppression of pharyngeal sensation with concomitant effects on swallowing may theoretically result from excessive topical oral use of the gel. Such an effect has been reported in an adult who gargled and swallowed 5 ml of a 2% lidocaine hydrochloride solution (equivalent to 100 mg of lidocaine). However, assuming proportionality of body surface area and pharyngeal surface area, this dose would be equivalent to a single dose of 3.6 g of the gel for a three month old child.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Lidocaine, combinations; ATC Code: N01BB52

Lidocaine is a local anaesthetic of the amide type, acting to produce reversible loss of sensation by preventing or diminishing the generation and transmission of sensory nerve impulses near the site of application. Depolarisation of the neuronal membrane and ion exchange are reversibly inhibited.

Cetylpyridinium chloride is a quaternary pyridinium antiseptic with actions and uses similar to those of other cationic surfactants.

5.2 Pharmacokinetic properties

Lidocaine is readily absorbed through the mucous membranes and is hydrolysed mainly by the liver.

5.3 Preclinical safety data

There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
