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

Hypersensitivity to lidocaine or to any of the excipients listed in section 6.1.

Known hypersensitivity to local anaesthetics of the amide type.

Babies under 5 months.

In patients who have a history of or are suspected to have methaemoglobinaemia (see section 4.8).

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.

Excessive dosage, short intervals between doses or use on traumatised mucosa may result in high plasma levels and serious adverse effects (see Section 4.9).

Warnings related to Excipients:

This medicine contains 242.2 mg of alcohol (ethanol) per 1g. The amount in each 1g of this medicine is equivalent to less than 7 ml beer or 3 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 1g, that is to say essentially 'sodium-free'.

This medicine contains fragrance with Eugenol. Eugenol may cause allergic reactions.

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.

Lidocaine should be used with caution in patients receiving other local anaesthetics or agents structurally related to amide-type local anaesthetics, e.g. antiarrhythmic drugs such as mexiletine, since the toxic effects may be additive.

In patients taking erythromycin the toxicity of oral lidocaine may be increased.

In patients taking itraconazole, the toxicity of oral lidocaine may be increased.

4.6 Fertility, pregnancy and lactation


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


Lidocaine enters breast milk, but in such small quantities there is generally no risk of the child being affected at therapeutic dose levels.

No adverse effects have been seen in breastfed infants whose mothers were receiving lidocaine and it is therefore usually compatible with breast feeding.


No data on human fertility are available.

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, muscular tremors, convulsions, coma, irregular and weak breathing, cardiac standstill, bronchial spasm, severe hypotension, asystole, bradycardia, apnoea, seizures, coma, cardiac arrest, respiratory arrest, and death.


In the unlikely event of overdose with this product, immediate treatment should be sought which should be symptomatic and supportive.

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.
