Posology and method of administration
Route of Administration: Oromucosal
Adults, the elderly and children over 3 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.
Known hypersensitivity to anaesthetics of the amide type.
Hypersensitivity to any of the active ingredients or excipients.
Babies under 3 months.
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 three months.
Keep out of the reach and sight of children. If symptoms persist consult your doctor
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.
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.
Effects on ability to drive and use machines
Adverse reactions have been ranked under headings of frequency using the following
Very common: ≥ 1/10

Uncommon: ≥ 1/1,000 to < 1/100
Rare: ≥ 1/10,000 to <1/1,000
Very Rare: < 1/10,000
Not known: Frequency unable to be classified from available data.
Within each frequency grouping, undesirable effects are presented in order of

Methaemoglobinaemia Not known
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
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.
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.
Lidocaine is readily absorbed through the mucous membranes and is hydrolysed
mainly by the liver.
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.
