There have been a few cases of contact dermatitis and methaemoglobinaemia.
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 (0.1mg/kg i.v.) or succinylcholine chloride (10-50mg 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 Bonjela Teething Gel. Such an effect has been reported in an adult who gargled and swallowed 5 ml of a 2% Lidocaine hydrochloride solution (equivalent to 100mg of Lidocaine).However, assuming proportionality of body surface area and pharyngeal surface area, this dose would be equivalent to a single dose of 5.4 g of Bonjela Teething Gel for a three month old child.
It is most unlikely, even with misuse or excessive application of Bonjela Teething Gel, that the large amounts of Lidocaine hydrochloride or cetalkonium chloride required to produce clinically-relevant toxic effects would be reached. In the event of overdose, use should be discontinued and a doctor consulted.
ATC Code: A01AB
Lidocaine hydrochloride is an established local anaesthetic agent which produces tissue insensitivity by virtue of its ability to impede the inward flux of sodium ions, thus preventing transmission of the nerve impulse.
Cetalkonium chloride is a quatemary ammonium antimicrobial agent, being bactericidal towards both gram positive and gram negative organisms but with preference for the former.
Lidocaine is highly lipophilic resulting in rapid passage through mucous membranes, which is confirmed by human studies showing a Tmax of approximately 50 minutes following application of a 2% solution to the intact oral mucosa.
Metabolism is virtually complete by the hepatic route, undergoing three transformations, oxidative-n-dealkylation, hydrolysis and hydroxylation.
In neonates a T½ of 3-5 hours has been reported following intrathecal administration of Lidocaine to the mother; the elimination following topical application to the oral mucosa is likely to be of the same order.
No preclinical findings of relevance have been reported.
