4.7 Effects on ability to drive and use machines
No effect on subjects’ ability to drive or operate machines.
4.8
Undesirable effects
Application of benzocaine on skin and mucous membranes has resulted in hypersensitivity reactions (burning, stinging, pruritis, erythema, rash and oedema), contact dermatitis and methaemoglobinaemia in a few cases in infants, children and adults.
If symptoms persist, or are severe, or are accompanied by fever, headache, breathlessness, nausea and vomiting, consult a doctor.
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 the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
4.9 Overdose
Excessive absorption of benzocaine may produce methaemoglobinaemia in infants, children, and adults. The first clinical signs are cyanotic (greyish) skin discolouration (most notably on mucous membranes) and signs of unusual breathing or breathlessness.
Methaemoglobinaemia may be treated by the intravenous administration of 1% methylene blue. Treatment of overdose should be symptomatic and supportive.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Local anaesthetics, ATC code: N01BA05
Benzocaine is a local anaesthetic of the ester type with rapid onset, 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.
5.2 Pharmacokinetic properties
Benzocaine is absorbed through mucous membranes and damaged skin. Anaesthetics of the ester type are hydrolysed by esterases in the plasma and, to a lesser extent, in the liver.
Preclinical safety data
5.3
There are no additional pre-clinical data of relevance to the prescriber.
