Reporting of suspected adverse reactions

Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard.
Overdosage with this product is unlikely to constitute a hazard and therefore symptomatic treatment only is necessary.
Lidocaine is a local anaesthetic of the amide type. Cetylpyridinium chloride is a cationic antiseptic.
Lidocaine is rapidly absorbed from mucous membranes. The plasma elimination half life is about two hours.
Lidocaine undergoes significant first pass metabolism in the liver and is rapidly de-ethylated to the active metabolite monoethylglycinexylidide and then hydrolysed to various metabolites including glycinexylidide. Less than 10% is excreted unchanged by the kidneys. The metabolites are also excreted in the urine.
