Symptoms of overdose include yawning, restlessness, excitement, nervousness, dizziness, nystagmus, tinnitus, blurred vision, nausea, vomiting, muscle twitching, tremors and convulsions. Excitation may be transient and followed by depression with drowsiness, respiratory failure and coma. There may be simultaneous effects on the cardiovascular system with myocardial depression and peripheral vasodilatation, resulting in hypotension, arrhythmias and cardiac arrest.
Very rarely, methaemoglobinaemia may occur with excessive exposure to some local anaesthetics. This is much more commonly seen with benzocaine and prilocaine than with lidocaine. Risk is increased in patients with hereditary methaemoglobinaemia and when used with other oxidising agents.
Treatment consists essentially of maintaining the circulation and respiration and controlling convulsions. The circulation may be maintained with infusions of plasma or suitable electrolyte solutions. Convulsions may be controlled by the intravenous administration of diazepam. If necessary, suxamethonium together with endotracheal intubation and artificial respiration may be used if convulsions persist. Methaemoglobinaemia may be treated by intravenous administration of 1-4 mg/kg methylene blue injection.

For the symptomatic relief of severe sore throats.
Lidocaine is a local anaesthetic of the amide type.
Lidocaine is readily 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.
