Symptoms
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, muscular tremors, convulsions, coma, irregular and weak breathing, cardiac standstill, bronchial spasm, severe hypotension, asystole, bradycardia, apnoea, seizures, coma, cardiac arrest, respiratory arrest, and death.
