Information about some of the ingredients:

This medicine contains 60 mg sorbitol in each 0.40 g dose.

This medicine contains less than 1 mmol sodium (23 mg) per 0.40 g dose, that is to say essentially 'sodium-free'.

This medicine contains 120 mg of alcohol (ethanol) in each 0.40 g dose. The amount in each 0.40 g dose of this medicine is equivalent to less than 6.0 ml beer or 2.4 ml wine.

The small amount of alcohol in this medicine will not have any noticeable effects.

4.5. Interaction with other medicinal products and other forms of interaction

No clinically significant interactions are known.

4.6. Pregnancy and lactation

The safety of this medicinal product for use in human pregnancy has not been established. Experimental animal studies are insufficient to assess the safety with respect to the development of the embryo or foetus, the course of gestation and peri- and post-natal development. The product is, therefore, not recommended during pregnancy and lactation except under medical supervision.

4.7. Effects on ability to drive and use machines

No adverse effects are known.

4.8. Undesirable effects

Occasional hypersensitivity reactions.

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 via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9. Overdose

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.
