As with any local anaesthetic, reactions and complications are best averted by employing the minimal effective dosage. Debilitated or elderly patients and children should be given doses commensurate with their age and physical condition.
Lidocaine Spray should not be used on cuffs of endotracheal tubes (ETT) made of plastic (see also section Special warnings and precautions for use).
Each activation of the metered dose valve delivers 5.7 – 9.3 mg lidocaine base. It is unnecessary to dry the site prior to application. No more than 20 spray applications should be used in any adult to produce the desired anaesthetic effect.
The number of sprays depend on the extent of the area to be anaesthetised.

1–5 applications to the mucous membranes.
Otorhinolaryngology
3 applications for puncture of the maxillary sinus.
During delivery
Up to 20 applications.
