Viscous lidocaine is used to relieve pain and discomfort from a sore throat/mouth. It is also used to numb the lining of the mouth and throat before certain medical/dental procedures (e.g., dental impressions). This numbing helps prevent the urge to close the throat (gag reflex), which might make the procedure more difficult. Lidocaine is an amide-type local anesthetic that starts to numb the area within minutes after application.
