Uses

See also Warning section.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 (such as dental impressions). This numbing helps prevent the urge to close the throat (gag reflex), which might make the procedure more difficult. Lidocaine belongs to a class of drugs known as local anesthetics.
