Benzocaine spray - mucous membrane
Benzocaine spray - mucous membrane
Benzocaine spray is used to numb the lining of the mouth and throat before certain medical procedures (e.g., intubation). It is also used to temporarily relieve pain from minor mouth/throat problems (e.g., sore throat, canker sores, minor dental procedures, mouth/gum injury). It is also used to decrease pain while dentures are being fitted and while your gums are adjusting to the dentures. It should not be used long-term to decrease pain from poorly fitting dentures. It is a local anesthetic that starts to numb the lining of the mouth and throat 15 to 30 seconds after application and lasts about 15 minutes.
