This medication is a nasal spray used to cause numbness in your mouth before dental procedures on certain teeth. It contains 2 ingredients: tetracaine and oxymetazoline. Tetracaine is a local anesthetic that works by blocking nerves, which causes temporary numbness of the area. Oxymetazoline works by narrowing blood vessels in the nose area, which helps the tetracaine work better.

How to use

This medication is given as directed by your dental professional, usually 2 sprays into the nose on the same side as the tooth on which the dental procedure will be done. The 2 sprays are usually given 4 to 5 minutes apart. Your dentist may test drill the tooth to check if you are numb. One more spray may be given if the area is not numb 10 minutes after the second spray.
