Drug

Lidocaine HCl

Pronounced

"LIE-doh-cane"

Uses

Lidocaine spray is used to numb the lining of the mouth, throat, or nose before certain medical/dental procedures. It also 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.

How to Use This Medication

Read the Patient Information Leaflet if available from your pharmacist before you start using lidocaine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

This medication is usually sprayed in the mouth by a health care professional as directed by your doctor right before your procedure.

The dosage is based on your medical condition and response to treatment. Children's dosage is also based on age and weight.

Numbness may make swallowing difficult and increase your risk of swallowing the wrong way or choking. Do not chew gum or eat for 1 hour after using this product and while your mouth or throat is numb. It is especially important for children to not eat or chew gum for at least 1 hour after their procedures. Be careful not to accidentally bite your tongue or mouth.

Lidocaine starts to numb the affected area within 5 minutes after application. Tell your doctor if the area does not feel numb or the numbness does not go away.
