Lidocaine spray is used to numb the lining of the mouth and throat before certain medical procedure (e.g., intubation). It is a local anesthetic that starts to numb the lining of the mouth and throat 1-2 minutes after application. It also helps prevent the urge to close the throat (gag reflex), which might make the procedure more difficult.

Not applicable.

This medication is usually sprayed within the mouth by a health care professional immediately before your procedure. This medication numbs the nose and throat. This will make swallowing difficult and increase your risk of choking or swallowing the wrong way. Do not eat or chew gum for 1 hour after this product is used or until your mouth/throat is no longer numb. It is especially important to make sure children do not eat or chew gum for at least 1 hour after their procedures. Be careful not to accidentally bite your tongue or mouth.

Lidocaine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using lidocaine, tell your doctor or pharmacist if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death). Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting.
