Xylocaine MM Warnings
Xylocaine MM Uses
This medication is used to prevent and control pain during certain medical procedures such as inserting a tube into the mouth, nose, throat, or urinary tract (e.g., endotracheal intubation, urinary catheterization). Lidocaine jelly is also used to numb and treat inflammation of the urinary tract (urethritis). Lidocaine is a topical anesthetic that numbs mucus membranes. It does not work to numb thicker skin.How to use Xylocaine MM
This medication is usually applied by a health care professional to the area being treated or to the medical equipment as part of a medical procedure. It is applied at the start of the procedure and takes 3-5 minutes for the numbing effect to occur. If using this medication for urinary procedures (e.g., cystoscopy), follow the package instructions for sterilizing and using the applicator cone if one is provided. Discard any unused jelly after first use.
If you are using this medication at home (such as for inserting a catheter yourself), read and learn all preparation and usage instruction from the manufacturer. Follow your doctor's directions closely. Avoid getting this medication in your eyes. Do not use more than 4 doses in 24 hours. Do not increase your dose or use this medication more often than prescribed without your doctor's approval. Doing so can increase the risk of very serious side effects. Use proper sterile technique. Ask your health care professional if you have any questions about how to use this medication or perform your medical procedure.
If used in the mouth or throat, avoid eating or chewing gum for at least 1 hour after use. The risk of choking or biting the tongue or cheek is greater when the mouth, tongue, or throat are numb.

Xylocaine MM Precautions
Before using lidocaine, tell your doctor or pharmacist if you are allergic to it; or to other anesthetics (e.g., bupivacaine, prilocaine); or to PABA; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: bites/cuts/scrapes/sores in the area to be treated, heart problems (e.g., irregular heartbeat), severe infection with high fever (e.g., sepsis), liver disease.
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 need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using lidocaine, tell your doctor or pharmacist of all the drugs you take and 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. Talk to your doctor about using lidocaine safely.
To minimize dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.
Older adults may be more sensitive to the side effects of this drug, especially heart effects such as QT prolongation (see above).
Caution is advised when using this drug in children because they may be more sensitive to the effects of the drug, especially drowsiness.
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is not known if this medication passes into breast milk. Consult your doctor before breast-feeding.
Xylocaine MM Interactions
Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with them first.
Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use.
Many drugs besides lidocaine may affect the heart rhythm (QT prolongation), including amiodarone, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), among others. Therefore, before using lidocaine, report all medications you are currently using to your doctor or pharmacist.
Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as: certain antihistamines (e.g., diphenhydramine), anti-seizure drugs (e.g., carbamazepine), medicine for sleep or anxiety (e.g., alprazolam, diazepam, zolpidem), muscle relaxants, narcotic pain relievers (e.g., codeine), psychiatric medicines (e.g., chlorpromazine, risperidone, amitriptyline, trazodone).
Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain drowsiness-causing ingredients. Ask your pharmacist about using those products safely.
This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
