LMX 5 (Topical application)

Lidocaine topical jelly or ointment is applied to different areas of the body to create numbness or loss of feeling for patients undergoing certain medical procedures. It is also used to ease pain and itching from conditions like sunburn or other minor burns, insect bites or stings, poison ivy, poison oak, poison sumac, minor cuts, or scratches. Xylocaine® jelly is used to treat painful urethritis (inflammation of the urethra). It is also used to prevent and control pain during procedures involving the male and female urethra. Xylocaine® jelly is also used to lubricate the nose, mouth, and throat for intubation.

Lidocaine viscous topical solution is also used to treat sore mouth or throat and to help reduce gagging during X-ray imaging and dental impressions.

Lidocaine skin patch is used to relieve nerve pain caused by herpes zoster or shingles (postherpetic neuralgia).

Lidocaine is part of a group of medicines called local anesthetics. This medicine prevents pain by blocking signals at the nerve endings in the skin. This medicine does not cause unconsciousness like general anesthetics do when used for surgery.

This medicine is available only with your doctor's prescription.

It is very important for your doctor to check you or your child's progress at regular visits to ensure this medicine is working correctly. Blood tests may be needed to look for unwanted effects.

If your symptoms do not improve within a few days or if they get worse, contact your doctor.

This medicine may cause a rare but serious blood problem called methemoglobinemia. The risk may be higher in children younger than 6 months of age, elderly patients, or patients with certain genetic conditions. It is more likely to happen in patients taking too much of the medicine, but it can also occur with small amounts. Make sure to store this medicine out of reach of children. Call your doctor immediately if you or your child has pale, gray, or blue-colored skin, lips, or nails, confusion, headache, lightheadedness, fast heartbeat, or unusual tiredness or weakness.

Contact your doctor immediately if you have a rash, burning, stinging, swelling, or irritation of your skin after using this medicine.

After applying this medicine to your child's skin, watch them closely to ensure they do not get any of the medicine into their eyes or mouth. Lidocaine can cause serious side effects, especially in children, if it gets into the mouth and is swallowed.

If you are using the viscous topical solution in the mouth or throat, be aware of signs of toxicity. If you or your child experiences unusual drowsiness, dullness, tiredness, weakness, sluggishness, shallow breathing, or seizures after using this medication, seek immediate medical attention and do not give any more doses.

If you are using this medicine in the mouth or throat, do not eat or drink anything for at least 1 hour after using it. When this medicine is applied to these areas, it may cause swallowing and choking problems. Do not chew gum or food while your mouth or throat feels numb after using this medicine. You may accidentally bite your tongue or the inside of your cheeks.

Heat can cause the lidocaine in the patch to be absorbed into your body more quickly. This may increase the chance of serious side effects or an overdose. While using this medicine, do not use a heating pad, electric blanket, heat or tanning lamps, sauna, sunlamp, or heated water bed. Do not sunbathe. However, you may apply Ztlido® patch to the skin after exposure to moderate heat (e.g., after 15 minutes of heating pad use on a medium setting).

Do not use cosmetics or other skin care products on the treated skin areas.

Do not take other medicines unless you have discussed them with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

In deciding to use a medicine, you need to consider the risks and benefits together with your doctor. Here are some important points to think about:

Allergies

Let your doctor know if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also, inform your healthcare professional about any other allergies you have, such as to foods, dyes, preservatives, or animals. For non-prescription products, carefully read the label or package ingredients.

Pediatric

This medicine can be toxic, so it should be used very carefully in children younger than 3 years old and only after other medicines have been considered or found to not work. Do not exceed the recommended doses, and the patient should be watched closely during treatment. Do not give lidocaine viscous topical solution for teething pain.

There have been no appropriate studies on how age affects the use of lidocaine jelly or skin patch in children. Safety and effectiveness have not been established.

Geriatric

Studies so far have not shown specific problems for elderly patients that would limit the use of Ztlido® skin patch. However, older adults are more likely to have liver, kidney, or heart issues due to aging, which may require careful use and possibly adjusting the dose for those taking this medicine.

There is no information available on how age affects the use of lidocaine topical in older patients. Because this medicine can be toxic, it should be used cautiously, after other medicines have been considered or found to be ineffective. Do not exceed the recommended doses, and the patient should be monitored closely during treatment.
