This medicine may cause a rare, but serious blood problem called methemoglobinemia. The risk may be increased in children younger than 6 months of age, elderly patients, or patients with certain inborn defects. It is more likely to occur in patients receiving too much of the medicine, but can also occur with small amounts. Make sure you store this medicine out of reach of children. Call your doctor right away 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.
Check with your doctor right away if you have a rash, burning, stinging, swelling, or irritation of your skin after using this medicine.
After applying this medicine to the skin of your child, watch the child carefully to make sure that he or she does 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 medicine in the mouth or throat, be aware of signs of toxicity. If you or your child experiences unusual drowsiness, dullness, tiredness, weakness, or feeling of sluggishness, shallow breathing, or seizures after use of 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 you use 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 faster. This may increase the chance of serious side effects or an overdose. While you are using this medicine, do not use a heating pad, electric blanket, heat or tanning lamps, sauna, a sunlamp, or a heated water bed. Do not sunbathe. However, you may apply Ztlido® patch on the skin after exposure to moderate heat (eg, 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 they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
