Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Because of this medicine's toxicity, it should be used with extreme caution in children younger than 3 years of age, only after other medicines have been considered or found ineffective. Recommended doses should not be exceeded, and the patient should be carefully monitored during treatment. Do not give lidocaine viscous topical solution for teething pain.

Appropriate studies have not been performed on the relationship of age to the effects of lidocaine jelly or skin patch in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of Ztlido™ skin patch in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

No information is available on the relationship of age to the effects of lidocaine topical in geriatric patients.
