Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of lidocaine and prilocaine topical cream in children. However, because of this medicine's toxicity, it should be used with caution, after other medicines have been considered or found ineffective. Recommended doses should not be exceeded, and the patient should be carefully monitored during therapy.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of lidocaine and prilocaine topical cream in the elderly.
