Introduction: The use of topical anesthetics, has increased in recent years.While they are undoubtedly useful when recommended appropriately by a dermatologist, the improper use of topical anesthetics may result in complications, mainly due to inadequately applying them to wounded or inflamed skin; use on large areas of the body or mucus membranes; or use by high-risk patients. Adverse reactions can include transient local effects, allergic and/or irritative reactions, or more severe (though rare) effects, such as methemoglobinemia, arrhythmias, and cardiorespiratory failure. This paper discusses the commercial formulations of topical anesthetics currently available, their history, pharmacology, clinical use, and potential side effects.
