Lidocaine HCl / Tetracaine HCl Cream
Overview
Lidocaine / Tetracaine Cream is a combination of prescription drug products that are commonly used topically as local anesthetics prior to minor dermatological procedures (e.g., Botox® injections, chemical peels, dermabrasion, facial fillers, laser hair removal, microneedling).
Lidocaine
Lidocaine is a commonly used topical anesthetic, with an onset of action of about four minutes. It works by blocking sodium channels to stop local neurons from signaling the brain.
Tetracaine
Tetracaine is another topical anesthetic. It is longer acting but also takes longer to work than lidocaine. It works by changing the function of ryanodine receptors that control the release of intracellular calcium.
This preparation is intended for the short-term topical use to small areas of in-tact skin. It should not be used in anyone with ester local anesthetic hypersensitivity or para-aminobenzoic acid, PABA hypersensitivity. The preparation is also contraindicated for use in patients with cholinesterase and pseudocholinesterase deficiencies. Lidocaine / Tetracaine Cream should not be occluded or applied to large areas of inflamed tissue (e.g., abrasions, atrophy, burns) since systemic absorption or toxicity can occur. Care should be taken to ensure the maximum dose of Lidocaine / Tetracaine Cream is not exceeded during application. For these reasons, this formulation best administered under professional supervision by a healthcare practitioner prior to dermatologic procedure.1-7
