Pharmacologic Category
EENT Preparations; Local Anesthetics. Antipruritics and Local Anesthetics (Topical). (ATC-Code: C05AD03; D04AB04; N01BA05; R02AD01).
Mechanism of action
Ester local anesthetic decreases the neuronal membrane’s permeability to sodium ions and so inhibits depolarization, blocking both initiation and conduction of nerve impulses.
Therapeutic use
Temporary relief of pain associated with pruritic dermatosis, pruritus, minor burns, bee stings, and insect bites, mouth and gum irritations (toothache, minor sore throat pain, canker sores, dentures, orthodontia, teething, mucositis, stomatitis). Sunburn. Hemorrhoids. Anesthetic lubricant for passage of catheters and endoscopic tubes.
Pregnancy and lactiation implications
Reproduction studies have not been conducted. Use cautiously during pregnancy and lactation.
Unlabeled use
Contraindications
Hypersensitivity to benzocaine, other ester-type local anesthetics, or any component of the formulation. Secondary bacterial infection of area. Ophthalmic use.
Warnings and precautions
Methemoglobinemia may occur following topical use, particularly with higher concentration spray formulations applied to the mouth or mucous membranes (caution with breathing problems, inflamed/damaged mucosa, heart disease, children <6 months of age, and hemoglobin or enzyme abnormalities (glucose-6-phosphodiesterase deficiency, hemoglobin-M disease, NADH-methemoglobin reductase deficiency, pyruvate-kinase deficiency)). Do not use on open wounds.
