It is a topical anesthetic. ## Primary Indications * Relief of pain and itching associated with minor skin irritations, such as sunburn, insect bites, or minor cuts and scrapes. * Topical pain relief for hemorrhoids. ## Adult Dosing Apply a thin layer to the affected area as needed, typically up to 3-4 times daily. Do not apply over large areas of broken skin or for prolonged periods without medical advice. Specific dosing for rectal application (e.g., for hemorrhoids) may vary; follow product labeling or physician instructions. ## Pediatric Dosing Safety and efficacy in pediatric patients are not well-established for all indications. For minor skin irritations in children, use may be guided by product labeling or physician discretion. Benzocaine products are not recommended for infants under 2 years of age due to the risk of methemoglobinemia. ## Dose Adjustments No specific dose adjustments are typically required for renal or hepatic impairment, but absorption can be increased with damaged skin, potentially leading to systemic effects. ## Contraindications * Hypersensitivity to tetracaine, benzocaine, or other PABA (para-aminobenzoic acid) derivatives. * Infants under 2 years of age for benzocaine-containing products. * Avoid use on large areas of broken skin or wounds. ## Adverse Effects Common: Localized burning, stinging, redness, or rash at the application site. Serious: * **Methemoglobinemia:** Especially with benzocaine, particularly in infants and with overuse. Symptoms include cyanosis, headache, fatigue, shortness of breath, and dizziness. * Allergic reactions: Rash, itching, swelling, severe dizziness, trouble breathing. * Systemic toxicity (rare with topical use but possible with excessive absorption): Central nervous system effects (e.g., excitation, seizures) and cardiovascular effects. ## Key Drug Interactions * **Sulfonamides:** Benzocaine may antagonize the antibacterial effect of sulfonamides. * **MAO Inhibitors and Tricyclic Antidepressants:** Concurrent use with agents that affect serotonin levels may increase the risk of serotonin syndrome. * **Cholinergic drugs:** Reduced efficacy. * **Metoclopramide:** Increased risk of methemoglobinemia. ## Monitoring * Monitor for signs of allergic reaction. * Monitor for signs and symptoms of methemoglobinemia, especially in infants and with extensive use (e.g., cyanosis, dyspnea). ## Clinical Pearls * These agents are intended for short-term use. * Avoid contact with eyes. * Do not apply to mucous membranes. * The risk of methemoglobinemia is increased with application to large surface areas, broken skin, or prolonged duration of use. *** **Disclaimer:** This information is intended for healthcare professionals and is not a substitute for current prescribing information.
