# Calamine Lotion ## Overview Calamine lotion is a topical preparation containing zinc oxide and ferric oxide (or calamine powder, a mixture of zinc oxide, iron(III) oxide, and sometimes calcium hydroxide). It acts as a mild astringent and antipruritic. ## Primary Indications * Relief of itching and irritation associated with minor skin irritations, insect bites, poison ivy/oak/sumac, sunburn, and eczema. ## Adult Dosing Apply to the affected area as needed, typically 3-4 times daily. Shake well before use. ## Pediatric Dosing Apply to the affected area as needed, typically 3-4 times daily. Shake well before use. Dosing is generally the same as adults, but caution is advised for large surface area application in infants due to potential for absorption. ## Dose Adjustments No dose adjustments are typically required. ## Contraindications * Hypersensitivity to any component of the preparation. * Avoid application to severely excoriated or infected skin unless directed by a healthcare professional. ## Adverse Effects * Skin irritation, dryness, or allergic reactions are uncommon. * Ingestion can cause gastrointestinal upset (nausea, vomiting, constipation). ## Key Drug Interactions None established for topical use. Oral ingestion of large quantities may interact with other medications, but this is rare. ## Monitoring * Monitor for signs of skin irritation or allergic reaction. * If symptoms do not improve after 7 days or worsen, discontinue use and consult a healthcare professional. ## Clinical Pearls * Shake lotion well before each application to ensure proper mixing of ingredients. * For external use only.
