# Calamine Lotion ## Overview Calamine lotion is a topical protectant and antipruritic agent consisting of a mixture of zinc oxide and ferric oxide. It provides a cooling, soothing effect upon evaporation and acts as a mild astringent. ## Primary Indications * Pruritus (itching) associated with minor skin irritations (e.g., poison ivy, poison oak, poison sumac, insect bites, chickenpox). ## Adult Dosing * **Topical:** Apply a thin layer to the affected area 3 to 4 times daily as needed. Shake bottle well before each use. ## Pediatric Dosing * **Children ≥ 6 months:** Apply a thin layer to the affected area 3 to 4 times daily as needed. * **Children < 6 months:** Consult a pediatrician before use. ## Dose Adjustments * No specific systemic dose adjustments required due to lack of significant percutaneous absorption. ## Contraindications * Hypersensitivity to any component of the formulation. * Do not apply to blistered, oozing, or severely broken/raw skin without medical advice. * Avoid contact with eyes, mouth, or mucous membranes. ## Adverse Effects * **Common:** Mild stinging upon application, skin dryness, local irritation. * **Rare:** Contact dermatitis or hypersensitivity reaction (rash, swelling, persistent itching). ## Key Drug Interactions * None significant due to minimal systemic absorption. ## Monitoring * Monitor for signs of secondary skin infection (increasing redness, pus, warmth). * Assess for resolution of pruritus; if symptoms persist beyond 7 days or worsen, discontinue and consult a healthcare provider. ## Clinical Pearls * **Application:** Always shake the bottle vigorously until the suspension is uniform. The pink color is characteristic of the ferric oxide content. * **Removal:** It can be washed off with warm water and soap; do not scrub the skin aggressively. * **Safety:** For external use only. Keep out of reach of children to prevent accidental ingestion. * **Uncertainty:** Dosing frequency may be increased based on institutional protocols for specific dermatological conditions, but generally should not exceed 4 applications daily to prevent excessive skin drying. *** *Disclaimer: This information is for educational purposes and does not supersede local prescribing protocols or manufacturer-provided product inserts.
