# Calamine Lotion ## Overview Calamine lotion is a topical protectant and antipruritic combination product consisting primarily of zinc oxide (white) and ferric oxide (pink). It provides a cooling, soothing effect upon evaporation and is intended for external use only. ## Primary Indications * Relief of pruritus (itching) associated with minor skin irritations (e.g., poison ivy, poison oak, poison sumac). * Temporary relief of rashes due to insect bites, dermatitis, or chickenpox. ## Adult Dosing * **Topical:** Shake well before use. Apply a thin layer to the affected area using a cotton ball or soft cloth. * **Frequency:** May be applied 3 to 4 times daily as needed. ## Pediatric Dosing * **Age <6 months:** Consult a pediatrician; generally not recommended without medical supervision due to risk of ingestion and lack of safety data. * **Age ≥6 months:** Same as adult dosing. Use sparingly and ensure the child does not ingest the product. ## Dose Adjustments No specific dosage adjustments are required. Use is limited by the surface area affected; avoid application to extensive body surface areas (BSA) or open, oozing wounds unless directed by a clinician. ## Contraindications * Hypersensitivity to any component (e.g., zinc oxide, ferric oxide, or preservatives). * Do not apply to eyes, mouth, or mucous membranes. * Do not apply to deeply punctured or infected wounds. ## Adverse Effects * **Dermatologic:** Drying of the skin, contact dermatitis (rare), or irritation from prolonged use. * **Systemic:** Generally negligible due to poor systemic absorption; however, toxic ingestion of large quantities can lead to gastrointestinal distress. ## Key Drug Interactions * No significant systemic drug interactions are recognized due to minimal absorption. * Avoid applying other topical medicaments simultaneously to the same site to ensure absorption of the primary medication. ## Monitoring * **Efficacy:** Monitor for reduction in pruritus. * **Safety:** Monitor for worsening of skin condition, signs of secondary infection (e.g., pus, spreading redness, fever), or allergic reaction. Discontinue if redness persists or worsens after 7 days. ## Clinical Pearls * **Shake Well:** The components settle; shake vigorously to ensure a uniform suspension before every application. * **Drying Agent:** Excessive use may cause the skin to become overly dry or cracked. * **Infection Risk:** Do not apply to weeping or severely blistered lesions without clinical guidance, as the film may trap bacteria if not applied correctly. * **Ingestion:** Keep out of reach of children; ingestion of the zinc/iron components can be harmful. *** *Disclaimer: This information is for educational purposes only.
