# Calamine Lotion ## Overview Calamine lotion is a topical protectant and antipruritic composed primarily of zinc oxide and ferric oxide. It acts as a soothing agent that provides a cooling sensation upon evaporation and serves as a mild astringent for minor skin irritations. ## Primary Indications * Relief of pruritus (itching) due to poison ivy, poison oak, poison sumac, insect bites, or minor skin irritations. ## Adult Dosing * **Topical:** Apply a thin layer to the affected area 3–4 times daily, or as needed. * **Maximum Dose:** No specific systemic maximum; use sparingly to avoid excessive drying or caking on the skin. ## Pediatric Dosing * **Pediatric (6 months and older):** Apply to affected areas 3–4 times daily. * **Infants (<6 months):** Consult a pediatrician prior to use. * **Note:** Use cautiously to prevent accidental ingestion or inhalation of vapors. ## Dose Adjustments * **Renal/Hepatic:** No adjustments necessary; negligible systemic absorption. * **Geriatric:** No specific adjustments, though skin may be thinner/more prone to dryness. ## Contraindications * Hypersensitivity to zinc oxide, ferric oxide, or any component of the formulation. * Do not apply to blistered, raw, or oozing skin surfaces unless directed by a healthcare provider. ## Adverse Effects * **Dermatologic:** Skin dryness, irritation, or contact dermatitis with prolonged use. * **Systemic:** Generally none, provided the product is not ingested. ## Key Drug Interactions * Minimal interactions due to lack of systemic absorption. * Avoid applying other topical medicated products (e.g., corticosteroids) simultaneously, as the lotion may form a barrier that potentially alters drug absorption. ## Monitoring * Monitor treated area for signs of worsening irritation, infection (erythema, warmth, pus), or failure to improve after 7 days. ## Clinical Pearls * **Shake well:** Calamine lotion is a suspension that settles; thorough agitation is required before each application to ensure uniform concentration. * **Drying effect:** The lotion can be excessively drying; discontinue use if skin becomes overly cracked or irritated. * **Ingestion risk:** Keep out of reach of children. If swallowed, contact a Poison Control Center immediately. * **Cosmetic:** Leaves a pink, chalky residue that may stain clothing. *** **Educational Disclaimer:** This information is for educational purposes only.
