# Calamine Lotion ## Overview Calamine lotion is a topical protectant and antipruritic agent usually consisting of zinc oxide (active) and ferric oxide (coloring agent). It acts as a mild astringent and skin-soothing agent. ## Primary Indications * Relief of itching, pain, and discomfort associated with minor skin irritations (e.g., poison ivy, poison oak, poison sumac, insect bites, prickly heat, rashes). ## Adult Dosing * **Topical:** Shake bottle well before use. Apply a thin layer to the affected area 3 to 4 times daily as needed. ## Pediatric Dosing * **Children (>6 months):** Same as adult dosing. * **Infants (<6 months):** Use only under the guidance and supervision of a pediatrician. ## Dose Adjustments * No systemic dose adjustments required due to poor percutaneous absorption. ## Contraindications * Hypersensitivity to any component of the formulation. * Do not apply to deep puncture wounds, animal bites, or serious burns. * Avoid contact with eyes, mucous membranes, or genital areas. ## Adverse Effects * **Local:** Minor skin irritation, dryness, or contact dermatitis upon prolonged use. * **Rare:** Allergic reactions (rash, itching, swelling). ## Key Drug Interactions * No significant clinical drug-drug interactions due to minimal systemic absorption. * Avoid concurrent application of other topical medications to the same site unless directed by a provider, as calamine may act as a barrier and impede absorption. ## Monitoring * Monitor for signs of secondary bacterial infection (e.g., pus, spreading redness, warmth, fever). * Monitor for worsening irritation or if the condition persists beyond 7 days of treatment. ## Clinical Pearls * **Sedimentation:** Calamine lotion naturally settles; shaking vigorously before every application is essential to ensure a uniform concentration of zinc oxide. * **Drying Effect:** Excessive application can lead to over-drying of the skin; discontinue use if the skin becomes excessively cracked or irritated. * **Inhalation Risk:** Instruct patients/caregivers to avoid intentional inhalation of the aerosolized mist if using a spray formulation. * **Staining:** Contains iron oxide (ferric oxide), which can stain fabrics. *** **Educational Disclaimer:** This information is for educational purposes only.
