# Calamine Lotion ## Overview Calamine lotion is a topical dermatological agent composed primarily of zinc oxide and ferric oxide (which provides the characteristic pink color). It functions as a skin protectant and mild astringent, providing a cooling and soothing effect upon evaporation. ## Primary Indications * Relief of pruritus (itching) associated with minor skin irritations (e.g., poison ivy, poison oak, poison sumac, insect bites, chickenpox). ## Adult Dosing * Apply topically to the affected area 3 to 4 times daily as needed. Shake well before each use. ## Pediatric Dosing * **Children 6 months and older:** Same as adult dosing (3 to 4 times daily). * **Infants under 6 months:** Not recommended without direct consultation from a pediatrician. ## Dose Adjustments * No systemic dose adjustments are required as the medication is minimally absorbed. Use sparingly on broken or severely abraded skin to prevent irritation. ## Contraindications * Hypersensitivity to any component of the formulation. * Not intended for use on deep puncture wounds, animal bites, or serious burns. ## Adverse Effects * **Dermatologic:** Rare contact dermatitis, skin dryness, or irritation at the application site. * **Systemic:** None anticipated with topical use. ## Key Drug Interactions * None clinically significant. Avoid concurrent application of other topical medications to the same site unless directed, as it may affect absorption or efficacy. ## Monitoring * Monitor for signs of secondary bacterial infection (increased redness, swelling, pus, or fever). * Discontinue use if the condition worsens or if symptoms persist beyond 7 days. ## Clinical Pearls * **Application:** Shake the bottle thoroughly to ensure the active ingredients (which settle) are properly suspended. * **Drying Effect:** The lotion has a drying effect; it is most effective for "weeping" or "oozing" lesions (e.g., poison ivy vesicles). It may exacerbate dry or xerotic skin conditions. * **Patient Education:** Advise patients that the lotion will dry into a pink, chalky powder. It may stain fabrics. * **Safety:** For external use only. Keep away from eyes and mucous membranes. If accidental ingestion occurs, seek medical assistance or contact a Poison Control Center immediately. *** *Disclaimer: This information is for educational purposes only.
