# Calamine Lotion ## Overview Calamine lotion is a topical skin protectant containing zinc oxide and ferric oxide (which provides the characteristic pink color). It functions as an astringent, anti-pruritic, and mild antiseptic agent to protect and soothe irritated skin. ## Primary Indications * Relief of minor skin irritations and pruritus (itching) associated with poison ivy, poison oak, poison sumac, insect bites, and generalized rashes. ## Adult Dosing * **Topical:** Apply a thin layer to the affected area 3 to 4 times daily as needed. * **Maximum:** No specific maximum dose, but excessive application may lead to excessive drying or caking of the skin. ## Pediatric Dosing * **Infants (>6 months) and Children:** Apply a thin layer to the affected area 3 to 4 times daily as needed. * **Note:** Avoid application near the face, eyes, or mucous membranes to prevent inhalation or contact irritation. ## Dose Adjustments * No hepatic or renal adjustments required as systemic absorption is negligible. ## Contraindications * Hypersensitivity to any component of the formulation. * Do not apply to blistered, raw, draining, or open wounds/lesions unless directed by a provider. ## Adverse Effects * **Dermatologic:** Contact dermatitis, skin dryness, irritation, or stinging. * **Respiratory:** Potential for inhalation of dried powder if applied to areas where it may flake off; ensure the lotion is fully dry before contact with clothing. ## Key Drug Interactions * None observed clinically due to minimal systemic absorption. ## Monitoring * Monitor for signs of secondary bacterial infection (increased redness, warmth, pus, or fever). * Monitor for worsening irritation; discontinue use if condition persists beyond 7 days. ## Clinical Pearls * **Application:** Shake the bottle vigorously before use to ensure proper suspension of the active ingredients. * **Removal:** May be washed off easily with warm water and soap if it causes excessive drying or irritation. * **Drying Agent:** It is highly effective for "weeping" dermatitis (e.g., poison ivy) due to its astringent properties, but may be counterproductive for dry skin conditions. * **Safety:** For external use only. If ingested, seek medical attention or contact a poison control center immediately. *** **Disclaimer:** This information is for educational purposes only.
