How to treat itching from flea bites? - in detail
Flea bites often produce a localized, intensely itchy rash. Prompt cleaning with mild soap and lukewarm water removes residual saliva and reduces bacterial contamination. After drying, apply a cold compress for 5‑10 minutes to constrict blood vessels and diminish the immediate itching sensation.
Topical options include:
- Over‑the‑counter corticosteroid creams (1 % hydrocortisone) applied thinly to the affected area twice daily for up to three days.
- Calamine lotion or zinc‑oxide paste to create a protective barrier and provide a soothing effect.
- Antipruritic gels containing pramoxine or menthol for temporary relief.
Systemic antihistamines, such as cetirizine 10 mg or diphenhydramine 25 mg, taken orally, counteract histamine release and lessen prolonged itching. Dosage should follow package instructions or physician guidance, especially for children.
Natural adjuncts may complement pharmacologic measures:
- Aloe vera gel, applied directly, offers anti‑inflammatory properties.
- A paste of baking soda and water, left on the bite for 15 minutes, can neutralize skin pH and relieve irritation.
- Oatmeal baths (colloidal oatmeal, 1‑2 cups per gallon of warm water) soothe widespread itching.
Avoid scratching, as mechanical trauma can introduce bacteria, leading to secondary infection. Signs of infection—redness spreading beyond the bite, swelling, pus, or fever—necessitate medical evaluation. Persistent or worsening symptoms after 48 hours warrant professional assessment to exclude allergic reactions or other dermatologic conditions.
