How to treat itching after flea bites? - in detail
Flea bites trigger localized redness, swelling, and intense pruritus. The skin reaction results from flea saliva proteins that provoke an allergic response. Prompt care reduces discomfort and prevents secondary infection.
Cleaning the affected area with mild soap and lukewarm water removes irritants and reduces bacterial colonization. Applying a cold compress for 10‑15 minutes limits inflammation and numbs the itch temporarily.
Topical agents provide targeted relief:
- 1 % hydrocortisone cream applied twice daily for up to seven days.
- Calamine lotion spread thinly to dry skin, re‑applied every four hours as needed.
- Aloe vera gel or witch‑hazel pads for soothing and anti‑inflammatory effects.
Systemic antihistamines counteract histamine release:
- Diphenhydramine 25 mg orally every 4–6 hours, limited to short‑term use.
- Cetirizine 10 mg once daily for persistent itching, with minimal sedation.
Home‑based remedies complement pharmaceutical options:
- Oatmeal bath: dissolve colloidal oatmeal (1–2 cups) in lukewarm water, soak 15–20 minutes.
- Baking soda paste: mix equal parts baking soda and water, apply to lesions for 10 minutes, then rinse.
- Honey‑infused gauze: thin layer of raw honey over bite, covered with sterile dressing for antimicrobial action.
Medical evaluation becomes necessary if any of the following occur:
- Rapid expansion of redness, warmth, or pus formation.
- Severe swelling extending beyond the bite site.
- Systemic symptoms such as fever, hives, or difficulty breathing.
Long‑term prevention focuses on eliminating the flea source. Regular veterinary flea control, frequent washing of pet bedding, and vacuuming of carpets interrupt the life cycle and reduce future bites.
