Apply a cold pack or ice wrapped in a cloth for several minutes to numb the area, then treat with an over‑the‑counter antihistamine or 1% hydrocortisone cream to suppress the itch. Keep the bite clean and avoid scratching to prevent secondary infection.
Как остановить зуд от укуса блохи? - in detail
Flea bites trigger a localized skin reaction that can become intensely itchy. The irritation results from saliva proteins injected during feeding, which provoke an immune response. Immediate relief and prevention of further discomfort rely on a combination of topical, systemic, and environmental measures.
Apply a cold compress to the affected area for 5–10 minutes. The temperature drop constricts blood vessels, reducing swelling and the release of histamine that fuels itching. After the compress, clean the skin with mild soap and water to remove any residual flea saliva and reduce the risk of infection.
Topical options that directly counteract the itch include:
- Hydrocortisone cream (1 %) – apply thinly 2–3 times daily for up to 7 days; it suppresses inflammation.
- Calamine lotion – spreads a soothing film that eases burning sensations.
- Pramoxine or lidocaine gel – provides localized anesthetic effect for rapid numbness.
- Antihistamine cream containing diphenhydramine – blocks histamine receptors on the skin.
If the reaction spreads or is severe, oral antihistamines such as cetirizine, loratadine, or diphenhydramine can be taken according to package dosing. For persistent or secondary bacterial infection, a short course of oral antibiotics prescribed by a physician may be required.
Additional strategies to limit scratching and promote healing:
- Keep nails trimmed to minimize skin damage.
- Wear loose clothing over the bite to reduce friction.
- Use a mild moisturizer after the topical medication dries; hydrated skin is less prone to irritation.
- Avoid heat sources (hot showers, heating pads) that can intensify itching.
Environmental control is essential to stop new bites. Treat pets with veterinarian‑recommended flea preventatives (topical spot‑on, oral tablets, or collars). Vacuum carpets, upholstery, and pet bedding daily, then discard the vacuum bag or clean the canister. Wash all linens in hot water (≥ 60 °C) and apply an insecticide spray approved for indoor use to floorings and cracks where fleas may hide. Repeat the treatment cycle every 2–3 weeks to break the flea life cycle.
Monitoring the bite’s progress is straightforward. The lesion should diminish in size and color within 3–5 days. Persistent redness, swelling, or pus indicates infection and warrants medical evaluation. By combining immediate symptomatic relief with systematic flea eradication, the itching caused by flea bites can be effectively halted.
