How can flea bites on a person be treated at home? - briefly
Apply a cold compress to reduce swelling, then treat the area with an over‑the‑counter antihistamine or hydrocortisone cream while keeping it clean and covered with a breathable bandage. If itching continues, take an oral antihistamine and ensure the environment is free of fleas.
How can flea bites on a person be treated at home? - in detail
Flea bites cause red, itchy papules that may develop a small blister or a hive‑like swelling. Immediate care focuses on reducing inflammation, preventing infection, and relieving discomfort.
First, cleanse the affected area with mild soap and lukewarm water. Pat dry with a clean towel; rubbing can worsen irritation. Apply a cool compress for 10–15 minutes, repeating several times a day, to diminish swelling and soothe itching.
Topical remedies that can be used without prescription include:
- 1 % hydrocortisone cream applied thinly to each bite, limited to three days to avoid skin thinning.
- Calamine lotion or a 0.5 % pramoxine gel for additional itch relief.
- A thin layer of petroleum jelly or a 5 % zinc oxide ointment to protect the skin and maintain moisture.
If the reaction is more intense, an oral antihistamine such as diphenhydramine (25 mg for adults) or cetirizine (10 mg) can be taken every 24 hours, following package directions. Non‑steroidal anti‑inflammatory drugs (ibuprofen 200–400 mg) may also reduce pain and swelling.
For secondary infection prevention, keep nails trimmed short and avoid scratching. If a bite becomes warm, painful, or exudes pus, clean it again with antiseptic solution (e.g., chlorhexidine) and apply a thin strip of sterile gauze with a topical antibiotic ointment such as bacitracin.
Additional supportive measures:
- Wear loose, breathable clothing to reduce friction.
- Use an oatmeal bath (colloidal oatmeal added to lukewarm water) for 15–20 minutes daily; it calms widespread itching.
- Maintain a clean living environment: wash bedding, clothing, and pet bedding in hot water (≥60 °C) to eliminate remaining fleas and their eggs, reducing the likelihood of new bites.
Monitor the lesions for signs of allergic reaction (rapid swelling, difficulty breathing) or persistent worsening. Seek professional medical attention if such symptoms appear.
