How should one treat after a flea bite? - in detail
Flea bites appear as small, red punctate lesions, often grouped in clusters. They may itch intensely and, in some individuals, cause a mild rash or swelling.
Immediate care
- Clean the area with mild soap and running water to remove any debris.
- Pat dry with a clean towel; avoid rubbing, which can aggravate the skin.
- Apply a cold compress for 5–10 minutes to reduce swelling and relieve itching.
Topical treatment
- Use an over‑the‑counter antihistamine cream (e.g., diphenhydramine) or a corticosteroid ointment (e.g., hydrocortisone 1 %) to control inflammation.
- If itching persists, a topical calamine lotion can provide additional soothing effect.
- Do not apply heat or irritants such as alcohol, which may worsen the reaction.
Systemic relief
- Oral antihistamines (e.g., cetirizine 10 mg) taken once daily can lessen itch and prevent secondary scratching.
- Non‑steroidal anti‑inflammatory drugs (e.g., ibuprofen 200 mg) may be used for pain or pronounced swelling, following label directions.
Preventing infection
- Keep the bite uncovered; cover only with a sterile, non‑adhesive dressing if the site is likely to be scratched.
- Change dressings daily and monitor for signs of infection: increasing redness, warmth, pus, or fever.
- If any of these symptoms develop, seek medical attention promptly.
Home remedies
- A paste of baking soda and water applied for 10 minutes, then rinsed, can neutralize skin irritation.
- Aloe vera gel offers moisture and mild anti‑inflammatory properties.
- Oatmeal baths (colloidal oatmeal added to lukewarm water) soothe widespread itching.
Environmental control
- Treat pets with veterinary‑approved flea preventatives to eliminate the source.
- Vacuum carpets, upholstery, and pet bedding daily; discard vacuum bags or clean canisters immediately.
- Wash bedding and clothing in hot water (≥ 60 °C) and dry on high heat to kill any remaining insects or eggs.
When professional care is required
- Persistent or severe reactions lasting more than 48 hours.
- Evidence of an allergic response such as hives, difficulty breathing, or swelling of the face and throat.
- Confirmed secondary infection or worsening skin condition.
Following these steps provides comprehensive management of flea‑induced skin lesions and reduces the risk of complications.
