How should I treat a flea bite on a human? - in detail
Flea bites appear as small, red punctate lesions, often clustered in groups of two or three. The central point may be slightly raised and can itch intensely. Prompt care reduces inflammation, prevents infection, and alleviates discomfort.
First, cleanse the area with mild soap and lukewarm water. Rinse thoroughly and pat dry with a clean towel. Applying an antiseptic solution—such as povidone‑iodine or chlorhexidine—creates a barrier against bacterial invasion.
For symptomatic relief, follow these steps:
- Cold compress – place a clean, cold cloth on the bite for 5–10 minutes to diminish swelling and itching.
- Topical corticosteroid – use a 1 % hydrocortisone cream or a prescription‑strength steroid for persistent inflammation; apply a thin layer no more than three times daily.
- Antihistamine – oral cetirizine 10 mg or diphenhydramine 25 mg can control pruritus; limit use to the recommended duration.
- Analgesic – acetaminophen or ibuprofen (200–400 mg) eases pain and reduces edema.
If the lesion shows signs of infection—pus, increasing redness, warmth, or fever—seek medical evaluation. A clinician may prescribe oral antibiotics (e.g., cephalexin) and may recommend a stronger steroid preparation.
Avoid scratching, which can introduce bacteria and exacerbate tissue damage. Keep nails trimmed and consider using a protective bandage if the bite is in an area prone to irritation.
Preventive measures include:
- Regularly vacuum carpets, upholstery, and pet bedding.
- Wash pet bedding in hot water weekly.
- Apply veterinarian‑approved flea control products to animals.
- Use insect‑repellent sprays or powders on indoor surfaces where fleas are suspected.
By following these protocols, most flea bites resolve within a few days without complications. Persistent or worsening symptoms warrant professional assessment.
