How to treat flea bites in people? - in detail
Flea bites cause small, red, itchy papules that may develop a central punctum. Immediate care focuses on reducing inflammation, preventing infection, and relieving discomfort.
First‑line measures
- Gently wash the area with mild soap and lukewarm water to remove any residual flea material.
- Pat dry; avoid rubbing, which can aggravate the skin.
- Apply a cold compress for 5‑10 minutes to diminish swelling and itching.
Topical interventions
- Over‑the‑counter hydrocortisone 1 % cream, applied two to three times daily, limits the local immune response.
- Calamine lotion or a 1 % diphenhydramine cream provides additional antipruritic effect.
- Antiseptic ointments containing bacitracin or mupirocin are appropriate if the skin shows signs of abrasion or early infection.
Systemic options
- Oral antihistamines such as cetirizine 10 mg or diphenhydramine 25‑50 mg every 4‑6 hours control widespread itching.
- Non‑steroidal anti‑inflammatory drugs (ibuprofen 200‑400 mg every 6‑8 hours) alleviate pain and reduce inflammation.
- Prescription oral corticosteroids are reserved for severe, extensive reactions; a short tapering course is preferable to avoid systemic side effects.
When to seek professional care
- Rapid enlargement of the lesion, pus formation, or increasing redness extending beyond the bite site.
- Fever, chills, or malaise suggesting systemic involvement.
- Persistent itching or swelling lasting more than 7 days despite self‑treatment.
Prevention of recurrence
- Treat pets with flea‑control products approved by veterinary authorities.
- Wash bedding, clothing, and upholstery in hot water (≥ 60 °C) and vacuum carpets regularly.
- Use environmental insecticides or flea traps in infested indoor areas, following label instructions.
By combining proper cleansing, targeted topical agents, appropriate systemic medication, and vigilant monitoring for complications, most flea bite reactions resolve within a week without lasting effects.
