Clean the bite with mild soap and cool water, apply a cold compress to lessen swelling, then use a topical corticosteroid or antihistamine cream to control itching; if the reaction is widespread, an oral antihistamine can provide additional relief.
What is the best way to treat flea bites? - in detail
Flea bite reactions typically appear as small, red, itchy papules, often in clusters on the lower legs or ankles. Prompt management reduces discomfort, prevents secondary infection, and limits prolonged skin changes.
Initial care focuses on cleansing the area. Wash the affected skin with mild soap and lukewarm water for at least 30 seconds, then pat dry with a clean towel. This removes saliva residues that can exacerbate inflammation.
Topical anti‑itch agents provide rapid relief. Apply:
- 1 % hydrocortisone cream, up to three times daily, for up to seven days.
- Calamine lotion or a 0.5 % diphenhydramine cream as an alternative for patients who cannot tolerate steroids.
If itching persists, oral antihistamines are useful. Recommended options include:
- Cetirizine 10 mg once daily.
- Loratadine 10 mg once daily.
- Diphenhydramine 25–50 mg every 6 hours (avoid in patients with sedation risk).
For extensive or inflamed lesions, a short course of oral corticosteroids may be indicated. Prednisone 0.5 mg/kg per day for three to five days can suppress severe inflammation; taper only if symptoms persist beyond a week.
Secondary bacterial infection must be ruled out. Signs such as increasing warmth, pus, or expanding erythema warrant antimicrobial therapy. First‑line oral antibiotics include:
- Cephalexin 500 mg four times daily for 7–10 days.
- Clindamycin 300 mg three times daily for patients allergic to penicillins.
After the acute phase, moisturize the skin to restore barrier function. Use fragrance‑free emollients or ointments containing ceramides twice daily for at least two weeks.
Preventive measures reduce recurrence. Regularly treat pets with veterinarian‑approved flea control products, vacuum carpets and upholstery, and wash bedding at 60 °C weekly. Environmental sprays containing insect growth regulators (e.g., methoprene) can interrupt the flea life cycle.
