What should be applied to a flea bite on a human? - in detail
Treat a flea bite on a person with a three‑step protocol: cleanse, soothe, and protect.
First, wash the area with mild soap and lukewarm water. Pat dry gently; avoid rubbing, which can exacerbate irritation.
Second, apply a topical anti‑itch agent. Options include:
- 1 % hydrocortisone cream – reduces inflammation and itching.
- Calamine lotion – provides a cooling effect and dries out the lesion.
- 1 % pramoxine or diphenhydramine cream – numbs the skin temporarily.
For severe itching, oral antihistamines such as cetirizine (10 mg) or diphenhydramine (25 mg) can be taken every 12 hours, provided there are no contraindications.
Third, protect the site from secondary infection. Use a thin layer of petroleum jelly or an antibiotic ointment (e.g., bacitracin) if the skin appears broken. Keep the bite covered with a non‑adhesive dressing only if scratching is likely.
Additional measures:
- Apply a cold compress for 5–10 minutes to reduce swelling.
- Avoid scratching; use a clean fingernail or a disposable glove if relief is needed.
- Monitor for signs of infection: increasing redness, pus, fever, or expanding rash. Seek medical attention if these develop.
For individuals with known allergies or a history of severe reactions, a short course of oral corticosteroids (e.g., prednisone 10 mg daily for 3 days) may be prescribed by a clinician. Pregnant or nursing persons should consult a healthcare professional before using any medication.
