What should be done if a flea bite itches? - in detail
A flea bite that produces itching requires prompt care to relieve discomfort and prevent infection.
First, cleanse the affected area. Wash with mild soap and cool water for at least 30 seconds, then pat dry with a clean towel. This removes saliva and reduces the risk of bacterial colonization.
Second, apply a topical anti‑itch agent. Options include:
- 1 % hydrocortisone cream, applied thinly three times daily for up to seven days.
- Calamine lotion or a 0.5 % pramoxine gel for immediate soothing.
- Over‑the‑counter antihistamine cream (e.g., diphenhydramine) for localized relief.
Third, consider systemic antihistamines if the reaction spreads or is intense. Oral cetirizine 10 mg or diphenhydramine 25 mg, taken once daily, can diminish histamine‑mediated itching.
Fourth, avoid scratching. Scratching can breach the skin barrier, leading to secondary bacterial infection. If the urge is strong, cover the bite with a breathable bandage or use a cold compress for 10‑15 minutes, repeating every hour as needed.
Fifth, monitor for signs of infection: increasing redness, swelling, warmth, pus, or fever. Should any of these develop, seek medical evaluation promptly; a clinician may prescribe topical or oral antibiotics.
Finally, implement preventive measures to reduce future bites:
- Maintain regular pet grooming and flea control (e.g., topical insecticides, collars, or oral medications).
- Vacuum carpets and upholstery weekly, discarding the vacuum bag or cleaning filter.
- Wash bedding and pet linens in hot water (≥ 60 °C) weekly.
These steps collectively alleviate itching, protect skin integrity, and minimize the likelihood of recurrent flea exposure.
