What to smear on flea bites? - in detail
Flea bite irritation can be relieved with a range of topical agents that target inflammation, itching, and potential infection.
Over‑the‑counter corticosteroid creams (e.g., hydrocortisone 1 %) reduce swelling and redness when applied thinly to the affected skin two to three times daily for up to a week.
Topical antihistamine preparations such as diphenhydramine gel provide rapid itch suppression; they should be used sparingly to avoid skin dryness.
Calamine lotion forms a protective barrier and dries out weeping lesions; a light coating applied every 4–6 hours is effective.
Antiseptic ointments containing bacitracin or polymyxin‑B prevent secondary bacterial colonization; a thin layer applied after cleaning the area with mild soap and water is recommended.
Natural options include:
- Aloe vera gel – soothing, anti‑inflammatory; apply a fresh slice or pure gel twice daily.
- Witch hazel extract – astringent that reduces edema; dab with a cotton pad three times daily.
- Diluted apple cider vinegar – mild antiseptic; soak a cloth in a 1:1 mixture with water and press onto the bite for 5 minutes, then rinse.
If itching persists despite these measures, an oral antihistamine (e.g., cetirizine 10 mg) may be taken according to package directions.
Seek professional care when any of the following occur: extensive swelling, blisters, pus formation, fever, or a spreading rash, as these signs indicate infection or allergic reaction that requires prescription therapy.
Proper application technique enhances effectiveness: cleanse the skin, pat dry, apply a pea‑size amount of the chosen product, and allow it to absorb before covering with clothing. Avoid scratching, as it exacerbates inflammation and increases infection risk.
