What should you apply to treat bedbug or flea bites? - in detail
Bedbug and flea bites produce localized itching, redness, and swelling. Prompt relief depends on reducing inflammation, preventing secondary infection, and soothing the skin.
Apply a cold compress or ice pack wrapped in a cloth for 10–15 minutes several times a day. The cold stimulus constricts blood vessels, diminishing swelling and the urge to scratch.
Topical treatments that provide anti‑inflammatory and antipruritic effects include:
- Hydrocortisone cream (1 %): reduces redness and itch for up to 24 hours; apply a thin layer 2–3 times daily.
- Calamine lotion: creates a cooling film that eases irritation; reapply after each wash.
- Antihistamine ointments (e.g., diphenhydramine 1 %): block histamine release; use sparingly to avoid skin sensitization.
- Over‑the‑counter analgesic gels containing menthol or camphor: produce a counter‑irritant sensation that distracts from itch.
If skin breaks or becomes infected, apply a topical antibiotic such as bacitracin or mupirocin to the affected area after cleaning with mild soap and water.
Oral antihistamines (cetirizine, loratadine, or diphenhydramine) taken according to package directions can control widespread itching, especially when multiple bites are present.
Avoid scratching; use protective bandages or gloves if necessary. Seek professional care if lesions enlarge, develop pus, or are accompanied by fever, as systemic infection may require prescription antibiotics or corticosteroids.
