What should be applied to the skin after bed bug bites? - in detail
After a bed‑bug bite, the first step is to cleanse the area with mild soap and lukewarm water. This removes irritants and reduces the risk of secondary infection.
Apply a topical antihistamine or a hydrocortisone cream (1 % concentration) to alleviate itching and inflammation. Antihistamine gels containing diphenhydramine work quickly, while low‑strength corticosteroids provide longer‑lasting relief.
If the bite is swollen, a cold compress for 10–15 minutes, repeated every hour, decreases edema.
For persistent itching, a calamine lotion or a zinc‑oxide paste creates a protective barrier and soothes the skin.
When signs of infection appear—redness spreading beyond the bite, warmth, pus, or fever—apply an over‑the‑counter antibiotic ointment (e.g., bacitracin or mupirocin) and seek medical evaluation.
Oral antihistamines (e.g., cetirizine or loratadine) can be taken if multiple bites cause widespread discomfort.
Avoid scratching; it can break the skin and introduce bacteria. Keep fingernails trimmed and consider wearing gloves at night until itching subsides.
Summary of recommended topical agents:
- Mild soap + lukewarm water for cleaning
- 1 % hydrocortisone cream or diphenhydramine gel for itch control
- Calamine lotion or zinc‑oxide paste for barrier protection
- Antibiotic ointment if infection is suspected
These measures address irritation, inflammation, and infection risk, providing comprehensive skin care after bed‑bug exposure.
