What should be applied to a bed bug bite site? - in detail
Apply a gentle cleanser to the affected area immediately after noticing the bite. Soap and lukewarm water remove potential contaminants and reduce the risk of secondary infection. Pat the skin dry; avoid rubbing, which can aggravate irritation.
For symptom relief, use one or more of the following topical agents:
- Cold compress – 10‑15 minutes, repeated every hour, to constrict blood vessels and lessen swelling.
- Antihistamine cream (e.g., diphenhydramine 1 %) – reduces histamine‑driven itching; apply thinly, no more than three times daily.
- Low‑potency corticosteroid ointment (hydrocortisone 1 %) – mitigates inflammation and pruritus; limit use to five days to prevent skin thinning.
- Calamine lotion – forms a protective film, soothing the skin and drying exudate.
- Aloe‑vera gel – provides cooling effect and promotes wound healing; apply after the skin is clean and dry.
If oral relief is needed, consider an over‑the‑counter antihistamine tablet (e.g., cetirizine 10 mg) taken once daily. Ensure adequate hydration and avoid scratching, which can introduce bacteria.
Monitor the bite for signs of infection: increasing redness, warmth, pus, or fever. Seek professional medical attention if any of these develop, or if the reaction spreads beyond the local area.
