Wash the affected skin with mild soap and water, then apply an over‑the‑counter antihistamine or 1% hydrocortisone cream to relieve itching; avoid scratching. Seek medical care if redness spreads, swelling increases, or signs of infection appear.
How to treat bites from domestic bedbugs? - in detail
When a person is bitten by a domestic bedbug, the skin reaction typically appears as a small, red, itchy papule that may develop into a raised wheal. Immediate care aims to relieve itching, reduce inflammation, and prevent secondary infection.
First, cleanse the affected area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can aggravate the skin. Apply a cold compress for 5–10 minutes to diminish swelling and soothe discomfort.
Pharmacologic relief includes:
- Oral antihistamines (e.g., cetirizine, diphenhydramine) taken according to label dosage to counteract histamine‑mediated itching.
- Topical corticosteroid creams (hydrocortisone 1% or stronger prescription options) applied thinly to each lesion twice daily for up to a week, reducing erythema and edema.
- Calamine lotion or menthol‑based gels for additional cooling effect; reapply every 2–3 hours as needed.
If lesions become painful, ooze, or develop a crust, introduce an over‑the‑counter antibiotic ointment (e.g., bacitracin or mupirocin) to deter bacterial colonization. Keep the area covered with a sterile gauze pad if there is drainage; change dressings daily.
Monitoring signs of infection is essential. Seek medical evaluation if any of the following occur: increasing redness extending beyond the bite, warmth, pus formation, fever, or if the bite does not improve after 48–72 hours of self‑care. A healthcare professional may prescribe oral antibiotics or a stronger steroid preparation.
For individuals with heightened sensitivity, such as those with atopic dermatitis or asthma, consider a short course of systemic antihistamines and consult a physician promptly, as reactions can be more severe.
Avoid scratching, which can introduce pathogens and exacerbate inflammation. Trim fingernails and keep hands clean to minimize accidental injury to the skin.
In summary, effective management of bedbug bites involves thorough cleansing, targeted anti‑itch medication, topical anti‑inflammatory agents, infection control measures, and timely professional assessment when complications arise.
