What should be applied for bites from bed bugs? - in detail
Bed‑bug bite treatment begins with thorough cleansing. Wash the affected area with mild soap and lukewarm water to remove irritants and reduce infection risk. Pat the skin dry; avoid rubbing, which can worsen inflammation.
Topical options:
- Hydrocortisone 1 % cream – reduces erythema and itching; apply a thin layer 2–3 times daily for up to 7 days.
- Calamine lotion – provides a cooling effect and mild astringent action; reapply every 4 hours as needed.
- Antihistamine ointments (e.g., diphenhydramine) – alleviate pruritus; limit use to short periods to prevent skin irritation.
- Antibiotic ointment (e.g., bacitracin) – indicated only if secondary bacterial infection is evident; apply after cleaning and cover with a sterile bandage.
Systemic measures:
- Oral antihistamines (cetirizine, loratadine, diphenhydramine) – control widespread itching; follow dosing instructions on the label.
- Analgesics (acetaminophen or ibuprofen) – relieve pain and reduce mild inflammation.
Additional care:
- Cold compress – apply for 10–15 minutes, several times a day, to diminish swelling.
- Moisturizing creams – prevent excessive dryness after steroid or antihistamine use.
- Avoid scratching – reduces risk of secondary infection and prolongs healing.
When to seek professional evaluation:
- Lesions enlarge, become increasingly painful, or develop pus.
- Persistent swelling, fever, or lymph node enlargement appear.
- Symptoms last longer than two weeks despite self‑care.
Preventive advice (though not part of immediate treatment) includes laundering bedding at 60 °C, vacuuming mattresses, and using encasements to limit re‑exposure.
