What should be applied to bed bug bite sites? - in detail
Bed bug bites typically appear as red, itchy papules that may develop a central punctum. Immediate care focuses on reducing inflammation, alleviating pruritus, and preventing secondary infection.
Topical agents
- Hydrocortisone 1 % cream applied two to three times daily for up to one week to diminish erythema and swelling.
- Calamine lotion or zinc‑oxide paste applied every 4–6 hours to soothe itching.
- Antihistamine ointments containing diphenhydramine applied as needed for acute pruritus.
- Antiseptic solutions such as 0.5 % povidone‑iodine or chlorhexidine applied once after cleaning the area to reduce bacterial colonisation.
Oral medications
- Non‑steroidal anti‑inflammatory drugs (e.g., ibuprofen 200–400 mg every 6–8 hours) for systemic discomfort.
- Oral antihistamines (e.g., cetirizine 10 mg daily) to control widespread itching.
- Antibiotics only when clinical signs of infection arise (e.g., cellulitis, purulent discharge).
Supportive measures
- Cool compresses applied for 10–15 minutes, repeated several times per day, to lessen swelling.
- Gentle cleansing with mild soap and lukewarm water before topical application.
- Avoidance of scratching to prevent skin barrier disruption.
Indications for professional evaluation
- Rapid expansion of redness, warmth, or pain.
- Fever, chills, or malaise.
- Persistent lesions beyond two weeks despite self‑care.
Effective management combines anti‑inflammatory, antipruritic, and antiseptic strategies while monitoring for signs of infection. Prompt escalation to medical care is warranted when symptoms progress.
