How should I treat bites from bed bugs? - in detail
Treat the skin reactions caused by Cimex lectularius promptly to reduce discomfort and prevent infection. Begin with thorough cleansing: wash the affected area with mild soap and lukewarm water, then pat dry. Apply a cold compress for 5–10 minutes to lessen swelling and itching.
If itching persists, use over‑the‑counter antihistamine tablets (e.g., diphenhydramine 25 mg) or a topical antihistamine cream containing diphenhydramine or cetirizine. For localized inflammation, a low‑potency corticosteroid ointment (hydrocortisone 1 %) may be applied two to three times daily for up to a week.
When lesions become painful, erythematous, or develop pus, treat as a secondary bacterial infection: clean with antiseptic solution, cover with a sterile dressing, and consider a short course of topical antibiotic (e.g., mupirocin) or oral antibiotics prescribed by a clinician.
In cases of extensive reactions, severe swelling, or systemic symptoms such as fever, seek medical evaluation promptly.
Additional care measures:
- Keep fingernails trimmed to avoid self‑inflicted skin damage from scratching.
- Use breathable, loose‑fitting clothing to reduce irritation.
- Wash all bedding, clothing, and soft furnishings in hot water (≥ 60 °C) and dry on high heat to eliminate lingering insects and their feces.
- Apply a moisturizer containing soothing agents (e.g., aloe vera or colloidal oatmeal) after the acute phase to restore skin barrier function.
Monitor the bite sites for changes over several days. If redness expands, pain intensifies, or new lesions appear, re‑evaluate with a healthcare professional.
