What should be used to treat after bedbug bites? - in detail
Bedbug bites are typically painless at first, then develop redness, swelling, and itching. Immediate care focuses on reducing inflammation, preventing infection, and relieving discomfort.
Clean the affected area with mild soap and lukewarm water. Pat dry; avoid rubbing, which can worsen irritation. Apply a cold compress for 10‑15 minutes to limit swelling.
For itching, use over‑the‑counter antihistamine tablets (e.g., diphenhydramine, cetirizine) according to package directions. Topical antihistamine creams (e.g., diphenhydramine lotion) or calamine lotion can be applied directly to the lesion.
If inflammation is pronounced, a low‑potency corticosteroid cream (hydrocortisone 1 %) may be applied two to three times daily for up to one week. Stronger steroids require prescription.
When a bite becomes pustular, crusted, or shows signs of infection—pain, warmth, expanding redness, pus, or fever—use a topical antibiotic ointment (e.g., bacitracin or mupirocin). Persistent infection warrants oral antibiotics prescribed by a clinician.
Additional supportive measures:
- Keep nails trimmed to reduce skin damage from scratching.
- Wear loose‑fitting clothing to minimize friction.
- Use moisturizers after the acute phase to restore skin barrier.
Seek professional evaluation if any of the following occur:
- Severe allergic reaction (difficulty breathing, swelling of lips or tongue).
- Extensive rash covering large body areas.
- Persistent lesions lasting more than two weeks despite self‑care.
Effective management combines hygiene, pharmacologic symptom control, and prompt attention to complications.
