How is a bedbug bite treated? - in detail
Bed‑bug bites cause localized itching, redness, and sometimes swelling. Immediate care focuses on reducing irritation and preventing infection.
First‑line measures include:
- Gently cleanse the area with mild soap and lukewarm water to remove debris and lower bacterial risk.
- Apply a cold compress for 10–15 minutes to lessen swelling and numb itching.
- Use over‑the‑counter antihistamine tablets (e.g., diphenhydramine) or topical antihistamine creams to block histamine release.
- Apply a corticosteroid ointment (hydrocortisone 1 %) to further calm inflammation; limit use to a few days to avoid skin thinning.
If itching persists, consider:
- Oral non‑steroidal anti‑inflammatory drugs (ibuprofen or naproxen) for pain relief and additional anti‑inflammatory effect.
- Prescription‑strength topical steroids or oral antihistamines for severe reactions, administered under medical supervision.
Signs that warrant professional evaluation:
- Expanding redness, warmth, or pus indicating secondary bacterial infection.
- Systemic symptoms such as fever, widespread rash, or difficulty breathing.
- Persistent or worsening lesions beyond two weeks.
Medical treatment may involve:
- Antibiotics (e.g., cephalexin or clindamycin) for confirmed bacterial involvement.
- Short courses of oral corticosteroids for intense inflammation unresponsive to topical agents.
- Referral to an allergist if the patient exhibits hypersensitivity reactions.
After the acute phase, maintain skin integrity by avoiding scratching, which can introduce bacteria. Moisturizing creams can assist in barrier repair. Document the bite pattern and timing to aid healthcare providers in diagnosing possible allergic or infectious complications.
