What should be applied to treat bedbug bites on a person? - in detail
Treat bed‑bug bites with a step‑by‑step approach that reduces itching, inflammation, and risk of secondary infection.
Begin by washing the affected area with mild soap and lukewarm water. Pat dry; do not rub, which can aggravate the skin.
Apply a cold compress for 10–15 minutes to diminish swelling and provide immediate relief.
Topical options include:
- Low‑potency corticosteroid creams (hydrocortisone 1 %) applied 2–3 times daily for up to a week.
- Over‑the‑counter antihistamine ointments (e.g., diphenhydramine) for localized itching.
- Calamine lotion or zinc‑oxide paste to create a protective barrier and soothe irritation.
If itching is widespread or severe, oral antihistamines such as cetirizine 10 mg or diphenhydramine 25‑50 mg may be taken every 12 hours, respecting dosage limits. Non‑steroidal anti‑inflammatory drugs (ibuprofen 200‑400 mg) can relieve pain and reduce inflammation.
Monitor the bites for signs of infection: increasing redness, warmth, pus, or fever. Should any of these appear, seek medical attention promptly; a physician may prescribe topical antibiotics (e.g., mupirocin) or oral antibiotics if bacterial involvement is suspected.
In cases of hypersensitivity or persistent lesions, a dermatologist might consider a medium‑strength corticosteroid (triamcinolone 0.1 %) for a short course.
Avoid scratching, as mechanical trauma can introduce bacteria and prolong healing. Keep nails trimmed and consider wearing cotton gloves at night if compulsive scratching occurs.
Maintain skin hydration with fragrance‑free moisturizers to support barrier recovery.
Overall, the regimen combines cleansing, anti‑itch agents, anti‑inflammatory medication, and vigilant observation to manage bed‑bug bite reactions effectively.
