How to treat allergy from a bed bug bite? - in detail

Bed‑bug bites can trigger localized allergic reactions characterized by redness, swelling, itching, and occasional hives. Prompt care reduces discomfort and prevents secondary infection.

Initial measures focus on hygiene and symptom relief. Gently wash the area with mild soap and lukewarm water to remove irritants. Apply a cold compress for 10–15 minutes, repeating every hour as needed, to diminish swelling and pruritus.

Pharmacologic control includes oral and topical agents.

  • Oral antihistamines (e.g., cetirizine, loratadine) counteract histamine release, alleviating itch and erythema.
  • Short‑course oral corticosteroids (e.g., prednisone 5–10 mg daily for 3–5 days) are reserved for severe or widespread reactions.
  • Topical corticosteroids (e.g., hydrocortisone 1 % cream) applied 2–3 times daily target local inflammation.
  • Calamine lotion or menthol‑based creams provide additional soothing effects.

Medical evaluation becomes necessary if symptoms progress to extensive swelling, difficulty breathing, rapid pulse, or signs of infection such as pus formation, fever, or increasing pain. Emergency care is indicated for anaphylactic manifestations, including throat tightness, wheezing, or hypotension.

Long‑term management emphasizes avoidance. Inspect sleeping areas for mattress seams, box‑spring crevices, and furniture joints; encase mattresses and pillows in zippered covers; wash bedding in hot water (≥ 60 °C) and dry on high heat. Reduce clutter, vacuum regularly, and consider professional pest‑control interventions when infestations are confirmed.
