How to relieve itch after a bedbug bite? - in detail
Bedbug bites often produce localized itching, redness, and swelling. Immediate measures focus on reducing histamine release and preventing secondary infection.
Apply a cold compress for 5–10 minutes several times a day. The temperature drop constricts blood vessels, limiting inflammatory mediator flow and decreasing sensation intensity.
Topical antihistamines, such as diphenhydramine cream, block histamine receptors on skin cells. Apply a thin layer to the affected area after cleaning with mild soap and water; repeat every 4–6 hours as needed.
Corticosteroid ointments (e.g., 1 % hydrocortisone) suppress local immune response. Use sparingly, not exceeding a week, to avoid skin thinning.
Oral antihistamines (loratadine, cetirizine) provide systemic relief for extensive itching. Follow dosage instructions on the package; avoid concomitant sedating agents if alertness is required.
Moisturizing agents containing oatmeal, aloe vera, or calamine soothe irritated skin and create a protective barrier. Apply after each cleansing session to maintain hydration and reduce scratching urge.
If itching persists beyond 48 hours, or if signs of infection (increased warmth, pus, spreading redness) appear, seek medical evaluation. Prescription‑strength steroids or antibiotics may be required.
Avoid scratching to prevent skin damage and bacterial entry. Keep fingernails trimmed, wear gloves when necessary, and consider using a topical barrier such as petroleum jelly to reduce friction.
Eliminate the source of bites by inspecting bedding, furniture, and clothing for live insects or shed exoskeletons. Wash all fabrics at ≥ 60 °C, vacuum carpets thoroughly, and employ encasements for mattresses and pillows. Professional pest control may be necessary for severe infestations.
