How can the itch from bedbug bites be soothed? - briefly

How can the itch from bedbug bites be soothed? - in detail
The itching produced by Cimex lectularius feeding can be reduced through a combination of topical agents, systemic measures, and environmental controls.
Topical treatments
- Hydrocortisone cream (1 %): apply to the bite 2–3 times daily for up to 7 days.
- Calamine lotion: spread a thin layer, let dry, repeat every 4 hours as needed.
- Antihistamine ointments (e.g., diphenhydramine 1 %): use for immediate relief, limited to short‑term use.
- Pramoxine or lidocaine gels: numb the area, apply 3–4 times per day.
- Aloe vera gel: soothe skin and provide mild anti‑inflammatory effect; reapply after washing.
Systemic options
- Oral antihistamines (cetirizine 10 mg, loratadine 10 mg, or diphenhydramine 25 mg): take once daily for moderate to severe pruritus.
- Non‑steroidal anti‑inflammatory drugs (ibuprofen 200 mg): help reduce inflammation accompanying the bite.
- Short course of oral corticosteroids (prednisone 10–20 mg): reserved for extensive eruptions or refractory itching, under physician supervision.
Home remedies with documented efficacy
- Cold compress: apply a clean cloth soaked in cold water for 5–10 minutes, repeat several times a day.
- Oatmeal paste: mix colloidal oatmeal with water to a paste, leave on skin for 15 minutes, then rinse.
- Baking soda slurry: dissolve 1 teaspoon in a cup of water, apply with a cotton ball, rinse after 10 minutes.
- Apple cider vinegar: dilute 1:1 with water, dab onto bite, allow to dry; may provide a mild astringent effect.
Preventive and environmental actions
- Wash all bedding, clothing, and curtains in hot water (> 60 °C) and dry on high heat to kill any remaining insects and eggs.
- Vacuum mattresses, box springs, and surrounding furniture daily; discard vacuum bag immediately.
- Encase mattress and box spring in certified bedbug‑proof covers; replace after infestation is cleared.
- Use a professional pest‑management service for thorough eradication; chemical treatments alone rarely eliminate the problem.
When itching persists beyond 10 days, spreads, or is accompanied by signs of infection (redness, swelling, pus), seek medical evaluation promptly.
