How can I relieve itching after a bedbug bite? - in detail
Bedbug saliva triggers a localized allergic reaction that often results in intense pruritus. Immediate measures focus on reducing inflammation and preventing secondary infection.
Apply a cold compress for 5–10 minutes, repeating every hour for the first few hours. The temperature drop constricts blood vessels, limiting the release of histamine.
Topical agents that interfere with histamine signaling are effective. Use a 1 % hydrocortisone cream or a prescription-strength steroid (e.g., triamcinolone) applied thinly to the affected area twice daily for up to three days.
Antihistamine tablets such as diphenhydramine (25–50 mg) or cetirizine (10 mg) taken orally can diminish systemic itching. For persistent symptoms, a healthcare professional may prescribe a stronger antihistamine or a short course of oral corticosteroids.
Moisturizing lotions containing calamine, oatmeal, or aloe vera create a protective barrier and soothe the skin. Apply after cleaning the bite with mild soap and water; avoid rubbing, which can exacerbate irritation.
If the bite becomes inflamed, swollen, or shows signs of infection (pus, increasing redness, fever), seek medical attention promptly. Antibiotics may be required to treat bacterial superinfection.
Long‑term strategies include:
- Regularly washing bedding and clothing in hot water (≥ 60 °C) and drying on high heat.
- Vacuuming mattresses, cracks, and furniture weekly; discarding the vacuum bag afterward.
- Using encasements designed to trap insects on mattresses and box springs.
- Applying approved insecticide sprays or hiring professional pest control when infestations are confirmed.
Combining immediate symptom relief with diligent hygiene and environmental control minimizes discomfort and reduces the likelihood of recurrent bites.
