What helps with itching after a bedbug bite? - in detail
Bedbug bites often cause localized redness, swelling, and a persistent itch that can last several days. Prompt cleaning of the affected area reduces the risk of secondary infection and prepares the skin for topical treatments. Gently wash with mild soap and lukewarm water, then pat dry.
Cold therapy offers immediate relief. Apply a clean, cold compress or an ice pack wrapped in cloth for 10‑15 minutes, repeating as needed. The temperature drop constricts blood vessels, diminishing inflammation and the urge to scratch.
Pharmacological options include:
- Oral antihistamines such as diphenhydramine or cetirizine; typical adult doses are 25 mg and 10 mg respectively, taken every 4‑6 hours or once daily. These agents block histamine release, reducing itch intensity.
- Topical corticosteroids (1 % hydrocortisone cream) applied thinly to the bite area two to three times daily. The anti‑inflammatory action calms erythema and pruritus.
- Local anesthetic gels containing lidocaine (2 %–5 %) provide short‑term numbness when applied for 5‑10 minutes before washing off.
Non‑prescription soothing agents are useful adjuncts:
- Calamine lotion forms a protective barrier and dries out the lesion, easing irritation.
- A paste of baking soda and water (≈1 : 1 ratio) left on the bite for 15 minutes then rinsed off neutralizes skin acidity, lowering itch signals.
- Colloidal oatmeal baths (½ cup oatmeal per gallon of water) soak the skin for 15‑20 minutes, delivering anti‑inflammatory polysaccharides.
- Aloe vera gel, applied directly, supplies moisture and mild anti‑inflammatory compounds.
Avoidance of scratching is critical; keep fingernails trimmed short and consider wearing soft gloves at night. If itching persists beyond a week or lesions become infected (increased pain, pus, fever), seek medical evaluation for possible prescription-strength therapy or antibiotics.
Long‑term management focuses on eliminating the source of bites. Wash all bedding, clothing, and curtains in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets and upholstered furniture, then discard the vacuum bag. Professional pest‑control treatment may be required for severe infestations.
