What should be used after a bedbug bite? - in detail
After a bedbug bite, begin with gentle cleansing. Wash the area with mild soap and lukewarm water to remove irritants and reduce the risk of infection. Pat the skin dry; avoid rubbing.
Apply a cold compress or ice pack wrapped in a cloth for 10–15 minutes. The temperature reduction lessens swelling and numbs the itch temporarily.
Topical anti‑itch agents are essential. Use a 1 % hydrocortisone cream or a calamine lotion applied thinly to the affected spot three to four times daily. For those preferring non‑steroidal options, a 2 % diphenhydramine cream or a preparation containing pramoxine provides comparable relief.
Oral antihistamines complement topical treatment. A standard dose of diphenhydramine (25–50 mg) or cetirizine (10 mg) taken once daily can diminish systemic itching and reduce redness. Follow package instructions or physician guidance for dosage and frequency.
If the bite is inflamed or shows early signs of infection—purulent discharge, increasing warmth, or expanding redness—apply a thin layer of over‑the‑counter antibiotic ointment such as bacitracin or polymyxin‑B‑neomycin. Cover with a sterile gauze pad if needed, and monitor for improvement.
Natural remedies may serve as adjuncts. Aloe vera gel, applied directly, soothes and hydrates the skin. A paste of baking soda and water, left on for 15 minutes before rinsing, can neutralize acidity and lessen irritation. Essential oils, notably tea tree or lavender, should be diluted (one drop in a teaspoon of carrier oil) before topical use to avoid dermatitis.
Avoid scratching. Keep fingernails trimmed and consider wearing cotton gloves at night if compulsive itching occurs. Maintain a clean environment; wash bedding and clothing in hot water (≥ 60 °C) and dry on high heat to eliminate remaining insects and prevent further bites.
Seek medical attention if symptoms persist beyond 48 hours, if swelling spreads rapidly, or if systemic reactions such as difficulty breathing, hives, or fever develop. Professional evaluation may be required for prescription‑strength corticosteroids or antibiotics.
