What should be applied to a bedbug bite to prevent itching? - in detail
Apply a cold compress immediately after noticing the bite. The chill reduces blood flow and numbs the area, limiting the itch response.
Topical antihistamine creams, such as diphenhydramine, block histamine receptors on skin cells and provide rapid relief. Use a thin layer three to four times daily, avoiding broken skin.
Low‑strength corticosteroid ointments (1 % hydrocortisone) suppress local inflammation. Apply twice daily for up to one week; discontinue if irritation develops.
Calamine lotion creates a soothing barrier and dries excess fluid. Apply with a cotton swab, let dry, and reapply as needed.
Aloe‑verga gel offers cooling and anti‑inflammatory properties. Use a generous amount after cleaning the bite; repeat every few hours.
For persistent itching, oral antihistamines (e.g., cetirizine 10 mg) can be taken once daily. They reduce systemic histamine levels and lessen overall discomfort.
Home remedies with proven efficacy include:
- Baking soda paste: mix one part baking soda with three parts water, let set for 10 minutes, then rinse.
- Oatmeal slurry: blend colloidal oatmeal in warm water, apply with a soft cloth, leave for 15 minutes.
- Tea tree oil: dilute 1 % in a carrier oil and dab onto the bite; monitor for allergic reaction.
General care steps:
- Wash the area with mild soap and lukewarm water to remove irritants.
- Pat dry; do not rub, which can worsen inflammation.
- Keep fingernails trimmed to reduce skin damage from scratching.
- Apply one of the above topical agents promptly; reapply according to product instructions.
- If swelling, blistering, or severe pain persists beyond 48 hours, seek medical evaluation.
