How to neutralize a bedbug bite? - in detail
Treat the puncture promptly to limit irritation and prevent infection. Begin by cleansing the area with mild soap and cool water; this removes residual saliva and reduces bacterial load. Pat the skin dry with a clean towel.
Apply a cold compress for 5–10 minutes to constrict blood vessels, which diminishes swelling and numbs the itch. Repeat every hour for the first few hours if discomfort persists.
Topical agents can further control symptoms:
- Hydrocortisone 1 % cream, applied two to three times daily, reduces inflammation.
- Calamine lotion or a 1 % diphenhydramine gel, applied every 4–6 hours, relieves itching.
- A thin layer of petroleum jelly creates a barrier that prevents scratching‑induced skin damage.
Oral antihistamines such as cetirizine 10 mg or diphenhydramine 25 mg, taken once daily, counteract histamine release and lessen pruritus. Use according to package directions; avoid exceeding recommended doses.
If the bite shows signs of infection—redness expanding beyond the lesion, warmth, pus, or fever—seek medical attention. A clinician may prescribe a short course of oral antibiotics (e.g., cephalexin 500 mg three times daily) and a stronger corticosteroid if inflammation is severe.
For persistent swelling, elevate the affected limb and avoid tight clothing that can exacerbate fluid accumulation. Maintain a clean environment; wash bedding and clothing in hot water (≥ 60 °C) and dry on high heat to eradicate any remaining insects and their eggs.
Finally, monitor the site for at least 48 hours. If symptoms do not improve or worsen, professional evaluation is warranted.
