How to relieve a bedbug bite? - in detail
Treat the affected area promptly. Wash the skin with mild soap and lukewarm water to remove irritants and reduce the risk of secondary infection. Pat dry with a clean towel; avoid rubbing, which can aggravate inflammation.
Apply a cold compress or ice pack wrapped in a cloth for 10‑15 minutes. The temperature drop constricts blood vessels, diminishing swelling and numbness of the bite site. Repeat every hour as needed during the first day.
Use over‑the‑counter antihistamine tablets (e.g., cetirizine, loratadine) according to package directions. Histamine blockade limits itching and erythema. For localized relief, spread a thin layer of hydrocortisone cream (1 %) or calamine lotion. Reapply every 4‑6 hours; discontinue after 7 days to prevent skin thinning.
If itching persists, consider a topical anesthetic containing pramoxine or lidocaine. Apply sparingly, allowing the medication to absorb fully before covering the area with a breathable bandage.
Maintain short, clean fingernails; trim if necessary. If scratching occurs, cleanse the wound with antiseptic solution (e.g., povidone‑iodine) and apply a sterile dressing to deter bacterial entry.
Monitor for signs of infection: increasing redness, warmth, pus, or fever. Seek medical attention if any of these develop, or if the bite does not improve after 48 hours despite self‑care measures.
For individuals with severe reactions (e.g., extensive swelling, difficulty breathing), administer an epinephrine auto‑injector if prescribed and call emergency services immediately.
Prevent future bites by inspecting bedding, vacuuming seams, and washing linens at temperatures above 60 °C. Use mattress encasements designed to trap insects and consider professional pest control if infestation is confirmed.
