What should be applied to an itchy bedbug bite? - in detail
Apply a cold compress to the affected area for 10‑15 minutes, repeating every hour for the first few hours. This reduces swelling and numbs the itch.
Use a topical antihistamine cream (e.g., diphenhydramine 1%) or a corticosteroid ointment (hydrocortisone 1%) two to three times daily. These agents block histamine release and suppress inflammatory mediators, providing rapid relief.
If the bite remains intensely pruritic, an oral antihistamine such as cetirizine 10 mg or diphenhydramine 25‑50 mg can be taken once daily. Oral analgesics (acetaminophen or ibuprofen) alleviate pain and discomfort.
Apply a soothing barrier such as calamine lotion or a zinc oxide paste after the initial cooling phase. These formulations create a protective film, lessen moisture loss, and further diminish itching.
Maintain clean skin: wash the bite gently with mild soap and lukewarm water, then pat dry. Avoid scratching to prevent secondary bacterial infection. If signs of infection appear—redness spreading beyond the bite, pus, warmth, or fever—seek medical evaluation promptly.
