How should you treat a spot after a bedbug bite? - in detail
After a bedbug bite, begin by washing the affected area with mild soap and lukewarm water. Pat dry with a clean towel; avoid rubbing, which can irritate the skin further.
Apply a cold compress for 5–10 minutes to reduce swelling and discomfort. Repeat every hour during the first few hours if needed.
For itch relief, use an over‑the‑counter antihistamine (e.g., diphenhydramine 25 mg) or a topical antihistamine cream. If the reaction is more intense, a low‑potency corticosteroid ointment (e.g., 1 % hydrocortisone) may be applied twice daily for up to three days.
If the bite becomes painful, warm, or shows signs of pus, treat it as a possible secondary infection. Clean the site with an antiseptic solution (e.g., chlorhexidine) and cover with a sterile gauze. Seek medical evaluation for prescription antibiotics if infection is suspected.
Monitor the lesion for several days. Typical reactions subside within 3–7 days. Persistent swelling, spreading redness, or systemic symptoms such as fever warrant professional assessment.
Avoid scratching to prevent skin barrier disruption and bacterial entry. Keep fingernails trimmed and consider wearing gloves when handling contaminated bedding until the skin heals.
