How can I remove swellings from bedbug bites? - in detail
Swelling after a bedbug bite results from the body’s histamine response. Immediate measures focus on limiting the inflammatory reaction, while later steps aim to promote healing and prevent infection.
Apply a cold compress for 10–15 minutes several times during the first hour. The cold temperature constricts blood vessels and reduces fluid accumulation. Follow with an over‑the‑counter antihistamine such as diphenhydramine or cetirizine; the drug blocks histamine receptors and diminishes both itch and edema. If oral antihistamines are unsuitable, a topical antihistamine cream can be spread thinly over the bite.
Use a corticosteroid cream (hydrocortisone 1 %) no more than three times daily for up to seven days. The steroid suppresses local immune activity, accelerating the reduction of puffiness. For severe or persistent swelling, a short course of oral corticosteroids prescribed by a physician may be necessary.
Maintain skin hygiene to avoid secondary infection. Wash the area gently with mild soap and lukewarm water, then pat dry. If the bite becomes painful, warm, or shows pus, seek medical evaluation; antibiotics may be required.
Additional supportive actions:
- Elevate the affected limb or body part to improve venous return.
- Keep fingernails trimmed to reduce damage from scratching.
- Apply a thin layer of aloe vera gel or a moisturizing ointment to preserve skin barrier function.
- Avoid heat sources such as hot showers or heating pads, which can exacerbate swelling.
If swelling does not improve within 48 hours, or if systemic symptoms (fever, widespread rash, difficulty breathing) appear, obtain professional medical care promptly.
