How to reduce swelling after a bedbug bite? - briefly

How to reduce swelling after a bedbug bite? - in detail
Bedbug bites trigger an inflammatory response that often leads to noticeable swelling. Prompt treatment can limit tissue enlargement and alleviate discomfort.
First‑aid measures focus on stabilizing the skin’s reaction. Clean the area with mild soap and lukewarm water to remove irritants and reduce the risk of infection. Pat dry with a clean towel; rubbing can aggravate the lesion.
Cold application constricts blood vessels, slowing fluid accumulation. Apply a wrapped ice pack or a cold, damp cloth for 10‑15 minutes, repeat every hour for the first few hours. Do not place ice directly on the skin to avoid frostbite.
Topical anti‑inflammatory agents provide additional relief. Over‑the‑counter hydrocortisone cream (1 %) applied thinly two to three times daily diminishes histamine‑mediated swelling. For individuals with sensitive skin, a calamine lotion or a 1 % antihistamine gel offers a milder option.
Oral antihistamines, such as diphenhydramine or cetirizine, block systemic histamine release. A standard dose taken within 30 minutes of the bite can curtail swelling and itching. Follow label instructions or consult a pharmacist for dosage guidance.
If swelling persists beyond 48 hours or expands rapidly, medical evaluation is warranted. Prescription‑strength corticosteroids or antibiotics may be required if secondary infection develops.
Lifestyle adjustments help prevent recurrence. Regularly wash bedding in hot water (≥ 60 °C), vacuum mattresses and furniture, and use encasements designed for bedbug control. Reducing exposure minimizes future inflammatory episodes.
