What reduces swelling from a bedbug bite? - in detail
Swelling caused by a bed‑bug bite can be diminished through several pharmacological and non‑pharmacological actions that target inflammation and histamine release.
Applying a cold compress for 10–15 minutes, repeated every hour for the first few hours, constricts blood vessels and limits fluid accumulation. After the initial cooling, a topical steroid such as 1 % hydrocortisone cream reduces erythema and edema by inhibiting inflammatory mediators. Over‑the‑counter antihistamine tablets (e.g., diphenhydramine or cetirizine) block histamine receptors, further decreasing swelling and itching.
Non‑prescription soothing agents also contribute:
- Calamine lotion – creates a cooling film that eases irritation.
- Aloe vera gel – supplies anti‑inflammatory compounds and moisturizes skin.
- Baking soda paste (mix 1 part soda with 3 parts water) – neutralizes pH and calms the reaction.
- Diluted tea‑tree oil (1 % solution) – offers mild antiseptic and anti‑inflammatory effects.
Oral analgesics such as ibuprofen or acetaminophen relieve pain and have modest anti‑inflammatory properties, complementing topical treatment. Maintaining cleanliness by washing the area with mild soap and water prevents secondary infection, which can exacerbate swelling. Avoiding scratching limits mechanical irritation and reduces the risk of bacterial invasion.
If swelling persists beyond 48 hours, spreads rapidly, or is accompanied by fever, seek medical evaluation. Prescription‑strength corticosteroids or antihistamines may be required, and a healthcare professional can assess for allergic reactions or infection that need specific therapy.
