What to use for bed bug bites? - in detail
Bed‑bug bite relief centers on reducing inflammation, preventing infection, and easing itching.
Topical antihistamines such as diphenhydramine cream block histamine release and provide rapid itch control. Corticosteroid ointments—hydrocortisone 1 % or prescription‑strength betamethasone—suppress local immune response, diminishing redness and swelling. Calamine lotion creates a cooling film that soothes irritated skin. Aloe‑vera gel supplies moisture and possesses mild anti‑inflammatory properties, helping to calm the affected area.
Systemic options include oral antihistamines (e.g., cetirizine, loratadine) that address widespread itching and reduce overall histamine activity. Non‑steroidal anti‑inflammatory drugs (ibuprofen or naproxen) alleviate pain and inflammation when bites are numerous or severe.
Cold compresses applied for 10–15 minutes lower temperature, constrict blood vessels, and temporarily numb the skin, limiting the itch cycle. A paste made from baking soda and water, left on for 15 minutes, neutralizes acidity and eases discomfort.
If secondary infection is suspected—signs include increasing warmth, pus, or expanding redness—apply a topical antibiotic (e.g., mupirocin) and consider oral antibiotics after medical evaluation.
Natural agents with documented efficacy include tea‑tree oil (diluted 5 % in carrier oil) for its antimicrobial action, and witch‑hazel extract for astringent, anti‑inflammatory effects.
When multiple bites coalesce, cover the area with a breathable, non‑adhesive dressing to prevent scratching and reduce bacterial entry.
Seek professional care if lesions spread rapidly, fever develops, or allergic reactions such as hives, swelling of the face, or difficulty breathing occur.
