How to treat a bedbug bite? - in detail
A bedbug bite typically appears as a small, red, itchy papule. Immediate care aims to reduce inflammation, prevent infection, and alleviate discomfort.
First‑aid measures
- Wash the area with mild soap and lukewarm water to remove irritants.
- Pat dry with a clean towel; avoid rubbing.
- Apply a cold compress for 10–15 minutes to constrict blood vessels and lessen swelling.
Topical treatments
- Over‑the‑counter hydrocortisone 1 % cream can be applied twice daily for up to a week to suppress the immune response.
- Antihistamine ointments containing diphenhydramine provide additional itch relief.
- Calamine lotion or zinc oxide paste create a protective barrier and dry out the lesion.
Systemic options
- Oral antihistamines (e.g., cetirizine 10 mg) taken once daily help control widespread itching.
- Non‑steroidal anti‑inflammatory drugs (ibuprofen 200 mg) reduce pain and swelling when needed.
When to seek professional care
- Lesion enlarges, becomes painful, or shows pus, indicating possible secondary infection.
- Symptoms such as fever, lymph node enlargement, or widespread rash develop.
- Persistent itching interferes with sleep or daily activities despite self‑treatment.
Prevention of recurrence
- Vacuum mattresses, furniture, and cracks in walls; discard the vacuum bag afterward.
- Wash bedding and clothing in hot water (≥ 60 °C) and dry on high heat.
- Encase mattresses and box springs in zippered protective covers.
- Inspect sleeping areas regularly for live insects or fecal spots.
Follow‑up
- Re‑evaluate the bite after 48 hours; if inflammation persists, a short course of prescription‑strength corticosteroid cream may be warranted.
- Document any allergic reactions to treatments for future reference.
