How can a bedbug bite be treated? - in detail
Bedbug bites typically appear as small, red welts surrounded by a slightly raised halo. Itching, swelling, and occasional pain develop within hours and may persist for several days. Secondary infection can occur if the skin is broken by scratching.
Immediate self‑care measures include:
- Gentle cleansing of the affected area with mild soap and lukewarm water.
- Application of a cool compress for 10–15 minutes to reduce swelling and discomfort.
- Use of over‑the‑counter topical antihistamines or corticosteroid creams to alleviate itching.
Pharmacological options:
- Oral antihistamines (e.g., cetirizine, diphenhydramine) taken according to package directions can control systemic itching.
- Topical corticosteroids (e.g., hydrocortisone 1 %) applied two to three times daily reduce inflammation.
- Analgesic ointments containing lidocaine or pramoxine provide temporary numbness.
Medical evaluation is warranted when:
- Lesions exhibit increasing redness, warmth, or pus, indicating bacterial infection.
- Swelling spreads rapidly or involves the face, lips, or tongue, suggesting an allergic reaction.
- Symptoms persist beyond a week despite self‑treatment.
Preventive actions to limit re‑exposure:
- Wash bedding, clothing, and curtains in hot water (≥ 60 °C) and dry on high heat.
- Vacuum mattresses, furniture, and cracks in walls; discard vacuum bags immediately.
- Encase mattresses and box springs in zippered, bedbug‑proof covers.
- Inspect secondhand furniture before introduction into living spaces.
Effective management combines prompt skin care, appropriate medication, and environmental control to minimize discomfort and prevent further bites.
