How to treat the consequences of a bedbug bite? - in detail
Bedbug bites commonly cause itching, redness, and swelling that can persist for several days. Immediate care focuses on reducing inflammation and preventing infection.
- Clean the area with mild soap and lukewarm water; pat dry with a clean towel.
- Apply a cold compress for 10–15 minutes, repeat every hour while symptoms are acute.
- Use over‑the‑counter topical corticosteroids (e.g., 1 % hydrocortisone) to lessen erythema and pruritus.
- Antihistamine tablets (cetirizine 10 mg or diphenhydramine 25 mg) taken orally can control widespread itching, especially at night.
- For secondary bacterial infection, a topical antibiotic ointment containing bacitracin or mupirocin should be applied, and a physician‑prescribed oral antibiotic considered if purulence develops.
If the bite remains inflamed beyond 48 hours, or if systemic symptoms such as fever, lymphadenopathy, or spreading rash appear, seek medical evaluation promptly.
Long‑term strategies include:
- Maintaining skin hygiene; shower daily and change bedding regularly.
- Using hypoallergenic laundry detergents to avoid additional irritation.
- Applying a barrier cream (e.g., dimethicone) before sleep to reduce direct contact with residual insects.
Patients with known sensitivities or asthma may require a prescription‑strength steroid or a short course of oral corticosteroids to achieve rapid symptom control.
Documentation of bite location, size, and progression assists healthcare providers in distinguishing bedbug reactions from other arthropod bites or dermatologic conditions.
