If bitten by bedbugs, how should they be treated? - in detail
When a person experiences bites from Cimex lectularius, immediate care focuses on symptom relief and prevention of secondary infection.
First‑line measures address itching and inflammation:
- Apply a cold compress for 10–15 minutes to reduce swelling.
- Use over‑the‑counter topical corticosteroids (e.g., 1 % hydrocortisone) or calamine lotion to calm pruritus.
- Take oral antihistamines such as cetirizine 10 mg once daily if itching persists.
If lesions become inflamed or show signs of infection, add:
- A topical antibiotic ointment containing bacitracin or mupirocin.
- A short course of oral antibiotics (e.g., cephalexin 500 mg three times daily for 5 days) when purulent discharge or cellulitis is evident.
For severe allergic reactions, including widespread hives or respiratory distress, seek emergency medical attention; administer intramuscular epinephrine as directed by a healthcare professional.
Adjunctive steps to limit further bites and reduce skin trauma:
- Wash all exposed skin with mild soap and lukewarm water; pat dry.
- Trim fingernails to prevent excoriation.
- Launder bedding, clothing, and curtains in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes.
- Vacuum carpets and upholstered furniture thoroughly; discard vacuum bags promptly.
Long‑term control requires eliminating the insect source. Professional pest‑management interventions—heat treatment, steam, or approved insecticides—should be coordinated with the treatment plan to prevent recurrent exposure.
Follow‑up with a clinician if itching continues beyond two weeks, if new lesions appear, or if systemic symptoms develop.
