What should you do if it itches after a bedbug bite? - in detail
Bedbug bites often produce localized itching that can become uncomfortable within minutes. Prompt cleaning of the area reduces the risk of secondary infection and helps relieve irritation. Wash the skin with mild soap and lukewarm water, then pat dry.
Apply a cold compress or an ice pack wrapped in cloth for 10‑15 minutes. The temperature drop constricts blood vessels, decreasing swelling and numbness of the sensation. After cooling, use a thin layer of a topical corticosteroid such as 1 % hydrocortisone or an over‑the‑counter anti‑itch cream containing calamine. These agents inhibit the release of histamine, directly reducing pruritus.
If oral relief is preferred, take an antihistamine tablet (e.g., diphenhydramine 25‑50 mg) every 4‑6 hours, not exceeding the daily maximum. For individuals with chronic allergies or contraindications, a non‑sedating antihistamine like cetirizine 10 mg once daily may be more suitable. Follow package directions and consult a pharmacist if unsure about drug interactions.
Seek professional medical care when any of the following occurs:
- Persistent redness, warmth, or pus indicating infection.
- Rapid spreading of the rash beyond the bite site.
- Severe swelling, difficulty breathing, or hives suggesting an allergic reaction.
- Symptoms lasting more than a week despite self‑treatment.
To minimize future episodes, eradicate the infestation by laundering bedding at 60 °C, vacuuming mattresses, and employing approved insecticidal treatments. Maintaining a clean sleeping environment removes the source of the bites and prevents recurring itchiness.
