If a bedbug bites, what should you apply? - in detail
When a bed‑bug bite occurs, the first step is to cleanse the area with mild soap and cool water. This removes potential contaminants and reduces irritation. After cleaning, apply a cold compress for 10–15 minutes to constrict blood vessels and lessen swelling.
For symptomatic relief, use one of the following topical agents:
- Over‑the‑counter hydrocortisone 1 % cream, applied two to three times daily, to suppress localized inflammation.
- Calamine lotion or zinc‑oxide paste, spread thinly, to soothe itching and create a protective barrier.
- Antihistamine cream containing diphenhydramine, applied sparingly, to counter histamine‑mediated itch.
If itching persists, an oral antihistamine such as cetirizine 10 mg or loratadine 10 mg can be taken once daily. For severe reactions, a short course of oral corticosteroids may be prescribed by a physician.
Monitor the bite for signs of infection: increasing redness, warmth, pus, or expanding swelling. Seek medical attention if any of these develop, or if systemic symptoms such as fever, hives, or difficulty breathing appear.
In addition to immediate treatment, keep the bite uncovered to allow airflow, and avoid scratching to prevent secondary skin damage. Regularly launder clothing and bedding in hot water (≥ 60 °C) to eliminate residual insects and reduce the risk of further bites.
