When are topical corticosteroids recommended for bed bug bites?

Bed bug bites can cause itchy red bumps, and scratching may break the skin. A topical corticosteroid can reduce the inflammatory reaction and itch, but it does not kill bed bugs, remove them from a room, or treat an infection. A clinician may avoid steroid use on broken, infected-looking, or uncertain lesions until the skin has been examined. The treatment choice also depends on the area involved and the person's age.

Use the medicine exactly as directed on intact affected skin, and wash hands after application. Keep nails short, use a cool compress for comfort, and avoid scratching. Wash bedding and clothing as appropriate and arrange professional pest control guidance for the living space. Do not apply steroid cream inside the eyes, mouth, or on a wound unless specifically told to do so.

Seek care if bites become hot, increasingly painful, swollen, pus-filled, or heavily crusted, or if redness spreads. Get urgent help for facial or throat swelling, breathing trouble, dizziness, or widespread blistering. If new lesions continue appearing despite addressing the environment, a clinician can check the diagnosis and consider another cause of the rash.

Ask whether the lesions look like bed bug bites, which areas may receive the cream, and how to recognise infection. Check what steps are needed to stop further exposure in your home.
