Which ointment should be used to treat bed bug bites? - briefly

Apply a low‑strength corticosteroid cream, such as 1 % hydrocortisone, optionally supplemented with an antihistamine or calamine lotion to relieve itching and inflammation. Avoid petroleum‑based ointments, which can trap heat and exacerbate the reaction.

Which ointment should be used to treat bed bug bites? - in detail

Topical antihistamine creams, such as diphenhydramine, reduce itching by blocking histamine receptors. Apply a thin layer to the affected area up to three times daily; avoid contact with eyes and mucous membranes.

Low‑strength corticosteroid ointments, typically 1 % hydrocortisone, calm inflammation and swelling. Use once or twice a day for no more than a week unless directed by a clinician. Do not apply to broken skin.

Calamine lotion forms a protective film that soothes irritation and dries out minor lesions. Spread evenly and reapply after washing or sweating.

Topical anesthetics containing lidocaine or pramoxine provide temporary numbness. Apply a small amount for 15–20 minutes, then rinse; repeat no more than every four hours.

Antibacterial ointments, such as bacitracin or mupirocin, are warranted only if the bite shows signs of infection—redness spreading, pus, or increased pain. Apply a thin layer after cleaning the area and cover with a sterile dressing.

Natural options include:

  • Aloe vera gel: hydrates and offers mild anti‑inflammatory effects.
  • Tea tree oil (diluted 1 % with carrier oil): possesses antimicrobial properties; test for skin sensitivity first.
  • Witch hazel extract: astringent that may lessen swelling.

Selection criteria:

  1. Severity of reaction – mild itching favors antihistamine or calamine; pronounced swelling benefits corticosteroid.
  2. Presence of infection – antibacterial ointment required.
  3. Patient factors – infants, pregnant women, and individuals with skin disorders should avoid high‑potency steroids and consult a healthcare professional.
  4. Duration of use – limit corticosteroid and anesthetic applications to short periods to prevent skin thinning or systemic absorption.

If symptoms persist beyond 48 hours, worsen, or systemic signs such as fever appear, seek medical evaluation.
