What can be applied to a person's bedbug bites? - briefly
Use a topical antihistamine or low‑strength hydrocortisone cream to soothe itching and swelling, and consider an oral antihistamine or cold compress for additional relief.
What can be applied to a person's bedbug bites? - in detail
Bedbug bites cause localized itching, redness, and swelling. Immediate relief relies on topical agents that calm inflammation and prevent secondary infection. Over‑the‑counter corticosteroid creams (hydrocortisone 1 %) reduce erythema and pruritus when applied two to three times daily for up to a week. Antihistamine ointments containing diphenhydramine provide comparable itch control and can be used on sensitive skin.
When the skin is intact, a cold compress for 5–10 minutes diminishes vascular response and numbs the area, limiting the urge to scratch. After cooling, a thin layer of calamine lotion forms a protective barrier and further soothes irritation. For individuals prone to allergic reactions, oral antihistamines such as cetirizine or loratadine taken once daily address systemic itching.
If lesions show signs of infection—pus, increased warmth, or expanding redness—apply a topical antibiotic like bacitracin or mupirocin. In cases of extensive involvement, a short course of oral antibiotics (e.g., cephalexin) may be warranted under medical supervision.
Moisturizing creams containing aloe vera or oatmeal extract restore skin barrier function and alleviate dryness after the acute phase. Avoid applying harsh chemicals, essential oils, or alcohol‑based products, as they can exacerbate irritation.
Summary of recommended measures:
- Cold compress (5–10 min) → reduces swelling and itching.
- Hydrocortisone 1 % cream → anti‑inflammatory, 2–3 times daily.
- Diphenhydramine ointment or oral antihistamine → itch control.
- Calamine lotion → protective barrier, soothing effect.
- Topical antibiotic (bacitracin, mupirocin) for suspected infection.
- Oral antibiotics (prescribed) for confirmed bacterial spread.
- Aloe‑based or colloidal oatmeal moisturizer → barrier repair after inflammation subsides.
Persistent or severe reactions, such as extensive hives, difficulty breathing, or fever, require immediate medical evaluation. Proper wound care and avoidance of scratching minimize the risk of secondary infection and scarring.
