How should flea bites on human skin be treated? - briefly
Clean the bite site with mild soap and water, then apply a topical antihistamine or hydrocortisone cream to alleviate itching and inflammation; oral antihistamines can be used for persistent symptoms. Seek medical evaluation if the area worsens, shows infection signs, or fails to improve within a few days.
How should flea bites on human skin be treated? - in detail
Flea bites cause small, red, itchy papules that may develop a central punctum. Prompt care reduces irritation and the risk of secondary infection.
First, cleanse the area with mild soap and lukewarm water. Rinse thoroughly and pat dry; avoid rubbing, which can exacerbate inflammation. Apply a cold compress for 5–10 minutes to lessen swelling and numb the itch.
For symptomatic relief, use one or more of the following:
- Over‑the‑counter antihistamine tablets (e.g., diphenhydramine 25 mg) taken as directed.
- Topical antihistamine creams or gels containing diphenhydramine or doxepin.
- Low‑potency corticosteroid ointments (hydrocortisone 1 %) applied thinly twice daily for up to three days.
- Calamine lotion or a zinc‑oxide paste to dry out weeping lesions.
If the bite becomes intensely painful, shows signs of infection (increased redness, warmth, pus, or fever), or persists beyond a week, seek medical evaluation. Prescription‑strength steroids or oral antibiotics may be required.
Patients with known allergies, asthma, or a history of severe reactions should carry an epinephrine auto‑injector and consider a short course of oral corticosteroids under physician supervision.
Preventive measures include:
- Regularly treating pets with veterinarian‑approved flea control products.
- Washing bedding, clothing, and upholstery in hot water (≥ 60 °C) weekly.
- Vacuuming carpets and upholstery daily, discarding the vacuum bag or cleaning the canister immediately.
- Using indoor insecticide sprays or flea traps in heavily infested environments, following label instructions.
Adhering to these steps provides effective relief and minimizes complications from flea bite reactions.
