Clean the bite with mild soap and water, then cover it with an over‑the‑counter antiseptic such as hydrocortisone cream or zinc‑oxide ointment to soothe itching and prevent infection.
What should you apply to a wound after a flea bite? - in detail
A flea bite creates a small puncture that may bleed or become inflamed. Immediate care begins with thorough cleansing. Rinse the area with lukewarm water and a mild soap to remove saliva and contaminants. Pat dry with a clean cloth; do not rub, which could irritate the skin further.
Apply an antiseptic solution such as povidone‑iodine, chlorhexidine, or a diluted hydrogen peroxide solution. Allow the antiseptic to remain on the surface for at least 30 seconds before gently wiping away excess. This step reduces bacterial colonization and lowers infection risk.
For the next 24–48 hours, cover the site with a thin layer of a topical antibiotic ointment—examples include bacitracin, neomycin‑polymyxin B, or mupirocin. The ointment should be spread evenly, then sealed with a sterile, non‑adhesive dressing to keep the medication in place and protect the wound from external debris.
If itching or swelling is pronounced, a low‑potency corticosteroid cream (e.g., hydrocortisone 1 %) can be applied once daily, avoiding the immediate post‑injury period when the skin is still open. For allergic individuals, an oral antihistamine such as diphenhydramine or cetirizine may relieve systemic symptoms.
Monitor the area for signs of infection: increasing redness, warmth, pus, or escalating pain. Should any of these develop, or if the bite is located near the eyes, mouth, or genitals, seek professional medical evaluation promptly.
Maintain hygiene throughout the healing process. Change dressings at least once a day, or sooner if they become wet or contaminated. Avoid scratching, as mechanical trauma can introduce pathogens and delay closure.
In summary, the protocol consists of: cleaning with soap and water, antiseptic application, topical antibiotic coverage, optional anti‑itch treatment, regular dressing changes, and vigilant observation for complications.
