How should the site of a flea bite be treated? - in detail
When a flea bite appears, immediate care reduces irritation and lowers the risk of infection. Begin by cleansing the affected skin with lukewarm water and a mild, fragrance‑free soap. Gently pat the area dry; rubbing can aggravate the inflammatory response.
Apply a topical antihistamine or a 1 % hydrocortisone cream to alleviate itching and swelling. Limit the application to the bite surface and avoid covering with occlusive dressings unless directed by a health professional. If the bite is especially painful, an oral antihistamine (e.g., cetirizine 10 mg) taken every 24 hours can provide additional relief.
Cold compresses, applied for 10–15 minutes several times daily, further diminish edema and soothe discomfort. For persistent redness or minor abrasions, a thin layer of an antibiotic ointment (e.g., bacitracin or mupirocin) helps prevent bacterial colonization.
Monitor the site for signs of complication: increasing warmth, spreading redness, pus formation, or fever. Should any of these symptoms develop, seek medical evaluation promptly, as they may indicate secondary infection or an allergic reaction requiring systemic therapy.
Maintain skin integrity by refraining from scratching. If accidental scratching occurs, cleanse the area again and reapply the anti‑itch preparation. In cases of severe hypersensitivity, a short course of oral corticosteroids prescribed by a clinician may be warranted.
Finally, address the source of infestation. Treat pets with appropriate flea control products, vacuum living spaces thoroughly, and wash bedding at high temperatures to prevent re‑exposure and further bites.
