What should I do after a flea bite? - in detail
If a flea lands on your skin and punctures it, immediate care reduces irritation, prevents infection, and limits the chance of an allergic reaction.
First, cleanse the area. Wash with mild soap and lukewarm water for at least 20 seconds. Pat dry with a clean towel; rubbing can worsen inflammation.
Second, apply a topical anti‑itch agent. Options include:
- 1 % hydrocortisone cream – reduces redness and swelling.
- Calamine lotion – soothes itching.
- Antihistamine cream (e.g., diphenhydramine) – blocks histamine release.
If oral relief is preferred, a standard dose of an antihistamine tablet (cetirizine 10 mg or diphenhydramine 25‑50 mg) can be taken, following label instructions.
Third, monitor for signs of infection. Look for increasing warmth, pus, or expanding redness. Should any of these develop, seek medical attention promptly; a physician may prescribe a topical or oral antibiotic.
Fourth, protect the bite from further trauma. Cover with a sterile adhesive bandage if the site is likely to be scratched or rubbed. Change the dressing daily and keep the area dry.
Fifth, assess personal sensitivity. Individuals with known flea‑bite allergies may experience larger welts or systemic symptoms such as fever, headache, or joint pain. In such cases, contact a healthcare provider without delay.
Finally, address the source. Inspect pets, bedding, and living spaces for fleas. Use a veterinarian‑recommended flea‑control product on animals, wash all linens in hot water, and vacuum carpets thoroughly. Consider an environmental treatment (e.g., a flea spray or fogger) if infestation is extensive.
By following these steps—cleaning, medicating, observing, protecting, and eliminating the pest—you minimize discomfort and prevent complications after a flea bite.
