Severe itch from a flea bite, what should I do? - in detail
Intense itching after a flea bite requires prompt care to reduce discomfort and prevent infection. Begin by cleaning the area with mild soap and lukewarm water; this removes saliva and reduces bacterial load. Pat the skin dry rather than rubbing, which can aggravate irritation.
Apply a cold compress or an ice pack wrapped in a cloth for 10‑15 minutes. The cooling effect constricts blood vessels, temporarily dulling the sensation and decreasing swelling. After the compress, use an over‑the‑counter topical antihistamine or a corticosteroid cream (e.g., hydrocortisone 1 %). Apply a thin layer to the bite no more than three times daily.
If oral relief is needed, take an antihistamine tablet such as diphenhydramine or loratadine according to package directions. Avoid scratching; repeated trauma can break the skin, allowing bacteria to enter and cause cellulitis.
Monitor the site for signs of infection:
- Redness spreading beyond the bite
- Increased warmth or swelling
- Pus or fluid discharge
- Fever or chills
Should any of these symptoms appear, seek medical attention promptly. A healthcare provider may prescribe a stronger steroid cream or oral antibiotics.
Prevent future occurrences by treating pets with appropriate flea control products, washing bedding in hot water, vacuuming carpets regularly, and using indoor insecticides or traps as needed. Maintaining a clean environment reduces the likelihood of re‑infestation and subsequent bites.
