Flea Bite Allergy

Flea bite allergy is a common allergic reaction that occurs when a person's immune system overreacts to proteins found in flea saliva. When a flea bites, it injects saliva, which can lead to intense itching, redness, and swelling at the bite site, often resulting in a rash or hives. This allergy is more prevalent in people who have previous sensitivities to insect bites. It's important to manage flea infestations in pets and environments, as well as to treat reactions promptly. Treatments may include antihistamines or corticosteroids to alleviate symptoms.
