K9 Advantix Flea Medicine Side Effectsby Jane Meggitt
A once-monthly topical application of K9 Advantix, manufactured by Bayer Animal Health, keeps your dog free from ticks, mosquitoes, fleas and lice. Its primary ingredients are the pesticides permethrin and imidacloprid. While most dogs tolerate this over-the-counter medication well, some might experience side effects. If your dog develops a bad reaction after receiving K9 Advantix, call your veterinarian.
The most common side effect in dogs after a K9 Advantix application is irritation at the application site -- the skin between the shoulder blades. Some dogs might appear lethargic after receiving the drug, while others start drooling. Vomiting after drug application also occurs in some cases.
