Reactions to Advantage Flea Treatment

There are many spot-on flea treatments available today. One of the most familiar brands is Advantage, marketed by Bayer. It's been on the market for over ten years. But is it safe? What are the common reactions to it?

  1. Active Ingredient

    • The active ingredient in Advantage is imidacloprid. It works by attacking the flea's nervous system, causing paralysis and death.

    Warnings

    • Because it's a topical, it's considered safe; however, you can see adverse effects from an overdose, or when used in animals that are hypersensitive to insecticides.

    Side Effects

    • Common side effects are a greasy residue or skin irritation at the application site. If an animal licks it while it's wet, you could see drooling. More rarely vomiting, diarrhea, sluggishness, weakness, increased drinking, coughing, or even behavior changes can occur in hypersensitive animals.

    First Aid

    • If you think your pet is having a reaction to Advantage, immediately wash and rinse him thoroughly and call your veterinarian.

    Limitations

    • Advantage is labeled for puppies over 7 weeks old, and kittens over 8 weeks of age. If your pet is pregnant, nursing, has an existing health condition, or is on chronic medications, check with your veterinarian before using.

    Bottom Line

    • Advantage is considered a safe and effective spot flea treatment when used according to label directions, and on the advice of your veterinarian.
