Dangers of Oral Flea and Tick Medications By Mike Kohn DVM

Oral flea and tick medications belong in the Isoxazoline class of insecticides. These products include Bravecto (Fluralaner) tablets for dogs, Nexgard (Afoxalaner) tablets for dogs, Simparica (Sarolaner) tablet for dogs , and Credelio (Lotilaner) tablets for dogs and cats. The FDA (Food and Drug Administration) has alerted pet owers and veterinarians of the potential for neurologic adverse events in dogs and cats when given these drugs orally. 

So what is the problem with these oral products? I’ll quote Dr.W.Jean Dodds (over 40 Years of Veterinary research and founder of Hemopet the first non-profit National Animal Blood Bank). She has directly done research on the adverse consequences of these insecticide products for dog.

“Nexgard one of the Isoxazoline class of parasiticides. Please do NOT use any of them again. There are now two Isoxazoline – related class action lawsuits in North America – one in Quebec and the other in New Jersey. The FDA finally required warnings on the labels and product inserts. As these drugs work by displacing fat from tissues, you can help detox and remove them faster by adding oils like coconut oil (to your pet’s diet)’.

Many of these oral flea and tick products have been associated with seizures death and unprovoked aggression.
