FDA Warn: Tick And Flea Medicine For Pets May Cause Severe Health Issues


We have heard about a lot of recalls recently as well as warnings on many popular medicines. This is also true of food due to contamination another issues. It seems as if there are some popular pet medicines that are now joining the list.

The FDA has not recalled any of these products but they are issuing a warning to pet owners and veterinarians. There are some potential risks with the use of these medications.

They are speculating that certain tick and flea medications that are used to prevent or treat infestations could result in neurological issues with your dog or cat.

Many pet owners are worried over this warning.

This is what you need to know.

We are saying goodbye to tick season now that the colder weather is coming in but we need to be prepared to give it to our pets when the spring arrives. If you live in a warmer climate, it could be a year-round issue.

The FDA feels that potential adverse reactions may be a problem when pets are treated with the isoxazoline class medications. This includes drugs approved by the FDA, such as Bravecto, Credelio, Nexgard, and Simparica.

“Isoxazoline products have been associated with neurologic adverse reactions, including muscle tremors, ataxia, and seizures in some dogs and cats,” the FDA’s website states.

“Although most dogs and cats haven’t had neurologic adverse reactions, seizures may occur in animals without a prior history.”

What should you do?

The FDA still considers those medications ‘safe and effective’. They are, however, encouraging owners to speak to the veterinarian and discuss which products are best for their pets.

If your pet has an adverse reaction to a drug talk to the veterinarian first. The FDA is also encouraging pet owners to report issues with the drug manufacturer or to submit a report to the FDA directly.
