Soresto Collar Danger

[Crowe]

Found this article on issues with Soresto collars: https://whdh.com/news/popular-flea-collar-for-pets-linked-to-nearly-1700-deaths-documents-show/

I had heard rumors of issues in the past but never saw anything to back it up until now.

I use Soresto collars and toxicity has never been an issue. However, you can choose another collar for your pet. Here is a helpful article on this topic ***Link Removed***https://catspurfection.com/top-7-best-flea-collar-cats.html

We have an English Springer Spaniel that started scratching and licking almost obsessively recently. We wondered if the Seresto collar may have caused this?
The use of the collar and the licking of her front legs and paws seemed to coincide.
We took the collar off about a week ago after reading some of the complaints and she is much better. The obsessive linking is much better. We will see if it continues to get better as the chemicals work out of her system.

My two cents.

That's a good theory. It is a well known fact that flea and tick collars that are made for dogs will kill cats.

I have been wondering if these reported adverse reactions are due to genetics of the impacted animal.

In reading up on how these slow release collars and spot-on treatments work I came across statements about how on cats certain active ingredients (or formulations) are not as effective as on dogs because the adsorption through the skin of the active ingredients is faster in cats than dogs lowering the amount of the drug on the skin of the cat to kill flees and ticks.

I then browsed the literature for transdermal drug delivery in humans (i.e. nicotine patch) and came across studies on the impact of certain genetic mutations that alter how fast drugs are absorbed from the patch to the blood stream.

These literature findings suggest to me that it is possible there are canine mutations that alter how fast drugs on the skin (via spot-on or slow release collars) are absorbed through the skin and if this process is fast enough the serum levels could become high enough to become toxic.

Raw data is very similar to...

It really is worth the post. People need to be aware and at the earliest sign of a problem contact their vet. On the flip side, these may be isolated incidents may or may not be related to the collar.

My take on this is the number of deaths related to the collar mean nothing without the number of collars sold also included in the details. Soresto is the number one selling flea collar. What is the percentage of animals that have a reaction? Example: 1,700 deaths/17,000,000 collars sold = .01% of collars sold caused deaths.
My point is every mammal has the ability to be allergic to any chemical be it man made or natural. Personally, I could die if stung by a honey bee.

Agree. Raw data is useless but I thought it was worth a post.

Another issue is the phrase "associated with." I'm not aware that it has been shown that the deaths were caused by the collar.

This situation does need to be investigated and causality established.

These collars first came out in 2012 (I think) and most of adverse reports on the veterinary boards I checked list dermatologic issues. There has not been any discussion about serious toxicity issues. Some have speculated that "counterfeit" collars purchased online could be the issue.

Regardless, this is something that needs to be investigated. But, as some have said they have used this collar for years with no side effects.

Maggie the Wonder Beagle has been wearing the Seresto flea collars for nearly 6-years with zero ill effects. everything...literally everything we do in life carries risk. I will monitor this story but in the interim we will continue to use Seresto collars.

If there is a danger to dogs from this collar, there is a danger to humans also.
