Couldn't find a good description of mechanism of action on Wikipedia. I also have nerve cells that need to communicate and damaging them just to spite a tick seems counterproductive.
I'm surprised that similar sounding drugs are making their way to humans. I'm not a chemist and I'm not sure how similar lotilaner and flurolaner are, but damn if I'm not suspicious.
That's awful and way too young. I hope the class action has a good outcome.
And yes, it is technically a mammal neurotoxin too, although our bodies are better at compartmentalizing and managing the risk. Similarly, you don't drop dead if exposed to caffeine or nicotine, even though they are insect neurotoxins produced by plants to kill bugs.
But it cracks me up that we are flipping out about herbicides such as glyphosate or 2,5-D - both of which are plant growth regulators that have no real mechanism to cause obvious harm in animals - but we're a lot more flippant with actual animal neurotoxins such as permethrin.
