Hi Christine-
I think I’ve used all of the flea & tick meds that people complain about and say have killed their pet with literally no issue. You have to take a lot of the complaints on the internet with a grain of salt. I used Frontline Plus once for my cat…no issues. I know plenty of others who have used Fipronil based products for a long time with no issue.
As long as you aren’t having issues with it and it continues to work, then I think you’re safe. If you are looking to switch, I’d suggest asking your vet for a recommendation for a different product. I personally use Bravecto for both my dogs and have had great success with it. It is a 3 month oral product.
