Do you own research sometimes apothecary is the best option out there!
Tick tablets (chewables) for dogs contain active ingredients that function as insecticides and acaricides. These medications work systemically by entering your dog's bloodstream. When a tick or flea bites your dog, it ingests the active chemical, which targets its nervous system and kills the parasite.
The FDA has issued official safety alerts warning that chewable tick and flea tablets in the isoxazoline class can cause serious neurological side effects. These include muscle tremors, ataxia (loss of coordination), and seizures, even in dogs without a prior history of neurological issues.
This includes popular prescriptions like Bravecto (fluralaner), NexGard (afoxolaner), Simparica (sarolaner), and Credelio (lotilaner).
