Question
I've used collars and the oil you drop on the skin that get's absorbed into the bloodstream thereby killing the ticks. I have noticed my older lab does not react well the topical treatment. She get's lethargic for a few days and may have some intestinal reaction, diarrhea or very soft BM's.
Due to her age and declining health I am feeling a bit of aversion giving the topical treatment this season.
I am wondering what the active ingredient in the oral medication is and if it's safe for older dogs?
She is 13 years old and still chugging. :-)
Answer
The name of the drug is Bravecto
The active ingredient is Furalaner.
Here is it's safety study.
It enters the bloodstream and has efficacy for up to 8 weeks. Ticks that consume the blood of the host ingest by proxy the insecticide which effects their respiratory system
Here is the FDA application for approval from May 15, 2014.
