Simparica Tablets

How it Works: 
Simparica contains the active ingredient sarolaner, which inhibits the function of the neurotransmitter gamma aminobutyric acid (GABA) receptor and glutamate receptor, and works at the neuromuscular junction in insects. This results in uncontrolled neuromuscular activity leading to death in insects or acarines. Simparica is administered once a month directly by mouth or can be crumbled and mixed with food. To minimize the likelihood of flea re-infestation, it is important to treat all dogs and cats within a household with an approved flea control product.
