Fleas are an annoyance for any pet and pet owner, so it’s essential to locate a flea treatment that works immediately. There are numerous flea treatments and preventives are available for pets, making it challenging to select the proper treatment for you and your pet.

If you’re looking for a quick and effective way to get rid of those pesky fleas, Capstar is the finest option for you and your furry friend. It is available in a variety of formulations to treat all dogs and cats. Capstar comes in the form of an easy-to-administer pill and begins eliminating fleas within just 30 minutes after treatment, providing quick relief. Capstar can also be used in conjunction with other preventive treatments to give all-around flea protection.

How Does Capstar Work?

During dosing, Capstar flea control pills are entirely absorbed in the intestinal tract. Following oral administration, the levels of its key ingredient in the animal’s blood will reach critical levels after around 40 minutes in cats and 80 minutes in dogs.

When a flea feeds on your pet’s blood, they consume enough of the nitenpyram to kill them. It does not affect immature fleas, larvae, or eggs since they do not eat blood meals.

Nitenpyram is the active ingredient of Capstar. It is a neonicotinoid, which affects the flea’s nervous system by binding to acetylcholine receptors. Acetylcholine is a crucial neurotransmitter, and a receptor barrier interferes with nerve signal transmission of the flea.
