Credelio For Dogs: A New Flea And Tick Solution For Dogs

Credelio For Dogs: A New Flea And Tick Solution For Dogs

Credelio For Dogs: Credelio is a once-a-month flea and tick prevention for dogs. It contains lotilaner, which is in the isoxazoline class of parasiticides. Lotilaner works by interfering with the nervous system of fleas and ticks, paralyzing and ultimately killing them.

Within 4 hours of administration, lotilaner starts working to eliminate existing fleas on your dog. It then continues to prevent future infestations for a full month. The same goes for ticks – Credelio kills common ticks like deer ticks, American dog ticks, and brown dog ticks and prevents re-infestation.

Credelio is available as chewable, flavored tablets for dogs over 8 weeks of age and 4.4 pounds. The dosage is one tablet per month based on your dog’s weight. It’s best given with food for maximum effectiveness.

How Credelio Works to Kill Fleas and Ticks

Credelio For Dogs: A New Flea And Tick Solution For Dogs

Credelio works by interfering with the nervous system of fleas and ticks to cause paralysis and death. Within 4 to 6 hours, Credelio will eliminate an infestation of fleas on your dog and continue working for up to 5 weeks with a single dose. For ticks, Credelio starts killing within 8 to 12 hours and keeps working up to one month.

How it Targets Fleas

Credelio contains the active ingredient lotilaner, which inhibits certain neurotransmitters in fleas that are important for mobility and survival. Specifically, lotilaner blocks the gamma-aminobutyric acid (GABA)-regulated chloride channels in the flea’s nervous system. This results in uncontrolled activity of nerves and muscles, leading to flea paralysis and death. Because Credelio works systemically, it kills fleas after they bite the dog and start feeding.

How it Eliminates Ticks

For ticks, Credelio works in a similar fashion by blocking the GABA-regulated chloride channels. This causes increased neuronal stimulation in ticks leading to uncontrolled nerve activity, paralysis and death. Credelio starts working rapidly to kill ticks already on the dog, as well as new ticks that attach within one month after administration.

With a fast-acting, long-lasting, and complete formula, Credelio provides dog owners an effective and convenient oral flea and tick control solution. By stopping infestations at their source, Credelio helps create a comfortable environment for dogs and the people who love them.
