What is Credelio for Dogs?

Credelio for Dogs is a prescription chewable tablet that kills adult fleas and ticks. It contains lotilaner, which belongs to a class of medications called isoxazolines. Lotilaner works by interfering with the normal function of fleas’ and ticks’ nervous systems, ultimately leading to their paralysis and death.

It’s important to note that Credelio is a prescription medication, which means you’ll need to consult your veterinarian before obtaining it for your dog. During this visit, your veterinarian can assess your dog’s individual needs and health status to determine if Credelio is the most suitable flea and tick prevention option.

How Does Credelio Work?

Once administered, lotilaner, the active ingredient in Credelio, is absorbed into your dog’s bloodstream. Lotilaner disrupts the normal function of nerve impulses in fleas and ticks. This disruption affects their ability to move and feed, ultimately leading to their death.

Here’s a closer look at Credelio’s mechanism of action:

  • Fast-Acting: Credelio starts killing fleas within 4 hours of administration and begins killing ticks within 24 hours.
  • Long-lasting Protection: A single dose of Credelio provides continuous protection against fleas and ticks for a full month.

This fast-acting and long-lasting protection makes Credelio a convenient and effective solution for preventing flea and tick infestations on your dog.
