Credelio FAQ

Is Credelio safe for my youngest dog?

When used as directed, Credelio is suitable for use in puppies and dogs from 8 weeks of age, weighing 4.4 lbs or more.

Which parasites does Credelio protect my dog against?

This oral treatment is effective against fleas, lone star ticks, American dog ticks, black-legged ticks, brown dog ticks and longhorned ticks. It is also indicated for the prevention of Lyme disease as a direct result of killing black-legged vector ticks.

How does Credelio for dogs work?

Credelio contains Lotilaner. After administration, this active ingredient is absorbed into the dog's bloodstream. The formula interrupts the transmission of nerve signals in parasites, causing uncontrolled neuromuscular activity and death of the parasites, including fleas and various tick species.

How often should I treat my dog with this chew?

It is recommended that you administer one dose of Credelio every month, preferably on the same date each month.

How long does this chew remain stable outside the blister pack?

For maximum efficacy, you should only take the tablets out of the blister pack at the time of dosing. Do not take the tablets out of the blister pack for storage in another container.

Is Credelio gluten-free chew?

Yes, Credelio is considered a gluten-free chewable treatment.

Why do I still see fleas on my dog after treating this pet with Credelio?

Credelio is known to kill adult fleas quickly and effectively. For comprehensive flea control, you should treat all the animals in the household. Also, your dog is continuously exposed to fleas from the environment. New fleas may continue to jump on your pet and infest them. Credelio kills these fleas shortly after they are attached to the dog.

What should I do if I miss a dose?

When you miss a dose, give one dose immediately with food and continue with the monthly dosing schedule.

Is it necessary to administer this chew with food?

This oral flea and tick treatment must be administered with food or given within 30 minutes of feeding. This ensures your dog achieves peak blood levels and exposure, which is essential for initial and ongoing efficacy.

How quickly does this chew start killing fleas?

According to laboratory studies referenced in the label, the chew began to kill fleas four hours after administration or infestation and killed more than 95% of them within eight hours.

Can I use this chewable flea and tick treatment on a breeding dog?

The safety of Credelio in breeding dogs has not been established.

Is it safe to split these tablets?

Credelio Chews are not scored for splitting and, therefore, splitting these chews is not recommended.
