What is lotilaner, the active ingredient in Credelio?

Lotilaner is a member of the isoxazoline class of parasiticides. It has acaracidal and insecticidal activity, and acts as an inhibitor of gamma-aminobutyric acid (GABA)–gated chloride channels (GABACls).

Can Credelio be given to dogs with food allergies?

Credelio tablets are made with a beef flavoring containing pork liver and soy but no actual beef. Tablets also contain barley, wheat and lactose. Consult your veterinarian before using in dogs with food allergies to pork, soy, barley, wheat or lactose.

What is the acceptability/ palatability of Credelio

In a field trial, the acceptability of credelio was tested at 10 different locations across the u.s. 94% of dogs accepted Credelio from the hand, in the bowl or with food. The remaining 6% accepted Credelio when placed in the mouth. There were no reports of unsuccessful dosing.

The positive control in the u.s. field trial was Nexgard® (afoxolaner). Acceptability results were very similar, with only 4% reaching the “placed in mouth” stage. Also, Nexgard had no reports of unsuccessful dosing.

What is the shelf life of Credelio?

Please reference the individual packaging of Credelio for the expiration date.

How long does a Credelio tablet remain stable outside the blister pack?

No stability testing has been performed on tablets once they have been removed from the blister pack. We do not recommend taking the tablets out of the blister pack for storage in another container. Credelio tablets should only be taken out of the blister pack at the time of dosing.

Is Credelio gluten-free?
