Credelio Quattro

Credelio Quattro (lotilaner, moxidectin, praziquantel, and pyrantel chewable tablets) is the broadest* parasite protection of its kind covering 6 types of parasites in one chewable tablet. It protects against ticks, fleas, heartworm disease and the three intestinal worms that can be passed to humans tapeworms, roundworms and hookworms. Credelio Quattro is effective and works fast where it counts. It kills >99% of fleas within 8 hours of administration and remains effective for an entire month. What's more, Credelio Quattro contains lotilaner that kills ticks** twice as fast as sarolaner in Simparica Trio and afoxolaner in NexGard. This FDA-approved medication delivers all the protection your dog needs in a convenient monthly chewable. It uses four powerful ingredients to provide the broadest* protection that lasts all month long by covering 6 types of parasites. Credelio Quattro comes in a tasty, easy-to-give chewable that's also meat allergy friendly***. In fact, Credelio Quattro was accepted by nearly 9 out of 10 dogs.
