Bravecto 1-Month kills adult fleas and is indicated for the treatment and prevention of flea infestations (Ctenocephalides felis) and the treatment and control of tick infestations [Ixodes scapularis (black-legged tick), Dermacentor variabilis (American dog tick) and Rhipicephalus sanguineus (brown dog tick)] for one month in dogs and puppies 8 weeks of age and older, and weighing 4.4 pounds or greater. Bravecto 1-Month is also indicated for the treatment and control of Amblyomma americanum (lone star tick) infestations for one month in dogs and puppies 6 months of age and older, and weighing 4.4 pounds or greater.

Possible Side Effects

Side effects may include itching, diarrhea, vomiting, decreased appetite, elevated ALT, lethargy, and weight loss. Fluralaner is a member of the isoxazoline class. This class has been associated with neurologic adverse reactions including tremors, ataxia, and seizures. Seizures have been reported in dogs receiving isoxazoline class drugs, even in dogs without a history of seizures. Use with caution in dogs with a history of seizures or neurologic disorders.

Drug & Food Interactions

Due to reduced drug bioavailability in the fasted state, fluralaner should be administered with food.

Do dogs readily eat the Bravecto Chew?

In a US field study where dogs were treated at home, over 93% of dogs ate the chew voluntarily-either by itself or with food.

Can the Bravecto Chew be broken up and crumbled with food?

BRAVECTO Chew should be given with food. If a chew is broken or crumbles, make sure your dog still receives the whole dose.

Do Bravecto Chew tablets contain wheat or gluten?


Does water, grooming, or hair length have an effect on how a Bravecto Chew works?

No. Even immediate bathing, shampooing, or swimming won't affect how well BRAVECTO Chew works because it's not a topical treatment. Coat length and grooming or brushing also have no impact on how well it works.

Is Bravecto Chewy approved for use in Breeding/Pregnant/Lactating dogs?

Yes. BRAVECTO is approved for use in breeding, pregnant, and lactating dogs.

Can Bravecto be used in Collies?

In a well-controlled laboratory study, BRAVECTO was shown to be safe in collies known to be MDR-1 gene deficient. Collies with the defect were administered 3 times the deliverable dose and had no adverse events.

What happens if my dog vomits after taking Bravecto Chew?

If vomiting occurs, check with your vet to decide whether to redose or not; however, if an otherwise healthy dog vomits within 3 hours of receiving BRAVECTO , it is recommended that the dog be redosed. To help ensure that the dog does not vomit again, it is suggested to wait 24 hours until redosing.

If 4 or more hours have passed before the vomiting occurs, it is likely that the medication has been absorbed and the dog is protected. If the vomiting repeats again, DO NOT give a third chew, and call your veterinarian.

If you suspect that a side effect has taken place as a result of giving the dog BRAVECTO, please report it to Merck Technical Services at 1-800-224-5318, and follow any advice that they provide.

    Not great, dog lethargic

    By Missy on Apr 27, 2021

    I am not happy with this flea medication. My vet recommended it. My dog is having some reactions to it, he is lethargic and it seems to be messing with his stomach. If it worked well, I might be able to look past that, but it doesn't. He is still having a lot of fleas, they are not all dieing after being on him. It just isn't giving him much relief at all. Unfortunately I bought 3 months worth. I'm very sad that this isn't helping.
