Bravecto Chews for Dogs is a prescription flea and tick chew from Merck Animal Health that provides up to 12 weeks of protection from a single dose — nearly three times longer than monthly products. Its active ingredient, fluralaner, kills fleas and ticks in dogs 6 months of age and older weighing at least 4.4 lb.

How to use
Give one chew orally every 12 weeks, year-round, with food or a small treat to ensure proper absorption. Remove the chew from the foil blister only when ready to give it, and make sure the entire chew is consumed. Dogs over 123 lb receive an appropriate combination of chews, as directed by your veterinarian.
Safety information
The most commonly reported adverse reactions are vomiting, lethargy, diarrhea, anorexia, and pruritus. Fluralaner is a member of the isoxazoline class, which has been associated with neurologic adverse reactions including tremors, ataxia, and seizures — even in dogs without a prior history of seizures. Use with caution in dogs with a history of seizures or neurologic disorders. Bravecto Chews has not been shown to be effective for 12 weeks in puppies less than 6 months of age, and is not effective against lone star ticks beyond 8 weeks of dosing.
Frequently asked questions
How long does Bravecto last?
One chew protects for up to 12 weeks against fleas and black-legged, American dog, and brown dog ticks, and for 8 weeks against lone star ticks. That is about four doses per year for year-round coverage.
What is the difference between Bravecto and NexGard?
Both are prescription isoxazoline chews. NexGard (afoxolaner) is given monthly and can start at 8 weeks of age; Bravecto (fluralaner) lasts up to 12 weeks per chew for dogs 6 months and older.
Is Bravecto safe for dogs with a history of seizures?
Use with caution. Seizures have been reported in dogs receiving isoxazoline-class drugs, even in dogs without a history of seizures; talk to your veterinarian about your dog's neurologic history first.
Is a prescription required?
Yes. Bravecto Chews is a prescription medication and requires authorization from a veterinarian who has examined your dog within the past 12 months.
