About Bravecto
Bravecto is a veterinary parasiticide brand developed and marketed by Merck Animal Health, known as MSD Animal Health in many countries outside the United States and Canada. The brand is best known for its long-lasting flea and tick control products for dogs and cats, utilising the active ingredient fluralaner, an insecticide and acaricide belonging to the isoxazoline class.[1]
Introduced in 2014, Bravecto became one of the first widely available oral flea and tick treatments designed to provide extended protection from a single dose. Its original chewable tablet formulation for dogs was notable for offering up to 12 weeks of flea and tick protection, distinguishing it from many traditional monthly treatments.[1]

History
Prior to the introduction of Bravecto, most flea and tick preventives for companion animals were designed around monthly administration schedules. Merck Animal Health developed Bravecto to provide longer-lasting protection and improve treatment consistency among pet owners.
The first Bravecto product approved in major markets was a fluralaner chewable tablet for dogs. In 2014, it received approval from the U.S. Food and Drug Administration for dogs, becoming the first chewable flea and tick product approved in the United States that provided up to 12 weeks of protection from a single dose.[1]
The Bravecto product line subsequently expanded to include:
- Topical treatments for dogs and cats
- Products with different dosing intervals
- Monthly formulations for younger dogs
- Injectable extended-release formulations, including yearly protection options in some markets[1]
Active Ingredient: Fluralaner
The key component of Bravecto is fluralaner, a synthetic compound in the isoxazoline family.
Fluralaner works by interfering with the nervous system of fleas and ticks. It blocks specific ligand-gated chloride channels in parasites, causing paralysis and death, while being designed for veterinary use in mammals.[2]
Unlike traditional topical repellents that mainly remain on the skin surface, Bravecto products are generally systemic treatments, meaning the active ingredient circulates through the animal’s body. Fleas and ticks are killed after feeding on the treated animal.[1]
Product Range
Bravecto Chews for Dogs
The original Bravecto product is a flavoured chew containing fluralaner.
Key features include:
- Treats and controls flea infestations
- Controls several tick species
- Provides up to 12 weeks of protection depending on parasite species and region
- Available in weight-based dosing strengths[1]
Bravecto Topical Solution
Bravecto Topical is a spot-on formulation applied to the animal’s skin. It is available for both dogs and cats. The topical version provides extended flea and tick protection and was developed as an alternative for animals that may not be suitable for oral medications.[1]
Bravecto Plus for Cats
Bravecto Plus combines fluralaner with additional parasite protection ingredients in certain markets. It is designed to provide broader protection against external parasites and selected internal parasites in cats.[1]
Bravecto Quantum / Injectable Products
The Bravecto line has expanded into injectable extended-release formulations. In 2025, the FDA approved BRAVECTO QUANTUM for dogs in the United States, offering a once-yearly flea and tick protection option.[1]
How Bravecto Works
- A pet receives Bravecto according to its weight and the product instructions.
- Fluralaner enters the animal’s system.
- Fleas and ticks are exposed to the medication when they bite and feed.
- The parasites are rapidly killed, helping reduce infestation levels.
Bravecto does not function primarily as a physical barrier that prevents all parasite attachment; instead, it kills parasites after exposure.[2]
Target Parasites
Bravecto products are designed to control various flea and tick species, including:
Fleas
- Ctenocephalides felis
Ticks
Depending on location and formulation, target species include:
- Black-legged ticks
- American dog ticks
- Brown dog ticks
- Lone star ticks
- Asian longhorned ticks in approved regions[2][1]
Veterinary Uses
Bravecto is commonly used for:
- Flea infestation treatment
- Tick infestation control
- Flea allergy dermatitis management as part of flea elimination strategies
- Routine parasite prevention programmes recommended by veterinarians[1]
Safety and Side Effects
Like other veterinary medicines, Bravecto can cause side effects in some animals.
Reported adverse effects may include:
- Vomiting
- Diarrhoea
- Reduced appetite
- Lethargy
- Increased thirst
- Flatulence
Veterinary guidance is recommended, particularly for animals with a history of seizures or neurological disorders, as stated in product safety information for certain formulations.[1]
Market Position
Bravecto has become one of the leading extended-duration flea and tick prevention brands worldwide due to three major factors:
Longer Protection Duration
Many Bravecto products provide protection periods longer than traditional monthly treatments, reducing the number of doses owners need to remember.[2]
Multiple Administration Options
The brand offers different delivery methods, including oral chews, topical solutions, and injectable formulations. This allows veterinarians to select products based on animal needs and owner preferences.[1]
Veterinary Distribution
Many Bravecto products are prescription or veterinarian-directed products, emphasising veterinary involvement in parasite management decisions.[1]
Brand Identity
The name “Bravecto” is associated with long-lasting parasite protection, veterinary science and innovation, convenience for pet owners, and companion animal health management. Its branding focuses on reducing the burden of flea and tick prevention by providing extended-duration solutions rather than frequent monthly treatments.
Summary
Bravecto is a global veterinary parasite-control brand created by Merck Animal Health. Since its launch in 2014, it has become widely recognised for using fluralaner, an isoxazoline compound, to provide extended flea and tick protection for dogs and cats. Through chews, topical applications, and newer injectable technologies, Bravecto represents one of the major advancements in modern companion-animal parasite prevention.[1]
