FDA Approves BRAVECTO® QUANTUM (fluralaner for extended-release injectable suspension) from Merck Animal Health to Treat and Control Asian Longhorned Tick and Gulf Coast Tick for 12 Months in Dogs
Merck Animal Health, known as MSD Animal Health outside the United States and Canada, a division of Merck & Co., Inc., Rahway, N.J., USA (NYSE: MRK), today announced the U.S. Food and Drug Administration (FDA) approved an expanded label for BRAVECTO® QUANTUM (fluralaner for extended-release injectable suspension) in dogs. The updated indication adds treatment and control of Asian longhorned tick (H. longicornis) and Gulf Coast tick (A. maculatum) for 12 months, when administered as a single, veterinarian‑delivered injection.
BRAVECTO QUANTUM was approved in the U.S. on July 10, 2025, and continues to be indicated to kill adult fleas, for the treatment and prevention of flea infestations, and for the treatment and control of Ixodes scapularis, Dermacentor variabilis, and Rhipicephalus sanguineus infestations for 12 months and A. americanum infestations for 8 months in dogs and puppies 6 months of age and older.
“For more than a decade, BRAVECTO has set the benchmark for extended‑duration flea and tick protection, and today’s label expansion reinforces our leadership in parasiticide innovation,” said Meg Conlon, DVM, executive director, U.S. Companion Animal Veterinary Services, Merck Animal Health. “With BRAVECTO QUANTUM, Merck Animal Health continues to deliver the longest‑lasting protection available in a single dose – now covering an even broader range of clinically important tick species. This advancement reflects our unwavering commitment to help veterinarians protect dogs with the most comprehensive, convenient, and science‑driven solutions on the market.”
Key Information:
- What’s new: BRAVECTO QUANTUM is now approved to provide 12 months of treatment and control for two additional tick species – Asian longhorned tick (H. longicornis) and Gulf Coast tick (A. maculatum) – following a single injection administered by a veterinarian. This approval expands the product’s already robust label, reinforcing BRAVECTO’s position as the longest‑lasting flea and tick protection available for dogs in the United States.
- Complete Parasite Protection Profile: BRAVECTO QUANTUM is indicated to kill adult fleas and for treatment and prevention of flea infestations. BRAVECTO QUANTUM also provides 12 months of protection against Asian longhorned ticks, Gulf Coast ticks, black‑legged ticks, American dog ticks, and brown dog ticks, along with 8 months of protection against lone star ticks following a single veterinarian administered‑injection.
- Why this matters: The extended‑release injectable formulation offers veterinarians and pet owners a simple, once‑yearly approach that supports improved compliance and consistent, uninterrupted protection. This label update helps veterinarians address the evolving parasite landscape, as both Asian longhorned and Gulf Coast ticks continue to expand geographically and present risks to canine health.

The expanded indication underscores Merck Animal Health’s continued leadership in delivering innovative, extended‑duration parasite protection solutions.

About BRAVECTO®
Since its introduction in 2014, BRAVECTO has provided longer-lasting flea and tick protection, with more than 450 million doses distributed in 100 countries over eight years. BRAVECTO is available in a variety of formulations, including products for both dogs and cats.
The flea lifecycle can last as long as 12 weeks, and monthly treatments may leave gaps in protection. Providing pets with continuous flea and tick protection is essential – whether the pet goes outside or not. Contrary to popular belief among pet owners, fleas and ticks are not only active in the spring and summer months and are a year-round risk. Fleas and ticks can easily latch onto dogs and cats and can spread serious diseases. Fleas are the most common external parasite found on pets. BRAVECTO products are available through licensed veterinarians.
