BRAVECTO® PLUS (fluralaner and moxidectin topical solution) for Cats Receives Approval from US Food and Drug Administration

“BRAVECTO PLUS addresses five of the top parasite concerns among veterinarians and cat owners, including ticks, fleas, heartworms, roundworms and hookworms,” said Christine Royal, DVM, director, Professional Services at Merck Animal Health. “These parasites are not just a nuisance, but also pose animal and human health risks. Ticks and fleas can transmit disease; and heartworm disease, transmitted by mosquitoes, is a serious, progressive disease that often goes undiagnosed in cats. We are pleased to offer cat owners the latest innovation from the BRAVECTO family.”

“With BRAVECTO PLUS for cats, we have expanded our portfolio in the fight against parasites by creating an extended duration formulation, ensuring pets receive the broad-spectrum parasite coverage,” Dr. Royal said.

BRAVECTO PLUS contains fluralaner (280 mg/mL), an ectoparasiticide which has systemic activity against ticks and fleas, and moxidectin (14 mg/mL), an endectocide which has systemic activity against a range of external and internal parasites.

BRAVECTO PLUS treats fleas and ticks fast, killing 100 percent of fleas and more than 99.7% of ticks in the first 12 hours after the product is applied.¹ This protection works quickly and lasts. Additionally, roundworm is the most common feline intestinal parasite, affecting up to 75% of cats, and is also effectively treated with BRAVECTO PLUS.² The quality of extended-duration treatment with BRAVECTO PLUS helps to improve compliance among pet owners, which may lead to healthier cats.^3,4

BRAVECTO PLUS is part of the Merck Animal Health pet health portfolio, which includes Sure Petcare, a range of digitally connected products.

About BRAVECTO^® (fluralaner)

Since its introduction in 2014, BRAVECTO has provided longer-lasting flea and tick protection, with more than 100 million doses distributed in 85 countries over five 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. One treatment with BRAVECTO lasts 12 weeks, protects almost three times longer than monthly treatments and is proven to kill fleas on dogs and cats and to eliminate them from the home.⁵

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, including tapeworms and Lyme disease. They also can bite and pose health risks to human family members whether at home or outdoors. Fleas are the most common external parasite found on pets.

BRAVECTO products are only available through licensed veterinarians.
