U.S. FDA Approves New Indication for Merck Animal Health’s Bravecto® (fluralaner topical solution) for Cats and Bravecto® Plus (fluralaner and moxidectin topical solution) for Cats

Single dose topical treatments are the first and only U.S. products to treat and control Asian longhorned (Haemaphysalis longicornis) ticks in felines

MADISON, N.J., September 6, 2022 – 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 new label indication for both Bravecto® and Bravecto® Plus for the topical use in cats for the treatment and control of Asian longhorned tick infestations. Bravecto and Bravecto Plus for cats are the first and only U.S. products labeled for both the treatment and control of Asian longhorned tick infestations.

The Asian longhorned tick is an invasive Ixodid tick that is native to Japan, China, eastern Russia, and Korea. As of December 2021, the species has been located across more than one-third of the United States. These ticks have the potential to quickly become an important tick species within pet populations and are known for carrying various viral, bacterial, and protozoal agents.

“We’re committed to protecting pets and pet owners alike from parasites that pose risks to both animal and human health. With the new Bravecto and Bravecto Plus indication, we can expand our ability to care for pets by offering an even broader range of parasite protection for cats,” said Dominique Sims, DVM, associate director, scientific affairs, Merck Animal Health. “Veterinarians can now recommend a treatment option that provides more versatile protection than traditional flea and tick offerings, while giving cat owners peace of mind in knowing their pet is safe from infestations.”

The new indication adds to the already high level of protection provided by the topical treatments. Bravecto Topical Solution for Cats is indicated for all the following therapeutic areas:
Treatment and prevention of flea infestations
Treatment and control of black-legged ticks and Asian longhorned tick infestations for 12 weeks
Treatment and control of American dog tick infestations for 8 weeks

In addition, Bravecto Plus for Cats is indicated for all the following therapeutic areas:
Prevention of heartworm disease caused by Dirofilaria immitis
