Merck Animal Health referred over ‘inaccurate and misleading’ Bravecto Quantum claims

Merck Animal Health was referred to the FTC and FDA for 'inaccurate and misleading' dosing claims on its Bravecto Quantum flea and tick treatment for dogs. The NARB found the claims misleading as they imply year-long protection for all tick species, while the FDA-approved interval is eight months for the lone star tick. Merck plans to appeal part of the decision.
