Frequently Asked Questions (FAQs)
Q: What makes NexGard’s mechanism of action unique?
A: NexGard contains afoxolaner, an isoxazoline chemical, that targets the nervous systems of fleas and ticks, causing hyperexcitation and, eventually, their death. Its efficacy remains consistent throughout the entire month, providing long-lasting protection.
Q: Are there any specific breeds sensitive to Revolution or NexGard?
A: While both Revolution and NexGard are generally safe for all breeds, certain drugs in the isoxazoline class (like afoxolaner in NexGard) have been associated with adverse reactions in dogs with a history of seizures. Always discuss any breed-specific concerns with your veterinarian.
Q: How quickly do these medications start working after administration?
A: NexGard begins killing fleas approximately 4 hours after ingestion, and it achieves over 99% efficacy in 8 hours. Revolution, on the other hand, starts killing fleas within 36 hours of application.
Q: Is resistance to these medications a concern?
A: To date, there’s no widespread evidence of flea or tick resistance to either NexGard or Revolution. Nonetheless, rotating between different classes of preventatives annually can help reduce the chances of resistance developing.
