Frequently Asked Questions

How long does Bravecto last for dogs?
The Bravecto chewable tablet provides flea and tick protection for 12 weeks (approximately 3 months), making it one of the longest-lasting oral flea and tick products available. The topical formulation is applied monthly. This extended duration means fewer doses per year compared to monthly products.
Can Bravecto cause seizures in dogs?
The FDA has reported that isoxazoline products, including Bravecto, may cause neurological adverse events such as seizures, tremors, and ataxia in some dogs. Dogs with a history of seizures or neurological disorders may be at higher risk. Discuss your dog's medical history with your vet before starting Bravecto.
Does Bravecto need to be given with food?
Yes, Bravecto chewable tablets should be given with food or at mealtime. Giving with food significantly improves absorption of the active ingredient fluralaner, ensuring optimal flea and tick protection for the full 12-week period.
What if my dog vomits after taking Bravecto?
If your dog vomits within 3 hours of taking Bravecto, the dose may not have been fully absorbed. Contact your veterinarian, who may recommend re-dosing. Giving Bravecto with a full meal helps reduce the chance of vomiting and improves absorption.
Does Bravecto kill ticks already on my dog?
Yes, Bravecto begins killing ticks within 12 hours of administration and fleas within 2 hours. It kills existing parasites as well as new ones that jump on your dog throughout the 12-week protection period. However, ticks may still briefly attach before being killed.
