What is Bravecto?
Bravecto is a long-acting flea and tick treatment manufactured by MSD Animal Health (Merck). Its active ingredient is fluralaner, an isoxazoline compound that kills fleas and ticks by disrupting their nervous system.
For dogs, Bravecto is available as a pork-flavoured chewable tablet that provides 12 weeks of protection. This is a significant advantage over monthly treatments — just 4 doses per year instead of 12. For cats, it comes as a spot-on solution applied to the back of the neck.
Bravecto kills fleas within 8 hours and ticks within 12 hours of exposure. It does not cover worms, lungworm, heartworm or mites (except demodex in dogs at higher doses). If your dog needs worm protection, you will need a separate worming product alongside Bravecto.
Single dose lasts 3 months — only 4 per year
Chewable for dogs, spot-on for cats
Fleas and ticks only — need separate wormer
Bravecto Weight Bands
Cats: Bravecto spot-on for cats comes in two sizes: small cats (1.2-2.8 kg) and medium/large cats (2.8-6.25 kg). For cats over 6.25 kg, a combination of pipettes is used. Bravecto Plus for cats adds roundworm, hookworm and heartworm coverage.

Serious Side Effects (Rare)

Important Warnings
Seizure warning: Bravecto is an isoxazoline. Rare seizures have been reported. Not recommended for dogs with epilepsy or seizure history.
Long-acting: Because Bravecto lasts 12 weeks, if your dog has an adverse reaction, the drug cannot be quickly removed from the system. This is an important consideration.
Not for puppies under 8 weeks or dogs weighing less than 2 kg.
