Description
Bravecto Chews For Dogs 4.4-9.9 Lbs (2-4.5 Kg) contain fluralaner (112.5 mg), an isoxazoline-class ectoparasiticide manufactured by MSD Animal Health . Each chewable tablet delivers systemic flea and tick protection for 12 weeks, eliminating the need for monthly dosing. Fluralaner is absorbed into the bloodstream after oral administration and kills fleas and ticks when they feed on the treated dog.
Recommended for: Dogs weighing 4.4 to 9.9 lbs (2 to 4.5 kg), from 6 months of age.
Indication/Coverage:
For dogs weighing 4.4 to 9.9 lbs (2 to 4.5 kg) suffer from, or at risk from, mixed parasitic infections:
- Flea treatment and prevention: Kills adult fleas (Ctenocephalides felis and Ctenocephalides canis) within 8 hours of attachment, with persistent activity for 12 weeks.
- Black-legged tick control: Treatment and control of Ixodes scapularis infestations for 12 weeks; this species is the primary vector of Lyme disease in the northeastern and upper midwestern United States.
- American dog tick control: Treatment and control of Dermacentor variabilis for 12 weeks ; this species transmits Rocky Mountain spotted fever.
- Brown dog tick control: Treatment and control of Rhipicephalus sanguineus for 12 weeks ; effectively controlled at the adult stage with efficacy confirmed at 48 hours post-infestation.
- Asian longhorned tick control: Treatment and control of Haemaphysalis longicornis for 12 weeks ; an invasive species established in multiple U.S. states with demonstrated efficacy at 48 hours.
- Lone star tick control (6 months and older only): Treatment and control of Amblyomma americanum for 8 weeks in dogs 6 months of age and older; not effective in puppies under 6 months for this species specifically.
- Flea Allergy Dermatitis (FAD) management: Can be incorporated into a treatment strategy for controlling FAD by eliminating flea populations before sensitized dogs develop allergic reactions.
- Environmental flea control: Newly emerged fleas on a treated dog are killed before producing viable eggs, which disrupts the flea life cycle in areas the dog frequents.
- Reduce the risk of tapeworm infections and tick-borne diseases by effectively controlling intermediate hosts.
Key Benefits:
The following characteristics distinguish this product based on its label data:
- Puppy and small-breed suitability: Formulated for dogs as young as 6 months and as light as 4.4 lbs (2 kg), delivering a fluralaner dose of 25 to 56 mg/kg within this weight band.
- Broad ectoparasite spectrum: A single dose addresses adult fleas (Ctenocephalides felis) and five tick species: Ixodes scapularis, Dermacentor variabilis, Rhipicephalus sanguineus, Haemaphysalis longicornis, and Amblyomma americanum in dogs 6 months of age and older.
- Systemic mechanism of action: Fluralaner is absorbed into the bloodstream and distributed throughout the body. Parasites are exposed when they commence feeding, so external contact or coat condition does not influence efficacy.
- Rapid onset: Flea killing activity begins within 8 hours of flea attachment; tick killing activity begins within 12 hours of tick attachment.
- 12-week duration per dose: Each tablet provides persistent protection for 3 months, reducing the dosing frequency to four treatments per year compared to monthly alternatives.
- Lifecycle disruption: Fleas on a treated dog are killed before they can produce viable eggs. This breaks the flea life cycle and progressively reduces environmental flea burden in the dog’s living area.
- Chewable oral format: The pork flavored tablet is accepted voluntarily by most dogs, which removes the need for topical application, drying time, or separation from other pets after dosing.
- Resistance profile: In laboratory assays, fluralaner retains efficacy against flea and tick populations carrying documented field resistance to amidines, organophosphates, cyclodienes, phenylpyrazoles, pyrethroids, and carbamates.
Caution:
Hazards to Humans
Keep Bravecto in its original packaging until use to prevent children from gaining direct access. Do not eat, drink, or smoke while handling the tablet. Wash hands thoroughly with soap and water immediately after administration.
Hazards to Domestic Animals
Bravecto Chews are for oral administration to dogs only. This 112.5 mg variant is formulated for dogs weighing 4.4 to 9.9 lbs (2 to 4.5 kg), aged 6 months or older. Do not administer to puppies under 6 months of age or dogs under 2 kg, as safety data for these populations is not available. Dogs that are debilitated, aged, pregnant, or nursing should be assessed by a veterinarian before treatment, although reproductive safety has been demonstrated in breeding, pregnant, and lactating dogs. Rare individual sensitivity reactions, including lethargy and muscle tremor, have been reported in post-market surveillance. No drug interactions with routinely used veterinary products were identified during clinical field testing, though fluralaner is highly protein-bound and could theoretically compete with other highly bound drugs such as NSAIDs and warfarin.
Possible Side Effects:
Monitor your dog after administration of Bravecto Chews, particularly following the first dose.
Gastrointestinal reactions: Mild and transient diarrhea, vomiting, decreased appetite, and drooling were observed in 1.6% of dogs during clinical studies. These signs are associated with the oral route of administration and typically resolve without intervention.
Systemic signs: Lethargy, pruritus (itching), muscle tremor, ataxia (loss of coordination), and convulsions have been reported in post-market surveillance at very rare frequency. Most reported reactions were self-limiting and of short duration.
Isoxazoline class warning: The FDA issued a 2018 alert requiring all isoxazoline products, including Bravecto, to carry label warnings for potential neurological adverse events such as tremors, ataxia, and seizures. Dogs with a history of seizures or pre-existing neurological conditions should not receive Bravecto without prior veterinary clearance.
If your dog exhibits any unusual signs after taking Bravecto, consult your veterinarian promptly.
