How long does the Bravecto tablet for dogs work against ticks? - in detail
Bravecto chewable tablets for dogs deliver systemic tick control for a period of twelve weeks after a single dose. The active ingredient, fluralaner, circulates in the bloodstream and targets ticks that attach to the host, killing them within 12 hours of attachment. Because the compound remains at therapeutic concentrations for three months, any tick that feeds during this interval is eliminated before it can transmit disease.
Key pharmacokinetic facts:
- Peak plasma concentration occurs 2–4 days post‑administration.
- Therapeutic plasma levels persist for at least 84 days.
- Efficacy is maintained against all common tick species, including Ixodes ricinus, Dermacentor variabilis and Rhipicephalus sanguineus.
Factors influencing the protection window:
- Body weight: dosage is calibrated to ensure adequate fluralaner exposure across the approved weight range (4.4 kg – 22 kg).
- Health status: severe hepatic or renal impairment may alter drug metabolism, potentially shortening the effective period.
- Concurrent medications: certain enzyme‑inducing drugs can reduce fluralaner concentrations, warranting veterinary assessment.
When a twelve‑week interval elapses, a new tablet should be administered to re‑establish systemic protection. Regular veterinary monitoring ensures optimal timing and confirms continued efficacy against evolving tick populations.
