NEXTSTAR Flea & Tick Topical for Dogs 23-44 lbs – 2-Pack, 3-Month Supply
Most flea treatments ask you to wait days to see results — NEXTSTAR starts killing fleas within 5 minutes of application, with full nose-to-tail protection kicking in over the following 24-48 hours. From the makers of CAPSTAR, this formula was previously only available through vet offices and is now sold without a prescription.
It offers 7-way protection: fleas, ticks, mosquitoes, chewing lice, flea eggs, flea larvae, and flea pupae development. That last part matters for actually breaking a flea infestation rather than just killing the adults you can see — a single monthly application interrupts the whole life cycle, not just the visible symptom.
Application is topical and waterproof, working through direct contact so pests don't even need to bite your dog for it to take effect. One application covers 30 days; this 2-pack gives you a full 3-month supply, sized for dogs weighing 23-44 lbs.
Active Ingredients: Fipronil, Cyphenothrin, (S)-Methoprene
As with any flea/tick treatment, apply only to the weight range specified on the packaging, and consult your veterinarian before use if your dog has a known sensitivity or existing health condition.
Real people. Real tails.
