NEXTSTAR Flea & Tick Topical for Dogs 45-88 lbs – 3-Month Supply

Larger dogs need protection that actually holds up to their size, and NEXTSTAR is built for that — a fast-acting topical that starts working on contact within 5 minutes, with full coverage settling in over the next 24-48 hours. Made by the team behind CAPSTAR, this formula was once vet-exclusive and is now available directly, no prescription required.

It handles fleas, ticks, mosquitoes, and chewing lice, but the part that actually stops an infestation from coming back is the flea-egg and larvae control — one monthly dose interrupts the flea life cycle before it has a chance to restart. That's the difference between treating what you can see and actually getting ahead of it.

The topical formula is waterproof and works through direct contact, so it stays effective through baths and rain. Each application lasts 30 days, and this pack covers a full 3 months — sized specifically for dogs in the 45-88 lb range.

Active Ingredients: Fipronil, Cyphenothrin, (S)-Methoprene
