Active Ingredients for Capstar for Large Dogs (No RX Required)

Nitenpyram (57mg): A fast-acting insect neurotoxin that safely interferes with the central nervous system of adult fleas, causing rapid termination without impacting mammalian receptors.

Because it leaves the body quickly, it can be administered safely to dogs and puppies from 4 weeks of age who meet the weight requirements, with zero fasting or special dietary changes required.

11.1 kg to 57 kg	Green Pack (Large Dog)	1 Tablet	Daily (or as required when fleas are seen)
Over 57 kg	Green Pack (Large Dog)	2 Tablets	Daily (or as required when fleas are seen)

Frequently Asked Questions

Can I purchase Capstar for Large Dogs without a vet prescription?

Yes, you can buy Capstar for Large Dogs without a vet prescription. It is an over-the-counter flea control medication, meaning you can legally buy it online directly from Smartway Pet Supplies without paying for a clinic check-up or prescription script.

How often can I give Capstar to my dog?

Capstar is gentle enough for daily use. If your dog goes to a park or boarding kennel and returns with a fresh batch of fleas, you can safely give them a tablet every single day until the active environmental infestation is entirely brought under control.

Does Capstar protect against heartworm or intestinal worms?

No, Capstar is a highly specialized treatment engineered strictly for adult fleas. It does not treat heartworms, ticks, or intestinal worms. For complete broad-spectrum protection, combine Capstar with an allwormer like Cazitel.

How long does a single dose of Capstar stay active in my dog's system?

Capstar works as a rapid flush treatment. It actively clears the adult fleas currently biting your dog within 24 hours. Because it metabolizes out of the system quickly, it does not provide a month-long residual shield, which is why a secondary monthly treatment is recommended for ongoing defense.
