Capstar Flea Tablets for Dogs 2-25 Lbs — Fast-Acting, 30-Minute Start | 6-Dose Pack

Capstar for Dogs: Fast-Acting Flea Control

Capstar (nitenpyram) provides quick flea control with an oral tablet designed for dogs and puppies weighing 2–25 pounds, starting from 4 weeks old. When dosed, fleas on contact with your pet can begin to die within roughly 30 minutes, giving you a fast, on-demand option during a flea challenge. This rapid action is especially helpful for pets dealing with sudden infestations or itchy days when you need a swift response.

What to Expect from a Single Dose

• Fast onset: fleas begin to decline within about 30 minutes after dosing.
• Noticeable effect: many pets show reduced flea activity within four hours.
• Visible results: you may observe dead fleas on your pet’s coat as the treatment works.

How Capstar Fits Into Your Flea Plan

• Easy, non-topical administration: a convenient oral tablet you can give directly or hidden in food.
• Over-the-counter: no prescription is required for dogs, 2–25 pounds, 4 weeks and older.
• Flexible dosing: if reinfestation occurs, a dose can be repeated once daily.
• Six-dose package: designed to support short-term containment during active infestations.

Real-life scenarios include pre-visit planning with a vet, responding to an unexpected flea surge after outdoor adventures, or needing a quick reset while you arrange a longer-term preventive plan. Capstar is straightforward to use and can help reduce flea presence quickly, which may help your dog feel more comfortable and less itchy as you tackle the broader flea-control routine.

Important notes

Capstar targets adult fleas and does not kill eggs or larvae. It is intended for dogs that weigh 2–25 pounds and are 4 weeks of age or older. If your dog takes other medications or has health concerns, consult your veterinarian before starting any new flea treatment regimen.
