Capstar® Tablets for Dogs

This medicine is an oral tablet for dogs that kills adult fleas quickly. It provides same-day relief and may be used alongside a monthly preventive when a veterinarian agrees. You can review Canadian pricing without insurance here.

What Capstar Is and How It Works

US shipping from Canada is available for this product through Borderfreehealth. Capstar® contains nitenpyram, a fast-acting oral flea adulticide for canine use. After swallowing a tablet, it circulates in the bloodstream and targets the flea’s nervous system. It starts reducing live adult fleas on your dog the same day, helping your home program get ahead of the problem. Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

Fleas feed and reproduce quickly. This treatment works on adult fleas that are biting your dog, which can reduce scratching and visible pests. It does not replace environmental control or longer-acting preventives. Pairing it with a monthly plan and home cleaning can improve overall flea management. Learn more about the condition at our Flea Infestation page.

Who It’s For

This treatment is for dogs and puppies that need rapid adult flea knockdown. Many households use it when they first notice fleas, after a shelter intake, or during seasonal spikes. Capstar for Puppies is generally suitable for young dogs that meet age and weight thresholds; follow your veterinarian’s guidance for growing pets. Dogs with a known sensitivity to nitenpyram, or those below labeled age/weight minimums, should not use it.

Senior dogs, pregnant or nursing dogs, and dogs taking other parasite preventives can often use this class of medicine, but your veterinarian is the best source for individual recommendations. If your dog has a seizure history or takes drugs that affect the nervous system, ask about risks and benefits first.

Dosage and Usage

This is a single-dose oral tablet given by mouth when adult fleas are present. Many pet owners offer the tablet by hand, hide it in a small treat, or crumble it into a small amount of food. If crumbled, watch to ensure the entire dose is consumed. Water is allowed. The tablet can be given with or without a small meal unless your veterinarian advises otherwise.

Nitenpyram for Dogs is labeled for weight-based dosing using the appropriate tablet size. A single full tablet is given once, and the dose may be repeated once daily if fleas continue to be seen. If your dog vomits shortly after dosing, contact your veterinarian for guidance on whether another dose is needed. Always read the package insert for the exact labeled directions.

Because this therapy targets adult fleas only, many veterinarians recommend also using a monthly preventive that interrupts the lifecycle. Continue household cleaning, such as vacuuming and washing pet bedding, to manage eggs and larvae in the environment.

Strengths and Forms

Capstar Tablets for Dogs are available as oral tablets in two commonly used strengths and in cartons that often contain multiple tablets. Availability and pack counts can vary by market.

• Oral tablet presentation
• Boxes often include several doses for short-term use

Please check the specific listing for current packaging. Strength selections are based on your dog’s weight as outlined on the label. If you are unsure which tablet belongs to your dog’s weight range, ask your veterinarian before you order.

Missed Dose and Timing

This treatment is usually given as needed. If a planned dose is missed during an active infestation, give it when remembered and then continue your broader flea plan. Do not give more than one full dose per day. If you use two weight-based sizes in your home, avoid mixing them between pets. Mention of Nitenpyram 57mg here reflects a common tablet strength for larger dogs; follow labeled directions for your dog’s weight range.

Storage and Travel Basics

Store tablets in the original blister until use. Keep in a dry place at room temperature, away from moisture and direct light. Secure all medications out of reach of children and other pets. When you travel, keep the carton or a copy of the package insert with the tablets so you can show what you are carrying. Place tablets in your carry-on to avoid extreme temperatures. For international travel with pets, your veterinarian can provide documentation that lists current parasite control.

Benefits

Capstar Flea Tablets for Dogs offer rapid adult flea knockdown without a topical application. Many owners appreciate the lack of residue and the flexibility to use it on a day when fleas are seen. Because it is oral, bathing or swimming does not reduce its direct effect on adult fleas currently feeding.

This class of medicine can complement monthly preventives that target eggs, larvae, and future adult fleas. Using both strategies may help manage reinfestation pressure in homes and yards. It can also support comfort during the wait for a longer-acting monthly dose to take effect.

Side Effects and Safety

• Temporary itching or scratching
• Restlessness or hyperactivity
• Panting or increased heart rate
• Vomiting or soft stool
• Reduced appetite
• Lethargy

Most effects are mild and short-lived. Serious reactions are uncommon but can include seizures, severe vomiting, or signs of hypersensitivity. If your dog shows concerning symptoms, seek veterinary care. Dogs with a seizure history or certain neurologic conditions may need closer monitoring. Keep all parasite products out of reach of children.

Drug Interactions and Cautions

Nitenpyram does not have many well-known drug interactions, but caution is appropriate when multiple parasite control products are used together. Tell your veterinarian about all supplements and medicines your dog receives. If your dog is pregnant, nursing, or has chronic conditions, discuss the overall plan before starting. Stop the tablet and contact a veterinarian if your dog experiences a severe reaction after dosing.

What to Expect Over Time

Pet owners usually notice fewer adult fleas on their dog the same day a dose is given. You may still see fleas for a while as eggs in the environment hatch and new adults emerge. Combining this medicine with a monthly preventive and home cleaning can improve results over weeks. Consistency matters: give a tablet on days when adult fleas are seen, and keep up with your longer-term plan to break the lifecycle.

Tracking your dog’s scratching, visible fleas, and any reactions in a notebook or app can help you and your veterinarian adjust the broader plan. If you do not see progress, ask whether a different preventive or environmental step would help.

Compare With Alternatives

Some households prefer a monthly topical that targets multiple stages of fleas and other parasites. For a broad-spectrum option, see Revolution For Dog. For young pets in multi-pet homes, you may consider Revolution For Puppies Kittens under veterinary guidance. If you need a different pack presentation, review Capstar For Cat Dog for multi-species households after confirming weight and species directions.

Pricing and Access

You can compare Canadian options with US delivery from Canada on Borderfreehealth. Many families use cash-pay for short-term flea control; check our current listing instead of calling around locally. Buy Capstar for Dogs if it fits your veterinarian’s plan, or consider a monthly preventive to limit reinfestation. For general savings opportunities and any active codes, visit our Promotions page.

Availability and Substitutions

Stock can vary by strength and pack size. If your preferred option is unavailable, a veterinarian may recommend an alternative adult flea product or a monthly preventive as part of a comprehensive plan. We do not provide restock dates, but you can check back for updates or consider another labeled product.

Patient Suitability and Cost-Saving Tips

This tablet suits dogs that need immediate adult flea reduction and households that prefer an oral option. It may be less suitable for dogs with certain neurologic conditions or those below the labeled age or weight. Ask your veterinarian about using it with your dog’s other preventives, especially during heavy flea seasons.

To save, consider ordering a multi-month supply in one parcel if you anticipate repeated dosing during peak months. You can set calendar reminders for refills so you have tablets on hand when fleas appear. Combining this tablet with environmental control can also reduce the number of doses you need over time.
