Capstar For Dogs

Capstar contains the same active ingredient (nitenpyram) as Capguard and is generally considered the “brand-name” of this medication.

Application:

Available as tablets for oral administration, you can either “pill” your pet if they tolerate this or you can mix it with their favorite treat to ensure they eat it all.

What does it kill?

Capstar contains nitenpyram as the active medication which kills adult fleas.

How does it work?

These oral tablets are digested and the active ingredient, nitenpyram absorbed through the lining of your pooch’s small intestine into their bloodstream and around their body. Once an adult flea bites, they ingest this ingredient which kills them through it’s action on their nervous system.

How long does it last?

Short-acting, Capstar’s active ingredient remains in the body for up to 24 hours after administration.

Active Ingredient

Nitenpyram, this drug kills adult fleas before they’ve had the opportunity to lay eggs in your pooch’s fur.

How Are the Ingredients in Capstar Delivered?

As an oral medication the medication is distributed through your pet’s body and fleas need to bite in order to be exposed and killed. Nitenpyram targets nerve signaling in the flea’s body causing death.

How long does it take for Capstar to start working?

Capstar gets to work within 30 minutes of administration. Just one tablet can kill over 90% of fleas within 4 hours on your pooch.

Safety, Risks, and Possible Side Effects of Capstar

There are risks with all products and Capstar is no different in this way, though luckily adverse effects are rare and short-lived. This is in part due to the short duration of action of nitenpyram which is eliminated from your pet’s system in 24 hours. Side effects include lethargy, tummy upsets, and possibly some neurological signs though these are exceptionally rare.

What we like about it 

  1. Suitable for puppies just 2lbs and 4 weeks old
  2. Fast-acting within just 30 minutes
  3. Can kill over 90% of fleas within just 4 hours

What we don’t like about it  

  1. Fleas need to bite your pet in order to be exposed to the product
  2. The short duration of action means you need to give a tablet daily for complete protection
3/5

Our Rating:  3 out of 5! Capstar is a great product if you need an extra top-up to your usual parasite protocol for your pooch but some pets refuse to take tablets even hidden in their favorite treats which can make it difficult if you need to give the medication daily. It’s excellent for small puppies just 4 weeks old if you discover fleas. Once the pup is over 2lbs weight you can give them this medication to kill any fleas they may have as flea infestations in puppies can be life-threatening.

As always, any pet can suffer an adverse effect from medication so you should speak with your veterinarian before trying any new flea treatment for your fur-baby. This is particularly important if your pet has any health concerns or takes any regular medications. If your pet suffers a reaction then you should contact your veterinary surgery as soon as possible.

Our Rating:  3 out of 5! Capguard is a great product if your pet has just been exposed to a high flea burden and have possibly missed their usual preventative dose or for some pawrents that are concerned about pharmaceuticals in their fur-babies bodies.

Both products are safe enough to be given to puppies as young as just 4 weeks of age once they weigh over 2lbs.

Ease of Use

As oral tablets, their ease of use depends on how good your pet is with tablets. Neither of these tablets are flavored or chewable so you need to either “pill” your pet or hide the medicine in their favorite treat.

Coupled with needing to be administered daily as required, this can cause a lot of stress in some homes.

Capstar vs Capguard Final Thoughts

Capstar vs Capguard Final Thoughts

There’s not a huge difference between either of these flea treatment products, both are similar prices and contain the exact same concentrations of the same active ingredient, nitenpyram.

Choosing between Capstar vs Capguard will depend on how you feel about ‘generic vs brand’ medications.

Generic products must contain the same active ingredient in a similar concentration to the brand-name product and Capguard meets this requirement and matches Capstar in both onset and duration of action.

Either one of these products can be used to provide fast relief and killing power against active flea infestations in your pet but they are cumbersome to use as preventative due to the need to administer a tablet every 24 hours.
