Capstar Flea Tablets for Dogs and Cats

Many types of flea shampoos can be difficult to use on a cat because they involve submersing your cat in water.

This is why we have collected information to help you find an alternative to the dangerous route of bathing a cat by feeding them one Capstar Tablet for Cats.

Company Claims

These tablets are an oral treatment that kills fleas that are currently feeding on your cat. It starts working in 30 minutes but the effect only lasts for 24 hours.

The tablets are often combined with topical treatments to help prevent future infestations. It is a non-prescription treatment and should only be used as directed but can be repeated every 24 hours as necessary.

Active Ingredients

Capstar Tablets only have one active ingredient:

  • Nitenpyram

How Capstar Works

Nitenpyram is a neurotoxin that stops messages from travelling through the central nervous system. This causes the fleas to experience paralysis which leads to death within 24 hours. It has no harmful effects on mammals and is safe for use with cats that are lactating or pregnant.

Usage Information

The tablets are administered orally. You need to purchase the appropriate dosage based upon the weight of your cat. It should not be used on cats that are less than 4 weeks old or weigh less than 2 pounds.

You can repeat a dosage after 24 hours, but it is often better to follow up with a topical treatment to prevent future infestations.

What Are Users Saying About Capstar?

The many reviews available for Capstar Tablets for Cats were positive. There were only two negative reviews, both of which are easily corrected.

The first was about the tablet causing nausea in the cat. This is normally due to giving the cat the tablet on an empty stomach. Try to administer the dosage after the cat as eaten and this should mitigate this problem.

The other complaint was getting the cat to actually take the pill. While every cat is different, some cats have to be force fed pills. This can be difficult but there are several methods available from wrapping the cat in a towel to hiding the pill in their favorite treat. Experiment with what works best for you cat and ask your veterinarian if you are still having problems.

Side Effects and Precautions

The main side effect of this product for cats is the scratching that occurs as the fleas are dying. This is because the dead fleas are irritating the skin of your cat and should disappear within a few hours. If you are worried, then you can try to brush your cat with a stiff bristle brush. This will remove the dead fleas and give you cat the relief it needs from the itching.

There are other side effects, but these are extremely rare (1:100,000). They may include panting, lethargy, itching, vocalization, vomiting, fever, nervousness, diarrhea, salivation and seizures. If any of these occur, contact your veterinarian immediately.
