Fast Tabs

Fast Tabs (Nitenpyram) is an oral tablet for dogs, puppies, cats and kittens 4 weeks of age and older and 2 pounds of body weight or greater.

Active Ingredients: Fast Tabs Tablets contain 11.4 or 57.0 mg of nitenpyram, which belongs to the chemical class of neonicotinoids. Nitenpyram kills adult fleas.

Directions: Fast Tabs kill adult fleas and are indicated for the treatment of flea infestations on dogs, puppies, cats and kittens 4 weeks of age and older and 2 pounds of body weight or greater.

A single dose of Fast Tabs should kill the adult fleas on your pet. If your pet gets re-infested with fleas, you can safely give another dose as often as once per day.

To give Fast Tabs, place the pill directly in your pet's mouth or hide it in food. If you hide the pill in food, watch closely to make sure your pet swallows the pill. If you are not sure that your pet swallowed the pill, it is safe to give a second pill.

Treat all infested pets in the household. Fleas can reproduce on untreated pets and allow infestations to persist.

Dosage: Fast Tabs Tablets should be administered according to the following schedule. Weigh your pet prior to asministration to ensure proper dosage. Do not administer to pets under 2 pounds.

Recommended Dosage Schedule

Species                Body Weight           Dose            Nitenpyram per tablet        
Dog or Cat              2-25 lbs.            One tablet                  11.4 mg
Dog                       25.1-125 lbs.       One tablet                   57.0mg

Adverse Reactions: Laboratory and clinical studies showed that Fast Tabs are safe for use in dogs and cats, puppies and kittens 4 weeks of age and older and 2 pounds of body weight or greater.

Other Information: Fast Tabs Tablets begin working within 30 minutes. In studies, Fast Tabs achieved greater than 90% effectiveness against adult fleas on dogs within 4 hours and cats within 6 hours.

Fast Tabs are safe for pregnant or nursing dogs and cats.

When using this product, you may notice that your dog or cat will start scratching itself as fleas begin to die. The scratching behavior is temporary and is a reaction to the fleas, not the drug. In very rare cases in cats, this may present as transient signs of hyperactivity, panting, vocalization and excessive grooming.

Fast Tabs Tablets kill adult fleas that cause flea allergy dermatitis (FAD).

Fast Tabs Tablets may be used together with other products, including heartworm preventatives, corticosteroids, antibiotics, vaccines, de-worming medications, shampoos and other flea products.

Storage Conditions: Store at controlled room temperature between 59° and 77°F (15-25°C).

This is a great product !!!!! It really helps people like me that feed cat colonies. Some of the cats are feral and you can't get near them put on drops, so I can put this in their food and no worries.....

It's truly amazing!

I went to the vet for my Pomeranian and the vet gave it to him there. By the time we got home about less than an hour later I looked at his belly and back there was no more flea dirt. Also I could hardly see the any fleas maybe one or two. After a few more hours I noticed he was not scratching at all. I have never seen anything work this fast. Amazing product.

I never thought I can save more by getting this product rather than the name brand, I think this works pretty well on my dogs so far.

Good job!

I just ordered this last month and received them withing the given expected date. I am trying this Generic version of Capstar hoping to save a penny but works as described. I'm giving this 5 stars because of the price and the reasonable shipping. I may write another review after a few weeks if this is effective.

Great prices!
