Zap! (nitenpyram)

Zap! is an oral capsule for dogs, puppies, cats and kittens 4 weeks of age and older and 2 pounds of body weight or greater.

Active Ingredients

Zap! capsules contain 11.4 or 57.0 mg of nitenpyram, which belongs to the chemical class of neonicotinoids. Nitenpyram kills adult fleas.

Directions

A single dose of Zap! 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 Zap! capsules, place the pill directly in your pet’s mouth or open and mix with food. 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.

Other Information

Zap! begins working within 15-30 minutes. In studies, nitenpyram achieved greater than 90% effectiveness against adult fleas on dogs within 4 hours and cats within 6 hours. Zap! is 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.

Zap! kills adult fleas that cause flea allergy dermatitis (FAD). Also, fleas transmit other parasites, including tapeworms. The control of flea infestations is important to your pet’s health and also reduces the problems associated with these parasites.

Zap! may be used together with other products, including heartworm preventives, corticosteroids, antibiotics, vaccines, de-worming medications, shampoos and other flea products.

Zap! does not affect fleas in the pet’s environment. You may need to treat more than one time because immature fleas in and around the home will continue to develop into adults that can reinfest your pet.

In addition to killing adult fleas with Zap!, you can treat your pet with an insect development inhibitor like lufenuron to prevent and control flea populations.

NADA #141-175, Approved by FDA.

    These pills are amazing. They kill all the live fleas quickly and keep killing any that hatch or jump on the animal for 24 hours.

    Best Fast Flea Killer Ever

    Repeat customer. I have purchased this product several times over the last few years. I recommend it to anyone that has issues with fleas on their pets. We use it for our cats and double the dose for our big dog. Compare the active ingredient I'm Zap! to leading flea treatment brands. It is the same!! Happy to support this small American owned business!

    This stuff is AMAZING! It works quick. My cats are used to getting a cat lickable treat every morning so now I squeeze it into 2 tablespoons and break open the capsule to put the powder on top. They lap it right up!!
