Frequently asked questions

NEXGARD SPECTRA Spot-On Solution for Cats is a parasiticide (i.e. something that kills parasites). It is a liquid containing three active ingredients, applied in one spot on the cat’s neck, to kill worms and mites, and provide month long protection against fleas and ticks.

No.  NEXGARD SPECTRA for Cats is effective against roundworms, hookworms, lungworms and tapeworms and therefore an oral worm pill is not needed

There are three active ingredients in NEXGARD SPECTRA for Cats. Esafoxolaner targets fleas, ticks and mites; eprinomectin targets lungworms, hookworms, and roundworms; and praziquantel targets tapeworms. Each ingredient works in a slightly different way on the target parasite, but broadly speaking, they work by causing the parasite to be unable to regulate their own nervous systems, resulting in the parasite’s death. 

There are two good reasons – first, NEXGARD SPECTRA for Cats is the most comprehensive parasiticide available for cats in New Zealand, so you can treat for all the main external parasites and internal worms of concern in one simple treatment. The second reason is the monthly treatment intervals. This is perfect for protecting against roundworm which is a significant risk to human health and can pass from cat to human. It takes a roundworm just five weeks to mature and start laying eggs, so monthly treatment stops that. If you leave it longer than five weeks to treat for worms again, that gives the roundworm the opportunity to lay eggs – up to 200,000 per day!

NEXGARD SPECTRA for Cats will start working within just a few hours of administration. Like all flea treatments, a flea must be exposed to the product in order to be killed. Fleas that jump on your cat will die within 24 hours, before they can reproduce and lay eggs. It is important to understand that only 5% of the flea population lives on pets. The remaining 95% lives in the environment and that means your cat can pick up new fleas when they go out exploring. However, regular monthly treatment will keep your cat protected and prevent flea infestations happening in the home.

To apply NEXGARD SPECTRA for Cats pull back the plunger slightly, remove the cap, place the tip of the applicator on the skin. Apply the contents directly on the skin in one spot on the midline of the neck between the base of the skull and the shoulder blades. Refer to the label insert before use.

Yes, NEXGARD SPECTRA kills fleas rapidly before they lay eggs, therefore preventing further infestation of the environment. If a moderate to heavy environmental infestation exists, fleas can continue to emerge into the surroundings for weeks to months because of the continuing development of flea eggs, larvae and pupae already present at the time of treatment. It may therefore take more than one monthly treatment to achieve control of moderate to heavy flea infestations. In areas where fleas are common year-round, monthly treatment should continue throughout the year without interruption. To minimise the likelihood of flea re-infestation, it is important to treat all animals within a household with an approved flea control product. See product label for full claim details and usage instructions.
