Frequently Asked Questions on Nexgard Spectra 

How does Nexgard Spectra work?

NexGard Spectra combines two active ingredients – afoxolaner and milbemycin oxime – to offer broad spectrum control of the most common external and internal parasites of dogs in one convenient monthly treat.

It kills fleas within 6-8 hours following administration. The rapid onset of action ensures fleas are killed before they can lay eggs, making it an effective solution for medium-to-heavy infestation too. To combat reinfestation and to prevent further contamination of the environment with eggs, monthly use is recommended.

NexGard Spectra also provides effective control of pre-existing paralysis ticks within 24 hours.

NexGard Spectra is an ideal choice for dogs with flea allergy dermatitis, due to its rapid speed of kill and month long efficacy. Also, because it is a vegetable-based chew with soy proteins, it will not trigger beef allergies.

This monthly treatment is safe for puppies from just 8 weeks of age, providing they weigh at least 2kg. It has also been shown to be well tolerated in over 100 different pure breeds and a wide range of cross breeds, including Collies and Shepherd breeds (which are particularly sensitive to some drugs due to mutations in their genes). 

Unlike some sprays, spot-on formulations or collars, dogs may be handled immediately following dosing, and there are no restrictions on swimming and bathing before or after administration. Your dog can do anything – even play with children – straight after dosing!


How do I use NexGard Spectra?

NexGard Spectra is a soft beef-flavoured chew that is for oral consumption only. You can choose to give with or without food, whichever is most convenient.

Remove only one chewable at a time from the blister card. You can offer it as a treat at any time, or, it can be broken into pieces and fed to your dog in a small amount of dog food.

NexGard Spectra will provide effective protection for a complete month, so it is not necessary to treat more than once a month. To ensure your dog is always covered, aim to dose your dog on the same day every month.

NexGard Spectra is available in five chew sizes and comes in a range of sized packs for your convenience and cost efficiency.


How long does NEXGARD SPECTRA protect my dog from fleas and ticks?

NEXGARD SPECTRA will protect your dog from fleas and the most problematic tick species infesting dogs in Australia (Brown Dog tick, Bush tick and the deadly Paralysis tick) for a full month.


How does NEXGARD SPECTRA kill fleas?

NEXGARD SPECTRA kills fleas by over-stimulating their nervous system resulting in hyperexcitation and death. Following administration, fleas are killed within 6–8 hours. The rapid onset of action kills newly acquired fleas before they can lay eggs. Monthly use is recommended to combat reinfestation and prevent further contamination of the environment with eggs.
