NexGard SPECTRA

What is NexGard SPECTRA?

NexGard SPECTRA is a veterinary antiparasitic medication intended exclusively for dogs. It is available as an oral chewable tablet that most dogs readily accept thanks to its palatable flavour. Its formula combines two well-recognized active ingredients: afoxolaner and milbemycin oxime.
This combination provides broad-spectrum protection against several common parasites in dogs, both external and internal. Unlike treatments that require the use of multiple separate products, NexGard SPECTRA consolidates these protections into a single monthly tablet, making treatment adherence easier.
Used in many veterinary protocols across Canada, NexGard SPECTRA is designed to integrate seamlessly into a regular prevention routine while offering reliable antiparasitic coverage when prescribed by a veterinarian.

What is NexGard SPECTRA used for?

NexGard SPECTRA is used for the prevention and treatment of flea and tick infestations in dogs. In addition to its action against external parasites, it also protects against certain internal worms, including intestinal worms, due to the presence of milbemycin oxime.
By eliminating fleas, NexGard SPECTRA helps reduce itching, discomfort, and associated skin problems, including flea allergy dermatitis. Its action against ticks helps limit exposure to certain tick-borne diseases.
When administered regularly, NexGard SPECTRA supports a comprehensive preventive approach, ideal for dogs living in Quebec, whether they are highly active outdoors or primarily indoors.

Dosage

NexGard SPECTRA dosage depends on the dog’s weight. Selecting the correct presentation is essential to ensure optimal effectiveness and safe use. NexGard SPECTRA is available in several strengths, identified by distinct colours:

• Orange: dogs weighing 2 to 3.7 kg
• Yellow: dogs weighing 3.8 to 7.5 kg
• Green: dogs weighing 7.6 to 15 kg
• Purple: dogs weighing 15.1 to 30 kg
• Red: dogs weighing 30.1 to 60 kg

Each tablet contains a precise amount of afoxolaner and milbemycin oxime adapted to the indicated weight range. Tablets must not be split, and a presentation that does not match the dog’s current weight should not be used. Your veterinarian will determine the exact dosage at the time of prescription.

How and how often should I give NexGard SPECTRA to my pet?

NexGard SPECTRA is administered orally as a chewable tablet. It may be given directly as a treat or with a small amount of food if needed. Its palatable formulation generally makes administration easy, even for more selective dogs.
The dosing frequency is monthly. One tablet should be given once per month to maintain continuous protection against the targeted parasites. It is recommended to give the medication on the same date each month to minimize the risk of missed doses.
NexGard SPECTRA may be given with or without food. Always follow your veterinarian’s recommendations, particularly if your dog is receiving other medications or has specific medical conditions.

What are the side effects and precautions associated with NexGard SPECTRA?

NexGard SPECTRA is generally well tolerated by most dogs when used according to veterinary recommendations, but mild and temporary side effects may occasionally occur.
Possible effects may include:

• mild digestive disturbances such as vomiting, diarrhea, or temporary loss of appetite
• temporary fatigue
• rare skin reactions

It is important to respect the minimum age and weight requirements. Drug interactions may be possible, which is why informing your veterinarian of all ongoing treatments is essential. A veterinary assessment is recommended before use, especially in dogs with specific medical histories.
