NexGard vs. Simparica: How Are They Different?
There are several differences between NexGard and Simparica that may be a factor in determining which one is the best suited for your dog.
Some of these differences are:
Which Treatment Is More Effective?
While belonging to the same class of pesticides, i.e., the isoxazolines, the active ingredients in NexGard and Simparica tablets are different.
NexGard is based on Afoxolaner, while Simparica has Sarolaner as the active ingredient.
Both are effective ingredients for offering treatment against fleas and ticks.
However, the difference lies in the time they take to spring into action and the efficacy against different species of ticks.
NexGard tablets kill fleas within 4 hours and ticks in about 24 hours.
Simparica tablets take about 3 hours to eliminate fleas and about 8 hours to eliminate ticks. According to DailyMed, Simparica is 96.2% effective even on the 35th day of treatment1.
When comparing NexGard to Simparica Gulf Coast ticks could be a deciding factor.
While Gulf Coast ticks are not common in dogs, there is still a chance of your four-legged companion getting infested with them.
NexGard is ineffective against Gulf Coast ticks, while Simparica offers effective treatment against them2.
On the other hand, NexGard tablets are also effective in getting rid of eggs and larvae of fleas. Simparica falls short in this regard.
Treatment Against Other Parasites
In addition to the original Simparica tablets, the brand offers another product under the name of Simparica Trio, which has all the features of original Simparica chewable tablets and more.
In addition, Simparica Trio offers treatment against other parasites such as roundworms, hookworms, and heartworms.

Tablet Use for Younger Pups

NexGard is safe to use for dogs who are at least two months old and weigh 4 lbs or more.
Simparica is meant for dogs six months or older and those who weigh at least 2.8 lbs or more.
Safety Precautions For Breeding, Pregnant or Lactating Dogs
In addition to considering the age and weight of dogs, NexGard and Simparica brands have different safety profiles regarding breeding, pregnant or lactating animals.
Both the brands are approved by the FDA for general usage. However, Simparica was evaluated and marked as unsuitable for breeding or pregnant dogs.
NexGard has not been assessed yet for dogs in these conditions.
Protection Against Lyme Disease
NexGard was the first treatment that was approved by the FDA when it comes to protection against infections that can cause Lyme disease in your pet.

Final Thoughts On the NexGard vs. Simparica Comparison
Both NexGard and Simparica tablets for dogs have some pros and cons.
The choice of the treatment depends mainly on the age, weight, and condition of your dog.
Both of these treatments are available for purchase after a prescription is provided by a veterinarian. Don’t have a prescription? You still have flea-treatment options.
Since Simparica is not safe to use for dogs younger than six months, many pet owners choose to go with NexGard and later shift to Simparica when their puppies are old enough.
In any case, you should always consult a professional first.
The vet will examine your pet and help you decide which treatment is best for your dog, depending on the circumstances.
