NexGard Reviews | What is NexGard?

NexGard® was created by Merial, now a part of Boehringer Ingelheim, a global pharmaceutical company focused on improving animal health. Merial also created the Frontline® brand of flea and tick medication, with billions of doses administered around the world.

NexGard flea and tick pills, in fact, the very first chewable pest medicine for dogs, making it easy for dogs to get protected against pests each month.

NexGard flea and tick pills can be taken by dogs and puppies that are at least 8 weeks of age and weigh at least 4 pounds. It has not been determined if NexGard is safe for pregnant, breeding, or lactating dogs.

How Long Does NexGard Last?

NexGard is designed to last for thirty days at a time, providing dog owners with the convenience of month-to-month protection.

How Fast Does NexGard Work?

According to the product website, it does not take long for NexGard to start working, as the medication works quickly to kill all fleas and ticks within 24 hours.

Many reviews from veterinarians and consumers support this statement, with only a few NexGard reviewers reporting that it took an extra 24 hours for the NexGard flea and tick pill to start showing results.

What is the NexGard Active Ingredient?

Afoxolaner is the active ingredient in NexGard, an insecticide and acaricide which travels through your dog’s bloodstream and kills pests by over-stimulating their central nervous system.

NexGard Reviews | Where Can I Find the Best NexGard Price?

As with any medical treatment, NexGard prices will be a consideration for pet owners to take when choosing the right flea and tick medication for their dog. Similarly, many dog owners are wondering, “Can I purchase NexGard without a vet prescription?”

Of course, the recommended way to purchase is to get NexGard directly from your vet, as they can ensure that the medication is both stored and applied properly. However, if you’re having trouble getting a hold of your vet, you can easily order NexGard flea and tick pills from an online retailer or head over to a nearby PetSmart.

NexGard Reviews | NexGard Side Effects

While insecticides and acaricides may be effective at killing pests, how do you know if the afoxolaner in NexGard is safe to administer directly to your pet? One good way of evaluating whether NexGard is right for your dog is to consider the possible side effects.

According to the product website, common NexGard side effects include:

  • Vomiting
  • Itching
  • Diarrhea
  • Lethargy
  • Lack of appetite

Many NexGard flea and tick reviews also report dogs experiencing seizures after taking the flea and tick pill. As stated on the product packaging, NexGard should be used only under the guidance of a veterinarian and “with caution in dogs with a history of seizures.”

While the side effects listed above are somewhat standard for flea and tick medications, our NexGard review did find reports of additional, more serious NexGard side effects, detailed in the section below.

NexGard Reviews | Reported NexGard Problems & NexGard Safety Issues

When it comes to oral flea medication for dogs, the risk of negative side effects can be higher, as the pesticides and acaricides are distributed throughout the bloodstream.

Unfortunately, many flea and tick medications (like Bravecto) have come under intense criticism in the past few years, making thousands of pet owners second guess whether flea and tick medicine does more harm than good.

See below for an overview of reported NexGard problems that dog owners may want to consider before administering the NexGard flea and tick pill.

Adverse Drug Events (ADE) Reports

Pennsylvania veterinarian Elizabeth Carney runs Your Pets Need This, offering a strong opposition to various pesticide and acaricide-based flea medication, including NexGard.

What makes the website particularly compelling is that Carney has made significant efforts to obtain specific information on adverse NexGard side effects and reported NexGard problems, providing insight into the medication that NexGard does not readily offer to the general public.

Upon filing a Freedom of Information Act request, Carney received ADE reports for NexGard spanning 1/28/2017-5/2/2017. Within this time frame, there were 720 reported cases of side effects for dogs, with the most common including:

  • Vomiting (Reported 211 times)
  • Lethargy (Reported 132 times)
  • Severe itching (Reported 77 times)
  • Diarrhea (Reported 72 times)
  • Seizure (Reported 41 times)
  • Anorexia (Reported 40 times)
  • Panting (Reported 31 times)

Perhaps more unsettling are the 21 deaths which were reported in this time, including nine deaths by euthanasia. In fact, according to a second ADE report from 10/1/2017-12/31/2017, the total number of reported deaths had increased to 57, leading many to question NexGard’s safety.

It’s important to recognize that these are only reported side effects and deaths—because owners often do not officially report incidents, it’s likely that the actual number of serious side effects is higher.

Equally as important is to consider that ADE reports do not consider previously existing conditions, like a predisposition towards seizures, or possible complications with other medications used simultaneously.

NexGard Flea and Tick Reviews

Change.org Petition

A petition titled “Nexgard (flea & tick treatment) should be removed from the market WITHOUT DELAY!!!!” has earned nearly 6,000 signatures from both cautious dog owners and those who suspect that their dog’s death was connected to the NexGard flea and tick pill.

This petition is also rife with NexGard chewables reviews, providing a communal space for dog owners to share their stories and their reason for signing the petition. One such example comes from Sophie Munday, who says:

I signed this petition because this drug took the life of my beautiful Maltese Shih tzu who suffered horrific seizures! This needs to be banned!

Another personal NexGard review comes from Gemma Payne, who says:

This treatment has taken the life of my sister’s dog and many others, I cannot understand how it has been allowed onto the market in the first place nor why it is taking so long to have it removed after so many animals have lost their lives!

In her NexGard review, Pauline Gill points to a strong correlation between deaths and seizures among dogs who have taken NexGard, saying:

My daughter’s dog suffered seizures following use of Nexguard [sic] TWICE, only linking it to the drug on the second occasion. This second dose, heartbreakingly, resulted in her dog’s death. There appears to be a significant body of evidence showing that this was not an isolated case.

Closely connected to the petition is a Facebook group for members to share their stories about flea and tick treatments, including Simparica, Bravecto, and NexGard.

Interestingly, while NexGard may be part of the ongoing discussion, it’s worth mentioning that the largest number of reviews come from Bravecto and Simparica, rather than NexGard reviews. In fact, finding reports of dog deaths associated with NexGard problems seems to primarily be confined to NexGard reviews on petitions and blog postings, rather than social media or product listings.

Still, the continued association between NexGard and serious side effects may be enough for dog owners to approach the flea and tick pill with caution.

NexGard Reviews | What Do Pet Owners Say About NexGard?

If you are having trouble deciding whether NexGard is right for your dog, you may want to consider what other pet owners are saying about the product in their own NexGard reviews.

Surprisingly, NexGard reviews from popular consumer shopping sites paint a much different picture than personal reviews from petitions or blog posts. See below for an overview of what pet owners are saying about their experiences with the NexGard flea and tick pill. 

NexGard Reviews from 1-800-PetMeds

The largest number of NexGard flea and tick reviews comes from 1-800-PetMeds, with over 500 NexGard reviews and a total rating of 4.5 stars out of 5. With high ratings, the vast majority of these NexGard chewables reviews are positive, with pet owners praising the medicine for its ability to quickly and effectively kill fleas and ticks.

For example, in her NexGard review, user Brittany C says:

My beautiful dog is an Australian Shepherd and ever since she was about a year old til about 3 we always had trouble with giving her flea and tick liquid medicine on her back. She would foam at the mouth, shake horribly, and drool excessively.

When her vet recommended Nexguard [sic], I thought ok let’s give it a try. Immediately, my dog thought it was a treat! She loved it and had no reaction to it at all! Awesome product! Please give it a try to you loved doggies!!

User Jen603 offers a similar positive NexGard review, saying:

We live in a high tick population area. Nexgard makes all the difference- any ticks that DO make it onto my dogs, die quickly. Pricey, but worth it!

NexGard Reviews

In total, only 34 users on 1-800-PetMeds gave a negative NexGard review. Interestingly, these reviews primarily report that the product simply does not work, rather than cause serious side effects. Many pet parents state continuing to struggle with flea infestations even after administering three months’ worth of NexGard flea and tick medication.

For example, one user writes:

Have used topicals in the past with success, but they didn’t work this season. Tried Nexguard [sic] since it works beautifully on my mom’s dog. Not so for my Chorkie and Chihuahua. They had 2 weeks of peace and then were covered in fleas again. Returned to vet for a refund as too pricey to only work 14 days. Have not tried Comfortis, that will be next, I guess….

Another reviewer claims that the inefficiency of NexGard caused her dog to get Lyme disease, saying:

We have our springer spaniel on NexGard. We give this med faithfully every month. Our fur baby became very ill.  After x-rays, blood tests, [and] a stay at the hospital, it was determined she had Lyme disease. $900 for all the tests and meds! A disease that this med is supposed to prevent! Will never use again. If I could give it a 0 I would.

Conclusion: Is NexGard Safe to Use on Your Dog?

Regardless of the type of medication you choose, there will always be risks and side effects, as flea and tick products rely on various pesticides and acaricides to be effective.

Although NexGard flea and tick pills may be available over-the-counter at affordable prices, it’s important to consult with your veterinarian to gain a complete history of your dog’s health and potential risks before starting any pesticide-based medication.

Is NexGard safe? Can you trust that the NexGard ingredients will be effective on ticks, but gentle on your four-legged friend? As a pet owner, it can be difficult to tell, since NexGard reviews are significantly divided.

While many dog owners are having stress-free experiences, there are plenty of others who are having quite the opposite, prompting the question of whether there is an underlying NexGard safety issue.

In the case of our NexGard review, we cannot confidently recommend the use of NexGard without a vet prescription. In some cases—even with a full health history and recent examination—the adverse effects of NexGard have had severe consequences, posing a strong argument that NexGard is not as safe as advertised, earning an overall 2-star rating.

While the final decision ultimately rests in your hands, we strongly recommend discussing any questions or worries that you may have about any flea and tick medication with your veterinarian to ensure that your dog is happy, healthy, and pest-free.
