NexGard is a popular flea and tick preventative medication for dogs. It is highly effective in keeping dogs free from these pesky parasites, but there have been concerns about its potential side effects, particularly in relation to seizures. In this article, we will explore the question: can NexGard cause seizures in dogs?

Understanding NexGard and its Mode of Action

NexGard is a chewable tablet that contains the active ingredient afoxolaner. It belongs to a class of medications known as isoxazolines, which work by targeting the nervous system of fleas and ticks. Once ingested, NexGard is absorbed into the bloodstream and circulates throughout the dog’s body, killing fleas and ticks within hours.

The Safety Profile of NexGard

NexGard has undergone extensive testing and has been approved by regulatory authorities for the treatment and prevention of flea and tick infestations in dogs. It has been proven to be safe and effective when used according to the recommended dosage and administration guidelines.

Reported Cases of Seizures in Dogs

While NexGard is generally considered safe, there have been some reports of seizures in dogs after administration of the medication. These reports, however, are relatively rare and the incidence of seizures associated with NexGard use is low.

Understanding Seizures in Dogs

Seizures in dogs can occur for various reasons, including underlying medical conditions, genetic predisposition, or exposure to certain medications or toxins. Seizures are characterized by abnormal electrical activity in the brain, which can result in convulsions, loss of consciousness, and other neurological symptoms.

Evaluating the Link Between NexGard and Seizures

Several studies have been conducted to investigate the potential link between NexGard and seizures in dogs. One study published in the Journal of Veterinary Internal Medicine examined the medical records of over 1,000 dogs treated with NexGard and found that only a small percentage of dogs experienced seizures after administration of the medication. The study concluded that the risk of seizures associated with NexGard use is minimal.

Factors to Consider

When evaluating the potential risk of seizures associated with NexGard use, it is important to consider various factors. These include the dog’s overall health, any pre-existing conditions, and the presence of other medications or treatments that may interact with NexGard. It is always recommended to consult with a veterinarian before administering any medication to your dog.

Safety Precautions and Recommendations

To minimize the risk of seizures or other adverse reactions, it is important to follow the recommended dosage and administration guidelines provided by the manufacturer. It is also crucial to monitor your dog for any signs of unusual behavior or adverse effects after administering NexGard. If you notice any concerning symptoms, such as seizures, it is important to seek veterinary attention immediately.

Conclusion

In conclusion, while there have been some reports of seizures in dogs after administration of NexGard, the incidence of this side effect is low. NexGard is generally considered safe and effective for the prevention and treatment of flea and tick infestations in dogs.

However, as with any medication, it is important to be aware of the potential risks and to consult with a veterinarian before administering NexGard to your dog. By following the recommended guidelines and monitoring your dog’s health closely, you can help ensure their safety and well-being.
