Introduction: Understanding FDA Approval for Pet Medications
The health and well-being of our beloved canine companions are paramount, and choosing the right medications to protect them from parasites like fleas and ticks is a significant decision. The U.S. Food and Drug Administration (FDA) plays a crucial role in ensuring the safety and efficacy of these veterinary drugs.

Read on to discover the definitive answer and learn everything you need to know.
The FDA Approval Process for Veterinary Drugs
The FDA’s Center for Veterinary Medicine (CVM) is responsible for regulating animal drugs, including parasiticides like NexGard. The approval process is a rigorous one, designed to protect animal health. It involves several key stages:
- Pre-Clinical Research: Extensive laboratory testing to evaluate the drug’s safety and efficacy.
- Clinical Trials: Field studies conducted in target animals (dogs, in the case of NexGard) to assess the drug’s performance under real-world conditions.
- Data Review: The FDA thoroughly evaluates the data from pre-clinical research and clinical trials to determine if the drug is safe and effective.
- Manufacturing Inspection: The FDA inspects the manufacturing facilities to ensure that the drug is produced according to strict quality standards.
- Post-Market Surveillance: Ongoing monitoring of the drug’s safety and efficacy after it has been approved and is available on the market.
Benefits of NexGard: Flea and Tick Protection
NexGard (afoxolaner) offers several benefits as a flea and tick preventative for dogs:
- Broad-Spectrum Protection: Effective against various flea and tick species.
- Monthly Dosage: Convenient administration with a chewable tablet given once a month.
- Systemic Action: Works internally, killing fleas and ticks after they bite. This helps reduce the risk of disease transmission.
- Safe for Many Dogs: Generally well-tolerated by most dogs, including those with certain sensitivities.
Potential Side Effects and Considerations
While NexGard is generally safe, it’s essential to be aware of potential side effects. Some dogs may experience:
- Vomiting
- Diarrhea
- Lethargy
- Loss of Appetite
- Seizures (in rare cases; see further discussion in the FAQs)
It’s crucial to consult with your veterinarian before starting your dog on NexGard, especially if your dog has a history of seizures or other neurological conditions. They can assess your dog’s individual risk factors and determine if NexGard is the right choice.
Understanding Afoxolaner and Its Mechanism of Action
The active ingredient in NexGard, afoxolaner, belongs to the isoxazoline class of parasiticides. It works by interfering with the nervous system of fleas and ticks, causing paralysis and death. Afoxolaner is absorbed into the dog’s bloodstream after the tablet is ingested. When fleas and ticks bite the dog, they are exposed to afoxolaner and are killed. This systemic action ensures comprehensive protection throughout the month.
Common Mistakes When Using NexGard
To ensure NexGard is used safely and effectively, avoid these common mistakes:
- Skipping Doses: Consistent monthly administration is crucial for continuous protection.
- Incorrect Dosage: Always administer the correct dosage based on your dog’s weight.
- Giving to Cats: NexGard is specifically formulated for dogs and should not be given to cats.
- Ignoring Potential Side Effects: Monitor your dog for any adverse reactions and consult your veterinarian immediately if you notice any concerning symptoms.
- Not Consulting a Veterinarian: Always consult with your veterinarian before starting any new medication, including NexGard.
Dosage and Administration Guidelines
NexGard is available in various dosages, tailored to different weight ranges of dogs. It’s crucial to select the appropriate dosage based on your dog’s current weight. The chewable tablets are palatable, making administration easy for most dogs. Simply offer the tablet as a treat, or mix it with your dog’s food. Always ensure your dog consumes the entire tablet.
Conclusion: Trusting FDA-Approved Medications
Protecting your dog from fleas and ticks is essential for their health and well-being. The FDA approval process provides assurance that medications like NexGard have undergone rigorous testing and meet strict safety and efficacy standards. By understanding the benefits, potential side effects, and proper usage of NexGard, and by consulting with your veterinarian, you can make informed decisions about your dog’s parasite prevention strategy. Remembering that Is NexGard approved by the FDA? The answer is yes, and this approval represents a commitment to quality and safety.
