FAQs on NexGard’s Efficacy Against Mites

1. Understanding NexGard: A Quick Overview

NexGard (afoxolaner) is an FDA-approved chewable tablet designed primarily to eliminate fleas and ticks. Over time, its efficacy in treating certain types of mite infestations has also come to light.


2. NexGard and Mites: The Battle Begins

Two main types of mites often affect dogs:

  • Sarcoptic Mites (Scabies): These mites burrow into the skin causing Sarcoptic mange, leading to severe itching and skin inflammation.
  • Demodex Mites: This mite lives in hair follicles, causing Demodectic mange, often seen in puppies and immunocompromised dogs.

NexGard effectively targets and kills these mites, reducing their numbers and eventually eliminating the infestation.


3. The Waiting Game: How Quickly Does NexGard Act?

Multiple studies and field experiences have provided insights:

  • Initial Reduction: Within the first 24 hours post-administration, NexGard begins its action. Owners may notice a reduction in their pet’s itchiness.
  • Significant Impact: By day 14, a significant reduction in mite populations can be expected. In some studies, mite counts dropped by over 97% within two weeks of the first dose.
  • Complete Elimination: Administering NexGard twice, one month apart, ensures near-total eradication of mites. By the end of the second month, most dogs show a 99.8% reduction in mite infestation.

4. Why NexGard’s Timeline Matters

Quick mite elimination is essential for several reasons:

  • Immediate Relief: Rapid action provides relief to the dog, reducing scratching, skin infections, and potential secondary complications.
  • Halting the Lifecycle: Mites have a life cycle of about 2-3 weeks. Rapid action disrupts their life cycle, preventing further reproduction.

5. Key Considerations When Using NexGard

Consult a Veterinarian: Always consult your vet before starting any treatment. Dosage and frequency should be tailored to the dog’s weight and specific needs.

Monitor for Side Effects: While NexGard is generally safe, some dogs might experience side effects such as vomiting, diarrhea, or lethargy. Any unusual behavior should be reported to the vet.

Environmental Clean-up: Alongside medication, ensure a clean environment. Wash dog bedding and keep the living space hygienic to prevent re-infestation.


6. In Conclusion

NexGard offers a rapid and effective solution for mite infestations in dogs. By understanding its mechanism and timeline, pet owners can make informed decisions to provide the best care for their furry companions. Always trust expert advice and stay informed to ensure a happy, itch-free life for your dog.


FAQs on NexGard’s Efficacy Against Mites


Q1: How does NexGard actually work to kill mites?

Q8: My dog has had mites before. Can NexGard be used as a preventative measure?

Answer: NexGard primarily acts as a treatment. However, its monthly administration can also serve as a preventative measure against future mite infestations, given its ability to disrupt the mite life cycle.


Q9: Can environmental factors influence NexGard’s efficacy?

Answer: Environmental cleanliness is crucial. While NexGard targets mites on the dog, mites in the dog’s environment could lead to re-infestation. Regular cleaning of bedding, toys, and living spaces complements NexGard’s action.


Q10: How should NexGard be stored?

Answer: Store NexGard in its original packaging, away from moisture and direct sunlight, at room temperature. Keep it out of reach of children and pets to avoid accidental ingestion.


Q11: Is NexGard effective against all types of mites?

Answer: NexGard is primarily used against sarcoptic mange mites (Sarcoptes scabiei). Its efficacy against other types of mites, such as Demodex or ear mites, may vary. Always consult your veterinarian for specific mite infestations.


Q12: If I miss a dose, how soon should I give NexGard to my dog?

Answer: Administer NexGard as soon as you remember. It’s essential to maintain monthly intervals for optimal efficacy. If you’ve missed a dose by a few weeks, discuss a revised schedule with your veterinarian.


Q13: Can I bathe my dog after administering NexGard?
