NexGard, a popular oral flea and tick prevention medication for dogs, has garnered much attention in the pet care realm. Yet, many pet owners often wonder, “How quickly does NexGard start working?”
NexGard: An Overview
Before delving into the specifics of NexGard’s action, it’s vital to provide a brief overview of the medication itself. NexGard is a chewable tablet prescribed by veterinarians, primarily used to treat and prevent flea infestations and treat and control ticks in dogs. The active ingredient, afoxolaner, attacks the nervous system of these parasites, causing their eventual death.
The Onset of Action: How Quickly Does NexGard Start Working?
Now, to the question at hand: how quickly does NexGard begin working? After administration, NexGard begins to kill fleas within four hours, according to the manufacturer. As for ticks, NexGard can effectively eliminate them within 48 hours, providing a considerable level of control over these pests.
However, it’s essential to remember that NexGard does not repel ticks or fleas. The parasites must first bite and ingest the afoxolaner in the dog’s bloodstream before the product begins to take effect.
NexGard’s Peak Efficacy: When Can You Expect Maximum Results?
While NexGard starts to work relatively quickly after ingestion, it reaches peak effectiveness within 24 hours for fleas and 48 hours for ticks. Thus, you can expect NexGard to offer maximum protection within two days of administration.
Furthermore, NexGard remains effective for 30 days post-administration, making it an excellent option for monthly preventative care for your furry companion.
The Lifespan of Ticks and Fleas with NexGard
NexGard disrupts the lifecycle of fleas and ticks. It kills adult fleas before they can lay eggs, thereby preventing future infestations. The product also kills ticks before they can transmit diseases, given that transmission generally requires more than an hour of blood feeding.
Concluding Remarks: NexGard’s Reliable Effectiveness
Understanding the speed of NexGard’s action provides peace of mind for pet owners navigating the world of flea and tick prevention. Though it doesn’t repel these parasites, NexGard quickly and effectively eliminates them once they’ve bitten your pet, offering a robust line of defense against infestations and related diseases.
