Nexgard: What is it Used For?

Are you a pet owner and curious about Nexgard? You've come to the right place! This article dives deep into what Nexgard is, what it's used for, how it works, and everything else you need to know to keep your furry friend healthy and happy. Let's get started!

What is Nexgard?

Nexgard is a popular brand of chewable tablets designed to protect dogs from fleas and ticks. These parasites can cause significant discomfort, skin irritation, and even transmit diseases to our beloved pets. Nexgard offers a convenient and effective way to prevent and treat these infestations, ensuring your dog remains comfortable and healthy. The active ingredient in Nexgard is afoxolaner, an insecticide and acaricide that belongs to the isoxazoline class of compounds. Afoxolaner works by interfering with the nervous system of fleas and ticks, leading to their paralysis and death. What sets Nexgard apart from other flea and tick treatments is its oral administration, which many pet owners find more convenient than topical applications. Oral medications like Nexgard also eliminate the risk of residue transferring onto furniture, children, or other pets.

One of the standout features of Nexgard is its ease of use. The chewable tablet is palatable to most dogs, making administration a breeze. Unlike topical treatments that require careful application and drying time, Nexgard can be given with or without food, providing flexibility for pet owners. The convenience and effectiveness of Nexgard have made it a popular choice among veterinarians and dog owners alike, ensuring that dogs receive the protection they need in a hassle-free manner. Additionally, Nexgard offers a month-long protection with a single dose, simplifying the parasite control routine for busy pet parents. The consistent protection afforded by Nexgard helps to break the flea life cycle, preventing re-infestation and maintaining a healthy environment for your dog.

Moreover, the safety profile of Nexgard is well-established, making it a reliable option for a wide range of dogs. Clinical trials have demonstrated that Nexgard is safe for use in puppies as young as 8 weeks old and weighing at least 4 pounds. However, it's always best to consult with your veterinarian before starting any new medication, especially for dogs with pre-existing health conditions or those taking other medications. Overall, Nexgard represents a significant advancement in parasite control, offering a convenient, effective, and safe solution for protecting dogs from fleas and ticks. With its palatable chewable form and month-long protection, Nexgard simplifies the process of keeping your furry friend healthy and happy.

What is Nexgard Used For?

Nexgard is primarily used for the prevention and treatment of flea and tick infestations in dogs. Let's break down the specific uses:

  • Flea Control: Nexgard is highly effective in killing adult fleas. It starts working within hours of administration and provides month-long protection. This helps to alleviate flea-related symptoms like itching, scratching, and skin irritation. By eliminating fleas, Nexgard also reduces the risk of flea allergy dermatitis (FAD), a common allergic reaction in dogs caused by flea bites. A single dose of Nexgard can effectively eliminate existing flea infestations and prevent re-infestation for a full month. The rapid action of afoxolaner ensures that fleas are quickly eradicated, providing relief to your dog and preventing further discomfort. Furthermore, Nexgard helps to break the flea life cycle by killing adult fleas before they can lay eggs, reducing the overall flea population in the environment. This comprehensive flea control helps to maintain a healthy and comfortable living space for both pets and their owners.

  • Tick Control: Nexgard is also effective against several common tick species, including black-legged ticks (deer ticks), American dog ticks, brown dog ticks, and Gulf Coast ticks. These ticks can transmit diseases like Lyme disease, ehrlichiosis, and Rocky Mountain spotted fever. By killing ticks, Nexgard helps to prevent these potentially serious illnesses. The ability of Nexgard to control multiple tick species makes it a valuable tool in protecting dogs from a wide range of tick-borne diseases. Regular use of Nexgard can significantly reduce the risk of tick infestations and the associated health risks. The active ingredient, afoxolaner, ensures that ticks are eliminated quickly and effectively, minimizing the chances of disease transmission. Furthermore, Nexgard's month-long protection provides continuous defense against ticks, even in areas with high tick populations.

  • Treatment of Flea Allergy Dermatitis (FAD): In dogs with FAD, even a single flea bite can trigger an intense allergic reaction. Nexgard helps to control flea populations, reducing the likelihood of flea bites and minimizing the symptoms of FAD. By providing rapid and effective flea control, Nexgard helps to break the cycle of allergic reactions and improve the overall quality of life for dogs suffering from FAD. Regular use of Nexgard can significantly reduce the severity and frequency of FAD flare-ups, allowing dogs to live more comfortably. The elimination of fleas also reduces the need for additional treatments, such as corticosteroids or antihistamines, which can have potential side effects. With consistent use, Nexgard can help to manage FAD and maintain healthy skin in affected dogs.

How Does Nexgard Work?

Nexgard contains the active ingredient afoxolaner, which is an insecticide and acaricide. Afoxolaner works by targeting the nervous system of fleas and ticks. Here's a more detailed look:

  • Mechanism of Action: Afoxolaner blocks the gamma-aminobutyric acid (GABA)-gated chloride channels in the nervous system of fleas and ticks. GABA is a neurotransmitter that inhibits nerve impulses. By blocking these channels, afoxolaner disrupts the normal nerve function, leading to uncontrolled nerve activity. This disruption causes paralysis and death of the fleas and ticks. The selective action of afoxolaner on the nervous systems of insects and arachnids, with minimal impact on mammals, makes it a safe and effective option for parasite control in dogs. The compound is readily absorbed into the bloodstream, allowing it to reach fleas and ticks quickly after administration. This rapid action ensures that parasites are eliminated before they can cause significant harm or transmit diseases.

  • Absorption and Distribution: After a dog takes Nexgard, afoxolaner is rapidly absorbed into the bloodstream. It reaches peak concentrations within a few hours. The drug is then distributed throughout the body, including the skin, where fleas and ticks are likely to be found. The systemic distribution of afoxolaner ensures that it reaches all areas of the dog's body, providing comprehensive protection against fleas and ticks. This is particularly important for dogs with dense fur or those that spend a lot of time outdoors, where they are more likely to encounter parasites. The consistent levels of afoxolaner in the bloodstream provide continuous protection for a full month, simplifying the parasite control routine for pet owners.

  • Elimination: Afoxolaner is slowly eliminated from the body over the course of a month. This provides sustained protection against fleas and ticks. The slow elimination rate ensures that the drug remains effective for the entire month, providing continuous defense against parasite infestations. The gradual decline in afoxolaner levels means that a single dose of Nexgard is sufficient to maintain protection throughout the month. This convenient dosing schedule makes it easy for pet owners to keep their dogs protected from fleas and ticks without the need for frequent applications or treatments. The long-lasting effect of afoxolaner also helps to prevent re-infestation, maintaining a healthy environment for dogs and their owners.

Dosage and Administration

Nexgard is available in different strengths, depending on the dog's weight. It's crucial to use the correct dosage to ensure effectiveness and safety. Always follow your veterinarian's instructions and read the product label carefully. Here are some general guidelines:

  • Weight Ranges: Nexgard is typically available in several dosage strengths to accommodate different weight ranges of dogs. Common weight ranges include 4-10 pounds, 10.1-24 pounds, 24.1-60 pounds, and 60.1-120 pounds. It is essential to choose the correct dosage based on your dog's current weight to ensure optimal efficacy and safety. Regularly weigh your dog to ensure that you are using the appropriate dosage, especially as they grow or experience weight fluctuations. Using the wrong dosage can lead to ineffective treatment or potential adverse effects.

  • Administration: Nexgard is a chewable tablet that can be given with or without food. Most dogs readily accept the chewable tablet due to its palatable flavor. If your dog is a picky eater, you can try hiding the tablet in a small piece of food to encourage them to take it. The convenience of oral administration makes Nexgard an easy and stress-free option for pet owners. Unlike topical treatments that require careful application and drying time, Nexgard can be given quickly and easily. This is particularly helpful for dogs that are difficult to handle or those that dislike topical medications. The palatable flavor of the chewable tablet also eliminates the need for force-feeding or other stressful administration methods.

  • Frequency: Nexgard is administered once a month. Consistent monthly administration is essential for maintaining continuous protection against fleas and ticks. Marking your calendar or setting a reminder can help you remember to give your dog their monthly dose of Nexgard. The consistent use of Nexgard helps to break the flea life cycle and prevent re-infestation. By maintaining continuous protection, you can ensure that your dog remains comfortable and healthy throughout the year. Regular monthly administration also simplifies the parasite control routine, making it easier for pet owners to stay on top of their dog's health.

Potential Side Effects

Like all medications, Nexgard can cause side effects in some dogs. However, side effects are generally mild and uncommon. The most frequently reported side effects include:

  • Vomiting: Some dogs may experience vomiting after taking Nexgard, especially when first starting the medication. If vomiting occurs, it is usually mild and resolves on its own. To minimize the risk of vomiting, try giving Nexgard with a small meal or snack. If vomiting persists or becomes severe, consult with your veterinarian. In most cases, vomiting is a temporary side effect that does not require additional treatment. However, it is important to monitor your dog closely and seek veterinary advice if you have any concerns.

  • Dry or Flaky Skin: In rare cases, dogs may develop dry or flaky skin while taking Nexgard. This side effect is typically mild and can be managed with gentle grooming and moisturizing shampoos. Ensuring that your dog is properly hydrated and receiving a balanced diet can also help to maintain healthy skin. If the skin condition worsens or becomes uncomfortable for your dog, consult with your veterinarian. In some cases, a change in diet or the use of a medicated shampoo may be recommended.

  • Lethargy: Some dogs may appear tired or lethargic after taking Nexgard. This side effect is usually temporary and resolves within a day or two. Ensure that your dog has a quiet and comfortable place to rest and monitor them for any other signs of illness. If lethargy persists or is accompanied by other symptoms, such as loss of appetite or fever, contact your veterinarian. In most cases, lethargy is a mild and self-limiting side effect that does not require specific treatment.

  • Other rare side effects: include diarrhea, decreased appetite, or seizures. Seizures have been reported very rarely, primarily in dogs with a history of seizures. If you notice any unusual behavior or signs of illness after giving your dog Nexgard, contact your veterinarian immediately.

It's important to note that the benefits of using Nexgard to protect your dog from fleas and ticks generally outweigh the risk of side effects. However, if you have any concerns, it's always best to consult with your veterinarian.

Precautions

Before using Nexgard, consider the following precautions:

  • Veterinary Consultation: Always consult with your veterinarian before starting your dog on Nexgard. Your veterinarian can assess your dog's overall health and determine if Nexgard is the right choice for them. They can also advise you on the correct dosage and administration based on your dog's weight and medical history. Veterinary consultation is particularly important for dogs with pre-existing health conditions or those taking other medications. Your veterinarian can help you to identify any potential risks or interactions and ensure that Nexgard is used safely and effectively.

  • Medical History: Inform your veterinarian about your dog's complete medical history, including any allergies, pre-existing conditions, or medications they are currently taking. This information is crucial for determining the safety and suitability of Nexgard. Certain medical conditions, such as a history of seizures, may increase the risk of adverse reactions to Nexgard. Similarly, certain medications may interact with afoxolaner, the active ingredient in Nexgard. Providing your veterinarian with a complete medical history will help them to make informed decisions about your dog's care and minimize the risk of potential complications.

  • Puppies: Nexgard is safe for use in puppies 8 weeks of age or older and weighing at least 4 pounds. However, it's always best to consult with your veterinarian before giving any medication to a young puppy. Puppies are more susceptible to the effects of medications, and careful monitoring is essential. Your veterinarian can assess your puppy's overall health and development and determine if Nexgard is appropriate for them. They can also advise you on the correct dosage and administration to ensure the safety and well-being of your puppy.

Conclusion

Nexgard is a reliable and convenient option for protecting your dog from fleas and ticks. Its ease of use, month-long protection, and proven effectiveness make it a popular choice among pet owners. Always consult with your veterinarian to determine if Nexgard is the right choice for your furry friend and to ensure proper dosage and administration. With the right approach, you can keep your dog happy, healthy, and free from bothersome parasites.
