When it comes to keeping our furry companions safe from pesky fleas and ticks, many of us reach for trusted solutions like NexGard. It's a common choice, and for good reason – it's effective. But like any medication, it's wise to have a clear picture of what to expect, including any potential side effects.
NexGard, and its related product NexGard PLUS, are oral chewable tablets designed to tackle external parasites like fleas and four common types of ticks. For puppies and dogs eight weeks and older, weighing over four pounds, these can be a real lifesaver in preventing infestations. Interestingly, veterinarians sometimes use NexGard off-label for other skin conditions like demodectic mange, sarcoptic mange, and ear mites, though this is always a decision made in consultation with your vet.
So, what about those side effects? The active ingredient, afoxolaner, works by over-exciting the nervous systems of fleas and ticks, leading to their demise. While generally well-tolerated, some dogs might experience adverse reactions. The most commonly reported side effects, as noted in safety studies, tend to be gastrointestinal. This can include vomiting or diarrhea. Some dogs might also show signs of decreased appetite or lethargy.
It's important to note that NexGard PLUS contains additional ingredients to combat heartworms and internal parasites like hookworms and roundworms. While the core active ingredient for fleas and ticks is the same, the broader spectrum of action means it's always crucial to use the specific product your veterinarian recommends for your dog's needs.
One area where caution is particularly advised is in dogs with a history of seizures or other neurological disorders. The way these medications affect the nervous system means that for these sensitive pups, there's a higher potential for adverse neurological events. If your dog has a pre-existing neurological condition, a thorough discussion with your veterinarian about the risks and benefits is absolutely essential.
Beyond these, there are a few other considerations. Safety studies haven't been extensively performed on breeding, pregnant, or nursing dogs. So, if your dog falls into one of these categories, your vet will need to carefully weigh the pros and cons.
What should you do if you notice something unusual after giving your dog NexGard? The first and most important step is to contact your veterinarian. They are your best resource for understanding whether what you're seeing is a common, mild side effect, or something more serious that requires immediate attention. They can also advise on how to manage any mild symptoms or discuss alternative treatment options if necessary.
Ultimately, NexGard is a valuable tool in parasite prevention, but like all medications, it's about informed use. Understanding the potential side effects, discussing your dog's specific health history with your vet, and being observant after administration are key to ensuring your dog stays happy and healthy.
