Nexgard is an oral medication administered to canines for the prevention and treatment of flea and tick infestations. Its active ingredient, afoxolaner, targets the nervous systems of fleas and ticks after they ingest it through the dog’s blood. The time required for the medication to become fully effective is a crucial consideration for pet owners.
Prompt and effective control of parasites is vital for canine health. Flea infestations can lead to allergic dermatitis, anemia, and tapeworm transmission. Ticks, on the other hand, can transmit serious diseases such as Lyme disease, ehrlichiosis, and Rocky Mountain spotted fever. The rapid onset of action provided by such medications minimizes the risk of these health complications and improves the animal’s overall well-being. Historically, parasite control relied on topical treatments, which could be messy and less effective due to varying application techniques and wash-off.
