Nizonide tablets contain nitazoxanide, an antiparasitic and antiviral medication primarily used to treat infections like diarrhea caused by Giardia and Cryptosporidium in humans. The nizonide is not typically recommended for pets without veterinary guidance. While some veterinarians may prescribe nitazoxanide for specific infections in animals, improper dosage can be harmful. If your pet has a parasitic infection, consult a veterinarian before considering Nizonide or any other medication. Using Nizonide without professional advice may lead to adverse effects. Always prioritize your pet’s safety by seeking expert guidance before administering any medication, including Nizonide.
