Can Novox be used in dogs with immunodeficiency disorders?

Dogs with immunodeficiency disorders may have a weakened immune system, which can make them more susceptible to infections and other health problems. NSAIDs like Novox can also affect the immune system and increase the risk of certain side effects, such as gastrointestinal upset, liver or kidney dysfunction, and other adverse reactions. Therefore, it is recommended to use Novox with caution in dogs with immunodeficiency disorders and only under the guidance and supervision of a veterinarian.

Can Novox be used in dogs with viral infections?

Yes, but only in specific circumstances. However, there are a few safety measures that need to be followed while giving Novox to dogs who have viral illnesses. NSAIDs like Novox can suppress the immune system and raise the possibility of unpleasant side effects like stomach discomfort, liver or kidney damage, and other negative reactions. Additionally, immune systems that are already compromised in dogs with viral infections can make them more vulnerable to infections and other health issues. Novox should thus only be administered to dogs with viral infections with the advice and supervision of a veterinarian.
