As a pet owner, I've always been concerned about the safety of medications for my furry friends. I recently came across Nitrofurantoin, an antibiotic used to treat urinary tract infections in dogs and cats. While it seems to be effective in treating these infections, there have been some concerns regarding its safety. Side effects like vomiting, diarrhea, and loss of appetite have been reported, but these appear to be relatively rare. However, it's crucial to consult with your veterinarian before administering Nitrofurantoin to ensure it's appropriate and safe for your pet.
