Let's see...the only thing I have ever used is Derma-Vet Ointment. Just checked the ingredients and this is what's in it - "Nystatin-Neomycin Sulfate-Thiostrepton-Triamcinolone Acetonide". Hope I spelled all that right.
Don't know what is in Zymox, but don't think it's the same. Maybe by bumping this up, someone else will see this and respond
