Oxytet is a failure in pinkeye here too....maybe not a complete failure, but requires multiple treatments plus some get a severe case and it doesn't seem to work quickly enough.

Problem with using Draxxin is now that it's labeled for pinkeye and footrot as well as respiratory disease, it will quickly lose effectiveness (due to resistant pathogens). One of my vets says there is already some Draxxin resistance seen in respiratory disease organisms.

Draxxin will be the next Roundup.
