Some deaths are blamed on this.
"According to the FDA, reported problems with Teva’s ketamine include lack of effect, prolonged effect and death. "
As a family member's 5 yr old dog died after an otherwise a routine dental in MO, unable to be totally revived, I am appalled that this has been going on for so long, and that so many brands are included in the general recall. I knew about the DVM pharmaceuticals problem, but didn't realize so many forms and brands were involved. These products are VERY hard to trace when the manufacturer is not on the label!
