I left our brand new bottle of prozinc out of the frig for 11 hours. It was in the box but not refrigerated. I tried calling manufacture but it is after hours. My helpful vet said call the pharmacy. I now question why I go to this vet if they can't help me with this type of situation. Anyone else know what to do if Prozinc is left out this long. Still ok (safe) to use. Self life now that is has been left out? Our cat just got diagnosed about two months ago so I am new to all of this.
