Thanks J for the reply. I have reconstituted some antibiotics for injecting animals and have kept the leftover for use over several days with not problems. So I figured the same would apply to the Caverject. However, as I said in my earlier post, the Pharmacist said the manufacture of the Caverject ...

Has anyone mixed a 40 mg vial of caverject and only used 20 mg and refrigerated/stored the remaining 20 mg for use later? I would like to get the 40 mg vials, use 20 mg and save the remaining 20 mg for later use. The manufacturer states to discard any unused amounts of the caverject.
