thanks guys! unfortunately I have seen incompatible meds hung together a couple times, meds that could cause precipitation when combined. Incident reports were done both times, and the patients were ok luckily. I was just curious what happens to the precipitation, just curious if it did dissolve eventually (I know worse can happen). One of the times the med was hung via Y-site and a pharmacist told me b/c the two meds were not in contact for very long this may have not given the medication enough time to form precipitate. Thanks for ur time!
