compatibility

[3UNC]

i was told that if, for example, an antibiotic and D5 1/2 NS are running concurrently through a line (and you don't have any other access) and you need to give an IV push also (e,g morphine), you can stop the continuous infusions and give the push med, and as long as you flush the line with NS before and after admin of the push you aren't really worried about the drugs being compatible. my new-nurse mind didn't understand this when told by an experienced nurse. so with IV drug compatibility are you more so worried about two meds running concurrently that aren't compatible bc precipitate can form... the meds could crystallize? .. when exactly is incompatibility an issue with IV meds i guess is what i'm asking (.i'm aware of concurrent infusion of 2+ meds.. of course )

thanks!

always check with pharmacy or a drug reference. To me, incompatible means just that. I would find another option for the push med. Also, if the incompatibility is with the D5 you might check with MD/Pharmacy to see if NS could be used instead. If it is the antibiotic, you need another option.

Even though you flush there could still be residue in the line.

Consider that the push med could be given a different route or change the time.
