Drug Precipitation

When you work in IV you learn that certain drugs shouldn’t be combined back to back as they “precipitate.” In my mind I understood that to be bad but never saw what would happen. Well it happened today!

I mistakenly used a syringe that had just been used to draw up papaverine to also draw up heparin…..watching this cloudy liquid fill the syringe and a worm-like substance form in the center was pretty fun party trick!

Not a great Pic below, but it was really hard to focus.
