Droperidol IM use has re-emerged at my current site. Due to the heightened acuity during most if not all of the cases where droperidol IM administration is indicated, questions have been asked related to whether co-administered IM medications can be put into the same syringe as that of droperidol IM's.

Any data/literature/experience from you all would be greatly appreciated on trying to answer:

"Is droperidol IM injection syringe compatible with diphenhydramine hydrochloride IM injection?

And even more comprehensively:

"What is the current guidance on syringe/Y-site/IV compatibility for droperidol injection?"
