Lactated ringers and zosyn compatibility?

Published

I was having this discussion with someone earlier. I was told that only new reformulated zosyn is compatible with lactated ringers solution at y site. What do they mean by "reformulated" and just how common are these reformulated versions of zosyn? Does anyone hang zosyn with LR? I am always hanging zosyn on my unit and want to be sure.

It is compatible with LR if it contains EDTA. Best bet is for you to consult with your pharmacist with any compatibility questions, document who you spoke with and what the response was.

Definitely confer with your pharmacist who knows the most about your particular medications and formulations.

I second (third?) the advice to contact your pharmacist. For example, heparin and dilt are listed on Micromedex as "variable." My facility uses a preparation of both where they are compatible. Obviously some combinations are not compatible.

Much like that example, you should talk to a pharmacist about the compatibility of the Zosyn preparation in your facility.
