For those new to the conversion, the difference
between the USP 797 and USP 800 is the general
protection of sterile compounds and spaces from
contamination. USP 800 expands controls for the
protection of workers and environments against
hazardous drug compounds. In contrast to USP 797,
which only remedies sterile compounding activities,
USP 800 takes a 360-degree approach for
processing hazardous drugs.
