Negative Pressure Rooms Required in Low Volume Hazardous Compounding Rooms

* RJLG Question 8: We are a small home infusion pharmacy. Approximately 2% of our patient base receives chemotherapy medications (primarily 5FU). Do we need a negative pressure room if: we compound/mix in a BSC, maintain a “safety zone” around the BSC within the clean room and utilize the PhaSeal product line when compounding?

* RJLG Answer 8: The Hazardous Drugs as CSPs section of USP797 allows low volume hazardous drug compounding in a non-negative pressure buffer or clean room if two tiers of containment are used, e.g., using a closed-system transfer device (CSTD) within a biological safety cabinet (BSC) or compounding aseptic containment isolator (CACI). This is not an exemption from training and personal protective equipment (PPE) requirements, or recommended environmental sampling.
