Sections of the United States Pharmacopeia (USP) that don’t get enough attention are the General Notices. USP General Notices describe how the USP works. For example, this particular notice has shaped the applicability of USP 800:

“Applicable general chapters” means general chapters numbered below 1000 or above 2000 that are made applicable to an article through reference in General Notices, a monograph, or another applicable general chapter numbered below 1000.¹

Until recently, USP 800 was an official chapter within USP but wasn’t considered “compendially applicable” because it wasn’t referenced in the General Notices, a monograph or another applicable general chapter numbered below 1000. However, on November 1, 2023, revisions to USP Chapter 795 and Chapter 797 became official. USP 795 and 797 are applicable general chapters that reference USP 800, which make USP 800 compendially applicable and potentially enforceable.

To determine if USP 800 is enforceable in your practice, you need to know which state or states your pharmacy is licensed in and know the related state board of pharmacy requirements. In my review of state regulations, more than 30 states have language generally requiring compliance with USP when compounding. This general language would require compliance with USP 795, 797 and 800.

Alternatively, some states are not allowed to adopt items by reference in their regulations. In other words, some states cannot simply say, “Follow USP,” but are required to write their own regulations. Some of those states write regulations that closely mirror USP chapters, but those state regulations may differ from USP. A few states have requirements that are more stringent than USP 795, 797 and 800. Other states are still considering USP 800 and will make their decisions at some point in the future. Several states have also delayed enforcement of USP 795, 797 and 800 for one to two years.

A few resources may help you understand where your state board of pharmacy is on these topics, such as state board of pharmacy websites, newsletters and the “law book” of each state. Calling a state board of pharmacy or inspectors for information — notably with mixed results — may produce a productive result. Another resource available to members of the Alliance for Pharmacy Compounding (APC) is their Compilation of State-Adopted USP 795, 797 and 800 Rules. Please note that use of this resource requires APC membership.

If you’ve researched the potential enforcement of USP 800 where your pharmacy is licensed and found that it’s not currently being enforced, you may think that nothing needs to be done when compounding hazardous drugs. However, the FDA does.

The FDA releases its thoughts on a variety of topics through what they call guidance documents. The preface in the agency’s Guidance for Industry, Insanitary Conditions at Compounding Facilities states:

This guidance represents the current thinking of the Food and Drug Administration (FDA or the Agency) on this topic. It does not create any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. To discuss an alternative approach, contact the FDA office responsible for this guidance as listed on the title page.

The guidance initially says that it’s not binding on the FDA or the public — which might make you think it’s not important — to the contrary, that guidance is a critical resource for understanding FDA’s thoughts and expectations during the agency’s inspections of compounding facilities, independent of whether or not any particular USP chapters are enforced by the state board of pharmacy. The guidance specifically calls out the handling of hazardous drugs, including sensitizing or highly potent drugs:

Handling bulk drug substances or drug products that are hazardous, sensitizing, or highly potent (e.g., hormones) with inadequate controls to prevent cross-contamination. This includes:

• inadequate dedication, segregation, and containment (e.g., a powder-containment hood) of a suite, room, or piece of equipment based on risk;
• inadequate cleaning of rooms, work surfaces, and equipment (e.g., utensils), including spills;
• inadequate segregation of HVAC systems (as appropriate for the operation); and
• inadequate control over the movement of personnel and materials.

Other federal agencies, including the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH), are involved in protecting compounding pharmacy staff from potential exposure to hazardous drugs.

USP 800 may or may not be enforced by your board or boards of pharmacy, despite being an official chapter that is now compendially applicable within the USP. Regardless of a board of pharmacy’s position, the FDA, OSHA and NIOSH are interested in preventing the potential for cross-contamination of hazardous, sensitizing and highly potent drugs on patients and compounding pharmacy staff.

The FDA rarely, if ever, references a USP chapter in inspection reports for compounding pharmacies. The state’s position on USP 800 does not affect the FDA’s approach to preventing insanitary conditions from existing in compounding facilities. Nor does the state’s position affect OSHA regulations.

Members with clinical services access may contact our Clinical Services team for help with compounding sterile and nonsterile formulations in compliance with USP Chapters 795, 797, 800 and the FDA’s Insanitary Conditions Guidance, as well as other compounding concerns.
