USP 797 compliance ensures patient safety during sterile compounding. If you work in a pharmacy, hospital, or cleanroom environment, following USP 797 guidelines protects both patients and staff.
This article breaks down compliance into five clear steps. We explain what USP 797 is, how it works, and what you must do to meet its strict standards. Learn the basics of cleanroom design, risk levels, and sterile preparation. We also cover how to prevent errors using best practices like gloved fingertip testing and media-fill testing procedures.
What Does USP 797 Stand For? (Definition & History)
USP 797 refers to Chapter 797 of the United States Pharmacopeia, which defines sterile compounding requirements. It was first introduced in 2004 and has since evolved to ensure higher safety and quality in pharmacies. The term “USP 797” specifically targets compounded sterile preparations (CSPs), setting cleanroom design standards and aseptic processing procedures. These standards apply across all facilities involved in sterile medication production.
The chapter establishes guidelines for beyond-use dating, environmental monitoring protocols, and personnel training. It also sets benchmarks for sterility assurance levels and compounding quality assurance. To remain compliant, professionals must understand media-fill testing procedures, gloved fingertip tests, and ISO classifications. The latest USP 797 updates and revisions reflect a focus on minimizing contamination and patient risk.

How Does USP 797 Work? (Step-by-Step Procedure)
USP 797 compliance starts with designing and maintaining the proper cleanroom environment. This includes meeting ISO class 5 cleanroom requirements, using primary engineering controls like laminar airflow workbenches, and secondary engineering controls such as buffer rooms and ante areas. Each area must follow specific airflow, particle count, and pressure requirements.
Next, staff must undergo compounding personnel training. This includes proper gowning, aseptic technique step-by-step guides, and ongoing evaluations. Regular gloved fingertip testing and media-fill testing procedures help verify competency. Monitoring includes environmental sampling and beyond-use date determination for CSPs. Cleanroom standards must be maintained at all times to avoid contamination and maintain compliance.

Why Is USP 797 Compliance So Important?
Patient Safety Comes First
Patient safety depends on sterile compounding standards. These seven reasons highlight why USP 797 compliance is critical:
Prevent contamination – One mistake can lead to microbial contamination and serious infections.
Protect patient health – A single error can cause life-threatening complications.
Follow proven guidelines – USP 797 guidelines reduce risks through detailed requirements.
Ensure sterile environments – Cleanroom design standards keep CSPs safe during preparation.
Enforce best practices – Aseptic processing procedures reduce risk during every step.
Maintain consistent safety – Following procedures ensures quality across all batches.
Deliver safe medications – Pharmacies can confidently provide compounded sterile preparations.
Legal and Regulatory Requirements
Compliance also protects your pharmacy or facility from legal action. These seven factors explain why regulatory readiness is essential:
Avoid penalties – Failing to comply can lead to costly fines or license suspension.
Stay audit-ready – Regulators check for complete documentation and proper procedures.
Meet sterility standards – Agencies require strict adherence to sterility assurance levels.
Pass testing evaluations – Media-fill testing procedures confirm your aseptic technique.
Prove staff competency – Gloved fingertip test results demonstrate qualified personnel.
Maintain credibility – Compliant facilities protect their reputation and patient trust.
Follow pharmacy law – USP 797 compliance for pharmacies is a regulatory expectation.
Essential USP 797 Compliance Areas
Sterile compounding requirements
These define the standards and procedures for preparing compounded sterile preparations (CSPs). They ensure all preparations meet sterility assurance levels and reduce contamination risks.
Cleanroom design standards
These standards guide how to design and maintain ISO-classified environments. They control particle count, airflow, and room pressure to preserve sterile conditions.
Aseptic processing procedures
These procedures outline step-by-step methods for handling sterile drugs. They support safe compounding by eliminating the risk of microbial contamination.
Beyond-use date determination
This process uses validated data to assign expiration periods. It ensures compounded medications remain effective and safe until use.
Environmental monitoring protocols
These protocols require routine sampling of air and surfaces. They detect microbial or particulate contamination early to prevent quality issues.
Compounding documentation requirements
Accurate documentation tracks each compounding step. It supports audits, quality reviews, and traceability in case of adverse events. Define procedures for safe preparation of CSPs.
How Do Facilities Achieve and Maintain USP 797 Compliance?
Facility Setup and Validation
First, design your space based on ISO class 5 requirements. Install primary engineering controls like laminar airflow workbenches. Use secondary engineering controls to create clean zones.
Validate airflow, pressure, and cleanliness with certified testing. Then, review compounding risk categories to classify your preparations correctly.
Ongoing Monitoring and Training
Continue environmental monitoring in compounding pharmacies daily. Schedule gloved fingertip sampling and media-fill tests monthly. Run sterile compounding training programs quarterly.
Keep staff updated on aseptic technique best practices. Maintain full documentation for audits. Monitor trends to identify quality assurance gaps before they become problems.
Best Practices for Ongoing USP 797 Compliance
Limit contamination with proper handling. These isolators protect both the sterile product and the operator. Use validated cleaning and disinfection routines inside the isolator. Always follow gloving and transfer protocols to maintain the sterile boundary.
Control pressure and airflow between clean zones. Maintain separation of classified spaces to reduce contamination. Validate room pressure differentials using calibrated equipment. Use pressure gauges and alarms to monitor real-time airflow conditions.
Simulate real compounding under stress conditions. Evaluate aseptic skills through mock procedures using growth media. Monitor samples for microbial contamination. Document findings and retrain staff if results show deviation.
USP 797 Compliance Requirements You Can’t Skip
- Gloved fingertip test – Confirms hand hygiene and gowning effectiveness.
- Media-fill test – Validates aseptic processing procedures.
- ISO classifications – Set particle count and air quality benchmarks.
