USP ⟨795⟩ Nonsterile Compounding: What's Required in 2026

If you work in a compounding pharmacy, or you're studying for the NAPLEX, PTCE, or a state board exam, you've probably heard that USP ⟨795⟩ was revised in 2023. What you may not realize is how many facilities, even ones that have been compounding for years, are still operating on outdated assumptions about what the standard actually requires.

This isn't about trying to trip anyone up. The revisions are genuinely better, more precise, more scientifically grounded, and more useful in practice than the old chapter was. But that only matters if people actually know what changed and why.

Here's a straight read of what ⟨795⟩ now requires, where facilities most commonly fall short, and what it all means for your exam prep or daily practice.

First: What Even Is USP ⟨795⟩?

USP ⟨795⟩ is the national quality standard for nonsterile compounding in the United States. It covers everything from how you source your ingredients, to how you train your staff, to how you assign a beyond-use date on a finished preparation. It became official on November 1, 2023, replacing a version of the chapter that had been in place since 2004.

The short version of what changed: the old chapter was vague in ways that caused real variation in practice. The new one is specific. It uses water activity instead of the old "water-containing vs. nonaqueous" categories. It names the Designated Person by role and spells out exactly what that person is responsible for. It gives you a five-step training sequence instead of a general suggestion to demonstrate competency.

Whether you're a pharmacist, a tech, a student, or someone whose job title never included the word "pharmacy" but you've somehow ended up compounding things, ⟨795⟩ applies to you if you're making CNSPs (compounded nonsterile preparations).

The Part That Trips People Up: Beyond-Use Dates

BUDs are the single most tested topic in ⟨795⟩ on board exams, and also one of the most misunderstood in practice.

The old system categorized preparations as "water-containing oral," "water-containing topical," or "nonaqueous." The new system uses water activity — the fraction of water that's actually free and available to support microbial growth, to classify preparations into aqueous (a _w ≥ 0.60) or nonaqueous (a _w < 0.60).

Here's the table you need to have cold:

A few things people consistently get wrong about this table:

• These are ceilings, not defaults. If any starting ingredient has an expiration date that falls before your calculated BUD, that ingredient's expiration date wins. Every time.
• You don't have to measure water activity yourself. The reference tables in ⟨795⟩ and the companion chapter ⟨1112⟩ tell you how to classify a preparation by dosage form. Your cream, your oral solution, your suppository — it's already been categorized for you.
• The 35-day BUD for preserved aqueous requires a preservative system. Not a preference. An actual antimicrobial preservative that holds up for the duration of the BUD. If you're relying on 35 days without one, you're outside the table limits.

Training: The Part That Gets Cited Most Often in Inspections

NABP inspectors have been reviewing compounding pharmacies against the revised ⟨795⟩ standards since they became official, and training documentation is where they find the most gaps.

The standard is clear: everyone who compounds, or who directly supervises compounding, has to demonstrate competency before working independently, and then again at least every 12 months. "Demonstrate" is doing real work in that sentence. The standard describes a five-step sequence: read and understand the requirements, observe demonstrations, practice with guidance, perform independently while being observed, and get signed off by the Designated Person.

The gap that shows up in inspections is usually one of two things: either the training happened but wasn't documented, or steps 4 and 5 were skipped. Someone watched a video and got handed a sign-off without ever being observed performing the actual skill.

A few specifics worth noting:

• Spill response training is required separately, and also has to happen every 12 months
• A one-person pharmacy still has to complete all of this — self-documentation is acceptable as long as it's thorough and retrievable
• Training records must be kept for at least two years and retrievable on request

The Designated Person: More Than Just a Name on a Form

Every compounding facility needs at least one formally designated person, named in your SOPs, not just acknowledged informally. What the DP is responsible for is specific:

• Setting up and overseeing the training program
• Selecting components and verifying sourcing
• Monitoring compounding in real time
• Corrective action when something goes wrong
• Annual review of the QA/QC program

The DP doesn't have to be a pharmacist, but the responsibilities are substantial. If there's a compliance gap at your facility, it will trace back to the DP, which means whoever holds that role needs to actually understand what ⟨795⟩ requires, not just sign off that they've read it.

What Inspectors Actually Check First

Based on real inspection data from NABP's Verified Pharmacy Program, here are the areas where compounding pharmacies are most likely to have documentation gaps:

Master Formulation Records and Compounding Records. A significant percentage of nonsterile pharmacies inspected since November 2023 have MFR or CR deficiencies. The most common issue isn't that the documents don't exist — it's that required elements are missing. A complete MFR needs the BUD reference source, expected appearance, QC acceptance criteria, and step-by-step instructions. A complete CR needs actual lot numbers and expiration dates for every component, who compounded and who verified, and a sign-off before the CNSP goes out.

Cleaning documentation. Cleaning logs have to be completed on every day compounding occurs, not weekly, not when you remember. Work surfaces get cleaned at the start and end of every shift, and between preparations using different ingredients. Storage shelving gets cleaned every three months at minimum. If your log shows a gap longer than that for shelving, you have a citable deficiency regardless of whether the shelves look clean.

Hand hygiene. Alcohol-based hand rub alone does not satisfy the ⟨795⟩ hand hygiene requirement. Soap and water for at least 30 seconds, dried with a disposable towel, before donning gloves. That's the sequence. This is a routine inspection observation point, and it comes up frequently.

Why This Matters for Your Exam

If you're studying for NAPLEX, PTCE, or MPJE, USP ⟨795⟩ content shows up consistently — usually framed as scenario questions about what the compounder should do next, or what's wrong with the described situation.

The concepts that show up most often:

• Whether a described activity is compounding or something else (reconstitution, administration, repackaging)
• Which BUD category applies and what the maximum days would be
• What "must" versus "should" language means in practice
• What the Designated Person is specifically responsible for
• The correct hand hygiene sequence and why hand rub alone isn't sufficient
• What a complete MFR and CR each need to contain

The ⟨795⟩ language is precise, and exam writers know it. Questions don't usually ask you to recall a fact — they ask you to apply the standard to a specific situation. That's only possible if you understand the reasoning behind the rules, not just the rules themselves.

A Practical Note on Implementation

If you're at a facility that's still working through implementation of the revised chapter, the most common advice from compliance consultants is to start with your SOPs and your training records. Those two areas, more than any others, determine whether you can demonstrate compliance when someone asks.

Your SOPs need to name the Designated Person, describe their responsibilities, cover all seven core training competency areas, and reflect the current minimum cleaning frequencies. Your training records need to show who was trained, on what, when, observed by whom, and that the DP signed off.

Everything else in ⟨795⟩ builds on those two foundations. If those are solid, the rest is manageable.
