What USP 795, 797, and 800 actually mean for you

If you have ever been handed a medication that was mixed just for you, you have used a compounded medication. Compounding is when a pharmacy makes a medication from scratch instead of taking it ready-made off a shelf. It is how we can leave out a dye you react to, turn a pill into a liquid for a child, or mix a cream at a strength your doctor wants but a factory does not make.

Because a person is making that medication by hand, quality has to be controlled carefully. That is the job of three sets of rules with plain numbers for names: USP 795, USP 797, and USP 800. USP stands for the United States Pharmacopeia, the group that writes the national standards pharmacies are expected to follow. Here is what each one actually covers, in plain language.

USP 795: non-sterile compounding

Non-sterile means the medication does not have to be completely germ-free, because of how it goes into your body. Think of creams, ointments, capsules, and many liquids you take by mouth or put on your skin. USP 795 sets the rules for making these safely. It covers things like clean work areas, accurate measuring, correct ingredients, proper labeling, and how long a compound is safe to use before it should be thrown out (the beyond-use date). It is the baseline standard most everyday compounds follow.

USP 797: sterile compounding

Sterile means germ-free. Some medications go straight into your bloodstream, your eye, or another place where even a tiny bit of contamination could cause real harm. Examples are injections, IV bags, and eye drops. USP 797 sets much stricter rules for making these. It covers special clean rooms with filtered air, testing the air and surfaces for germs, extra training and gowning for the person compounding, and tighter limits on how long a sterile compound can be kept. Sterile compounding is harder and more tightly controlled than non-sterile, and not every pharmacy does it.

USP 800: hazardous drugs

Some medications are powerful enough that they can be dangerous to the people handling them, not just to a patient who takes the wrong dose. Certain chemotherapy and hormone drugs are common examples. USP 800 sets the rules for handling these hazardous drugs safely, from the moment they arrive to the moment they are thrown away. It covers special ventilation, protective equipment for staff, separate storage, and careful cleanup, so that workers, other patients, and the medication itself all stay safe. USP 800 works alongside 795 and 797, not instead of them.

What PCAB accreditation signals

PCAB stands for the Pharmacy Compounding Accreditation Board. It is run by an independent group (ACHC) that inspects compounding pharmacies and checks whether they truly meet the USP standards above. When a pharmacy earns PCAB accreditation, it means an outside reviewer looked at how that pharmacy compounds and confirmed it measures up. Earning it takes months and a real review, so it is a meaningful signal, not a sticker a pharmacy can simply buy. If a compounding claim matters to you, asking about PCAB is a fair and useful question.

What this means for you

You do not need to memorize these numbers. The point is simple: there are real national standards behind a good compounded medication, and you have every right to ask a pharmacy how it follows them. A pharmacy that compounds well will be glad to explain it.

Five questions to ask any compounding pharmacy

1. 1Which USP standards do you follow for the kind of medication I need, non-sterile or sterile?
2. 2Who makes my compound, and how are they trained and checked?
3. 3How do you test or verify that the strength and quality are right?
4. 4Are you PCAB accredited, or working toward it? What does your accreditation cover?
5. 5If my medication is a hazardous drug, how do you handle it safely under USP 800?
