Before you hand a prescription to a compounding pharmacy, ask seven questions: who licenses them, which USP standards they work to, whether they are a 503A or 503B operation, what they test, where their ingredients come from, what goes on the label, and how a pharmacist communicates with your prescriber. Answers arrive in under a minute when the pharmacy does this work every day — and the quality of those answers tells you most of what you need to know.
Compounded medications are prepared for individual patients rather than mass-manufactured, which is exactly why the pharmacy you choose matters more than it would for an off-the-shelf refill.
The seven questions
1. "Who licenses you, and who is your pharmacist-in-charge?"
Compounding pharmacies operate under state pharmacy law. Your state's board of pharmacy issues the license, inspects the facility, and holds a named pharmacist-in-charge responsible for it. The FDA is clear that state boards, not the FDA, license the pharmacies that compound for individual patients. Ask for the license and the pharmacist-in-charge's name; a straight answer is normal, and evasiveness is the finding.
2. "Which USP standards do you follow?"
The United States Pharmacopeia sets the operational standards for compounding in General Chapters: USP 795 for nonsterile preparations (capsules, creams, suspensions), USP 797 for sterile preparations (injectables, eye drops), and USP 800 for handling hazardous drugs. Each chapter specifies facility design, equipment, personnel training and certification, labeling, and beyond-use dating. Your pharmacy should be able to say which chapters apply to your prescription and how compliance is documented — not just that they "follow FDA guidelines."
3. "Are you a 503A pharmacy or a 503B outsourcing facility?"
The distinction is legal, not marketing. A 503A pharmacy compounds medication for an identified patient against a valid prescription and is licensed by the state. A 503B outsourcing facility may manufacture larger quantities without patient-specific prescriptions and must register with the FDA. Both have roles; they are regulated differently. What matters for you is that the pharmacy is operating under the category it claims.
4. "What do you test, and on what schedule?"
Quality controls should be specific to the preparation. Potency testing confirms the medication contains what the label says. Sterile preparations require sterility testing. Beyond-use dates must be justified rather than assumed. Ask how results are recorded and what happens when a batch fails. A pharmacy that can walk you through a recent example is a pharmacy with a functioning quality system.
5. "Where do your ingredients come from?"
Active pharmaceutical ingredients should come from qualified suppliers with documentation — certificates of analysis confirming identity and purity. Excipients (the capsule, the cream base, the flavoring) matter too, particularly for patients with allergies to dyes, gluten, or preservatives. This is often the whole reason someone needs a compound in the first place, so the pharmacy should be fluent in its supply chain.
6. "What exactly will be on my label, and what is the price?"
Dispensing requirements for patient-specific compounded medications include listing the active ingredients and their quantities on the label — you should never be guessing what you are swallowing. Pair that with an itemized price before compounding starts. Our own practice matches it: ingredients and total, quoted up front (see how compounded medications are priced).
7. "How does a pharmacist reach my prescriber?"
Compounding happens at the intersection of the prescription and the preparation. If the pharmacy spots a strength that does not make clinical sense, an interaction, or a stability concern, there should be a direct line to your prescriber — and a documented answer. Ask how quickly they typically get a prescriber on the phone, and whether consultations happen before your first fill, not after.
Red flags worth walking away over
- No license number offered when asked directly.
- Bulk quantities sold without a prescription — a regulatory line, not a convenience.
- Refusal to itemize ingredients or quote a price before making the medication.
- Claims that a compound treats conditions the FDA-approved product never covered — compounding is not a back door around FDA approval.
- No named pharmacist-in-charge, or no way to reach a pharmacist at all.
What we'd expect when you ask us
ExpressRx is a state-licensed Ohio pharmacy led by a physician-pharmacist team, working to USP standards with a documented quality system, itemized quotes before compounding, and a pharmacist reachable day and night. Our compounding service page describes the dosage forms we prepare; if you want the plain-language primer first, start with what compounded medication actually is.
How to actually ask these questions
The questions matter less than how you put them:
- Call, don't interrogate at the counter. A phone call with the pharmacist — not the technician on a busy line — gives honest room for real answers. Ask to speak to the pharmacist-in-charge by name.
- Bring your prescription, not just curiosity. Questions land better when they are concrete: "I need a dye-free 40 mg suspension for my daughter — how would you compound it, what would be in it, and what would it cost?"
- Write the answers down. License number, USP chapters, testing approach, quote. Three pharmacies compared side by side makes the differences obvious within a week.
- Visit if you can. You do not need a tour to notice whether the compounding area is clean, separated, and organized — the physical space tells you something the brochure will not.
- Transfer is easy; a bad fit is not. Moving a prescription takes one phone call (see how transfers work), so it costs you nothing to ask these questions before you settle in.
What "FDA-approved" means — and what it doesn't
The phrase gets stretched in compounding marketing, so it helps to draw the line cleanly. FDA approval applies to a specific manufactured product: its manufacturing facility, its labeled uses, and its evidence package. Compounded preparations are made for individual patients and are not FDA-approved as products — the FDA is explicit about this. That is not a criticism of compounding; it is the legal design. Compounding exists because some patients need a preparation that manufactured products do not provide.
What should give you pause is language that blurs the two categories — "FDA-approved formula," "the same as the approved drug," or ingredient-quality claims used to imply finished-product approval. Ingredient quality is real and worth asking about (that is question five), but it is not the same claim as product approval. A pharmacy confident in what it does explains the distinction comfortably; one that leans on the ambiguity is marketing rather than practicing.
Our answers, for comparison
So you have a baseline for what good answers sound like — here are ours, straight: we are a state-licensed Ohio pharmacy, physician-led, with pharmacists reachable 24 hours a day. Our compounding work follows the USP standards that apply to each preparation type, with documented calculations, beyond-use dating, and batch records for every preparation. You get an itemized price — each ingredient and the total — before anything is compounded, and your label lists the active ingredients and quantities. If something in your prescription looks off clinically, we call your prescriber before we make it, not after you have taken it.
If that reads like what you were hoping to hear from a compounding pharmacy, the next step is a two-minute call: bring your prescription, ask your seven questions, and let us answer them. Our compounding services page covers what we prepare; our FAQ covers everything else.

Frequently asked questions
How do I know if a compounding pharmacy is licensed?
Ask for the pharmacy's license and the name of the pharmacist-in-charge. In Ohio, compounding pharmacies are licensed and inspected by the Ohio State Board of Pharmacy, and the individual pharmacists hold state licenses you can verify. A reputable pharmacy answers this question in one sentence, without hedging.
Which USP standards should a compounding pharmacy follow?
USP General Chapters 795 for nonsterile preparations, 797 for sterile preparations, and 800 for handling hazardous drugs. Each standard sets requirements for facilities, equipment, personnel training, labeling, and beyond-use dates — your pharmacy should be able to name which ones apply to your prescription.
What is the difference between a 503A compounding pharmacy and a 503B outsourcing facility?
A 503A pharmacy compounds medication for an individual patient based on a prescription and is licensed by the state. A 503B outsourcing facility manufactures larger quantities without patient-specific prescriptions and must register with the FDA. If a pharmacy markets bulk quantities without prescriptions, that is a 503B question, not a 503A one.
Do compounded medications get tested?
Ask what testing applies to your preparation — potency testing confirms the strength, and sterile preparations require sterility testing. Laboratories should document results, and your pharmacy should be willing to describe its quality controls, its beyond-use dating, and how it records each batch.
Can I see the ingredients and price before it's made?
Yes. A compounding pharmacy should provide an itemized list of active ingredients, strengths, and the total price before compounding begins — plus the ingredient quantities that appear on your label. If a pharmacy will not itemize before you pay, that is a red flag.
