Compounding Pharmacy
A compounding pharmacy custom-makes prescription medications a manufacturer doesn't — different strengths, different forms, allergen-free, or to replace discontinued drugs. Compare licensed U.S. compounding pharmacies for free.
What is a compounding pharmacy?
A compounding pharmacy is a state-licensed pharmacy that prepares prescription medications from individual pharmaceutical-grade ingredients, rather than dispensing mass-manufactured products. Compounding is regulated under Section 503A of the Federal Food, Drug, and Cosmetic Act for patient-specific prescriptions, and under Section 503B for outsourcing facilities that supply clinics in larger batches. Every compound requires a valid prescription from a licensed prescriber.
Patients turn to compounding for four common reasons: a commercial drug has been discontinued or is on FDA shortage (like Aphthasol or methimazole), the standard formulation contains an allergen or filler they react to (lactose, gluten, dyes), they need a strength or dosage form the manufacturer doesn't make (a child-friendly suspension, a transdermal cream, a sublingual troche), or their prescriber has determined a combination formulation is clinically appropriate.
Compounding has existed since pharmacy began — it's how all medications were made before industrial manufacturing — and remains a small but vital category of modern healthcare. The U.S. has roughly 7,500 active compounding pharmacies, most of which ship nationally under non-resident pharmacy licenses.

How to find a compounding pharmacy near you
You can find a compounding pharmacy three ways: ask your prescriber (most have a relationship with one local pharmacy), search your state board of pharmacy directory, or compare quotes through a directory that gathers pricing across pharmacies. Because cash prices for the same prescription often differ by double or more between pharmacies, comparing matters more than proximity — most compounding pharmacies ship overnight nationally.

Compounding pharmacy FAQ
What does a compounding pharmacy do?
A compounding pharmacy prepares prescription medications from individual ingredients to meet a specific patient's needs — different strength, different formulation (cream, troche, suspension), without an allergen, or to replace a discontinued commercial drug. Every compounded medication requires a valid prescription from a licensed prescriber.
Is a compounded medication FDA-approved?
Compounded medications themselves are not FDA-approved as finished products, because they are made for an individual patient rather than mass-manufactured. The active ingredients used must come from FDA-registered facilities, and the pharmacies are regulated under Section 503A (patient-specific) or 503B (outsourcing facilities) of the Federal Food, Drug, and Cosmetic Act, plus state boards of pharmacy.
Why do compounding pharmacy prices vary so much?
Two pharmacies preparing the same medication can quote very different prices based on bulk API costs, batch size, equipment, sterile vs. non-sterile facility overhead, shipping radius, and margin. On almost half of the requests we compared, the highest quote for the same compounded prescription was at least double the lowest. Comparing quotes is the only way to know.
How do I find a reputable compounding pharmacy?
Look for state pharmacy board licensure where you live (compounding pharmacies must be licensed in every state they ship to), PCAB accreditation for sterile compounding, and clear pricing. Through Compounding Finder you can compare quotes from licensed U.S. compounding pharmacies that serve your state for free — submit your prescription details once and receive multiple anonymous quotes within 1–2 business days.
Will my insurance cover compounded medications?
Most commercial insurance plans do not cover compounded medications, though some PPOs reimburse a portion if you submit a manual claim. Medicare Part D coverage is rare. Because cash pricing is the norm, comparing pharmacies makes a meaningful difference — patients who compared quotes chose one a median of about $46 per fill below the average of their other quotes.
Can a compounding pharmacy ship to my state?
Yes, if it is licensed for your state: a pharmacy outside your state needs a non-resident license or registration from your state to ship to you. When you request quotes through Compounding Finder, your request goes only to pharmacies that tell us they serve your state.
What is the difference between 503A and 503B compounding pharmacies?
503A pharmacies compound patient-specific prescriptions (one Rx, one patient). 503B outsourcing facilities can produce larger batches without patient-specific prescriptions and operate under stricter cGMP standards similar to drug manufacturers — typically supplying clinics and hospitals. Most retail compounding for individuals is 503A.
