Why this directory exists
We combine state board licensing data, FDA outsourcing registrations, and public regulatory notices to help prescribers find safe, patient-ready compounds.
What is a 503A pharmacy?
503A facilities are traditional compounders that prepare customized medications for individual patients with a valid prescription. They operate under state board of pharmacy oversight and must follow USP compounding standards. Our data highlights 503A pharmacies that advertise sterile or non-sterile capabilities so you can confirm they match the needs of your practice.
What is a 503B outsourcing facility?
503B outsourcing facilities can produce large batches of sterile drugs without patient-specific prescriptions. They register with the FDA, comply with current good manufacturing practices (cGMP), and undergo FDA inspections. We monitor inspection timelines, Form 483 citations, warning letters, and recall activity so you can gauge compliance history at a glance.
How we maintain the data
- Weekly ingestion of FDA outsourcing facility CSVs and state-level compounding listings
- Automated scripts to normalize addresses, phone numbers, inspection dates, and registration status
- Optional Google Places enrichment to validate coordinates and collect public reviews
- Manual verification for name changes and closures flagged by state regulators
