503B vs. 503A: Which Type Do You Need?
Before you search, it helps to understand which type of compounding pharmacy you need:
You Need a 503B Outsourcing Facility If:
- You are a hospital or health system purchasing compounded drugs for patient administration
- You are an ambulatory surgery center stocking compounded medications for procedures
- You need bulk quantities of compounded sterile products without individual prescriptions
- You want products manufactured under cGMP standards with FDA oversight
- You are sourcing drug shortage alternatives for your facility
You Need a 503A Compounding Pharmacy If:
- You are a patient with a specific prescription from your doctor
- You need a custom formulation (specific dose, flavor, or dosage form) for an individual patient
- Your prescriber has written a patient-specific prescription for a compounded medication
- You are looking for a local retail pharmacy that offers compounding services

What to Look for When Choosing a Compounding Pharmacy
Finding a compounding pharmacy is just the first step. Evaluating whether it is the right partner requires checking several things:
For 503B Outsourcing Facilities
- FDA registration: Confirm the facility appears on the FDA's registered list
- Inspection history: Review Form 483 observations and warning letters on our inspection results page
- Product portfolio: Does the facility compound the drugs you need?
- Quality testing: Does the facility perform potency, sterility, and endotoxin testing on finished products?
- Beyond-use dating: Are BUDs supported by stability data?
- Supply reliability: Can the facility meet your volume and delivery requirements?
- Accreditation: Is the facility PCAB accredited?
For a complete evaluation framework, see our 503B Compounding Pharmacy Guide.
For 503A Compounding Pharmacies
- State licensure: Verify the pharmacy holds a current license from the state board of pharmacy
- PCAB accreditation: Look for voluntary accreditation as a quality signal
- Specialization: Does the pharmacy have experience with the type of compounding you need (sterile, non-sterile, hazardous)?
- USP compliance: Does the pharmacy follow USP <795> (non-sterile) and/or USP <797> (sterile) standards?
- Reputation: Check reviews, ask for references from other healthcare providers
Finding Compounding Pharmacies for Specific Medications
Some people search for compounding pharmacies based on a specific medication they need:
Compounded GLP-1 Medications (Tirzepatide, Semaglutide)
If you are looking for a compounding pharmacy for tirzepatide or semaglutide, see our dedicated guide: Compounded Tirzepatide & Semaglutide from 503B Pharmacies.
Sterile Injectable Medications
For sterile injectables (the most common 503B product category), search our 503B directory and filter for facilities in your state. Most 503B facilities specialize in sterile compounding.
Drug Shortage Alternatives
If you need a compounded alternative to a drug in shortage, 503B outsourcing facilities are your primary option. Check the FDA Drug Shortage Database to confirm the drug is in shortage, then search our directory for facilities that compound it.
Verifying a Compounding Pharmacy's Credentials
Before purchasing from any compounding pharmacy, verify its credentials:
- Check FDA registration (503B facilities only): FDA Registered Outsourcing Facilities
- Review inspection history: Search our inspection results page or the FDA's databases
- Verify state licensing: Check with the relevant state board of pharmacy
- Check for warning letters: Search the FDA Warning Letters Database
For a complete verification guide, see: How to Verify if a Compounding Pharmacy Is FDA Approved.
Frequently Asked Questions
How do I find a compounding pharmacy near me?
Use our 503B Pharmacy Directory to search for FDA-registered outsourcing facilities by state, or browse our 503B Pharmacies by State page. For 503A compounding pharmacies, check with your state board of pharmacy or ask your healthcare provider for a referral.
Are there compounding pharmacies in every state?
No. As of 2026, 503B outsourcing facilities are registered in 27 states, with concentrations in Florida, Texas, New Jersey, and California. However, most 503B facilities ship products nationwide, so geographic proximity is less important than quality and reliability.
Can a compounding pharmacy ship to my state?
503B outsourcing facilities typically distribute products across state lines. However, they may need to hold a non-resident pharmacy permit in the receiving state. Check with the facility and your state board of pharmacy to confirm they are authorized to ship to your location.
What is the difference between a compounding pharmacy and a regular pharmacy?
A regular (retail) pharmacy primarily dispenses commercially manufactured drugs. A compounding pharmacy prepares customized medications — different doses, dosage forms, or formulations — that are not commercially available. 503B outsourcing facilities are a specific type of compounding pharmacy that operates under FDA oversight and can produce medications in larger quantities without individual prescriptions.
How much do compounded medications cost?
Pricing varies significantly based on the medication, dosage form, quantity, and facility. Compounded medications from 503B facilities are generally less expensive than brand-name commercial products but may be more expensive than generic alternatives (when available). Contact facilities directly for pricing information.
