Why compounded drugs are not FDA-approved
It's not a flaw — it's the category.
Compounded drugs are not FDA-approved. That's not a hidden problem; it's how the 503A statute works. This page explains what that means and what it doesn't mean.
What FDA approval covers
Manufactured drugs, mass-produced, identical doses.
FDA approval applies to manufactured drugs that go through the FDA's approval process: clinical trials, manufacturing inspections, labeling review. Approved drugs are mass-produced and identical from one bottle to the next.
FDA approval doesn't cover patient-specific compounded medication, because each compounded prescription is prepared for an individual patient based on a doctor's prescription, not mass-produced.
What compounding offers
Customization on a doctor's prescription.
Compounded medication exists for cases the manufactured supply doesn't cover well: a different strength, a different dosage form, an excipient the patient can't tolerate, a combination the manufactured market doesn't make.
Because compounded drugs are prepared per patient-specific prescription, they aren't FDA-approved as a class. They are regulated by state boards of pharmacy under 503A and by the pharmacist's professional standards.
How to evaluate compounded drugs
Not by branded-drug data.
Compounded drugs should not be evaluated using branded-drug trial data. They are not generic equivalents of approved drugs. The decision to use a compounded drug is a clinical decision the prescribing doctor makes, based on the patient's needs and the doctor's judgment.
If a patient asks whether a compounded medication is 'the same as' an FDA-approved drug, the honest answer is: no. It is prepared for that patient, by prescription, in a state-licensed 503A pharmacy.
Compounded drugs are not FDA-approved. They are prepared for identified patients based on lawful prescribing and patient-specific need. Availability varies by state and prescribed medication.
