Compounded medications are patient-specific medications created in a state Board of Pharmacy or FDA licensed compounding facility per a prescription from a licensed healthcare professional. Compounded drugs are required to exclusively use ingredients from FDA-licensed facilities, and test sterile compounds for potency, sterility, and purity. While compounded drugs are legal they do not undergo pre-market approval from the FDA as they are not made in large batches for the public, compounds are made based on specific orders from a medical professional. Because of that the dose, route of administration, and efficacy may differ from commercially available, brand-name, drugs.
