Compounded drugs may differ from commercial drugs in a number of ways, such as: Dose, Dosage Form, Route of Administration, Additional Active Ingredients, Excipients / Inactive Ingredients, etc.
Therefore the safety & efficacy profile of any specific compounded drug is not directly comparable to commercially available medications.
Clinical Studies on the effects of commercially available medications (as part of their approval process or in follow-up research) should not be read to indicate the same results would occur with a compounded medication. Individual compounded drugs have not been studied for safety & efficacy by the FDA, and are not FDA-approved. The changes made to a compounded drug are based on the prescription written by a medical professional. Compounds are sent for third-party analysis and quality control before being available to patients for dispensing.
