What Are Interchangeable Biological Products?

Interchangeable Biological Products

A biological product is interchangeable if it is biosimilar to the reference product and is expected to produce the same clinical result as the reference product in any given patient. A biosimilar product that is deemed to be interchangeable by the FDA means the biosimilar product can be substituted for the reference product by a pharmacist without consulting the prescriber. The specific requirements for substitution vary by state.
