May a Biosimilar Be Used in Place of a Reference Product?

Pharmacists are not permitted to automatically substitute a biosimilar for its reference product; they would need to contact the prescriber to approve the switch. Currently, the health care provider must write the specific name of the biosimilar product on the prescription. However, the BPCIA includes a provision to allow for “interchangeable” biological products: biosimilars that may be substituted for the reference product by a pharmacist without the intervention of the health care provider who prescribed the reference product.
