Biologic medications are used to treat a wide range of diseases, including autoimmune disorders, cancer, and some genetic conditions.
A “biosimilar” medication is a type of drug that is very close to an original biologic medication, also called its “reference biologic.” Although not identical, the FDA carefully reviews each biosimilar to ensure it works the same way and is as safe and effective as its reference biologic. Both have been FDA approved. The main difference is that biosimilars may cost less than the original reference biologic.
Your Generations Advantage Part D formulary (list of covered drugs) includes some biosimilars. If you have been prescribed a reference biologic, you might save money by switching to its biosimilar medication. Talk with your doctor or pharmacist to see if a biosimilar is right for you.
