How does generic Januvia differ from the brand-name drug?
Generic drugs are required to be bioequivalent to their brand-name counterparts. This means they contain the same active ingredient (sitagliptin), dosage form, strength, and route of administration, and are expected to have the same clinical effect [1]. Differences may exist in inactive ingredients, which are not typically therapeutic [1].
Can biosimilars be made for Januvia?
Januvia is a small molecule drug, not a biologic. Therefore, biosimilars, which are versions of biologic drugs, are not applicable. Generic versions are the appropriate follow-on products for small molecule drugs like sitagliptin [4].
What are the risks of switching to generic Januvia?
For most patients, switching to a generic version of Januvia is safe and effective. However, individuals with sensitivities to specific inactive ingredients should consult their doctor or pharmacist. The Food and Drug Administration (FDA) mandates that generic drugs meet the same strict quality and safety standards as brand-name drugs [1].

How does sitagliptin work?
