Two medicines, side by side

Empagliflozin vs metformin

Empagliflozin and metformin are both labeled for type 2 diabetes. Drugs@FDA records approvals of empagliflozin since 2014 and of metformin since 1995. Pharmacies paid $11.19 per Jardiance 10 mg tablet and $0.0145 per metformin HCl 500 mg tablet (NADAC, October 7, 2026); the strengths differ and one is a brand and one a generic, so the two prices are not like for like. In FDA's classes, empagliflozin is a sodium-glucose cotransporter 2 inhibitor and metformin a biguanide.

Check it at the source: the empagliflozin FDA label on DailyMed (effective January 30, 2026); the metformin FDA label on DailyMed (effective September 3, 2026).

How do empagliflozin and metformin differ on the record?

In FDA's classes, empagliflozin is a sodium-glucose cotransporter 2 inhibitor and metformin a biguanide.

How each works, in its label's words: Empagliflozin, “Empagliflozin is an inhibitor of SGLT2, the predominant transporter responsible for reabsorption of glucose from the glomerular filtrate back into the circulation.”; Metformin, “Metformin is a biguanide that improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose.”

Only the metformin label carries a boxed warning.

Generics: empagliflozin since 2022; metformin since 2002 (Drugs@FDA).
