Farxiga vs. Glimepiride
See how Farxiga and Glimepiride compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Farxiga is an SGLT2 inhibitor that lowers blood sugar and also protects the heart and kidneys, while glimepiride is an older sulfonylurea used only for blood sugar control.
Glimepiride carries a real risk of hypoglycemia because it pushes the pancreas to release more insulin, while Farxiga's blood sugar effect does not typically cause lows on its own.
Farxiga costs far more out of pocket than glimepiride, which is one of the least expensive diabetes pills available.
Farxiga vs. Glimepiride Drug Summary
Farxiga
Farxiga (dapagliflozin) is an SGLT2 inhibitor that lowers blood sugar by causing the kidneys to remove excess glucose through urine. It is FDA-approved for type 2 diabetes, heart failure, and chronic kidney disease, and is taken as one tablet by mouth once a day.
Glimepiride
Glimepiride is a sulfonylurea that lowers blood sugar by stimulating the pancreas to release more insulin. It is FDA-approved only for type 2 diabetes as an add-on to diet and exercise, and is taken as one tablet by mouth once a day, with the dose slowly increased over time.

Farxiga vs. Glimepiride Indications
Farxiga
Farxiga is approved to control blood sugar in adults and children 10 and older with type 2 diabetes. It also carries separate approvals for reducing heart failure hospitalization, treating heart failure across ejection fraction types, and slowing chronic kidney disease progression.
Type 2 diabetes blood sugar control (ages 10+)
Heart failure treatment across ejection fraction types
Chronic kidney disease progression and cardiovascular risk
Reduces risk of heart failure hospitalization in at-risk patients
Glimepiride
Glimepiride is approved only to control blood sugar in adults with type 2 diabetes, used alongside diet and exercise. It carries no heart failure or kidney disease approval, unlike newer diabetes drug classes, and is not approved for use in children or for type 1 diabetes.
Type 2 diabetes blood sugar control in adults
Used as an adjunct to diet and exercise
Can be combined with other diabetes medications
Not approved for pediatric patients or other conditions
Farxiga vs. Glimepiride Pros and Cons
Farxiga
Farxiga's broad set of FDA approvals means it can address heart failure and kidney disease risk at the same time as blood sugar control, which matters for many people with type 2 diabetes. It carries a higher price tag and specific genitourinary risks that glimepiride does not share.
Pros
FDA-approved for heart failure and chronic kidney disease, not just diabetes
Low risk of causing hypoglycemia when used alone
Approved for children 10 and older with type 2 diabetes
May promote modest weight loss
Cons
Roughly $400 to $785 per month without insurance, before savings programs
Risk of genital yeast infections and urinary tract infections
Carries a rare but serious Fournier's gangrene warning
Not recommended once kidney function drops below a certain level
Glimepiride
Glimepiride is a decades-old, inexpensive option that lowers blood sugar reliably, but it works only on glucose control and carries a meaningful risk of low blood sugar. It has no heart or kidney benefit and needs a slower dose increase to find an effective level.
Pros
Roughly $10 to $20 per month, one of the least expensive diabetes pills
Decades of clinical use and prescribing experience
Simple once-daily oral dosing after titration
Can be combined with metformin or insulin for added effect
Cons
Meaningful risk of hypoglycemia, especially with missed meals
No heart failure or kidney disease benefit
Requires gradual dose titration over several weeks
Possible link to increased cardiovascular mortality per older studies
