Medically reviewed by Drugs.com. Last updated on Nov 14, 2022.

Usual Adult Dose for Diabetes Type 2

To improve glycemic control:
Initial dose: 5 mg orally once a day

• May increase to 10 mg orally once a day for additional glycemic control if lower dose has been tolerated

Maximum dose: 10 mg/day

To reduce the risk of hospitalization for heart failure: 10 mg orally once a day

Comments:

• Correct volume depletion prior to initiating therapy.
• Ensure adequate renal function (eGFR greater than 45 mL/min/1.73 m2) as glycemic efficacy is dependent on adequate renal function.
• If used in combination with insulin or an insulin secretagogue, a lower dose of insulin or the insulin secretagogue should be considered to reduce the risk of hypoglycemia.

Uses:

• As an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes mellitus.
• To reduce the risk of hospitalization for heart failure in patients with type 2 diabetes mellitus and established cardiovascular disease (CVD) or multiple cardiovascular (CV) risk factors.

Usual Adult Dose for Heart Failure with Reduced Ejection Fraction

10 mg orally once a day

Comments:

• Correct volume depletion prior to initiating therapy.
• This drug is not recommended for patients with type 1 diabetes mellitus.

Use: To reduce the risk of cardiovascular death and hospitalization for heart failure in adults with heart failure (NYHA class II-IV) with reduced ejection fraction.

Usual Adult Dose for Chronic Kidney Disease

10 mg orally once a day

Comments:

• Correct volume depletion prior to initiating therapy.
• This drug is not recommended in patients with polycystic kidney disease or patients requiring, or with a recent history of immunosuppressive therapy for kidney disease, as it is not expected to be effective.
• This drug is not recommended for patients with type 1 diabetes mellitus.

Use: To reduce the risk of sustained eGFR decline, end-stage kidney disease, cardiovascular death, and
hospitalization for heart failure in adults with chronic kidney disease at risk of progression.

Renal Dose Adjustments

For Glycemic Control in Patients with Type 2 Diabetes Mellitus:

• eGFR 45 mL/min/1.73 m2 or greater: No adjustment recommended
• eGFR less than 45 mL/min/1.73 m2: Use is not recommended

For all other indications:

• eGFR greater than 25 mL/min/1.73 m2: No adjustment recommended
• eGFR less than 25 mL/min/1.73 m2: Initiation is not recommended, however patients may continue 10 mg/day

Liver Dose Adjustments

General:

• Correct volume depletion prior to initiating treatment; dehydration may increase the risk for hypotension.
• Not recommended for patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis

Monitoring:

• Assess fluid status prior to initiation and monitor for signs and symptoms of volume depletion during therapy
• Obtain baseline renal function and monitor periodically during therapy
• Monitor for signs and symptoms of acute kidney injury
• Evaluate for ketoacidosis in symptomatic patients, even if blood sugar is below 250 mg/dL

Patient advice:

• Patients should be instructed to read the US FDA-approved patient labeling (Medication Guide).
• Patients should understand that this drug will cause the urine to test positive for glucose.
• Patients should be instructed to maintain adequate fluid intake.
• Patients should be instructed to seek medical advice during periods of stress or illness as medical management of diabetes may change.
• Patients should understand that genital mycotic infections, urinary tract infections, and hypersensitivity reactions may occur; patients should be instructed to contact their health care professional.
