Short answer: For blood sugar control in type 2 diabetes, the Farxiga label starts at 5 mg once daily, which can go up to 10 mg. For chronic kidney disease, heart failure and heart failure risk in type 2 diabetes, the dose is 10 mg once daily. It is held for at least 3 days before surgery when possible. A missed dose is taken as soon as possible, without doubling the next.
This is what the FDA label says. Follow your prescriber. Your prescriber may use a different dose or pace than the label's standard schedule.
What Farxiga is approved for: Farxiga is an SGLT2 inhibitor approved to lower the risk of kidney decline, end-stage kidney disease, cardiovascular death and heart failure hospitalization in adults with chronic kidney disease at risk of progression; to lower the risk of cardiovascular death, heart failure hospitalization and urgent heart failure visits in adults with heart failure; to lower the risk of heart failure hospitalization in adults with type 2 diabetes and heart disease or several heart risk factors; and, with diet and exercise, to improve blood sugar in adults and children 10 and older with type 2 diabetes (section 1). It is not for blood sugar control in type 1 diabetes.

Farxiga is a tablet taken by mouth once daily, with or without food (Medication Guide). It comes in 5 mg and 10 mg tablets (section 3).
Before starting, kidney function and fluid status are assessed, and fluid loss is corrected first (section 2.1).
Farxiga is held for at least 3 days, if possible, before surgery or procedures with prolonged fasting, and restarted once the person is stable and eating and drinking again (section 2.4).
The table below is the label's schedule, from the Dosage and Administration section. Numbers are copied exactly; the section is in brackets.
| Use | Dose | Kidney function limits on the label |
|---|---|---|
| Blood sugar control, adults and children 10 and older with type 2 diabetes | Start 5 mg once daily; can be increased to 10 mg once daily for additional glycemic control | Same dose at eGFR 45 or more; not recommended for blood sugar control below eGFR 45 |
| Chronic kidney disease at risk of progression (adults) | 10 mg once daily | Starting not recommended below eGFR 25; if eGFR falls below 25 on treatment, 10 mg may continue |
| Heart failure (adults) | 10 mg once daily | Starting not recommended below eGFR 25; if eGFR falls below 25 on treatment, 10 mg may continue |
| Heart failure hospitalization risk in type 2 diabetes with heart disease or risk factors (adults) | 10 mg once daily | Starting not recommended below eGFR 25 |
Kidney function is assessed before starting and as clinically indicated. Fluid status is assessed and fluid loss corrected before starting.
Farxiga is withheld for at least 3 days, if possible, before surgery or procedures with prolonged fasting, and resumed when the person is clinically stable and eating and drinking again.
With insulin or a sulfonylurea, a lower dose of those medicines may be needed to reduce the risk of low blood sugar.
With lithium, serum lithium is checked more often when Farxiga is started or its dose changes.
No dose change is recommended based on age.
No dose change is recommended for liver impairment, though use in severe liver impairment is weighed individually because it was not specifically studied.
If a dose is missed, it is taken as soon as possible, and the next dose is not doubled. The Medication Guide adds: if it is almost time for the next dose, skip the missed dose and take the medicine at the next regularly scheduled time; do not take 2 doses at the same time.
More on this: missed a dose of Farxiga.
In Dose Track you set up Farxiga as a protocol with the dose and schedule your prescriber gave you. A protocol can hold dose steps, each with its own dose and length in days or weeks, so a step-up plan like the one on the label can be entered once and the app moves to the next step on its own. Reminders follow the schedule, and every dose is logged with the date and time, so you can see which step you are on and when your last dose was. The app follows what you enter; it does not choose or change a dose.
