What Is Farxiga Used For?

Farxiga improves blood sugar control in adults and children ages 10 and older with type 2 diabetes when used with diet and exercise. In adults, it also reduces certain risks linked to heart failure and chronic kidney disease. The reason for prescribing it affects the dose and the tests needed before treatment.

How Does Farxiga Work?

Farxiga blocks a kidney protein that normally returns glucose to the bloodstream. More glucose then leaves the body in urine, which helps lower blood sugar. Its effects on the heart and kidneys also support its use for certain adults with heart failure or chronic kidney disease.

How Is Farxiga Taken?

Farxiga is a tablet taken by mouth once daily. A clinician checks kidney function and assesses fluid status before treatment. The prescribed dose depends on whether the medicine is being used for blood sugar control or another approved purpose.

What Are the Side Effects and Precautions?

Genital yeast infections and urinary tract infections can occur. Farxiga can also cause dehydration and, in some circumstances, a serious condition called ketoacidosis. Tell a clinician about planned surgery, reduced food intake, or symptoms such as nausea, vomiting, or trouble breathing.

Frequently Asked Questions About Farxiga

Is Farxiga insulin?

No. Farxiga is an oral sodium-glucose cotransporter 2 inhibitor. It works through the kidneys rather than replacing insulin.

Can Farxiga be prescribed without diabetes?

Yes. It has approved uses for certain adults with heart failure or chronic kidney disease, including people without diabetes.

Is Farxiga used for type 1 diabetes?

It is not recommended to improve blood sugar control in people with type 1 diabetes. Ketoacidosis is a concern with this drug class.

Should Farxiga be stopped before surgery?

It may need to be paused before surgery or prolonged fasting. Ask the prescribing clinician when to stop and restart it.
