What Is Farxiga?

Farxiga belongs to a class of medicines called SGLT2 inhibitors. These medications help the kidneys remove excess sugar and sodium from the body through urine. By doing this, Farxiga can improve blood sugar control and support heart and kidney health.

Farxiga is taken once daily by mouth, usually in the morning, with or without food. The 10 mg dose is the most common maintenance dose for most approved uses.

What Is Farxiga 10 mg Used For?

Farxiga is approved for several important medical conditions. Your doctor may prescribe it for one or more of the following:

1. Type 2 Diabetes

Farxiga helps lower blood sugar levels in adults with type 2 diabetes, especially when diet and exercise alone are not enough.

• Helps remove excess glucose through urine
• Lowers A1C (average blood sugar over time)
• May contribute to modest weight loss

Farxiga is not used for type 1 diabetes or diabetic ketoacidosis.

2. Heart Failure

Farxiga is approved to reduce the risk of hospitalization and death in adults with certain types of heart failure—even in people without diabetes.

• Helps the body get rid of extra fluid
• Reduces strain on the heart
• Can improve daily functioning and symptoms like shortness of breath

3. Chronic Kidney Disease (CKD)

Farxiga can slow the progression of kidney disease and reduce the risk of kidney failure in some adults.

• Protects kidney function over time
• Lowers the risk of dialysis or transplant
• Benefits seen with or without diabetes

How Farxiga Works (In Simple Terms)

Normally, your kidneys filter sugar out of the blood and then reabsorb it. Farxiga blocks that reabsorption, allowing extra sugar to leave the body through urine.

This leads to:

• Lower blood sugar levels
• Less fluid in the bloodstream
• Reduced pressure on the heart and kidneys

Because it increases urination, staying well hydrated is important.

What to Expect When Starting Farxiga

Many people tolerate Farxiga well, but your body may need some time to adjust.

Common Experiences in the First Few Weeks

• Increased urination
• Mild thirst
• Lower blood sugar readings
• Slight drop in blood pressure

These effects often settle as your body adapts. Your doctor may monitor kidney function and blood pressure, especially early on.

Possible Side Effects (What's Common vs. What's Serious)

More Common Side Effects

These are usually manageable and not dangerous, but still worth mentioning to your doctor:

• Urinary tract infections (UTIs)
• Genital yeast infections
• Increased urination
• Mild dizziness, especially when standing up
• Dehydration if fluid intake is too low

Because Farxiga causes fluid loss, it's important to recognize the warning signs early—if you're experiencing symptoms like unusual fatigue, dizziness, or dark urine, try Ubie's free AI-powered Dehydration symptom checker to better understand what your body might be telling you.

Less Common but Serious Side Effects

These are rare, but important to recognize:
