Key Points

Jardiance is a sodium-glucose cotransporter-2 (SGLT-2) inhibitor used in addition to diet and exercise to help control blood glucose (sugar) in adults and children 10 years of age and older with type 2 diabetes. It lowers blood sugar by blocking proteins in the kidney to increase glucose excretion through the urine.

Jardiance also lowers the risk of a heart-related death (like a stroke or heart attack) in adults who have heart disease and reduces the risk of hospitalization and death due to heart failure (when the heart is weak and cannot pump enough blood to the rest of your body) in adults with heart failure. Over time, high blood sugar levels can cause plaque to build up in your blood vessels, which elevates your risk for heart disease.

It is also used to lower the risk of worsening kidney disease, kidney failure, cardiovascular death and hospitalizations in adults with chronic kidney disease (CKD) at risk of progression. They also protect the kidneys in people with CKD who do not have diabetes.

How does Jardiance work?

Jardiance (empagliflozin) is classified as an SGLT-2 (sodium-glucose cotransporter-2) inhibitor. SGLT-2 proteins are located in the renal tubules of the kidneys and are responsible for reabsorbing glucose back into the blood. Jardiance blocks the action of the SGLT-2 proteins. As a result, more glucose is excreted in the urine.

SGLT-2 inhibitors have been shown to be effective at lowering hemoglobin A1C levels, improving weight loss and lowering blood pressure. In kidney disease, SGLT-2 inhibitors lower the reabsorption of sodium and glucose in the proximal tubule of the kidney to help protect the kidney.

Jardiance can be added to other medicines for type 2 diabetes in adults such as metformin, sulfonylureas, pioglitazone, and insulin as well as other heart medications like statins, beta blockers, ACE inhibitors, and diuretics. In children, the only other oral medicine approved for type 2 diabetes is metformin.

When used alone, SGLT-2 inhibitors carry a low risk of hypoglycemia (low blood sugar levels). However, your doctor may need to lower your dose of Jardiance if you take it with other drugs that also cause low blood sugar, like insulin or sulfonylureas.

Other FDA approved medications in the SGLT-2 inhibitor class include:

  • bexaglifloxin (Brenzavvy)
  • canagliflozin (Invokana)
  • dapagliflozin (Farxiga)
  • ertugliflozin (Steglatro)

These medicines come as single-ingredient products or combined with other diabetes medicines

How can Jardiance help me with my type 2 diabetes?

In type 2 diabetes your body does not make enough insulin, the insulin you do make does not work as well, and you may make too much glucose (sugar). When this happens, glucose builds up in your blood and can lead to serious health conditions with the heart, kidney, nerves, blood vessels and eyes. Diet, exercise, and use of special medications can help to lower your blood sugar and risks from type 2 diabetes.

Many patients first diagnosed with type 2 diabetes start on an oral medication known as metformin. It’s in the class of drugs known as biguanides. It increases the cells ability to use glucose (blood sugar) by improving how your insulin works and decreases liver glucose production and absorption.

However, some patients cannot reach their blood sugar goal with metformin alone and need extra medication.

Jardiance can be added to metformin or other medications to help you reach your A1C goal. A1C is a simple blood test that shows the average amount of sugar (glucose) in your blood over the past 2 to 3 months, letting you know how well your blood sugar is being controlled over time.

Who should not use Jardiance?

  • Jardiance should not be used in people with type 1 diabetes or diabetic ketoacidosis (increased ketones in the blood or urine). Use in patients with type 1 diabetes may increase the risk for diabetic ketoacidosis in these patients.
  • You should not use Jardiance if you have a history of a serious allergic reaction to Jardiance of any of its ingredients.
  • You also should not use this drug if you have severe kidney (renal) disease, end-stage renal disease, or are on dialysis. Your doctor will check your kidney function before you begin treatment with Jardiance. Jardiance may not work if you have severe kidney problems.

How do I take Jardiance?

  • Take Jardiance once each day exactly as your doctor tells you. It comes in a 10 mg or 25 mg tablet that you swallow.
  • The recommended dose of Jardiance is 10 mg once daily in the morning, taken with or without food. If you are tolerating Jardiance, the dose may be increased to 25 mg if you need it.
  • Your doctor will check your kidney function with a blood test before you start treatment. If you have a certain level of kidney disease, you may not be able to use Jardiance.
  • Do not take Jardiance if you are allergic to any of its ingredients.

Jardiance is not approved for use by anyone younger than 10 years of age.

Important side effects with Jardiance

Jardiance is usually well-tolerated. However, as with all drugs, there are important side effects and you should review and discuss with your doctor.

Serious side effects with Jardiance can include:

  • Ketoacidosis (increased ketones in your blood or urine)
  • Sudden kidney injury
  • Urinary tract infections
  • Dehydration (the loss of body water and salt)
  • Low blood sugar (hypoglycemia)
  • Necrotizing fasciitis (a rare but serious tissue infection under the skin that can happen around the anus and genitals)
  • Allergic reactions
  • Increased cholesterol

The most common side effects (5% or greater) that may occur with Jardiance are:

  • Urinary tract infections
  • Yeast infections
