  • History of urinary tract infections or genital yeast infections. Jardiance can increase your risk of urinary tract infections (UTIs) and genital yeast infections. If you have a history of either, you may have a higher risk with Jardiance. Be sure that your doctor is aware of any UTIs or yeast infections you’ve had in the past.

How does Jardiance work?

Jardiance works by preventing blood sugar from moving from your bloodstream into your cells when your blood is filtered by your kidneys. This helps your body get rid of glucose through your urine, lowering the amount of glucose in your blood. So, your blood sugar levels become lower.

If you’d like to know more about how Jardiance works, talk with your doctor or pharmacist.

If you have diabetes, your doctor may recommend Jardiance. It’s used in adults with type 2 diabetes.

Diabetes is a chronic (long-lasting) condition that causes high blood sugar levels. It happens when your body either doesn’t make enough insulin or doesn’t respond properly to insulin. (Insulin is a hormone that helps lower your blood sugar levels.)

With high blood sugar levels, your heart and blood vessels can become damaged over time.

Jardiance works to lower blood sugar levels by helping your body eliminate sugar. This way, your blood sugar levels don’t become high.

Note: Jardiance isn’t meant to be used by people who have type 1 diabetes. It’s also not meant to treat diabetic ketoacidosis, a buildup of acid caused by high blood sugar levels.

The costs of prescription drugs vary, depending on many factors. These include what your insurance plan covers and which pharmacy you use.

If you have questions about how to pay for your prescription, talk with your doctor or pharmacist. You can also visit the Jardiance manufacturer’s website to see if they have support options.
