What is Farxiga?

Farxiga is a diabetes medicine that can be taken by mouth and helps keep blood sugar levels in check. Dapagliflozin works by making it easier for the kidneys to get rid of glucose from the blood.

Farxiga is used with a healthy diet and exercise to help people with type 2 diabetes mellitus better control their blood sugar. This medicine is not used to treat diabetes type 1.

Farxiga is also used to lower the chance that an adult with type 2 diabetes and heart disease will die from a heart attack, stroke, or heart failure.

Farxiga is also used to lower the chance that an adult with type 2 diabetes and heart disease will need to go to the hospital for heart failure.

Farxiga is also given to people with chronic kidney disease to lower the chance that their condition will get worse, that they will die from heart disease, or that they will have to go to the hospital for heart failure.


If you have diabetic ketoacidosis, serious kidney disease, or are on dialysis, you shouldn’t use Farxiga.

Tell your doctor if you have diarrhea or vomiting, or if you aren’t eating or drinking as much as normal.

Taking Farxiga can make you lose water, which can make you feel weak or dizzy, especially when you stand up.

Farxiga can lead to dangerous infections in the penis or vagina. Get medical help right away if your genital or rectal area is burning, itching, smelly, bleeding, sore, painful, red, or swollen, or if you have a fever or don’t feel well.

Some people who took this drug got bladder cancer, but it’s not clear if dapagliflozin was really the cause.

Before you take this drug

Farxiga shouldn’t be used if you are allergic to dapagliflozin or if you have:

  • Serious kidney disease (or are on dialysis) or
  • Diabetic ketoacidosis (call your doctor for treatment).

To make sure Farxiga is safe for you, tell your doctor if you have ever had:

  • Polycystic kidney disease;
  • Liver disease;
  • Bladder infections or other urination problems;
  • Problems with your pancreas, including surgery;
  • Alcoholism or if you drink a lot of alcohol now; or
  • If you are on a low-salt diet.

If you are pregnant or think you might be pregnant, follow your doctor’s advice about how to use Farxiga. During pregnancy, it is very important to keep diabetes under control.

If you are in your second or third stage of pregnancy, you shouldn’t take dapagliflozin.

Dapagliflozin should not be used during the second or third trimester of pregnancy.

How should I take Farxiga?

Take Farxiga exactly as your doctor has told you to. Follow all of the rules on the label of your prescription, and read any guides or instruction sheets that come with it. Your doctor may change your dose from time to time.

Farxiga can be taken with or without food.

You will need to check your blood sugar often, and you may also need to check how many ketones are in your pee. Ketoacidosis, which is too much acid in the blood, can kill you if you take Dapagliflozin. Even if your blood sugar is fine, if a pee test shows that you have a lot of ketones in your urine, you should talk to your doctor.

Stress, illness, surgery, exercise, drinking booze, and skipping meals can all have an effect on blood sugar.

Hypoglycemia, or low blood sugar, can make you feel very hungry, sick, angry, or shaky. Eat or drink hard candy, crackers, raisins, fruit juice, or regular soda to treat hypoglycemia fast. In the case of extreme hypoglycemia, your doctor may give you a glucagon injection.

Getting sick for a long time can make you lose water. If you have diarrhea or vomiting, or if you eat or drink less than normal, you should call your doctor.

Some medical tests may not be accurate if you take this medicine. Tell any doctor who sees you that you are taking Farxiga.

Your treatment may also include what you eat, how much you move, how you control your weight, and special medical care.

Keep at room temperature and away from heat and moisture.
