What is Farxiga?
Farxiga (dapagliflozin) is an oral diabetes medicine that helps control blood sugar levels. Dapagliflozin works by helping the kidneys get rid of glucose from your bloodstream.
You should not use Farxiga if you have severe kidney disease, if you are on dialysis, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin). Farxiga is not for treating type 1 diabetes.
Before taking this medicine
You should not use Farxiga if you are allergic to dapagliflozin, or if you have:
kidney disease (or if you are on dialysis);
bladder cancer; or
if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
To make sure Farxiga is safe for you, tell your doctor if you have:
low blood pressure;
high cholesterol levels.
a history of bladder cancer;
if you use insulin or take other oral diabetes medications;

How should I take Farxiga?
Farxiga is usually taken once per day in the morning. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
You may take Farxiga with or without food, but take it the same way each time.
Your blood sugar will need to be checked often, and you may need other medical tests at your doctor's office.
You may have very low blood pressure while taking Farxiga. Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, pale skin, irritability, dizziness, feeling shaky, or trouble concentrating. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.
If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.
Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your Farxiga dose or dosing schedule without your doctor's advice.
This medicine can cause positive results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using Farxiga.
Farxiga is only part of a treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature away from moisture and heat.
