What is Farxiga® (dapagliflozin) used for?
Farxiga® is an oral diabetes medicine that helps control blood sugar levels. Dapagliflozin works by helping the kidneys get rid of glucose from your bloodstream.
Farxiga® is used together with diet and exercise to treat type 2 diabetes.
Farxiga® is not for treating type 1 diabetes.
How should I take Farxiga® (dapagliflozin)?
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, if you consume less food or fluid than usual, or if you are sweating more than usual.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
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®.
