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.
Farxiga is also used to lower the risk of death from heart attack, stroke, or heart failure in adults with type 2 diabetes who also have heart disease.
Farxiga is also used to lower the risk of further worsening of kidney disease, end-stage kidney disease (ESKD), death due to cardiovascular disease, and hospitalization for heart failure in adults with chronic kidney disease.
You should not use Farxiga if you have diabetic ketoacidosis, severe kidney disease, or if you are on dialysis.
Taking Farxiga can make you dehydrated, which could cause you to feel weak or dizzy (especially when you stand up).
Farxiga can cause serious infections in the penis or vagina. Get medical help right away if you have burning, itching, odor, discharge, pain, tenderness, redness or swelling of the genital or rectal area, fever, or if you don't feel well.
Some people taking this medicine have had bladder cancer, but it is not clear if dapagliflozin was the actual cause.

Blood sugar can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals.
Tell your doctor if you have frequent symptoms of high blood sugar (hyperglycemia) such as increased thirst or urination. Ask your doctor before changing your dose or medication schedule.
