Dapagliflozin can also cause infections in the bladder or genitals (penis or vagina). Call your doctor if you have genital pain or itching, genital odor or discharge, increased urination, pain or burning when you urinate, or blood in your urine.

How should I take dapagliflozin?

Dapagliflozin is usually taken once per day in the morning. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.

You may take dapagliflozin with or without food.

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.

Your blood sugar will need to be checked often, and you may also need to test the level of ketones your urine. Dapagliflozin can cause life-threatening ketoacidosis (too much acid in the blood). Even if your blood sugar is normal, contact your doctor if a urine test shows that you have ketones in the urine.

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 dapagliflozin.

Dapagliflozin 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.
