Dapagliflozin and metformin may rarely cause a serious and sometimes fatal condition called lactic acidosis. Most of these cases have occurred in diabetic patients who also have certain kidney problems. The risk of lactic acidosis may be greater if you have liver problems, kidney problems, or heart failure. The risk may also be greater in patients who are elderly or drink alcohol. Lab tests, including kidney function, may be performed while you take dapagliflozin and metformin.
Do not begin to take dapagliflozin and metformin if you are 80 years old or older unless lab tests show that you do not have decreased kidney function. Do not take it if you have a severe infection, have low blood oxygen levels, or are dehydrated. Tell your doctor you take dapagliflozin and metformin before you have any surgery or lab procedures.
Contact your doctor right away if you notice symptoms such as muscle pain or tenderness; unusual drowsiness, dizziness, or light-headedness; slow or irregular heartbeat; fast or difficult breathing; unusual stomach discomfort; or unusual weakness or tiredness. Contact your doctor right away if you start to feel unusually cold or if you have a general feeling of being unwell.
Dapagliflozin and metformin is used for:
Treating type 2 diabetes in certain patients. It is used along with diet and exercise.
Dapagliflozin and metformin is a sodium-glucose cotransporter 2 (SGLT2) inhibitor and biguanide antidiabetic combination. The SGLT2 inhibitor works by decreasing the amount of sugar the body absorbs and increasing the amount of sugar that leaves the body in the urine. The biguanide antidiabetic works by decreasing the amount of sugar that the liver produces and the intestines absorb. It also helps to make your body more sensitive to the insulin that you naturally produce.
Do NOT use dapagliflozin and metformin if:
- you are allergic to any ingredient in dapagliflozin and metformin
- you have type 1 diabetes
- you have a severe infection, low blood oxygen levels, moderate to severe kidney problems, liver problems, high blood or urine ketone levels (diabetic ketoacidosis), dehydration, or bladder cancer
- you have had a stroke or a recent heart attack, or you are in shock
- you are 80 years old or older and have not had a kidney function test

It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or nondiet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
