Xigduo XR (Dapagliflozin and Metformin) – Oral


Lactic acidosis: Xigduo XR may cause lactic acidosis (too much acid in the blood). This can result in hypotension (very low blood pressure), hypothermia (dangerously low body temperature), very slow heart rate with arrhythmias (irregular heartbeats), or death.

The risk is worse in people having surgery, exams, or contrast tests. The risk also increases in people with kidney or liver issues, heart failure, or who drink alcohol. If you have a slow or fast heartbeat, shortness of breath, muscle cramps, or feeling cold, stop taking Xigduo XR. Go to your nearest hospital and contact your healthcare provider.

What Is Xigduo XR?

Xigduo XR is a combination drug containing dapagliflozin (as found in the brand Farxiga) and metformin (as found in the brand Glucophage). It is commonly taken in addition to diet and exercise to help control blood sugar and treat adults with type 2 diabetes mellitus, a common chronic condition characterized by the way your body regulates and uses glucose as fuel.

This drug belongs to two drug classes: sodium-glucose cotransporter 2 (SGLT2) inhibitor and biguanides. This drug is used in adults. It is only available with a prescription and as a tablet.

Dapagliflozin stops your body from reabsorbing glucose. Hence, more glucose is flushed out of your body when you urinate. It may also help your heart work better.

Metformin lowers how much glucose your liver makes and the amount of glucose your body absorbs. It also increases insulin sensitivity in your body so that your body can readily use insulin.

It is very important that your doctor check your progress at regular visits, especially during the first few weeks that you take this medicine. Blood and urine tests may be needed to check for unwanted effects.

Serious allergic reactions may occur with this medicine. Check with your doctor right away if you have a skin rash, hives or welts, itching, redness of the skin, trouble breathing, or large, hive-like swelling on the face, eyelids, lips, tongue, throat, hands, legs, feet, or genitals.

Using this medicine during the second and third part of your pregnancy can harm your unborn baby. If you think you have become pregnant while using this medicine, tell your doctor right away.

This medicine may cause some women who do not have regular monthly periods to ovulate. This can increase the chance of pregnancy. If you are a woman of childbearing potential, you should discuss birth control options with your doctor.

It is very important to follow carefully any instructions from your doctor about:

  • Alcohol—Drinking alcohol may cause severe low blood sugar and increase risk for lactic acidosis. Discuss this with your doctor.
  • Other medicines—Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems.
  • Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, patients with diabetes may need special counseling about diabetes medicine dosing changes that might occur because of lifestyle changes, such as changes in exercise and diet. Furthermore, counseling on contraception and pregnancy may be needed because of the problems that can occur in patients with diabetes during pregnancy.
  • Travel—Keep a recent prescription and your medical history with you. Be prepared for an emergency as you would normally. Make allowances for changing time zones and keep your meal times as close as possible to your usual meal times.
  • In case of emergency—There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says that you have diabetes and a list of all of your medicines.

Under certain conditions, too much metformin can cause a serious condition called lactic acidosis. The symptoms of lactic acidosis are severe and appear quickly. Lactic acidosis usually occurs when other serious health problems are present, such as a heart attack or kidney failure. Check with your doctor right away if you have decreased appetite, diarrhea, fast or shallow breathing, a general feeling of discomfort, muscle pain or cramping, stomach discomfort, and unusual sleepiness, tiredness, or weakness.

Dizziness, lightheadedness, or fainting may occur with this medicine. This is more common if you have kidney disease, low blood pressure, or if you are taking a diuretic (water pill). Taking plenty of fluids each day may help. Drink plenty of water during exercise or in hot weather. Check with your doctor if you have severe nausea, vomiting, or diarrhea that does not stop. This may cause you to lose too much water.

Ketoacidosis (high ketones and acid in the blood) may occur while you are using this medicine. This can be life-threatening and requires immediate medical attention. Your doctor may give you insulin, fluid, and carbohydrate replacement to treat this condition. Tell your doctor right away if you have nausea, vomiting, trouble breathing, increased thirst or urination, or stomach pain.

Tell your doctor if you have bloody urine, decrease in how much or how often you urinate, painful or difficult urination, lower back or side pain, fever, chills, or swelling of the face, finger, or lower legs. These may be symptoms of a serious kidney problem.

Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine may affect the results of certain medical tests (eg, urine glucose tests may not be accurate). Also, you may need to stop taking this medicine at least 3 days before you have a surgery.

This medicine may cause vaginal yeast infections in women and yeast infections of the penis in men. This is more common in patients who have a history of genital yeast infections or in men who are not circumcised. Women may have a vaginal discharge, itching, or odor. Men may have redness, itching, swelling, or pain around the penis, or a discharge with a strong odor from the penis. Check with your doctor right away if you have any of these symptoms.

This medicine may increase risk of having urinary tract infections, including pyelonephritis or urosepsis. Check with your doctor right away if you have bladder pain, bloody or cloudy urine, difficult, burning, or painful urination, or lower back or side pain.

This medicine may cause a rare but serious bacterial infection, called necrotizing fasciitis of the perineum or Fournier's gangrene, which can cause damage to the tissue under the skin in the area between and around the anus and genitals (perineum). Fournier's gangrene may lead to hospitalization, multiple surgeries, or death. Check with your doctor right away if you have fever, unusual tiredness or weakness, or pain, tenderness, redness, or swelling of the area between and around your anus and genitals.

This medicine may cause hypoglycemia (low blood sugar). This is more common when this medicine is taken together with other diabetes medicines (eg, insulin, glipizide, glyburide). The symptoms of low blood sugar must be treated before they cause you to pass out. People feel different symptoms with low blood sugar. It is important that you learn which symptoms you usually have so you can treat it quickly. Some symptoms of low blood sugar include: behavior changes that are similar to being drunk, blurred vision, cold sweats, confusion, cool, pale skin, difficulty with thinking, drowsiness, excessive hunger, a fast heartbeat, headaches that continue, nausea, shakiness, slurred speech, or unusual tiredness or weakness. Talk to your doctor about how to treat low blood sugar.

Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your diabetes medicine, overeat or do not follow your diet plan, have a fever or infection, or do not exercise as much as usual. Some symptoms of high blood sugar include: blurred vision, drowsiness, dry mouth, flushed and dry skin, fruit-like breath odor, increased frequency and amount of urination, ketones in the urine, loss of appetite, nausea or vomiting, rapid and deep breathing, tiredness, or unusual thirst. If symptoms of high blood sugar occur, check your blood sugar level and call your doctor for instructions.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

How Can I Stay Healthy While Taking Xigduo XR?

Controlling your blood sugar as a person with type 2 diabetes can be a lifelong journey. While taking your medicine, you must routinely check your blood sugar. This helps you to notice how stable or fluctuating your readings may be.

Although diet and exercise may be necessary, speak to your healthcare provider before changing your eating pattern or starting any new exercise regimen to minimize your risk of any side effects. Consider working with a team that includes a registered dietitian (RD) or a registered dietitian nutritionist (RDN), particularly one who is a certified diabetes care and education specialist (CDCES).

CDCES RDs can help you explore your eating, movement, and medication habits, and more. They can help you build your toolkit and capacity to avoid spikes in blood sugar and help you feel better. Navigating blood sugar control and your eating patterns can be challenging, but you don't have to do this alone.

Speak to your healthcare provider about starting a vitamin B12 supplement, especially if you're on this drug long term. Do not start, adjust, or stop taking any medicine, including OTC vitamins, herbs, or supplements without speaking to your medical provider.
