Ertugliflozin and metformin (Oral)
Medically reviewed by Drugs.com. Last updated on Apr 18, 2022.
Death, hypothermia, hypotension, and resistant bradyarrhythmias have been reported due to metformin-associated lactic acidosis. Onset may be subtle and include nonspecific symptoms such as malaise, myalgia, respiratory distress, somnolence, and abdominal distress; laboratory abnormalities include low pH, increased anion gap and elevated blood lactate. The risk of lactic acidosis increases with renal or hepatic impairment, aged 65 years or older, having a radiological study with contrast, surgery, or other procedures, hypoxic states, and excessive alcohol intake. If lactic acidosis is suspected, ertugliflozin and metformin hydrochloride should be discontinued, supportive measures started in a hospital setting. Prompt hemodialysis is recommended .

Uses for ertugliflozin and metformin
Ertugliflozin and metformin combination is used with proper diet and exercise to treat high blood sugar levels caused by type 2 diabetes in patients who are already using ertugliflozin and metformin for treatment or who do not have control of their blood sugar on ertugliflozin or metformin alone.
Ertugliflozin works in the kidneys to prevent absorption of glucose (blood sugar). This helps lower the blood sugar level. Metformin reduces the absorption of sugar from the stomach, reduces the release of stored sugar from the liver, and helps your body use sugar better. Ertugliflozin and metformin does not help patients who have insulin-dependent or type 1 diabetes. Type 1 diabetic patients must use insulin injections.
Ertugliflozin and metformin is available only with your doctor's prescription.
Before using ertugliflozin and metformin
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For ertugliflozin and metformin, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to ertugliflozin and metformin or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of ertugliflozin and metformin combination in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of ertugliflozin and metformin combination in the elderly. However, elderly patients are more likely to have kidney problems, which may require caution and an adjustment in the dose for patients receiving ertugliflozin and metformin combination.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Using ertugliflozin and metformin during the second and later part of a pregnancy can harm your unborn baby. If you think you have become pregnant while using ertugliflozin and metformin, tell your doctor right away.
Under certain conditions, too much metformin can cause a serious condition called lactic acidosis. It usually occurs when other serious health problems are present, including 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. If you have more than one of these symptoms together, you should get immediate emergency medical help.
Dizziness, lightheadedness, or fainting may occur with ertugliflozin and metformin. This is more common if you have kidney disease, low blood pressure, or if you are taking a diuretic (water pill). Drinking 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 ertugliflozin and metformin. 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.
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.
Ertugliflozin and metformin may increase your 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.
Ertugliflozin and metformin may increase your risk of having lower leg or foot amputation (leg removal surgery). Check with your doctor right away if you have pain, tenderness, sores or ulcers, or infections on your leg or foot.
Ertugliflozin and metformin can cause hypoglycemia (low blood sugar). However, low blood sugar can occur if you delay or miss a meal or snack, exercise more than usual, drink alcohol, cannot eat because of nausea or vomiting, or take certain medicines. Low blood sugar must be treated before it causes you to pass out (unconsciousness). People feel different symptoms of low blood sugar. 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 the best way 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. High blood sugar can be very serious and must be treated right away.Some symptoms of high blood sugar include blurred vision, drowsiness, dry mouth, flushed and dry skin, a 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. Talk to your doctor about the best way to treat high blood sugar.
Ertugliflozin and metformin 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.
Ertugliflozin and metformin 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.
Ertugliflozin and metformin 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.
Let your doctor or dentist know you are using ertugliflozin and metformin. Your doctor may advise you to stop using ertugliflozin and metformin at least 4 days before you have major surgery or diagnostic tests, especially tests that use a contrast dye.
Make sure any doctor or dentist who treats you knows that you are using ertugliflozin and metformin. Ertugliflozin and metformin may affect the results of certain medical tests (eg, urine glucose tests may not be accurate).
Do not drink a lot of alcohol while you are using ertugliflozin and metformin. Heavy alcohol use can increase your risk for lactic acidosis.
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 you have diabetes with a list of all your medicines.
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.
