Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. Symptoms included malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Laboratory abnormalities included elevated blood lactate levels, anion gap acidosis, increased lactate/pyruvate ratio, and metformin plasma levels generally greater than 5 mcg/mL. Risk factors include renal impairment, concomitant use of certain drugs (eg, carbonic anhydrase inhibitors such as topiramate), age 65 years or older, radiological study with contrast, surgery and other procedures, hypoxic states, excessive alcohol intake, and hepatic impairment. If lactic acidosis is suspected, discontinue empagliflozin/metformin hydrochloride and institute general supportive measures in a hospital setting .

Uses For Synjardy
Empagliflozin and metformin combination is used with proper diet and exercise to treat high blood sugar levels caused by type 2 diabetes. It is also used to lower the risk of death in patients with type 2 diabetes and heart or blood vessel disease.
Empagliflozin works in the kidney 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. It does not help patients who have insulin-dependent or type 1 diabetes. Type 1 diabetic patients must use insulin injections.
This medicine is available only with your doctor's prescription.

Precautions While Using Synjardy
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.
Under certain conditions, too much metformin can cause a serious condition called lactic acidosis. Lactic acidosis usually occurs when other serious health problems are present, such as a heart attack or kidney failure. The symptoms of lactic acidosis include: abdominal or stomach discomfort, decreased appetite, diarrhea, fast or shallow breathing, a general feeling of discomfort, muscle pain or cramping, 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 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.
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.
Let your doctor or dentist know you are taking this medicine. Your doctor may advise you to stop taking this medicine 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 this medicine. This medicine may affect the results of certain medical tests (eg, urine glucose tests may not be accurate).
This medicine 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. 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. It is important that you learn which symptoms you have in order to treat it quickly. Talk to your doctor about the best way to treat high blood sugar.
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 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.
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.
This medicine may make you dizzy. Do not drive or do anything else that could be dangerous until you know how this medicine affects you. Stand up slowly if you feel dizzy.
Limit the amount of alcohol you drink while you are using this medicine. Heavy alcohol use can increase your chances of serious side effects.
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.
