This drug is applicable for patients of various ages who need blood sugar management. It helps safely control blood sugar and assists in diabetes treatment.

This drug may cause severe lactic acidosis or hypoglycemia, so it should not be used in patients with severely impaired heart or kidney function, acute infections, or dehydration. It should also not be administered to patients with acute heart failure, acute myocardial infarction, those undergoing radiographic iodine contrast examinations, or those allergic to this drug or biguanide medications. The use of this drug should be avoided in cases of placental insufficiency or risk of preeclampsia during pregnancy, and patients scheduled for surgery should discontinue this medication 48 hours prior to the procedure. This drug may accumulate depending on kidney function, increasing the risk of lactic acidosis, thus regular monitoring of kidney function should be conducted before and during treatment. Careful use is required when dietary intake is irregular or insufficient, when engaging in intense exercise, or when other medications are taken. While taking this medication, gastrointestinal disturbances, metallic taste, rash, anemia, liver function abnormalities, and hypoglycemia may occur, so consultation with a healthcare provider is advised if symptoms arise. Alcohol consumption may increase the risk of lactic acidosis as a side effect of this drug, so it is important to avoid excessive drinking during treatment. Particularly in elderly patients or those with reduced kidney function, adjustments to the dosage and regular monitoring of kidney function are necessary. This medication crosses the placenta during pregnancy; hence it should be used cautiously based on a physician's judgment during preconception, pregnancy, and after delivery. For breastfeeding individuals, consideration should be given to stopping either breastfeeding or the treatment. When used in conjunction with other drugs that may enhance or decrease blood sugar-lowering effects, blood sugar status should be closely monitored, and in acute crises, treatment should be discontinued, and appropriate care should be sought. Finally, it is crucial to regularly monitor blood sugar and blood tests and kidney function to closely observe the treatment effects and any side effects during the use of this drug.
