Discontinue if ketoacidosis, necrotizing fasciitis is suspected; at the time of surgery under general, spinal or epidural anaesth & may be restarted no earlier than 48 hr following surgery or resumption of oral nutrition. Consider temporary discontinuation for at least 3 days prior to surgery in patients who will undergo scheduled surgery; in clinical situations known to predispose to ketoacidosis; present conditions that alter renal function. Consider temporary treatment interruption until fluid loss is corrected; patients w/ complicated UTI. Temporarily discontinue metformin if dehydration (severe diarrhea or vomiting, fever or reduced fluid intake) occurs. Discontinue metformin in suspected symptoms of lactic acidosis; prior to iodinated contrast media administration or at the time of imaging procedure & not restarted until at least 48 hr provided that renal function has been re-evaluated & stable. W/draw treatment immediately if signs & symptoms suggestive of mitochondrial encephalopathy w/ lactic acidosis & stroke-like episodes (MELAS) syndrome & maternal inherited diabetes & deafness (MIDD) occur after metformin intake & perform prompt diagnostic evaluation. Not to be used in patients w/ type 1 diabetes; ketoacidosis; severe infection & accident. Not recommended in patients w/ known mitochondrial diseases eg, MELAS syndrome & MIDD. Diabetic ketoacidosis; lactic acidosis. Intravascular administration of iodinated contrast agents may lead to contrast induced nephropathy, resulting in metformin accumulation & increased risk of lactic acidosis. Complicated UTI including pyelonephritis & urosepsis. Bacterial & fungal infection on genital area & urinary tract. Patients on very low carbohydrate diet, w/ acute illness, pancreatic disorders suggesting insulin deficiency (eg, type 1 diabetes, history of pancreatitis or pancreatic surgery), insulin dose reduction (including insulin pump failure), alcohol abuse, severe dehydration, & history of ketoacidosis; heart failure; for whom empagliflozin-induced drop in BP could pose a risk eg, patients w/ known CV disease, on antihypertensive therapy w/ history of hypotension or ≥75 yr. Assess patients for ketoacidosis immediately if symptoms occur regardless of blood glucose level; estimated GFR before treatment initiation & regularly (at least annually) thereafter. Monitor ketones; cardiac & renal (every 3-6 mth in patients at increased risk of renal impairment progression & elderly) function in patients w/ stable chronic heart failure; vol status (eg, physical exam, BP measurements, lab tests including haematocrit) & electrolytes in case of conditions leading to fluid loss (eg, GI illness); vit B
12 serum levels in case of suspicion of deficiency (eg, anaemia or neuropathy). Evaluate treated patients for necrotizing fasciitis who present w/ pain or tenderness, erythema, genital or perineal swelling, fever, malaise. Ensure risk factors for ketoacidosis are resolved prior to restarting treatment. Concomitant use w/ medicinal products that can acutely impair renal function eg, antihypertensives, diuretics & NSAIDs; can cause lactic acidosis. Not to be taken w/ alcohol. Avoid use during pregnancy. Discontinue breastfeeding during treatment. Childn <10 yr. Elderly ≥75 yr (increased risk of vol depletion).
