Increased risk of metformin-associated lactic acidosis in renal or hepatic impairment, concomitant use of certain drugs (eg, cationic drugs), ≥65yrs of age, undergoing radiological contrast study, surgery and other procedures, hypoxic states, and excessive alcohol intake; discontinue if lactic acidosis is suspected. Discontinue at time of, or prior to intravascular iodinated contrast imaging in patients with eGFR <60mL/min/1.73m², history of hepatic impairment, alcoholism, heart failure, or will be given intra-arterial contrast; reevaluate eGFR 48hrs after procedure and restart therapy if renally stable. Correct volume depletion before initiating. Increased risk for volume depletion or hypotension in those with renal impairment (eGFR <60mL/min/1.73m²), elderly, or on loop diuretics. Assess volume status and renal function prior to initiation; monitor during therapy; more frequently in elderly. Assess for ketoacidosis in presence of signs/symptoms of metabolic acidosis, regardless of blood glucose levels; discontinue if suspected, evaluate and treat; consider risk factors before initiation (eg, pancreatic insulin deficiency, caloric restriction, alcohol abuse). Consider temporarily discontinuing prior to scheduled surgery (for ≥3 days) or other clinical situations (eg, prolonged fasting due to illness or post-surgery). Necrotizing fasciitis of the perineum (Fournier's gangrene); discontinue and treat immediately if suspected; use alternative antidiabetic. Increased risk of genital mycotic infections, UTIs (including urosepsis, pyelonephritis); monitor and treat as appropriate. Discontinue if hypersensitivity reaction occurs; treat promptly and monitor until resolve. Measure hematologic parameters annually and Vit. B₁₂ levels at 2–3 year intervals. Hepatic impairment, pregnancy (during 2^nd & 3^rd trimesters), nursing mothers: not recommended.
