Discontinue if lactic acidosis or pancreatitis is suspected; any condition characterized by hypoxemia eg, acute CHF, MI. Temporarily suspend treatment for any surgical procedure. Metformin may decrease vit B12 levels. Periodically measure blood glucose & HbA1c levels. Monitor hematologic parameters & renal function initially & at least annually thereafter. Patients w/ adrenal or pituitary insufficiency or alcohol intoxication are susceptible to hypoglycemic effects. Promptly evaluate patients w/ previously well-controlled type 2 diabetes who develop ketoacidosis or lactic acidosis. Avoid in patients w/ clinical or laboratory incidence of hepatic disease. Renal dysfunction. Pregnancy & lactation. Childn. Debilitated, malnourished or elderly patients.

Headache; diarrhea, nausea, abdominal pain, vomiting, acute pancreatitis, including fatal & nonfatal hemorrhagic & necrotizing pancreatitis; angioedema, cutaneous vasculitis, exfoliative skin conditions including Stevens-Johnson syndrome, hypersensitivity; hypoglycemia; upper resp tract infection; hepatic enzyme elevations.
Drug Interactions
May increase AUC & Cmax of digoxin. Closely monitor to maintain adequate glycemic control of patients concomitantly taking drugs that produce hyperglycemia eg, Ca channel blockers, corticosteroids, diuretics [eg, thiazides], estrogen, hormonal contraceptives, INH, nicotinic acid, phenothiazines, phenytoin, sympathomimetics, thyroid products. May decrease AUC and Cmax of glyburide. Increased risk of hypoglycemia w/ meglitinides [eg, nateglinide, repaglinide], & sulfonylureas. Metformin: Potentiated hypoglycemic effects & effects on lactic acidosis w/ alcohol. May compete for renal tubular transport w/ cationic drugs  eg, amiloride, digoxin, morphine, procainamide, quinidine, ranitidine, triamterene, trimethoprim & vancomycin. Increased plasma levels w/ cimetidine. Decreased extent of & slightly delayed absorption w/ food. Increased AUC & Cmax w/ furosemide, decreased AUC & Cmax of furosemide. Increased AUC & Cmax w/ nifedipine. Decreased GFR & increased risk of lactic acidosis w/ NSAIDs eg, indomethacin & rofecoxib. Increased risk of lactic acidosis w/ parenteral iodinated contrast media. Sitagliptin: Increased AUC & Cmax w/ cyclosporine.
