METFORMIN HYDROCHLORIDE

5 WARNINGS AND PRECAUTIONS Lactic Acidosis: See boxed warning
2 ) Hypoglycemia with Concomitant Use with Insulin and Insulin Secretagogues: Increased risk of hypoglycemia when used in combination with insulin and/or an insulin secretagogue
1 Lactic Acidosis There have been postmarketing cases of metformin-associated lactic acidosis, including fatal cases
Metformin decreases liver uptake of lactate increasing lactate blood levels which may increase the risk of lactic acidosis, especially in patients at risk

5 WARNINGS AND PRECAUTIONS Congestive heart failure: Fluid retention may occur and can exacerbate or lead to congestive heart failure
Combination use with insulin and use in congestive heart failure NYHA Class I and II may increase risk
3 ) Hypoglycemia: Consider a lower dose of insulin or insulin secretagogue to reduce risk of hypoglycemia when used in combination with pioglitazone and metformin hydrochloride
4 ) Hepatic effects: Postmarketing reports of hepatic failure, sometimes fatal
