A 54-year-old woman with type 2 diabetes mellitus, hypertension, and peripheral vascular disease developed life-threatening lactic acidosis during treatment with metformin for type 2 diabetes. The woman received metformin at 1000 mg orally twice a day for type 2 diabetes. She presented to our emergency department with a 3-day history of severe watery diarrhea, nausea, and vomiting. Her grandson whom she cared for had gastroenteritis several days prior to the onset of her symptoms. She was confused and hypotensive with a blood pressure of 70/39 mm Hg. Upon arrival in the emergency department, she became unresponsive and experienced a pulseless electrical activity cardiac arrest. Her initial laboratory findings were remarkable with an arterial blood gas p H 6.57, HCO 2 m Eq/L, anion gap 30 mmol/L, and lactate 16.3 mmol/L. After resuscitation, her severe acidemia persisted despite aggressive intervention with volume resuscitation and vasopressors, leading to the initiation of renal replacement therapy. After multiple dialysis treatments, her severe acidemia resolved. amoxicillin candida Metformin is a useful anti-hyperglycaemic agent but significant mortality is associated with drug-induced lactic acidosis. Significant renal and hepatic disease, alcoholism and conditions associated with hypoxia (eg. cardiac and pulmonary disease, surgery) are contraindications to the use of metformin. Other risk factors for metformin-induced lactic acidosis are sepsis, dehydration, high dosages and increasing age. Metformin remains a major reported cause of drug-associated mortality in New Zealand. Of the 12 cases of lactic acidosis associated with metformin reported to CARM since 1977, 2 occurred in the last year and 8 cases had a fatal outcome. Metformin is a useful therapeutic agent for obese non-insulin dependent diabetics and those whose glycaemia cannot be controlled by sulphonylurea monotherapy. Buy generic viagra 50mg HISTORICAL PERSPECTIVE. Despite these proven benefits, metformin remains contraindicated in a large segment of the type 2 diabetic population, largely because of concerns over the rare adverse effect of lactic acidosis. prednisolone side effects in children In 1995, the oral antihyperglycemic agent, metformin, was introduced in the United States for treating diabetes mellitus. Rare cases of metformin-associated. Peer Reviewed. LEARNING OBJECTIVES. 1. What is metformin-associated lactic acidosis? 2. How does severe acidemia lead to acute kidney. For adult patients with type 2 diabetes mellitus: Janumet is indicated as an adjunct to diet and exercise to improve glycaemic control in patients inadequately controlled on their maximal tolerated dose of metformin alone or those already being treated with the combination of sitagliptin and metformin. Janumet is indicated in combination with a sulphonylurea (i.e., triple combination therapy) as an adjunct to diet and exercise in patients inadequately controlled on their maximal tolerated dose of metformin and a sulphonylurea. Janumet is indicated as triple combination therapy with a peroxisome proliferator-activated receptor gamma (PPARγ) agonist (i.e., a thiazolidinedione) as an adjunct to diet and exercise in patients inadequately controlled on their maximal tolerated dose of metformin and a PPARγ agonist. Janumet is also indicated as add-on to insulin (i.e., triple combination therapy) as an adjunct to diet and exercise to improve glycaemic control in patients when stable dose of insulin and metformin alone do not provide adequate glycaemic control. The dose of antihyperglycaemic therapy with Janumet should be individualised on the basis of the patient's current regimen, effectiveness, and tolerability while not exceeding the maximum recommended daily dose of 100 mg sitagliptin. Adults with normal renal function (GFR ≥ 90 m L/min) For patients not adequately controlled on metformin alone, the usual starting dose should provide sitagliptin dosed as 50 mg twice daily (100 mg total daily dose) plus the dose of metformin already being taken. The dose should provide sitagliptin dosed as 50 mg twice daily (100 mg total daily dose) and a dose of metformin similar to the dose already being taken. Metformin is an oral hypoglycemic drug that has long been employed in the treatment of type 2 diabetes; it is particularly widely prescribed for those diabetics who are obese. Very rarely, metformin use results in severe lactic acidosis, most often occurring in patients with reduced renal function. Although a very rare adverse effect, metformin-associated lactic acidosis (MALA) is significant because it has a high (30-50 %) mortality rate. Lactic acidosis (unrelated to metformin) is a relatively common occurrence among the critically ill and usually arises as a result of tissue hypoxia consequent on the inadequate perfusion associated with clinical shock. The list of severe acute illnesses/conditions that can result in lactic acidosis is long and includes severe sepsis (septic shock), severe trauma (hemorrhagic shock), anaphylactic shock, cardiac arrest and acute liver failure. In all of these cases prognosis is predicted by the severity of the lactic acidosis; the higher the peak serum lactate and the lower the blood p H falls, the greater is the risk of not surviving these acute illnesses. Although metformin is a very rare cause of lactic acidosis, it is almost invariably very severe.
