Impaired renal functions and situations that could lead thereto (severe infections, surgery, intravenous pyelography). sertraline while pregnant The biguanide metformin (dimethylbiguanide) was initially introduced for use in the treatment of type 2 diabetes mellitus in the late 1950s. Today this drug is considered to be the first-choice agent and the “gold standard” for most people with type 2 diabetes. It has been estimated that the annual number of people receiving prescriptions for metformin worldwide is more than 120 million. The efficacy and benefits of metformin treatment in type 2 diabetes have been confirmed by large-scale studies and recognized by many consensus statements. Still, a large list of contraindications may increase the incidence of serious adverse effects, which precludes many patients from taking metformin. Three particular contraindications to the use of metformin have been suggested. They include renal impairment with elevated serum creatine levels ( more than 136 mmol/l in men and 124 mmol/l in women) or abnormal creatinine clearance, congestive heart failure requiring pharmacologic treatment and advanced age (more than 80 years of age).

Metformin is an effective anti-hyperglycaemic and cardioprotective agent, but a long list of contraindications precludes millions of patients with type 2 diabetes from using it. This is largely due to the historical experience of lactic acidosis with phenformin, despite the fact that metformin does not predispose to this when compared with other therapies. Contraindications such as old age, renal impairment and cardiac insufficiency are increasingly disregarded in clinical practice, yet there is no evidence that the incidence of lactic acidosis has changed. Metformin has been shown to improve metabolic control without causing lactic acidosis in elderly patients with multiple comorbidities, including explicit contraindications, and its use in patients with type 2 diabetes over the age of 70 with mild renal impairment did not produce a clinically relevant increase in plasma lactate. There is no correlation between levels of metformin and lactate in patients with lactic acidosis, and its prognosis is mainly related to the causal hypoxic underlying disease and comorbidities. These findings raise doubts about the pathogenetic significance of metformin in lactic acidosis. We propose that advanced age per se, mild renal impairment and compensated heart failure can no longer be upheld as contraindications for metformin.
