A: Metformin is an oral diabetes medication that helps control blood glucose (sugar) levels. It is used to treat type 2 diabetes, either alone or in combination with insulin or other medications. Common side effects include headache, weakness, mild nausea, vomiting, diarrhea, gas, and stomach pain.
Metformin has many drug-disease interactions that can increase the risk of MALA. Metformin may increase lactic acid production from the splanchnic tissues slightly, but MALA occurs in the setting of comorbid diseases that increase systemic levels of lactic acid or reduce elimination of metformin.
