Risk may increase with significant kidney impairment, severe dehydration, serious infection, hypoxia, certain heart or liver conditions, and excessive alcohol consumption. ### Vitamin B12 Deficiency Long-term metformin therapy can reduce vitamin B12 levels. Your healthcare professional may recommend periodic vitamin B12 monitoring, especially if you develop anemia, numbness, tingling, or other symptoms suggestive of deficiency. ### Alcohol Avoid excessive alcohol consumption because it can increase the risk of lactic acidosis and may interfere with blood glucose control. ### Surgery and Contrast Procedures Metformin may need to be temporarily discontinued around certain surgical procedures or imaging tests involving **iodinated contrast**, depending on kidney function and the clinical situation. Follow your doctor's instructions. ### Pregnancy and Breastfeeding Tell your healthcare professional if you are pregnant, planning pregnancy, or breastfeeding. Diabetes treatment may need to be reviewed during pregnancy. ## DRUG INTERACTIONS Metformin may interact with: * **Iodinated contrast media** — may require temporary interruption of metformin in certain circumstances. * **Alcohol** — excessive intake increases the risk of lactic acidosis. * **Cimetidine and certain other medicines** — may affect metformin elimination. * Medicines that can impair kidney function — may increase metformin-related risks. * **Corticosteroids** — may increase blood glucose. * Diuretics — may affect blood glucose and kidney function. * Other diabetes medicines or insulin — may increase the risk of hypoglycemia when used in combination. * Certain thyroid medicines and other medicines that can affect blood glucose.
