High-Risk Groups (Elderly, Pregnant, Indigenous Health Considerations)

Metformin, a widely used medication for type 2 diabetes, has critical warnings, particularly concerning specific high-risk groups. Elderly patients may be at an increased risk for lactic acidosis, a serious condition that can occur when there is a buildup of lactic acid in the bloodstream. Due to this risk, close monitoring of renal function is paramount to ensure that elderly individuals do not face complications. Pregnant women also require careful consideration when prescribed Metformin, as glycemic control during pregnancy is vital for maternal and fetal wellbeing. There are implications for prescribing within Indigenous health considerations too. Indigenous populations may have distinct metabolic profiles, necessitating a personalized approach to treatment guidelines. Tailoring treatment ensures that all individuals, regardless of background or age, receive optimal care while minimizing risks associated with this medication.
