Metformin is usually the first medicine prescribed for type 2 diabetes. It reduces blood glucose by decreasing the production of glucose by the liver and making the body’s cells more responsive to insulin.
It is generally well tolerated, with mild side effects of nausea, anorexia and diarrhoea.
Unlike other oral medicines, metformin does not cause weight gain. It also has a beneficial effect on outcomes in diabetics with heart disease.
It is usually not prescribed if there is impaired kidney function, liver cirrhosis, heart failure, chronic respiratory disease, vascular disease, severe infection, terminal ileum disease or previous gastrectomy.
If you are on Metformin and still not able to manage your diabetes, perhaps you should consult a Physician for other options available.
