How much a tablet of metformin lowers blood glucose is uncertain and may vary depending on individual differences, the dosage form of metformin, and the basal level of blood glucose.
Metformin is a biguanide glucose-lowering drug that is commonly used for type 2 diabetes. As each person has physical differences and different sensitivity to drugs, the dose and dosage form of one tablet of metformin are different, and the patients’ basal blood glucose levels are also different, so how much blood glucose is lowered by one tablet of metformin can’t be generalized.
Generally metformin can reduce blood glucose levels up to 1~2mmol/l, and can reduce glycated hemoglobin by nearly 1%. Metformin is mainly to improve insulin resistance, more effective for obese people. So it has a stronger hypoglycemic effect in patients who are obese and have significant insulin resistance.
Metformin may have nausea, vomiting, abdominal distension, abdominal pain and other digestive manifestations, as well as reduce vitamin B12 absorption, rare cause lactic acidosis and other side effects, the use of drugs should be noted.
Metformin should be taken under the supervision of a doctor and should not be taken on its own.
