Instructions for use
Armacological action | A diabetes medicine that lowers fasting and postprandial blood sugar and glycated hemoglobin HbA1C. Partially blocks the production of glucose in the liver, as well as the absorption of eaten carbohydrates in the intestines. Increases tissue sensitivity to insulin. At the same time, it does not lower blood sugar excessively and does not cause hypoglycemia, unless the recommended dosage is exceeded. Helps people who are overweight lose weight. |
Pharmacokinetics | The active substance metformin is excreted from the body by the kidneys and urine. It is not metabolized by the liver, although it affects its function (see below). Does not accumulate in the body, except in people who have severe renal failure. Glucophage Long tablets are absorbed more slowly, but they last longer than the regular Glucophage drug. |
Indications for use | For patients with type 2 diabetes - in addition to diet and physical activity. Read more about the step-by-step treatment plan for type 2 diabetes.

- The initial dose of Glucophage is 500–850 mg in 2–3 daily doses. As blood glucose levels are examined and monitored, they are increased.
- The average daily dose of a hypoglycemic agent is 1,500–2,000 mg, which must be divided into 3 daily doses.

- In combination with Danazol, hyperglycemia develops; adjustment of the daily dosage is necessary when interacting with antipsychotics.
- The drugs Amiloride, Morphine, Quinidine, Ranitidine increase the concentration of metformin.
- Glucocorticosteroids provoke ketosis, reduce glucose tolerance, and increase its concentration in the bloodstream.
- β2-adrenergic receptor stimulants and Chlorpromazine in combination with metformin increase the concentration of glucose in the bloodstream.
- Injections of beta-agonists increase blood sugar concentrations, while ACE inhibitors and antihypertensive drugs, on the contrary, reduce them.
- Sulfonylurea derivatives, Acarbose, and salicylates, when used simultaneously with metformin, cause the development of hypoglycemia.

special instructions

- If surgery is necessary, stop using the tablets a couple of days before surgery.
- In patients with renal or liver failure or chronic alcoholism, the metformin component accumulates in the blood. This is how lactic acidosis progresses and the risk of death increases.
- When treating with Glucophage, it is necessary to monitor kidney function, and in case of glycemia, systematically measure blood glucose levels.
- When treating with this drug, a uniform supply of carbohydrates to the body is necessary. The calorie content of the daily menu is not less than 1,000 calories.
- The drug does not affect the speed of psychomotor reactions, therefore, during treatment it is allowed to drive a vehicle and engage in intellectual activities.
- Long-term use of a hypoglycemic agent contributes to the occurrence of hypovitaminosis B12, so a break is required between courses.
Overdose
When daily doses of Glucophage are systematically exceeded, lactic acidosis (lactic acidosis) develops . The patient's breathing quickens, pronounced signs of dyspepsia appear, dizziness worries, body temperature rises, confusion and coma are observed.
