Renal Dose
Renal impairment
Obtain eGFR before starting metformin
eGFR <30 mL/min/1.73 m²: Contraindicated
eGFR 30-45 mL/min/1.73 m²: Not recommended to initiate treatment
Monitor eGFR at least annually or more often for those at risk for renal impairment (eg, elderly)
If eGFR falls below 45mL/min/1.73 m² while taking metformin, risks and benefits of continuing therapy should be evaluated
If eGFR falls below 30 mL/min/1.73 m²: while taking metformin, discontinue the drug
Administration
Should be taken with food.
Contra Indications
Acute or chronic metabolic acidosis with or without coma (including diabetic ketoacidosis). Renal failure, severe renal or hepatic impairment, acute conditions which may affect renal function e.g. dehydration, severe infection or shock. Cardiac failure, CHF, IDDM, severe impairment of thyroid function; acute or chronic alcoholism. Acute or chronic diseases which may cause tissue hypoxia e.g. cardiac or respiratory failure, recent MI or shock. Pregnancy, lactation.
Precautions
Caution when used in patients with CHF especially in those with unstable or acute heart failure. Risk of lactic acid accumulation increases with the degree of renal impairment. May need to discontinue treatment in patients with stress-related states e.g. fever, trauma, infection or surgery. Metformin should be temporarily discontinued for 48 hr in patients undergoing radiologic studies involving intravascular admin of iodinated contrast materials. Elderly. Monitor renal function regularly. Because of possibility of hypoglycemia in combination therapy with a sulphonylurea or insulin, diabetic control should be monitored by blood sugar readings.
Lactation: Enters breast milk; not recommended
Pregnancy-Lactation
Interactions
Additive effect w/ sulfonylureas. Thiazide diuretics, corticosteroids, phenothiazines, OC, sympathomimetics, niacin, Ca channel blockers and isoniazid may exacerbate loss of glycaemic control. ACE inhibitors may reduce fasting blood glucose concentrations. May increase serum level w/ cimetidine.
Potentially Fatal: Concurrent use w/ iodinated contrast agents may increase the risk of metformin-induced lactic acidosis.
Adverse Effects
Side effects of Metformin Hydrochloride :
Anorexia, nausea, vomiting, diarrhoea, wt loss, flatulence, occasional metallic taste; weakness; hypoglycaemia; rash, malabsorption of vit B12. Chest discomfort, flushing, palpitation, chills, headache, lightheadedness, indigestion, abdominal discomfort.
Potentially Fatal: Lactic acidosis in presence of renal failure and alcoholism. Patients may experience a metallic taste and there may be weight loss, which in some diabetics could be an advantage.
Mechanism of Action
Metformin is a biguanide w/ antihyperglycaemic effects, lowering both basal and postprandial plasma glucose. It decreases hepatic glucose production by inhibiting gluconeogenesis and glycogenolysis; delays intestinal absorption of glucose; and enhances insulin sensitivity by increasing peripheral glucose uptake and utilisation.
