Metformin is an oral antidiabetic medication that belongs to the biguanide class and used in the treatment of type 2 diabetes.
Metformin is an oral antidiabetic medication that belongs to the biguanide class. It is the first-line medicine used in the treatment of type 2 diabetes in overweight people. Metformin’s effectiveness is provided due to the ability of its active substances to inhibit the glyconeogenesis in the body. Metformin is also used in the treatment of polycystic ovary syndrome, and other diseases when insulin resistance may be an important factor. It reduces and normalizes body weight and improves fibrinolytic blood properties.
Take this medication exactly as your doctor has prescribed it. You must carefully follow all directions. To treat type 2 diabetes, metformin is initially used in dose of 500 mg taken twice daily or 850 mg taken once daily. The maximum tolerated daily dosage is 2550 mg divided into three smaller doses. If you use extended-release tablets, begin with a dose of 500 mg or 1000 mg per day. This medication is applied concurrently with meals.
Notify your doctor of any other medications that you might be taking besides this one. Taking this drug with a certain class of other medicines may result in increasing or decreasing the effects or alter them in either drug. Avoid drinking alcohol while being treated with this medicine. Apply metformin cautiously as it can cause a life threatening condition called lactic acidosis marked with following symptoms: weakness, severe somnolency, bradycardia, muscle pain, abdominal cramps, and difficulty breathing, a feeling that you may pass out.
This medicine is contraindicated in patients with hypersensitivity, diabetic precoma, ketoacidosis, gangrene, abscess, tinea pedis, acute infectious diseases, hepatic or renal insufficiency, acute myocardial infarction, respiratory failure, dehydration, chronic alcoholism, reduced-calorie diet (less than 1000 kcal/day), lactic acidosis, pregnancy, breastfeeding, intra-arterial or intravenous introduction of iodinated contrast agents.
Possible side effect
Potential side effect associated with metformin may involve: gastrointestinal upsets such as diarrhea, dyspepsia, abdominal cramps, nausea, retching, metallic taste, tympanism; hypovitaminosis; megaloblastic anemia; allergic reaction such as urticaria, swelling, itching and skin eruption. The most serious side effect of this dug is lactic acidosis. Metformin is also known to decrease the blood levels of thyroid-stimulating hormone in people with hypothyroidism and, in men, testosterone. Metformin can cause lowering of blood sugar levels in the blood, so be attentive if you experience hunger, irritability, drowsiness, migraine, weakness, tachycardia, tremors, excessive sweating, seizures. In this case you should always have a source of sugar near by.
A concomitant use of metformin with forms of sulphonyl carbamide and insulin can result in hypoglycemia. Ethanol increases a risk of lacticacidemia, therefore you should avoid consuming alcohol. Cimetidine (Tagamet) is able to reduce the elimination of metformin from the body which results in increasing of the metformin amount in the blood by 40%. This may intensify side effects of metformin such as lacticemia. Derivatives of MAO inhibitors, β2-adrenergic receptor agonists, angiotensin-converting-enzyme inhibitors, cyclophosphamide, clonbratum, oxytetracycline, non steroidal anti-inflammatory drugs can potentiate the hypoglycemic effect of metformin. Chlorpromazine neuroleptic inhibits insulin release which can lead to the increasing of the metformin dosage applied only in case of total controlling of glucose level in the blood serum.
