Metformin

Prescription vs.OTC: Prescription by Doctor required
Last Updated: November 30, 2019

Metformin is a drug that helps maintain balanced blood sugar levels in the body. It is used to treat Type 2 diabetes, heart disorders and polycystic ovary syndrome.

Metformin works by decreasing the amount of glucose produced by the liver. It suppresses the quantity of glucose that the liver releases in the body. Thus, it lowers the blood sugar levels in the body of a patient suffering from Type 2 diabetes. Metformin also increases your sensitivity to insulin, enabling your body to absorb larger quantities of glucose. This drug is available in oral solution or even tablet form.

Metformin is an oral drug that is used to control and balance blood sugar levels. This medication is used in the treatment of conditions such as type 2 diabetes, obesity, cardiovascular diseases, hypertension and polycystic ovarian syndrome. If you do not manage the condition of diabetes, it can result in kidney failure, obesity and heart disorders. Therefore, Metformin helps keep your blood sugar levels low and your diabetes in check.

Metformin does not increase the amount of insulin in the body; instead, it decreases the production of sugar. The liver of patients, who suffer from type 2 diabetes, produces thrice the amount of glucose and their bodies do not have the capacity to absorb these large amounts of glucose. Metformin is effective in lowering the amount of glucose that the liver releases. It also decreases your appetite and increases your body’s sensitivity to insulin, thus, reducing the amount of glucose that is absorbed by your blood. An increased sensitivity to insulin also lowers your levels of cholesterol and helps you to lose weight.

Metformin is available in the form of tablets as well as oral solutions. The dosage that the doctor recommends for your treatment will be based on your age, your condition, the severity of your condition and the other medications you are currently taking. You should follow the course of this treatment until it is completed, and do not skip out on a dose.

In some cases, it is advisable for the patients of certain conditions to avoid taking this medication. You should inform your doctor before taking this medicine, if you suffer from conditions like liver disease, kidney disorders, heart disease, allergies and diabetic ketoacidosis. Pregnant women, women who are breast-feeding their infants and children below ten years should not take this medicine.

The common side effects of Metformin include diarrhea, dizziness, headaches, vomiting and stomach cramps. Consuming this medicine with food can lower your risk of developing the side effects. One rare yet major side effect of Metformin is lactic acidosis. It is build up of lactic acid in the blood, which can be fatal. This side effect causes symptoms such as muscle weakness, stomach aches, nausea, irregular heartbeat, difficulty breathing, cold or numb sensation in the arms and legs. You should seek emergency medical aid, if you detect any of these symptoms. It is important to avoid drinking alcohol while taking this medicine, since it can increase your risk of developing lactic acidosis.
