About Metform 500 Tablet 20's

Metform 500 Tablet 20's belongs to a group of anti-diabetic medicines called biguanides used in the treatment of diabetes. It helps to lower the increased blood glucose level in type 2 diabetes patients. Type 2 diabetes is a chronic or lifelong disorder that affects the way our body processes glucose. People with type 2 diabetes either do not produce enough insulin or the insulin produced is unable to perform its function in the body (insulin resistance). Middle-aged or older individuals are most likely to suffer from type 2 diabetes, so it is also known as adult-onset diabetes.

Metform 500 Tablet 20's is prescribed for the condition of type 2 diabetes when diet and exercise alone cannot control their blood sugar levels. It is the first-line therapy for patients with type 2 diabetes. Metform 500 Tablet 20's restores the body's response to insulin, decreases the amount of blood sugar produced by the liver, and delays the absorption of sugar by the stomach or intestines. Besides, Metform 500 Tablet 20's has off-label usage in women with polycystic ovary syndrome (PCOS) where it helps normalize the menstruation cycle by restoring the body's hormonal balance, lowers blood sugar levels, and stimulates ovulation. 

Usually, Metform 500 Tablet 20's does not cause very significant side effects. Common side effects include diarrhoea, nausea, vomiting, or a metallic taste in the mouth. In very rare cases, it may cause a condition known as lactic acidosis (too much lactic acid in the body) with symptoms like dizziness, drowsiness, muscle pain, etc. Your sugar level may go down while taking this medicine with heavy exercise, drinking excessive alcohol, or skipping meals. Talk to the doctor about any of the health conditions listed above that may require urgent medical treatment.

Metform 500 Tablet 20's works best when coupled with a healthy lifestyle like losing weight if you are overweight (BMI >25), eating fewer calories (low fat and sugary food), and being more physically active (at least 150 min of activity every week).
