How ISTamet Products work

Sitagliptin + Metformin is a combination of two medicines: sitagliptin and metformin. Sitagliptin help your pancreas produce more insulin, facilitate effective use of insulin by the body, and reduce excess sugar that your liver makes. Metformin is a biguanide which lowers glucose production in the liver, delays glucose absorption from intestines and increases the body's sensitivity to insulin. Together, they provide better control of blood sugar.

Q. Can the use of ISTamet 50mg/500mg Tablet lead to lactic acidosis?

Yes, the use of ISTamet 50mg/500mg Tablet can lead to lactic acidosis. It is a medical emergency caused by the increased levels of lactic acid in the blood. It is also known as MALA (metformin-associated lactic acidosis). It is a rare side effect associated with the use of metformin. Therefore, it is avoided in patients with underlying kidney disease, elderly patients, or those who take large amounts of alcohol. Symptoms of lactic acidosis may include muscle pain or weakness, dizziness, tiredness, a feeling of cold in arms and legs, difficulty in breathing, nausea, vomiting, stomach pain, or a slow heart rate.
