Sitagliptin + Metformin hydrochloride
Jamesi Novum contains two different active substances called sitagliptin and metformin.
The combined action of these medicines leads to the normalization of blood sugar levels in adult patients with diabetes known as "type 2 diabetes". This medicine helps to increase the amount of insulin released after a meal and reduce the amount of sugar produced by the body. When taken in combination with diet and exercise, this medicine helps to reduce blood sugar levels. This medicine can be used alone or in combination with certain other anti-diabetic medicines (insulin, sulfonylurea derivatives, or glitazones). What is type 2 diabetes? In type 2 diabetes, the body does not produce enough insulin, and the insulin produced does not work as it should. The body may also produce too much sugar. If this happens, sugar (glucose) builds up in the blood. This can lead to serious health problems, such as heart disease, kidney disease, vision loss, and limb amputation.
Diabetic ketoacidosis is a disease in which substances called ketone bodies accumulate in the blood and can lead to a diabetic pre-coma state. Symptoms include: abdominal pain, rapid and deep breathing, drowsiness or unusual fruity odor from the mouth.
Do not take Jamesi Novum if you have any of the above contraindications. Consult your doctor to determine other methods of controlling diabetes. If in doubt, before taking Jamesi Novum, discuss it with your doctor, pharmacist, or nurse.
In patients taking sitagliptin + metformin, cases of pancreatitis (see section 4) have been reported. If you experience blisters on the skin, it may be a sign of a disease called pemphigoid blisters. Your doctor may advise you to stop taking Jamesi Novum.

The risk of lactic acidosis increases in cases of uncontrolled diabetes, severe infection, prolonged fasting or alcohol consumption, dehydration (see more detailed information below), liver disease, and any conditions in which a part of the body is not adequately supplied with oxygen (e.g., acute severe heart disease). If any of the above situations apply to you, consult your doctor for more detailed instructions.
