1. What is Sytena and what is it used for

Sytena contains the active substance sitagliptin, which belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors), which reduce blood sugar levels in adults with type 2 diabetes.
This medicine helps to increase the amount of insulin released after a meal and decrease the amount of sugar produced by the body.
Your doctor has prescribed this medicine to reduce high blood sugar levels caused by type 2 diabetes. This medicine can be used alone or in combination with other medicines (insulin, metformin, sulfonylurea derivatives, or glitazones) that lower blood sugar levels, which may already be taken for diabetes, along with diet and exercise.
What is type 2 diabetes?
Type 2 diabetes is a disease in which 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, loss of vision, and limb amputation.

2. Important information before taking Sytena

When not to take Sytena

• if you are allergic to sitagliptin or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

In patients taking Sytena, cases of pancreatitis (see section 4) have been reported.
If you develop blisters on your skin, it may be a sign of a disease called bullous pemphigoid. Your doctor may advise you to stop taking sitagliptin.
Tell your doctor if you have or have had:

• pancreatic disease (e.g., pancreatitis);
• gallstones, alcohol dependence, or very high levels of triglycerides (a type of fat) in the blood. In these situations, the risk of pancreatitis (see section 4) may increase;
• type 1 diabetes;
• diabetic ketoacidosis (a complication of diabetes characterized by high blood sugar levels, rapid weight loss, nausea, or vomiting);
• any kidney disease that has occurred in the past or is present;
• an allergic reaction to sitagliptin (see section 4).

Since this medicine does not work when blood sugar levels are low, it is unlikely to cause low blood sugar levels. However, if this medicine is taken with a sulfonylurea derivative or insulin, low blood sugar levels (hypoglycemia) may occur. Your doctor may reduce the dose of the sulfonylurea derivative or insulin.
