1. What is Sitagliptina Cinfa and what is it used for

This medicine contains the active substance sitagliptin, which belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors) that reduce blood sugar levels in adult patients with type 2 diabetes mellitus.

This medicine helps to increase the amount of insulin produced after a meal and decreases the amount of sugar produced by the body.

Your doctor has prescribed this medicine to help you reduce your blood sugar level, which is too high due to your type 2 diabetes. This medicine can be used alone or in combination with other medicines (insulin, metformin, sulfonylureas, or glitazones) that reduce blood sugar levels, which you may already be taking for your diabetes, along with your diet and exercise program.

What is type 2 diabetes?

Type 2 diabetes is a disease where your body does not produce enough insulin, and the insulin it produces does not work as well as it should. Your body may also produce too much sugar. When this happens, sugar (glucose) builds up in the blood. This can cause serious medical problems, such as heart disease, kidney disease, blindness, and amputation.

2. What you need to know before you take Sitagliptina Cinfa

Do not take Sitagliptina Cinfa

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

Warnings and precautions

Consult your doctor or pharmacist before taking this medicine.

There have been reports of pancreatitis (inflammation of the pancreas) in patients treated with sitagliptin (see section 4).

If you notice blisters on your skin, it may be a sign of a disease called bullous pemphigoid. Your doctor may ask you to stop taking sitagliptina.

Tell your doctor if you have or have had:

• a pancreatic disease (such as pancreatitis)
• gallstones, alcohol addiction, or very high levels of triglycerides (a type of fat) in the blood. These medical conditions may increase your risk of developing pancreatitis (see section 4)
• type 1 diabetes
• diabetic ketoacidosis (a complication of diabetes that causes high blood sugar levels, rapid weight loss, nausea, or vomiting)
• any kidney problem you have now or have had in the past - an allergic reaction to sitagliptina (see section 4).

It is unlikely that this medicine will cause low blood sugar because it does not work when blood sugar levels are low. However, when this medicine is used in combination with a medicine that contains a sulfonylurea or with insulin, low blood sugar (hypoglycemia) may occur. Your doctor may reduce the dose of your sulfonylurea or insulin medicine.
