Read this package insert carefully before taking this medicine, as it contains important information for you.

• Keep this package insert, as you may need to refer to it again.
• If you have any questions, consult your doctor, pharmacist, or nurse.
• This medicine has been prescribed for you only, and you should not give it to others who have the same symptoms as you, as it may harm them.

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

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

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

What is type 2 diabetes?

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

Do not take Disit

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

Warnings and precautions

Consult your doctor or pharmacist before starting to take this medication.

Cases of pancreatitis have been reported in patients treated with sitagliptin (see section 4).

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

Inform your doctor if you have or have had:

• pancreatitis (such as pancreatitis)
• gallstones, alcohol addiction, or very high levels of triglycerides in the blood (a type of fat). 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 problems you currently have or have had in the past
• an allergic reaction to sitagliptin (see section 4).

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