1. Contents of the pack and additional information

Ristaben 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, which is too high due to your type 2 diabetes. This medication can be used alone or in combination with other medications (insulin, metformin, sulfonylureas, or thiazolidinediones) that reduce blood sugar, and that 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 produces not working 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 Ristaben

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

Warnings and precautions

Cases of pancreatitis have been reported in patients treated with Ristaben (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 Ristaben.

Inform your doctor if you have or have had:

• pancreatitis (such as pancreatitis)

• gallstones, alcohol addiction, or very high levels of triglycerides in your 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 problems you currently have or have had in the past

• a reaction to Ristaben (see section 4)

It is unlikely that this medication will cause low blood sugar because it does not work 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.
