Sitagliptin 25 mg Film-Coated Tablets

Sitagliptin Adco contains the active substance sitagliptin which is a member of a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors) that lowers blood sugar levels in adult patients with type 2 diabetes mellitus.

This medicine helps to increase the levels of insulin produced after a meal and decreases the amount of sugar made by the body. Your doctor has prescribed this medicine to help lower your blood sugar, which is too high because of your type 2 diabetes. This medicine can be used alone or in combination with certain other medicines (insulin, metformin, sulphonylureas, or glitazones) that lower blood sugar, which you may already be taking for your diabetes together with a food and exercise plan.

Do not take Sitagliptin Adco:

• if you are hypersensitive (allergic) to sitagliptin or to any of the other ingredients of Sitagliptin Adco (listed in section 6).
• if you have a history of serious hypersensitivity reactions, such as anaphylaxis and angioedema to Sitagliptin Adco or other gliptins (DPP-4).
• if you have severe liver problems.

Warnings and precautions

Take special care with Sitagliptin Adco if you:

• have Type 1 diabetes
• have or have had diabetic ketoacidosis (a complication of diabetes with high blood sugar, rapid weight loss, nausea or vomiting)
• have disease of the pancreas (such as pancreatitis)
• have any past or present kidney problems as your dosage of Sitagliptin Adco may need to be adjusted
• develop a rare skin condition that causes large, fluid-filled blisters (especially on the lower abdomen, upper thighs or armpits). You should stop taking Sitagliptin Adco.

Serious allergic reactions to sitagliptin have been reported (see section 4 below).

Sitagliptin Adco is unlikely to cause low blood sugar because it does not work when your blood sugar is low. However, when this medicine is used in combination with a sulphonylurea medicine or with insulin, low blood sugar (hypoglycaemia) can occur. Your doctor may reduce the dose of your sulphonylurea or insulin medicine.
