GLUSITA 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. Along with diet and exercise, this medicine helps 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.
1. What GLUSITA is and what it is used for.
2. What you need to know before you take GLUSITA.
Do not take GLUSITA if:
- You are hypersensitive (allergic) to sitagliptin or other gliptins (DPP - 4), or any of the other ingredients of GLUSITA (listed in section 6).
Warnings and precautions
Tell your doctor or health care provider before taking GLUSITA:
- If you have type 1 diabetes. GLUSITA should not be used in patients with type 1 diabetes and must not be used for the treatment of diabetic ketoacidosis (a complication of diabetes with high blood sugar, rapid weight loss, nausea or vomiting).
- If you have or have had a disease of the pancreas (such as pancreatitis). Cases of inflammation of the pancreas (pancreatitis) have been reported in patients receiving GLUSITA. If you have or have had gallstones, alcohol dependence or very high levels of triglycerides (a form of fat) in your blood you may have an increased chance of getting pancreatitis (see section 4).
- This medicine 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.
- If you encounter blistering of the skin it may be a sign for a condition called bullous pemphigoid. Your doctor may ask you to stop GLUSITA.
- If you have kidney problems or reduced kidney function. During treatment with GLUSITA, your doctor will check your kidney function at least once a year or more frequently if you are elderly and/or if you have worsening kidney function.
- If you have or have had an allergic reaction to sitagliptin or GLUSITA (see section 4).
