What is Jentadueto?

Jentadueto contains a combination of linagliptin and metformin. Linagliptin and metformin are oral diabetes medicines that help control blood sugar levels. Metformin works by decreasing glucose (sugar) production in the liver and decreasing absorption of glucose by the intestines. Linagliptin works by regulating the levels of insulin your body produces after eating.

Jentadueto is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus.

Jentadueto is not for treating type 1 diabetes.

Important Information

You should not use Jentadueto if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment).

There may be an increased risk of developing lactic acidosis, a dangerous build-up of lactic acid in your blood. Call your doctor or get emergency medical help if you have unusual muscle pain, trouble breathing, stomach pain, dizziness, feeling cold, or feeling very weak or tired.

Before you take Jentadueto, tell your doctor if you have liver disease, a serious infection, heart disease, a history of pancreatitis, if you have recently had a heart attack, or if you are over 65 years old and have not recently had your kidney function checked.

If you need to have surgery or any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking Jentadueto.

Before taking this medicine

You should not use Jentadueto if you are allergic to linagliptin (Tradjenta) or metformin, or if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment with insulin).

Tell your doctor if you have ever had:

You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, a severe infection, chronic alcoholism, or if you are 65 or older. Ask your doctor about your risk.

If you need to have surgery or any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking Jentadueto. Be sure your caregivers know ahead of time that you are using this medication.

Follow your doctor's instructions about using this medicine if you are pregnant or breast-feeding a baby. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester of pregnancy. Your dose needs may also be different while you are breast-feeding.

This medicine may stimulate ovulation in a premenopausal woman and may increase the risk of unintended pregnancy. Talk to your doctor about your risk.

This medicine is not approved for use by anyone younger than 18 years old.

How should I take Jentadueto?

Take Jentadueto exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Take Jentadueto twice daily with meals, unless your doctor tells you otherwise.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.

Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.

Jentadueto is only part of a complete treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.

Store at room temperature away from moisture and heat.
