Brand Names: Jentadueto

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 to treat type 2 diabetes.

Jentadueto is not for treating type 1 diabetes.

Important information

You should not use Jentadueto if you have ever had a severe allergic reaction to linagliptin. Do not use this medicine if you have kidney disease, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).

Jentadueto may cause a serious condition called lactic acidosis. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, fast or uneven heart rate, dizziness, 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 80 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 metformin (Actoplus Met, Avandamet, Fortamet, Glucophage, Riomet); or

  • if you have ever had a severe allergic reaction (breathing problems, swelling, severe skin rash) to linagliptin (Onglyza);

  • if you have kidney disease; or

  • if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).

Some people taking metformin develop a serious condition called lactic acidosis. This may be more likely if you have liver or kidney disease, congestive heart failure, a severe infection, if you are dehydrated, or if you drink large amounts of alcohol. Talk with your doctor about your risk.

To make sure Jentadueto is safe for you, tell your doctor if you have:

  • liver disease;

  • heart disease;

  • a serious infection called sepsis;

  • a history of pancreatitis;

  • gallstones;

  • a history of alcoholism;

  • high triglycerides (a type of fat in the blood);

  • if you have recently had a heart attack; or

  • if you are over 80 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. Be sure your caregivers know ahead of time that you are using this medication.

Jentadueto is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether linagliptin and metformin passes into breast milk or if it could harm a nursing baby. You should not breast-feed while you are using this medicine.

Jentadueto 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. Do not take this medicine in larger or smaller amounts or for longer than recommended. Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.

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, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.

If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.

Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor's advice.

Your doctor may have you take extra vitamin B12 while you are taking metformin. Take only the amount of vitamin B12 that your doctor has prescribed.

Jentadueto is only part of a 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 Jentadueto at room temperature away from moisture and heat.
