Patient leaflet - Jentadueto 2.5 mg / 1000 mg film-coated tablets
1. What Jentadueto is and what it is used for
The name of your tablet is Jentadueto. It contains two different active substances linagliptin and metformin.
Linagliptin belongs to a class of medicines
called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors).
Metformin belongs to a class of medicines
called biguanides.
How Jentadueto works
The two active substances work together to control blood sugar levels in adult patients with a form of diabetes called ‘type 2 diabetes mellitus’. Along with diet and exercise, this medicine helps to improve the levels and effects of insulin after a meal and lowers the amount of sugar made by your body.
This medicine can be used alone or with certain other medicines for diabetes like sulphonylureas, empagliflozin, or insulin.
What is type 2 diabetes?
Type 2 diabetes is a condition in which your body does not make enough insulin, and the insulin that your body produces does not work as well as it should. Your body can also make too much sugar. When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems like heart disease, kidney disease, blindness, and amputation.
2. What you need to know before you take Jentadueto
Do not take Jentadueto
if you are allergic to linagliptin or metformin or
any of the other ingredients of this medicine (listed in section 6).
- if you have severely reduced kidney function.
if you have uncontrolled diabetes, with, for
example, severe hyperglycaemia (high blood glucose), nausea, vomiting, diarrhoea, rapid weight loss, lactic acidosis (see “Risk of lactic acidosis” below) or ketoacidosis. Ketoacidosis is a condition in which substances called ‘ketone bodies’ accumulate in the blood and which can lead to diabetic pre-coma. Symptoms include stomach pain, fast and deep breathing, sleepiness or your breath developing an unusual fruity smell.
- if you ever had a diabetic pre-coma.
if you have a severe infection such as an
infection affecting your lung or bronchial system or your kidney. Severe infections may lead to kidney problems, which can put you at risk for lactic acidosis (see ‘Warnings and precautions’).
if you have lost a lot of water from your body
(dehydration), e.g. due to long-lasting or severe diarrhoea, or if you have vomited several times in a row. Dehydration may lead to kidney problems, which can put you at risk for lactic acidosis (see ‘Warnings and precautions’).
if you are treated for acute heart failure or
have recently had a heart attack, have severe problems with your circulation (such as shock) or have breathing difficulties. This may lead to a lack in oxygen supply to tissue which can put you at risk for lactic acidosis (see ‘Warnings and precautions’).
- if you have liver problems.
if you drink alcohol to excess, either every
day or only from time to time (see section ‘Jentadueto with alcohol’).
Do not take Jentadueto if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before taking Jentadueto
if you have type 1 diabetes (your body does not
produce any insulin). Jentadueto should not be used to treat this condition.
if you are taking insulin or an anti-diabetic
medicine known as ‘sulphonylurea’, your doctor may want to reduce your dose of insulin or sulphonylurea when you take either of them together with Jentadueto in order to avoid low blood sugar (hypoglycaemia).
if you have or have had a disease of
the pancreas.
If you have symptoms of acute pancreatitis, like persistent, severe abdominal pain, you should consult your doctor.
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 Jentadueto.
If you are not sure if any of the above applies to you, talk to your doctor, pharmacist or nurse before taking Jentadueto.
Diabetic skin problems are a common complication of diabetes. You are advised to follow the recommendations for skin and foot care that you are given by your doctor or nurse.
Risk of lactic acidosis.
Due to the metformin component, Jentadueto may cause a very rare, but very serious complication called lactic acidosis, particularly if your kidneys are not working properly. The risk of developing lactic acidosis is also increased with uncontrolled diabetes, serious infections, prolonged fasting or alcohol intake, dehydration (see further information below), liver problems and any medical conditions in which a part of the body has a reduced supply of oxygen (such as acute severe heart disease). If any of the above apply to you, talk to your doctor for further instructions.
Stop taking Jentadueto for a short time if you have a condition that may be associated with dehydration (significant loss of body fluids) such as severe vomiting, diarrhoea, fever, exposure to heat or if you drink less fluid than normal. Talk to your doctor for further instruction.
Stop taking Jentadueto and contact a doctor or the nearest hospital immediately if you experience some of the symptoms of lactic acidosis, as this condition may lead to coma. Symptoms of lactic acidosis include:
- vomiting
- stomach ache (abdominal pain)
- muscle cramps
a general feeling of not being well with severe
tiredness
- difficulty in breathing
reduced body temperature and heartbeat
Talk to your doctor promptly for further instructions
if you are known to suffer from a genetically
inherited disease affecting mitochondria (the energy-producing components within cells) such as MELAS syndrome (Mitochondrial Encephalopathy, myopathy, Lactic acidosis and Stroke-like episodes) or Maternal inherited diabetes and deafness (MIDD).
if you have any of these symptoms after
starting metformin: seizure, declined cognitive abilities, difficulty with body movements, symptoms indicating nerve damage (e.g. pain or numbness), migraine and deafness.
Lactic acidosis is a medical emergency and must be treated in a hospital.
If you need to have major surgery you must stop taking Jentadueto during and for some time after the procedure. Your doctor will decide when you must stop and when to restart your treatment with Jentadueto.
During treatment with Jentadueto, 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.
Children and adolescents
This medicine is not recommended for use in children and adolescents under 18 years. It is not effective in children and adolescents between the ages of 10 and 17 years. It is not known if this medicine is safe and effective when used in children younger than 10 years.
Other medicines and Jentadueto
If you need to have an injection of a contrast medium that contains iodine into your bloodstream, for example in the context of an X-ray or scan, you must stop taking Jentadueto before or at the time of the injection. Your doctor will decide when you must stop and when to restart your treatment with Jentadueto.
Tell your doctor if you are taking, have recently taken or might take any other medicines. You may need more frequent blood glucose and kidney function tests, or your doctor may need to adjust the dosage of Jentadueto. It is especially important to mention the following:
medicines which increase urine
production (diuretics)
medicines used to treat pain and inflammation
(NSAID and COX-2-inhibitors, such as ibuprofen and celecoxib)
certain medicines for the treatment of high
blood pressure (ACE inhibitors and angiotensin II receptor antagonists)
medicines that may change the amount of
metformin in your blood, especially if you have reduced kidney function (such as verapamil, rifampicin, cimetidine, dolutegravir, ranolazine, trimethoprim, vandetanib, isavuconazole, crizotinib, olaparib).
carbamazepine, phenobarbital or phenytoin.
These may be used to control fits (seizures) or chronic pain.
rifampicin. This is an antibiotic used to treat
infections such as tuberculosis.
medicines used to treat diseases that
involve inflammation, like asthma and arthritis (corticosteroids).
bronchodilators (β-sympathomimetics) for the
treatment of bronchial asthma.
- alcohol-containing medicines.
Jentadueto with alcohol
Avoid excessive alcohol intake while taking Jentadueto since this may increase the risk of lactic acidosis (see section ‘Warnings and precautions’).
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
You should not use Jentadueto if you are pregnant. It is unknown if this medicine is harmful to the unborn child.
Metformin passes into human milk in small amounts. It is not known whether linagliptin passes into human milk. Talk to your doctor if you want to breast-feed while taking this medicine.
Driving and using machines
Jentadueto has no or negligible influence on the ability to drive and use machines.
However, taking Jentadueto in combination with medicines called sulphonylureas or with insulin can cause too low blood sugar level (hypoglycaemia), which may affect your ability to drive and use machines or work without safe foothold.
3. How to take Jentadueto
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
How much to take
The amount of Jentadueto that you will take varies depending on your condition and the doses you currently take of metformin and/or individual tablets of linagliptin and metformin. Your doctor will tell you exactly the dose of this medicine to take.
How to take this medicine
one tablet twice daily by mouth in the dose
prescribed by your doctor.
with meals to lower your chance of an
upset stomach.
You should not exceed the maximum recommended daily dose of 5 mg linagliptin and 2 000 mg metformin hydrochloride.
Continue to take Jentadueto as long as your doctor prescribes it so you can continue to help control your blood sugar. Your doctor may prescribe this medicine together with another oral anti-diabetic medicine or insulin. Remember to take all medicines as directed by your doctor to achieve the best results for your health.
You should continue your diet during treatment with Jentadueto and take care that your carbohydrate intake is equally distributed over the day. If you are overweight, continue your energy-restricted diet as instructed. This medicine alone is unlikely to cause abnormally low blood sugar (hypoglycaemia). When Jentadueto is used with a sulphonylurea medicine or with insulin, low blood sugar can occur and your doctor may reduce the dose of your sulphonylurea or insulin.
If you take more Jentadueto than you should
If you take more Jentadueto tablets than you should have, you may experience lactic acidosis. Symptoms of lactic acidosis are non-specific such as feeling or being very sick, vomiting, stomach ache with muscle cramps, a general feeling of not being well with severe tiredness, and difficulty in breathing. Further symptoms are reduced body temperature and heartbeat. If this happens to you, you may need immediate hospital treatment, as lactic acidosis can lead to coma. Stop taking this medicine immediately and contact a doctor or the nearest hospital straight away (see section 2). Take the medicine pack with you.
If you forget to take Jentadueto
If you forget to take a dose, take it as soon as you remember it. However, if it is nearly time for the next dose, skip the missed dose. Do not take a double dose to make up for a forgotten dose. Never take two doses at the same time (morning or evening).
If you stop taking Jentadueto
Keep taking Jentadueto until your doctor tells you to stop. This is to help keep your blood sugar under control.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Some symptoms need immediate medical attention
You should stop taking Jentadueto and see your doctor straight away if you experience the following symptoms of low blood sugar (hypoglycaemia): trembling, sweating, anxiety, blurred vision, tingling lips, paleness, mood change, or confusion. Hypoglycaemia (frequency very common (may affect more than 1 in 10 people)) is an identified side effect for the combination of Jentadueto plus sulphonylurea and for the combination Jentadueto plus insulin.
