sitagliptin/metformin hydrochloride.
Sitagliptin/Metformin GLN contains two different medicines, called sitagliptin and metformin.
They work together to control blood sugar levels in adult patients with a form of diabetes called "type 2 diabetes mellitus". This medication helps increase insulin production after a meal and reduces the amount of sugar produced by your body.
Along with diet and exercise, this medication helps lower your blood sugar level. This medication can be used alone or with certain diabetes medications (insulin, sulfonylureas, or glitazones).
What is type 2 diabetes?
Type 2 diabetes is a disease in which your body does not produce enough insulin and the insulin your body produces does not work as well as it should. Your body may also produce too much sugar. When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems, such as heart disease, kidney disease, blindness, and amputations.
Do not take Sitagliptin/Metformin GLN if any of the above circumstances apply to you, and consult your doctor about other ways to control your diabetes. If you are unsure, consult your doctor, pharmacist, or nurse before taking Sitagliptin/Metformin GLN.
Cases of pancreatitis have been reported in patients treated with Sitagliptin/Metformin GLN (see section 4).
If you notice blisters on the skin, it may be a sign of a disease called bullous pemphigoid. Your doctor may ask you to stop taking Sitagliptin/Metformin GLN.
Sitagliptin/Metformin GLN may cause a very rare but serious side effect called lactic acidosis, especially if your kidneys do not function properly. The risk of developing lactic acidosis is also increased with uncontrolled diabetes, severe infections, prolonged fasting, or alcohol consumption, dehydration (see more information below), liver problems, and any medical condition in which a part of the body has a reduced oxygen supply (such as severe and acute heart disease).
If any of the above applies to you, consult your doctor for further instructions.
Consult your doctor immediately to determine how to proceed if:
Stop taking Sitagliptin/Metformin GLN for a short period if you have a condition that may be associated with dehydration(significant loss of body fluids), such as severe vomiting, diarrhea, fever, heat exposure, or if you drink less fluid than usual. Consult your doctor for further instructions.
Stop taking Sitagliptin/Metformin GLN and contact a doctor or the nearest hospital immediately if you experience any symptoms of lactic acidosis, as this condition can lead to coma.
The symptoms of lactic acidosis include:
Consult your doctor or pharmacist before starting to take Sitagliptin/Metformin GLN:
If you need to undergo major surgery, you should stop taking Sitagliptin/Metformin GLN during the procedure and for a period after. Your doctor will decide when you should stop taking Sitagliptin/Metformin GLN and when to restart it.
If you are unsure whether any of the above circumstances apply to you, consult your doctor or pharmacist before taking Sitagliptin/Metformin GLN.
During treatment with Sitagliptin/Metformin GLN, your doctor will check your kidney function at least once a year or more frequently if you are an elderly person and/or if your kidney function is worsening.
Children and adolescents under 18 years of age should not use this medication. It is not known if this medication is safe and effective when used in children and adolescents under 18 years of age.
If you need to be administered an injection of a contrast agent containing iodine into your bloodstream, for example, in the context of an X-ray examination or scan, you should stop taking Sitagliptin/Metformin GLN before the injection or at the time of the injection. Your doctor will decide when you should stop taking Sitagliptin/Metformin GLN and when to restart it.
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medication. You may need more frequent blood glucose and kidney function tests, or your doctor may need to adjust the dose of Sitagliptin/Metformin GLN. It is especially important to mention the following:
Avoid excessive alcohol consumption while taking Sitagliptin/Metformin GLN, as this may increase the risk of lactic acidosis (see section "Warnings and precautions").
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication. You should not take this medication during pregnancy or while breastfeeding. See section 2, Do not take Sitagliptin/Metformin GLN.
The influence of this medication on the ability to drive and use machines is negligible or non-existent. However, cases of dizziness and drowsiness have been reported during treatment with sitagliptin, which may affect your ability to drive and use machines.
Taking this medication with sulfonylureas or insulin may cause hypoglycemia, which may affect your ability to drive and use machines or work without a secure support.
Sitagliptin/Metformin GLN contains sodium
This medication contains less than 1 mmol (23 mg) of sodium per tablet, so it is considered essentially "sodium-free".
Follow the instructions for taking this medication exactly as indicated by your doctor. If you are unsure, consult your doctor or pharmacist again.
You should continue with the diet recommended by your doctor during treatment with this medication and ensure that your carbohydrate intake is evenly distributed throughout the day.
It is unlikely that treatment with this medication alone will cause abnormally low blood sugar levels (hypoglycemia). Hypoglycemia may occur when this medication is taken with a medication that contains a sulfonylurea or with insulin, so your doctor may consider it necessary to reduce the dose of your sulfonylurea or insulin.
The score line is not intended to be used to break the tablet.
If you take more than the prescribed dose of this medication, contact your doctor immediately. Go to the hospital if you have symptoms of lactic acidosis, such as a feeling of coldness or discomfort, nausea or severe vomiting, stomach pain, unexplained weight loss, muscle cramps, or rapid breathing (see section "Warnings and precautions").
In case of overdose or accidental ingestion, consult the Toxicology Information Service. Telephone 91 562 04 20.
If you forget to take a dose, take it as soon as you remember. If you do not remember until the time of your next dose, skip the missed dose and continue with your regular treatment. Do not take a double dose of this medication.
Continue taking Sitagliptin/Metformin GLN for as long as your doctor tells you to, to help control your blood sugar levels. You should not stop taking this medication without consulting your doctor first. If you stop taking Sitagliptin/Metformin GLN, your blood sugar levels may increase again.
If you have any further questions about the use of this medication, ask your doctor or pharmacist.
