Sitagliptin/Metformin hydrochloride tablet 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 medicine helps to increase the levels of insulin produced after a meal and lowers the amount of sugar made by your body.
Along with diet and exercise, this medicine helps lower your blood sugar. This medicine can be used alone or with certain other medicines for diabetes (insulin, sulphonylureas, or glitazones).
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.
Do not take Sitagliptin/Metformin hydrochloride if any of the above apply to you and talk with your doctor about other ways of managing your diabetes. If you are not sure, talk to your doctor, pharmacist or nurse before taking Sitagliptin/Metformin hydrochloride.
Cases of inflammation of the pancreas (pancreatitis) have been reported in patients receiving Sitagliptin/Metformin hydrochloride (see section 4).
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 Sitagliptin/Metformin hydrochloride.
Sitagliptin/Metformin hydrochloride may cause a very rare, but very serious side effect 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 Sitagliptin/Metformin hydrochloride 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 instructions.
Stop taking Sitagliptin/Metformin hydrochloride 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:
Lactic acidosis is a medical emergency and must be treated in a hospital.
Talk to your doctor or pharmacist before taking Sitagliptin/Metformin hydrochloride:
If you need to have major surgery you must stop taking Sitagliptin/Metformin hydrochloride during and for some time after the procedure. Your doctor will decide when you must stop and when to restart your treatment with Sitagliptin/Metformin hydrochloride.
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Sitagliptin/Metformin hydrochloride.
During treatment with Sitagliptin/Metformin hydrochloride, 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 below 18 years should not use this medicine. 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.
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 Sitagliptin/Metformin hydrochloride before or at the time of the injection. Your doctor will decide when you must stop and when to restart your treatment with Sitagliptin/Metformin hydrochloride.
Tell your doctor or pharmacist 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 Sitagliptin/Metformin hydrochloride. It is especially important to mention the following:
Avoid excessive alcohol intake while taking Sitagliptin/Metformin hydrochloride since this may increase the risk of lactic acidosis (see section “Warnings and precautions”).
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, speak to your doctor in case any changes will be needed to your treatment or monitoring of your blood glucose levels. This medicine is not recommended if you are breast-feeding or if you are planning to breast-feed your baby. See section 2, Do not take Sitagliptin/Metformin hydrochloride.
This medicine has no or negligible influence on the ability to drive and use machines. However, dizziness and drowsiness have been reported with sitagliptin, which may affect your ability to drive or use machines.
Taking this medicine in combination with medicines called sulphonylureas or with insulin can cause hypoglycaemia, which may affect your ability to drive and use machines or work without safe foothold.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
The usual recommended dose is:
You should continue the diet recommended by your doctor during treatment with this medicine and take care that your carbohydrate intake is equally distributed over the day.
This medicine alone is unlikely to cause abnormally low blood sugar (hypoglycaemia). When this medicine 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 than the prescribed dosage of this medicine, contact your doctor immediately.
Go to the hospital if you have symptoms of lactic acidosis such as feeling cold or uncomfortable, severe nausea or vomiting, stomach ache, unexplained weight loss, muscular cramps, or rapid breathing (see section “Warnings and precautions”).
If you miss a dose, take it as soon as you remember. If you do not remember until it is time for your next dose, skip the missed dose and go back to your regular schedule. Do not take a double dose of this medicine.
Continue to take this medicine as long as your doctor prescribes it so you can continue to help control your blood sugar. You should not stop taking this medicine without talking to your doctor first. If you stop taking Sitagliptin/Metformin hydrochloride, your blood sugar may rise again.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
STOP taking Sitagliptin/Metformin hydrochloride and contact a doctor immediately if you notice any of the following serious side effects:
Sitagliptin/Metformin hydrochloride may cause a very rare (may affect up to 1 in 10,000 people), but very serious side effect called lactic acidosis (see section “Warnings and precautions”). If this happens, you must stop taking Sitagliptin/Metformin hydrochloride and contact a doctor or the nearest hospital immediately, as lactic acidosis may lead to coma.
If you have a serious allergic reaction (frequency not known), including rash, hives, blisters on the skin/peeling skin and swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing, stop taking this medicine and call your doctor right away. Your doctor may prescribe a medicine to treat your allergic reaction and a different medicine for your diabetes.
