Contents of the pack
Sitagliptin/Metformin Normon 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 amount of insulin produced after a meal and reduces the amount of sugar produced by your body.
Together with diet and exercise, this medicine helps to lower your blood sugar levels. This medicine can be used alone or with certain other medicines for diabetes (insulin, sulfonylureas, or glitazones).
What is type 2 diabetes?
Type 2 diabetes is a condition where your body does not produce enough insulin and the insulin that 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 diseases (cardiac), kidney diseases (renal), blindness, and amputations.
Do not take Sitagliptin/Metformin Normon
Do not take this medicine if any of the above applies to you and consult your doctor about other ways to control your diabetes. If you are not sure, consult your doctor, pharmacist, or nurse before taking this medicine.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before taking this medicine.
There have been reports of pancreatitis (inflammation of the pancreas) in patients treated with this medicine (see section 4).
If you notice blisters on your skin, it may be a sign of a disease called bullous pemphigoid. Your doctor may ask you to stop taking this medicine.
Risk of lactic acidosis
This medicine may cause a very rare but very serious side effect called lactic acidosis, especially 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 more information below), liver problems, and any medical condition in which a part of your body has a reduced supply of oxygen (such as acute and severe heart diseases).
If any of the above applies to you, consult your doctor for further instructions.

Stop taking this medicine and contact a doctor or the nearest hospital immediately if you experience any of the symptoms of lactic acidosis, as this condition can lead to coma.
The symptoms of lactic acidosis include:
Lactic acidosis is a medical emergency and must be treated in a hospital.

Other medicines and Sitagliptin/Metformin Normon
If you need to be given an injection of a contrast agent containing iodine into your bloodstream, for example, in the context of an X-ray or scan, you should stop taking this medicine before the injection or at the time of the injection. Your doctor will decide when you should stop taking this medicine and when you can restart it.
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 dose of this medicine. It is especially important to mention the following:
Taking Sitagliptin/Metformin Normon with alcohol
Avoid excessive alcohol intake while taking this medicine, as 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 take this medicine during pregnancy or while breast-feeding. See section 2, Do not take Sitagliptin/Metformin Normon.
Driving and using machines
The effect of this medicine on your ability to drive or 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 or use machines.
Taking this medicine with sulfonylureas or insulin may cause hypoglycemia, which may affect your ability to drive or use machines or work without a safe support.
Sitagliptin/Metformin Normon contains sodium
This medicine contains less than 23 mg of sodium (1 mmol) per tablet; this is essentially “sodium-free”.

You should continue with the diet recommended by your doctor during treatment with this medicine and be careful to distribute your carbohydrate intake evenly throughout the day.
It is unlikely that treatment with this medicine alone will cause abnormally low blood sugar levels (hypoglycemia). Low blood sugar may occur when this medicine is taken with a sulfonylurea or insulin, so your doctor may consider it necessary to reduce the dose of your sulfonylurea or insulin.
