Sitagliptin/Metformin hydrochloride

Read this package insert carefully before starting to take this medicine, as it contains important information for you.

• Keep this package insert, as you may need to read it again.
• If you have any questions, consult your doctor, pharmacist, or nurse.
• This medicine has been prescribed only for you, and you should not give it to others even if they have the same symptoms as you, as it may harm them.
• If you experience any adverse effects, consult your doctor, pharmacist, or nurse, even if they are not listed in this package insert. See section 4.

Sitagliptina/Metformina Normon contains two different medicines, called sitagliptin and metformin.

• Sitagliptin belongs to a class of medicines called DPP-4 inhibitors (dipeptidyl peptidase-4 inhibitors).
• Metformin belongs to a class of medicines called biguanides.

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 reduces the amount of sugar produced by the body.

Along with a diet and exercise, this medicine helps to lower your blood sugar level. This medicine can be used alone or with certain diabetes medicines (insulin, sulfonylureas or thiazolidinediones).

What is type 2 diabetes?

Type 2 diabetes is a disease in which 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 occurs, sugar (glucose) accumulates in the blood. This can lead to serious medical problems, such as heart diseases (cardiovascular), kidney diseases (renal), blindness, and amputations.

Do not take Sitagliptina/Metformina Normon

• If you are allergic to sitagliptin, metformin, or any of the other components of this medication (listed in section 6).
• If you have severe kidney function reduction.
• If you have uncontrolled diabetes, for example, severe hyperglycemia (high blood glucose), nausea, vomiting, diarrhea, rapid weight loss, lactic acidosis (see "Risk of lactic acidosis" below), or ketoacidosis. Ketoacidosis is a disorder in which substances called "ketone bodies" accumulate in the blood, which can lead to diabetic precoma. Symptoms include stomach pain, rapid and deep breathing, drowsiness, or if your breath develops an unusual fruity odor.
• If you have a severe infection or are dehydrated.
• If you are to undergo a radiography that requires the injection of a contrast agent. You will need to stop taking this medication at the time of the radiography and for 2 or more days after, as instructed by your doctor, depending on the functioning of your kidneys.
• If you have recently had a heart attack or have severe circulatory problems, such as "shock" or difficulty breathing.
• If you have liver problems (hepatic).
• If you drink excessive alcohol (whether daily or occasionally).
• If you are breastfeeding.

Do not take this medication 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 starting to take this medication.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take this medication.

Cases of pancreatitis have been reported in patients treated with this medication (see section 4).

If you observe blisters on your skin, it may be a sign of a disease called bullous pemphigoid. Your doctor may ask you to stop taking this medication.

Risk of lactic acidosis

This medication may cause a 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 acute and severe heart diseases).

If any of the above applies to you, consult your doctor for further instructions.

Consult your doctor immediately if:

• You have a genetic disorder that affects the mitochondria (the components that produce energy inside cells), such as MELAS syndrome (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes) or maternal diabetes and deafness (MIDD).

• You experience any of the following symptoms after starting treatment with metformin: convulsions, cognitive decline, difficulty with motor movements, symptoms indicative of nerve damage (e.g., pain or numbness), migraine, and hearing loss.

Stop taking this medication for a short period if you have a condition that may be associated with dehydration(significant loss of body fluids), such as intense vomiting, diarrhea, fever, exposure to heat, or if you drink less fluid than normal. Consult your doctor for further instructions.

Stop taking this medication 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:

• Vomiting.
• Abdominal pain (stomach pain).
• Muscle cramps.
• General feeling of discomfort, with intense fatigue.
• Difficulty breathing.
• Reduced body temperature and heart rate.

Lactic acidosis is a medical emergency and should be treated in a hospital.

Consult your doctor or pharmacist before starting to take this medication:

• If you have or have had pancreatitis.
• If you have or have had gallstones, alcohol addiction, or have very high levels of triglycerides (a type of fat) in your blood. These medical conditions may increase your risk of developing pancreatitis (see section 4).
• If you have type 1 diabetes. This disease is also known as insulin-dependent diabetes.
• If you have or have had an allergic reaction to sitagliptin, metformin, or the combination of sitagliptin/metformin (see section 4).
• If you are taking a sulfonilurea or insulin, other diabetes medications, as you may experience low blood sugar (hypoglycemia). Your doctor may consider reducing the dose of the sulfonilurea or insulin you are taking.

If you need to undergo major surgery, stop taking this medication while the procedure is being performed and for a period after. Your doctor will decide when to interrupt treatment with this medication and when to restart it.

If you are unsure whether you are affected by any of the above circumstances, consult your doctor or pharmacist before starting to take this medication.

Driving and operating machinery

The influence of this medication on your ability to drive and operate machinery is negligible or insignificant. However, cases of dizziness and somnolence have been reported during treatment with sitagliptin, which may affect your ability to drive and operate machinery.

Taking this medication with medications called sulfonilureas or insulin may cause hypoglycemia, which may affect your ability to drive and operate machinery or work without a secure support.

Sitagliptina/Metformina Normon contains sodium

This medication contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially "sodium-free".

Follow exactly the administration instructions for this medication as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

• Take one tablet:
• • Twice a day by mouth.
  • With food to reduce the likelihood of stomach discomfort.
• Your doctor may need to increase the dose to control blood sugar levels.
• If you have reduced renal function, your doctor may prescribe a lower dose.

You must continue with the diet recommended by your doctor during treatment with this medication and be careful to distribute carbohydrate intake evenly throughout the day.

It is unlikely that treatment with this medication alone will cause abnormally low blood sugar (hypoglycemia). Hypoglycemia may occur when this medication is taken with a medication containing sulfonylurea or with insulin, so your doctor may need to reduce the dose of your sulfonylurea or insulin.
