1. What is Mifomet and what is it used for

Mifomet contains two different active substances called sitagliptin and metformin.

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

The combined action of these medicines leads to the normalization of blood sugar levels in adult patients with diabetes known as "type 2 diabetes". This medicine helps to achieve higher insulin levels after meals and reduces the amount of sugar produced by the body. The medicine, used in conjunction with diet and physical exercise, helps to reduce blood sugar levels. This medicine can be used as the only anti-diabetic medicine or in combination with certain other anti-diabetic medicines (insulin, sulfonylurea derivatives, or glitazones). What is type 2 diabetes? Type 2 diabetes is a disease in which the body does not produce enough insulin, and the insulin produced does not work as it should. The body may also produce too much sugar. If this happens, sugar (glucose) accumulates in the blood. This can lead to serious health problems, such as heart disease, kidney disease, vision loss, and limb amputation.

2. Important information before taking Mifomet

When not to take Mifomet:

if the patient has a severe infection or dehydration,

Do not take Mifomet if any of the above contraindications occur. The patient should consult a doctor to determine other methods of controlling diabetes. In case of doubts, before taking Mifomet, the patient should discuss it with their doctor, pharmacist, or nurse.

Warnings and precautions

In patients taking Mifomet, cases of pancreatitis (see section 4) have been reported. If the patient develops blisters on the skin, it may be a sign of a disease called bullous pemphigoid. The doctor may recommend that the patient stop taking Mifomet.

Risk of lactic acidosis

Mifomet may cause a very rare but very serious side effect called lactic acidosis, especially if the patient has kidney problems. The risk of lactic acidosis also increases in cases of uncontrolled diabetes, severe infection, prolonged fasting, or alcohol consumption, dehydration (see more information below), liver dysfunction, and any conditions in which a part of the body is not sufficiently supplied with oxygen (e.g. acute severe heart disease). If any of the above situations apply to the patient, they should consult their doctor for more detailed instructions.

The patient should temporarily stop taking Mifomet if they have a condition that may be associated with dehydration

(significant loss of body water), such as severe vomiting, diarrhea, fever, high temperature, or if the patient drinks less fluid than usual. The patient should consult their doctor for more detailed instructions.

The patient should stop taking Mifomet and immediately contact their doctor or the nearest hospital if they experience any symptoms of lactic acidosis

, as this condition can lead to coma. Symptoms of lactic acidosis include:

• vomiting,
• abdominal pain,
• muscle cramps,
• general feeling of being unwell, accompanied by severe fatigue,
• breathing difficulties,
• decreased body temperature and slowed heart rate.

Lactic acidosis is a life-threatening condition that requires immediate hospital treatment. The patient should contact their doctor immediately if they have a genetically inherited disease affecting the mitochondria (energy-producing structures in cells), such as MELAS syndrome (mitochondrial encephalomyopathy, myopathy, lactic acidosis, and stroke-like episodes) or maternally inherited diabetes and deafness (MIDD), or if they have experienced any of the following symptoms after starting metformin: seizures, impaired cognitive function, difficulty moving, symptoms of nerve damage (e.g. pain or numbness), migraine, or hearing loss.

If the patient is to undergo major surgery, they should not take Mifomet during the surgery and for some time after it. The doctor will decide when the patient should stop and resume treatment with Mifomet. If the patient is unsure whether any of the above statements apply to them, they should discuss it with their doctor or pharmacist before taking Mifomet. During treatment with Mifomet, the doctor will monitor the patient's kidney function at least once a year or more often if the patient is elderly and/or has deteriorating kidney function.

Children and adolescents

This medicine should not be used in children and adolescents under 18 years of age. This medicine is not effective in children and adolescents aged 10 to 17 years. It is not known whether this medicine is safe and effective when used in children under 10 years of age.

Mifomet and other medicines

If the patient is to be injected with a contrast agent containing iodine, for example, during an X-ray examination or computed tomography, they should stop taking Mifomet before or at the latest at the time of the injection. The doctor will decide when the patient should stop and resume treatment with Mifomet. The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. The patient may need more frequent blood glucose and kidney function tests or dose adjustments of Mifomet by the doctor. It is especially important to inform about the following medicines:

• medicines (taken orally, by inhalation, or by injection) used to treat inflammatory diseases, such as asthma or arthritis (corticosteroids),
• medicines that increase urine production (diuretics),
• medicines used to treat pain and inflammation (NSAIDs and COX-2 inhibitors, such as ibuprofen and celecoxib),
• certain medicines used to treat high blood pressure (ACE inhibitors and angiotensin II receptor antagonists),
• specific medicines used to treat asthma (β-sympathomimetics),
• contrast agents containing iodine or medicines containing alcohol,
• some medicines used to treat stomach disorders, such as cimetidine,
• ranolazine, a medicine used to treat angina pectoris,
• dolutegravir, a medicine used to treat HIV infection,
• vandetanib, a medicine used to treat a certain type of thyroid cancer (medullary thyroid cancer),
• digoxin (used to treat heart rhythm disorders and other heart diseases). When taking Mifomet with digoxin, the patient should have their digoxin blood levels monitored.

Mifomet and alcohol

The patient should avoid consuming excessive amounts of alcohol while taking Mifomet, as this may increase the risk of lactic acidosis (see "Warnings and precautions").

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine. This medicine should not be used during pregnancy. This medicine should not be used during breastfeeding. See section 2, When not to take Mifomet.

Driving and using machines

This medicine has no or negligible influence on the ability to drive and use machines. However, when driving and using machines, the patient should take into account that dizziness and drowsiness have been reported in patients taking sitagliptin, which may affect the ability to drive and use machines. Taking this medicine with sulfonylurea derivatives or insulin may lead to hypoglycemia, which may affect the ability to drive and use machines or work without safe foot support.

Mifomet contains sodium

This medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means that the medicine is considered "sodium-free".

3. How to take Mifomet

This medicine should always be taken as directed by the doctor. In case of doubts, the patient should consult their doctor or pharmacist.

• The patient should take one tablet:
• twice a day, orally;
• with meals to reduce the likelihood of stomach upset.
• To control blood sugar levels, the doctor may increase the dose of Mifomet.
• If the patient has kidney problems, the doctor may prescribe a lower dose.

During treatment with this medicine, the patient should continue to follow the diet recommended by their doctor and pay attention to evenly distributed carbohydrate intake throughout the day. It is unlikely that taking this medicine alone will lead to abnormally low blood sugar levels (hypoglycemia). Hypoglycemia may occur when taking this medicine with a sulfonylurea derivative or insulin - in such cases, the doctor may reduce the dose of the sulfonylurea derivative or insulin.

Taking a higher dose of Mifomet than recommended

In case of taking a higher dose of this medicine than recommended, the patient should immediately contact their doctor. The patient should go to the hospital if they experience symptoms of lactic acidosis, such as feeling cold or uncomfortable, severe nausea or vomiting, stomach pain, unexplained weight loss, muscle cramps, or rapid breathing (see "Warnings and precautions").

Missing a dose of Mifomet

In case of missing a dose, the patient should take it as soon as possible. If it is almost time for the next dose, the patient should skip the missed dose and continue taking the medicine as usual. The patient should not take a double dose of this medicine.

Stopping treatment with Mifomet

To maintain control of blood sugar levels, the patient should take this medicine for as long as their doctor recommends. The patient should not stop taking this medicine without consulting their doctor first. Stopping treatment with Mifomet may lead to a recurrence of high blood sugar levels. If the patient has any further doubts about taking this medicine, they should consult their doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. The patient should STOP TAKING MIFOMET AND IMMEDIATELY CONTACT THEIR DOCTORif they experience any of the following serious side effects:

• Severe and persistent abdominal pain (in the stomach area), which may radiate to the back, with or without nausea and vomiting - these may be symptoms of pancreatitis. Mifomet may very rarely cause (may occur in less than 1 in 10,000 patients) a very serious side effect called lactic acidosis (see "Warnings and precautions"). If this occurs, the patient should STOP TAKING MIFOMET AND IMMEDIATELY CONTACT THEIR DOCTOR OR THE NEAREST HOSPITAL, as lactic acidosis can lead to coma.

In case of a severe allergic reaction (frequency not known), including rash, hives, blisters on the skin, or peeling of the skin, and swelling of the face, lips, tongue, and throat, which may cause difficulty breathing or swallowing, the patient should stop taking the medicine and immediately contact their doctor. The doctor may prescribe a medicine to treat the allergic reaction and another medicine (change the medicine) to treat diabetes. In some patients taking metformin, the following side effects have occurred after starting sitagliptin: Common (may occur in less than 1 in 10 patients): low blood sugar, nausea, bloating, vomiting. Uncommon (may occur in less than 1 in 100 patients): stomach pain, diarrhea, constipation, drowsiness. Some patients have experienced diarrhea, nausea, bloating, constipation, stomach pain, or vomiting after starting sitagliptin in combination with metformin (common). In some patients taking this medicine with a sulfonylurea derivative, such as glimepiride, the following side effects have occurred: Very common (may occur in more than 1 in 10 patients): low blood sugar. Common: constipation. In some patients taking this medicine with pioglitazone, the following side effects have occurred: Common: swelling of the hands or feet. In some patients taking this medicine with insulin, the following side effects have occurred: Very common: low blood sugar. Uncommon: dry mouth, headache.

These symptoms may occur after starting metformin and usually disappear. Common: metallic taste, decreased or low vitamin B12 levels in the blood (symptoms may include extreme fatigue, pain, and redness of the tongue, or numbness and tingling). The doctor may order certain tests to find the cause of the symptoms, as some of them may also be caused by diabetes or other unrelated health problems. Very rare: liver inflammation (liver disease), hives, skin redness (rash), or itching.
