1. What is Formetic and what is it used for

Formetic belongs to a group of medicines used to treat type 2 diabetes mellitus in adults and children over 10 years old.
Formetic is a medicine that lowers blood sugar levels in patients with diabetes (type 2 diabetes),
especially in patients who are overweight and cannot achieve proper blood sugar levels through diet and physical activity.

• 2); especially in patients who are overweight and cannot achieve proper blood sugar levels through diet and physical activity.

Adults

In adults, the doctor may prescribe Formetic as the only anti-diabetic medicine (monotherapy) or in combination with other oral anti-diabetic medicines or insulin.

Children and adolescents

In children over 10 years old and adolescents, the doctor may prescribe Formetic as the only anti-diabetic medicine (monotherapy) or in combination with insulin.
It has been shown that metformin reduces the risk of complications in patients with type 2 diabetes and overweight, treated with metformin as the first-line treatment, in whom diet therapy did not produce the expected results.
Formetic can be used in a condition called pre-diabetes, when proper blood sugar control cannot be achieved through diet and physical activity.
Formetic can also be used in polycystic ovary syndrome (hormonal disorders in women, with symptoms such as irregular menstrual cycle, acne, weight gain and difficulty losing weight, excessive hair growth on the face and body, and difficulty getting pregnant).

2. Important information before taking Formetic

When not to take Formetic

• dehydration caused by prolonged vomiting or severe diarrhea
• severe infection
• shock
• heart or respiratory failure
• recent myocardial infarction
• shock

Warnings and precautions

Before starting treatment with Formetic, discuss it with your doctor or pharmacist.

Risk of lactic acidosis

Formetic 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 increases in case of uncontrolled diabetes, severe infection, prolonged fasting or alcohol consumption, dehydration (see more information below), liver problems, and any conditions in which a part of the body is not sufficiently supplied with oxygen (e.g., severe heart disease).
If any of the above circumstances apply to the patient, they should consult their doctor for more detailed instructions.

Temporarily stop taking Formetic if the patient has a condition

that may be associated with dehydration(significant water loss), such as severe vomiting, diarrhea, fever, exposure to high temperatures, or if the patient drinks less fluid than usual. The patient should consult their doctor for more detailed instructions.

Stop taking Formetic and immediately contact your doctor or the nearest hospital if the patient experiences

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 with severe fatigue,
• breathing difficulties,
• decreased body temperature and slowed heart rate.

Lactic acidosis is a life-threatening condition that requires immediate hospital treatment.

Immediately consult your doctor if:

• the patient has a genetically inherited disease affecting the mitochondria (energy-producing structures in cells), such as MELAS syndrome (mitochondrial encephalopathy, myopathy, lactic acidosis, and stroke-like episodes) or maternally inherited diabetes and deafness.
• the patient experiences 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 Formetic during or for some time after the surgery. The doctor will decide when the patient should stop and resume treatment with Formetic.
During treatment with Formetic, 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 impaired kidney function.
Special caution should be exercised when using the medicine in situations where kidney function may be impaired (e.g., when starting treatment with a blood pressure-lowering medicine or a non-steroidal anti-inflammatory medicine).
The patient should inform their doctor about any bacterial or viral infection (e.g., flu, respiratory or urinary tract infection).
The patient should continue their diet while taking Formetic, with regular carbohydrate intake during the day (starchy foods like rice, pasta, potatoes, fruits). Overweight patients should also follow a low-calorie diet under medical supervision.
Children and adolescents:
Before taking Formetic, the diagnosis of type 2 diabetes should be confirmed by the doctor.
No effect of metformin on growth and sexual maturation has been observed during one-year clinical trials, but long-term data in children and adolescents are not available.
Due to the fact that only a few children aged 10-12 participated in clinical trials, children of this age should be treated with metformin with special caution.
Elderly patients
Since kidney function in elderly patients is often impaired, the doctor should adjust the dose of Formetic according to kidney function. Therefore, regular assessment of kidney function by the doctor is necessary in these patients.

Formetic and other medicines

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.
If the patient is to receive an iodine-containing contrast agent intravenously, for example, for an X-ray examination or computed tomography, they should stop taking Formetic before or at the latest at the time of administration. The doctor will decide when the patient should stop and resume treatment with Formetic.
During treatment with Formetic, starting or stopping other medicines may have an adverse effect on blood glucose control.
The patient should tell their doctor 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 monitoring and kidney function tests or dose adjustment of Formetic by the doctor. It is especially important to inform about the following medicines:

• corticosteroids (e.g., prednisolone),
• 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),
• medicines used to treat asthma (beta-sympathomimetics, e.g., salbutamol).

Taking Formetic with alcohol

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

Pregnancy, breastfeeding, and fertility

Women with diabetes who are pregnant or plan to become pregnant should not take Formetic. To maintain blood glucose levels as close to normal as possible, insulin should be used. The patient should inform their doctor about pregnancy or planned pregnancy, as the doctor should use insulin in such cases.
Formetic should not be taken during breastfeeding.
In pregnancy, breastfeeding, or if pregnancy is suspected, or if the patient plans to become pregnant, they should consult their doctor or pharmacist before taking this medicine.

Driving and using machines

Taking metformin as the only medicine (monotherapy) does not cause significant hypoglycemia, so Formetic does not affect the ability to drive or use machines.
However, when metformin is used in combination with sulfonylurea derivatives, insulin, or other anti-diabetic medicines, the patient's ability to drive or use machines or perform work that requires concentration may be impaired due to hypoglycemia (with symptoms such as sweating, fainting, dizziness, or weakness).

3. How to take Formetic

This medicine should always be taken exactly as prescribed by the doctor. If in doubt, consult the doctor or pharmacist.
Treatment of type 2 diabetes
The dose of Formetic should be determined by the doctor based on blood glucose levels.
To adjust the dose individually, the 1000 mg coated tablet can be divided into two equal parts containing 500 mg of metformin hydrochloride each. Coated tablets are also available in doses of 500 mg and 850 mg of metformin hydrochloride.
How to break the tablet:
If necessary, the coated tablet can be divided into two equal parts.
Place the tablet on a hard surface so that the smaller dividing line is on the bottom. Then, press the deeper dividing line with your index finger.
The tablet will break into two parts.

If the doctor does not prescribe otherwise, the medicine is usually taken as described below.
Adults
Formetic 1000 mg is suitable if higher doses of the medicine are necessary.
The recommended initial dose is ½ coated tablet of Formetic (1000 mg) per day (equivalent to 500 mg of metformin hydrochloride), taken during or after a meal.
The usual dose is 1 coated tablet of Formetic (1000 mg) taken twice a day (equivalent to 2000 mg of metformin hydrochloride), during or after a meal.
The maximum dose is 3 coated tablets of 1000 mg per day (equivalent to 3000 mg of metformin hydrochloride), taken in divided doses.
If the patient has impaired kidney function, the doctor may prescribe a lower dose.
Children over 10 years old and adolescents:
Formetic used as the only medicine or in combination with insulin:
The recommended initial dose is ½ coated tablet of Formetic (1000 mg) per day (equivalent to 500 mg of metformin hydrochloride), taken during or after a meal.
If necessary, the doctor may gradually increase the dose of Formetic to a maximum dose of 2 coated tablets of 1000 mg per day (equivalent to 2000 mg of metformin hydrochloride), taken in divided doses.
Coated tablets should be taken during or after a meal, with an adequate amount of fluid, and should not be chewed. If 2 or more coated tablets are taken per day, they should be taken at different times of the day, e.g., 1 coated tablet during or after breakfast and 1 coated tablet during or after lunch.
Pre-diabetes
The usual initial dose is 500 mg (½ coated tablet of Formetic 1000 mg) per day.
Depending on the clinical response, the dose can be increased to 1700 mg per day, given in divided doses.
Polycystic ovary syndrome
The usual dose is ½ coated tablet of Formetic 1000 mg (equivalent to 500 mg of metformin hydrochloride) three times a day.
If the patient feels that the effect of Formetic is too strong or too weak, they should consult their doctor.

Taking a higher dose of Formetic than recommended

In case of taking a higher dose of Formetic than recommended, the patient should immediately inform their doctor.
Overdose of Formetic does not cause hypoglycemia, but increases the risk of lactic acidosis.
Symptoms of impending lactic acidosis may be similar to metformin's gastrointestinal side effects: nausea, vomiting, diarrhea, abdominal pain with muscle cramps and weakness. In severe cases, muscle cramps, rapid breathing, decreased body temperature, acute kidney failure, and impaired consciousness or coma may also occur. These symptoms can develop within a few hours and require immediate hospital treatment.

Missing a dose of Formetic

In case of missing a dose of Formetic, the patient should take it at the time of the next scheduled dose and then continue with the prescribed dosing schedule. The patient should not take a double dose of the medicine to make up for the missed dose.

Stopping treatment with Formetic

In case of stopping treatment with Formetic, the patient should remember that poorly controlled, elevated blood glucose levels can cause damage to the eyes, kidneys, and blood vessels over a longer period.
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, Formetic can cause side effects, although not everybody gets them.
Side effects are assessed based on the following frequencies:

Formetic may very rarely cause (may occur in up to 1 in 10,000 patients) a very serious side effect called lactic acidosis (see "Warnings and precautions"). If this occurs, the patient should stop takingFormetic and immediately contact their doctor or the nearest hospital, as lactic acidosis can lead to coma.
Very common:
Nausea, vomiting, diarrhea, abdominal pain, and loss of appetite. These symptoms occur more frequently at the beginning of treatment and usually resolve on their own. To avoid gastrointestinal side effects, it is recommended to take Formetic in 2 or 3 divided doses during or immediately after meals. If these disorders persist, Formetic should be discontinued and the doctor consulted.
Common:
Taste disorders.
Very rare:
Severe metabolic disorders associated with lactic acidosis. Symptoms of such disorders may include vomiting and abdominal pain, rapid breathing, muscle cramps, severe fatigue, decreased body temperature, acute kidney failure, or impaired consciousness (see "Warnings and precautions"). Lactic acidosis requires immediate hospital treatment. If the patient suspects that lactic acidosis has occurred, they should immediately consult their doctor and stop taking Formetic.
Skin reactions, such as rash, itching, and urticaria.
Abnormal liver function test results or hepatitis, with possible jaundice (yellowing of the skin and eyes), resolving after discontinuation of Formetic.
Decreased absorption of vitamin B12, leading to anemia, glossitis, and paresthesia (tingling, burning, or numbness) in the limbs.

Children and adolescents

Limited information on side effects observed in children aged 10-16 and adolescents indicates that they have a similar nature and frequency as in adults.
