1. What is Melkart Duo and what is it used for
The active substances of Melkart Duo are vildagliptin and metformin, which belong to the group of oral antidiabetic medicines.
Melkart Duo is used to treat adult patients with type 2 diabetes mellitus. This type of diabetes is also called non-insulin-dependent diabetes.
Type 2 diabetes is a disease in which the body does not produce enough insulin or the insulin produced by the body does not work properly. Type 2 diabetes can also develop when the body produces too much glucagon.
Both insulin and glucagon are produced in the pancreas. Insulin helps to lower blood sugar levels, especially after a meal. Glucagon is a substance that stimulates the production of sugar in the liver and increases blood sugar levels.
How Melkart Duo works
Both active substances, vildagliptin and metformin, help to maintain a normal blood sugar level.
Vildagliptin works by stimulating the pancreas to produce insulin and reducing the production of glucagon. Metformin helps the body to use insulin better.
It has been shown that the medicine lowers blood sugar levels, which can help to prevent complications in diabetes.
2. Important information before taking Melkart Duo
When not to take Melkart Duo:
- if the patient is allergic to vildagliptin, metformin, or any of the other ingredients of this medicine (listed in section 6). If the patient thinks they may be allergic to any of these ingredients, they should consult their doctor before taking Melkart Duo;
if the patient has uncontrolled diabetes, for example, severe hyperglycemia (high blood sugar), nausea, vomiting, diarrhea, sudden weight loss, lactic acidosis (see "Risk of lactic acidosis" below) or diabetic ketoacidosis. Diabetic ketoacidosis is a disease in which substances called ketone bodies accumulate in the blood and can lead to diabetic coma. Symptoms include abdominal pain, rapid and deep breathing, drowsiness or unusual fruity breath odor;
- if the patient has recently had a heart attack or has heart failure or severe circulatory disorders or breathing difficulties, which may be a sign of heart failure;
- if the patient has significantly reduced kidney function;
- if the patient has a severe infection or is severely dehydrated (has lost a lot of water from the body);
- if the patient is to undergo a contrast radiological examination (a special type of examination that requires the injection of a contrast agent). For more information, see also section "Warnings and precautions";
- if the patient has liver disease;
- if the patient drinks excessive amounts of alcohol (every day or from time to time);
- if the patient is breastfeeding (see also section "Pregnancy and breastfeeding");
- if the patient has previously been diagnosed with intolerance to certain sugars, the patient should consult their doctor before taking the medicine.
Warnings and precautions
Risk of lactic acidosis
Melkart Duo may rarely cause a very serious side effect called lactic acidosis, especially if the patient has kidney problems. The risk of lactic acidosis also 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., acute severe heart disease).
If any of the above conditions apply to the patient, they should consult their doctor for more detailed instructions.
The patient should temporarily stop taking Melkart Duo if they experience a condition that may lead to dehydration
(significant loss of water from the body), such as severe vomiting, diarrhea, fever, or heat stroke, or if the patient drinks less fluid than usual. The patient should consult their doctor for more detailed instructions.
The patient should stop taking Melkart Duo and immediately consult 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.
Melkart Duo does not replace insulin. Therefore, the patient should not take Melkart Duo to treat type 1 diabetes.
Before starting treatment with Melkart Duo, the patient should discuss it with their doctor, pharmacist, or nurse if they have or have had pancreatitis.
Before starting treatment with Melkart Duo, the patient should consult their doctor, pharmacist, or nurse if they are taking a sulfonylurea, a type of antidiabetic medicine.
The doctor may want to reduce the dose of sulfonylurea taken with Melkart Duo to avoid low blood sugar (hypoglycemia).
If the patient has taken vildagliptin before but had to stop taking it due to liver disease, they should not take this medicine.
Diabetic skin changes are a common complication of diabetes. The patient should follow their doctor's or nurse's advice on skin and foot care. It is also recommended that the patient pay special attention to the occurrence of new blisters or ulcers while taking Melkart Duo. If they occur, the patient should consult their doctor promptly.
If the patient is to undergo major surgery, they should not take Melkart Duo during the surgery and for some time after it. The doctor will decide when the patient should stop and resume treatment with Melkart Duo.
Before starting treatment with Melkart Duo and at three-month intervals during the first year of treatment, and then periodically, the patient should have liver function tests. This will help to detect any signs of increased liver enzyme activity as soon as possible.
During treatment with Melkart Duo, the doctor will check the patient's kidney function at least once a year or more often if the patient is elderly and/or has worsening kidney function.
The doctor will regularly assess the patient's blood and urine sugar levels.
Melkart Duo contains lactose and sodium
If the patient has been diagnosed with intolerance to certain sugars, they should consult their doctor before taking this medicine.
This medicine contains less than 1 mmol of sodium (23 mg) per dose, which means it is considered "sodium-free".

Melkart Duo and other medicines
If the patient is to be injected with a contrast agent containing iodine, for example, for an X-ray examination or computed tomography, they should stop taking Melkart Duo before or at the latest at the time of the injection. The doctor will decide when the patient should stop and resume treatment with Melkart Duo.
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 sugar checks and kidney function tests or dose adjustments of Melkart Duo by their doctor. It is especially important to inform about the following medicines:
- corticosteroids, usually used to treat inflammatory conditions
- beta-2-adrenergic receptor agonists, usually used to treat respiratory disorders;
- other medicines used to treat diabetes;
- diuretics;
- medicines used to treat pain and inflammation (NSAIDs and COX-2 inhibitors, such as ibuprofen and celecoxib);

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

When and how to take Melkart Duo
