Eucreas tablets contain the active ingredient metformin hydrochloride, an antiviral medicine that is used to treat type 2 diabetes in adults.

Why does diabetes occur? Why should you need to treat diabetes?

Type 2 diabetes is the most common type of diabetes, it means that the insulin in your body is unable to ensure the glucose produced by your food is absorbed and converted into fuel for your body. This makes your blood sugar level rise which is dangerous and can cause the body to shut down. Usually, Type 2 diabetes can be managed well with medication and in most cases, insulin is not needed until the medicines no longer work. Exercise and a low sugar diet also have an important role to play in the management of diabetes. There is a range of medicines available to treat type 2 diabetes, often metformin hydrochloride is the first one you try, but you may end up needing a combination of medicines to ensure you get the right treatment to help control your diabetes and enable you to lead a normal life.

What is Eucreas?

Eucreas is an oral antidiabetic medicine that comes in the form of a film-coated tablet. The tablet contains two active ingredients:

  • Vildagliptin which makes the pancreas produce more insulin and less glucagon – (glucagon triggers the liver to make sugar and increases the blood sugar level);
  • Metformin hydrochloride which helps the body to use the insulin that it already has to be more effective. Eucreas tablets are available in two different strengths: 50 mg/850 mg; 50 mg/1000 mg.

How to use Eucreas tablets to treat diabetes

Eucreas is used to treat type 2 diabetes in adults. Type 2 diabetes is when the insulin your pancreas makes cannot work properly, or your pancreas cannot make enough insulin. Eucreas works to regulate the blood sugar level in your body to help prevent complications from diabetes.

Eucreas tablets are often taken alongside a diet and exercise plan, you must follow all the instructions of your doctor if you want to lead a normal healthy life and maximise the benefits of Metformin and Vidaglipin.

Always follow the instructions of your doctor when it comes to taking medicine as doses and methods can vary according to what an individual person needs. As a general guide, take Eucreas as follows.

Eucreas comes in tablet form:

  • Swallow the tablet whole with a glass of water;
  • Take the tablet just after food to minimize the risk of getting an upset stomach.

What is the correct dosage for Eucreas tablets?

Eucreas tablets are available in two different sized dosages:

50 mg/850mg;

50 mg/1000mg.

The correct dose for you will depend on your condition.

It is always important to take the dose that your doctor prescribes as although a dose is listed on the medication leaflet, this may need to vary for a variety of reasons, for example, any other health issues you have or any other medication you are taking. If you are unsure about the dose check with your doctor or pharmacist.

  • One tablet, twice a day with food;
  • Take one tablet with your breakfast and one with your evening meal;

You may take Eucreas alongside other medicines to treat your diabetes, your doctor will be able to guide you with this:
