1. What Sukkarto SR is and what it is used for

Sukkarto SR 1000mg prolonged release tablets contain the active ingredient metformin hydrochloride. Each tablet contains 1000 mg of metformin hydrochloride. Metformin belongs to a group of drugs called biguanides which are used in the treatment of diabetes.

Sukkarto SR is used for the treatment of Type 2 (non-insulin dependent) diabetes mellitus particularly in overweight patients, where diet and exercise changes alone have not been sufficient to control it. In type 2 diabetes, there is too much sugar (glucose) in the blood because pancreas does not produce enough insulin or because it produces insulin that does not work properly.

Insulin is a hormone that enables body tissues to take glucose from the blood and use it for energy or fat storage for future use. People with Type 2 diabetes do not make enough insulin in their pancreas, or their body does not respond properly to the insulin it does make. This causes a build-up of glucose in the blood which can cause a number of serious long-term problems so it is important that you continue to take your medicine, even though you may not have any obvious symptoms. Sukkarto SR makes the body more sensitive to insulin and helps return to the normal way your body uses glucose.

Sukkarto SR Prolonged release tablets are specially made to release the drug slowly in your body and therefore are different to many other types of tablet containing metformin.

Adults

Your doctor can prescribe Sukkarto SR for you to take on its own, or in combination with other oral antidiabetic medicines, or insulin.

2. Before you take Sukkarto SR

Do not take Sukkarto SR

•    if you are allergic (hypersensitive) to metformin or to any of the ingredients in this medicine.

•    if you have ketosis (this is a symptom of uncontrolled diabetes in which substances called “ketone bodies” accumulate in the blood; you may notice that your breath has an unusual, fruity odour).

•    if you have had serious complications with your diabetes or other serious conditions which resulted in rapid weight loss, nausea, vomiting or dehydration and you have fainted or suffered a coma due to your diabetes.

•    if you have any long-term problems with your liver or kidneys.

•    if you are suffering from severe infection or have recently suffered a severe injury.

•    if you have been treated for heart problems or have recently had a heart attack or have problems with your circulation (e.g. frequent cramp in your calves or leg ulcers that do not heal) or breathing difficulties.

•    if you drink alcohol.

•    if you are under the age of 18 years.

Take special care with Sukkarto SR

If you have diabetes you should have your blood or urine tested for sugar regularly. You should return to your doctor at least once a year to check the function of your kidneys (more often if you are elderly or if you have kidney problems).

Sukkarto SR may cause a very rare, but serious complication called lactic acidosis, particularly if your kidneys are not working properly. The risk of lactic acidosis is also increased with uncontrolled diabetes, prolonged fasting or alcohol intake. Symptoms of lactic acidosis are vomiting, bellyache (abdominal pain) with muscle cramps, a general feeling of not being well with severe tiredness, and difficulty in breathing. If this happens to you, you may need immediate hospital treatment, as lactic acidosis may lead to coma. Stop taking Sukkarto SR immediately and contact a doctor or the nearest hospital straight away (see also under '4. Possible side effects').

If you need to have an X-ray examination tell your doctor that you take Sukkarto SR as you may need to stop taking it for few days afterwards.

Tell your doctor if surgery is planned. Treatment with Sukkarto SR should be stopped 2 days before surgery until at least 2 days following surgery.

You should continue your diet during treatment with Sukkarto SR with an even intake of carbohydrate over the day. If you are overweight continue your energy-restricted diet under medical supervision.

Normal kidneys are essential for the treatment with Sukkarto SR because of the risk of developing lactic acidosis. Tests will be done to check your kidney function at least once a year or more frequently if you are elderly, or when starting treatment for high blood pressure.

Taking Sukkarto SR alone does not normally cause low blood sugar levels (hypoglycaemia). Taking Sukkarto SR in combination with medicines called sulphonylureas, meglitinides, insulin or other treatments for diabetes may cause low blood sugar levels with symptoms such as sweating, fainting, dizziness orweakness, so in this case you should take extra care when driving or operating machinery.

You may see some remains of your tablets in your stools. Do not worry - this is normal for this type of tablet.

Do not stop taking this medicine without speaking to your doctor.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines including medicines obtained withouta prescription.

If you are taking any of the following medicines, your blood sugar levels may need to be checked more often and your dose adjusted:

•    Steroids such as prednisolone, mometasone, beclometasone,

•    Sympathomimetics such as epinephrine used to treat heart attack or low blood pressure,

•    Diuretics (water tablets) such as bendroflumethiazide,

•    ACE inhibitors such as lisinopril, enalapril, captopril.

Taking Sukkarto SR with food and drink

The tablets should be swallowed whole with a glass of water during or immediately after meals. Avoid drinking alcohol while taking Sukkarto SR, as this will increase the risk of lactic acidosis (see under “4. Possible side effects”).

Pregnancy and breast-feeding

Do not take Sukkarto SR if you are pregnant or breastfeeding. Tell your doctor immediately if you think you are pregnant orare breast-feeding.

Driving and using machines:

Sukkarto SR taken on its own does not cause 'hypos' (symptoms of low blood sugar or hypoglycaemia, such as faintness, confusion and increased sweating) and therefore should not affect your ability to drive or use machinery.

You should be aware, however, that Sukkarto SR taken with other antidiabetic medicines can cause hypos, so in this case you should take extra care when driving or operating machinery.

3. How to take Sukkarto SR

Always take Sukkarto SR exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.

Swallow the tablets whole with a glass of water, do not chew. The usual dose is:

Adults'. The usual starting dose is one 500 mg tablet daily with your evening meals. After two weeks your doctor may increase the dose to a maximum of 2000 mg per day. In some cases, your doctor may recommend that you take the tablet twice a day. Always take the tablets with food.

Combination with insulin'. When taking Sukkarto SR with insulin, the usual dose is one 500mg tablet once a day, while insulin dosage is adjusted on the basis of blood sugar measurements.

Elderly. The starting dose will be determined after tests have been carried out on your kidney function.

Children and adolescents below 18 years'. The use of the medication is not recommended.

Your doctor will test your blood glucose and your kidney function at intervals while you are taking Sukkarto SR to make sure you are taking the right dose. This is especially important when you start taking other new medicines at the same time as Sukkarto SR.
