You should observe the treatment plan prescribed by your doctor to achieve proper blood sugar levels. This means, apart from regular tablet intake, to observe the dietary regimen, have physical exercise and, where necessary, reduce weight.

During gliclazide treatment regular monitoring of your blood (and possibly urine) sugar level and also your glycated haemoglobin (HbA1c) is necessary.

In the first few weeks of treatment the risk of having reduced blood sugar levels (hypoglycaemia) may be increased. So particularly close medical monitoring is necessary.

Low blood sugar (Hypoglycaemia) may occur:

• if you take meals irregularly or skip meals altogether,
• if you are fasting,
• if you are malnourished,
• if you change your diet,
• if you increase your physical activity and carbohydrate intake does not match this increase,
• if you drink alcohol, especially in combination with skipped meals,
• if you take other medicines or natural remedies at the same time,
• if you take too high doses of gliclazide,
• if you suffer from particular hormone-induced disorders (functional disorders of the thyroid gland, of the pituitary gland or adrenal cortex),
• if your kidney function or liver function is severely decreased.

If you have low blood sugar you may have the following symptoms:

headache, intense hunger, nausea, vomiting, weariness, sleep disorders, restlessness, aggressiveness, poor concentration, reduced alertness and reaction time, depression, confusion, speech or visual disorders, tremor, sensory disturbances, dizziness, and helplessness.

The following signs and symptoms may also occur: sweating, clammy skin, anxiety, fast or irregular heart beat, high blood pressure, sudden strong pain in the chest that may radiate into nearby areas (angina pectoris).

If blood sugar levels continue to drop you may suffer from considerable confusion (delirium), develop convulsions, lose self control, your breathing may be shallow and your heart beat slowed down, you may become unconscious.

In most cases the symptoms of low blood sugar vanish very quickly when you consume some form of sugar, for instance glucose tablets, sugar cubes, sweet juice, sweetened tea.

You should therefore always carry some form of sugar with you (glucose tablets, sugar cubes). Remember that artificial sweeteners are not effective. Please contact your doctor or the nearest hospital if taking sugar does not help or if the symptoms recur.

Symptoms of low blood sugar may be absent, less obvious or develop very slowly or you are not aware in time that your blood sugar level has dropped. This may happen if you are an elderly patient taking certain medicines (for instance those acting on the central nervous system and beta blockers).

If you are in stress-situations (accidents, surgical operations, fever etc.) your doctor may temporarily switch you to insulin therapy.

Symptoms of high blood sugar (hyperglycaemia) may occur when gliclazide has not yet sufficiently reduced the blood sugar, when you have not complied with the treatment plan prescribed by your doctor, if you take St John’s Wort (Hypericum perforatum) preparations (see section “Other medicines and Diamicron 30 mg”), or in special stress situations. These may include thirst, frequent urination, dry mouth, dry itchy skin, skin infections and reduced performance.

If these symptoms occur, you must contact your doctor or pharmacist.

Blood glucose disturbance (low blood sugar and high blood sugar) can occur when gliclazide is prescribed at the same time than medicines belonging to a class of antibiotics called fluoroquinolones, especially in elderly patients. In this case, your doctor will remind you the importance of monitoring your blood glucose.

If you have a family history of or know you have the hereditary condition glucose-6-phosphate dehydrogenase (G6PD) deficiency (abnormality of red blood cells), lowering of the haemoglobin level and breakdown of red blood cells (haemolytic anaemia) can occur. Contact your doctor before taking this medicinal product.

Cases of acute porphyria have been described with some other sulfonylurea drugs, in patients who have porphyria (inherited genetic disorders with accumulation in the body of porphyrins or porphyrin precursors).

Diamicron 30 mg MR is not recommended for use in children due to a lack of data.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

The blood sugar lowering effect of gliclazide may be strengthened and signs of low blood sugar levels may occur when one of the following medicines is taken:

• other medicines used to treat high blood sugar (oral antidiabetics, GLP-1 receptor inhibitors or insulin),
• antibiotics (sulfonamides, clarithromycin),
• medicines to treat high blood pressure or heart failure (beta blockers, ACE-inhibitors such as captopril, or enalapril),
• medicines to treat fungal infections (miconazole, fluconazole),
• medicines to treat ulcers in the stomach or duodenum (H₂ receptor antagonists),
• medicines to treat depression (monoamine oxidase inhibitors),
• painkiller or antirheumatics (phenylbutazone, ibuprofen),
• medicines containing alcohol.

The blood glucose lowering effect of gliclazide may be weakened and raised blood sugar levels may occur when one of the following medicines is taken:

• medicines to treat disorders of the central nervous system (chlorpromazine),
• medicines reducing inflammation (corticosteroids),
• medicines to treat asthma or used during labour (intravenous salbutamol, ritodrine and terbutaline),
• medicines to treat breast disorders, heavy menstrual bleeding and endometriosis (danazol),
• St John’s Wort -Hypericum perforatum-preparations.

Blood glucose disturbance (low blood sugar and high blood sugar) can occur when a medicine belonging to a class of antibiotics called fluoroquinolones is taken at the same time than Diamicron 30mg, especially in elderly patients.

Diamicron 30 mg MR may increase the effects of medicines which reduce blood clotting (e.g. warfarin).

Consult your doctor before you start taking another medicinal product. If you go into hospital tell the medical staff you are taking Diamicron 30 mg MR.

Diamicron 30 mg MR can be taken with food and non-alcoholic drinks.

Drinking alcohol is not recommended as it can alter the control of your diabetes in an unpredictable manner.

Diamicron 30 mg MR is not recommended for use during pregnancy. If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

You must not take Diamicron 30 mg MR while you are breastfeeding.

Your ability to concentrate or react may be impaired if your blood sugar is too low (hypoglycaemia), or too high (hyperglycaemia) or if you develop visual problems as a result of such conditions. Bear in mind that you could endanger yourself or others (for instance when driving a car or using machines). Please ask your doctor whether you can drive a car if you:

• have frequent episodes of low blood sugar (hypoglycaemia),
• have few or no warning signals of low blood sugar (hypoglycaemia).

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The dose is determined by the doctor, depending on your blood and possibly urine sugar levels.

Change in external factors (weight reduction, change in life style, stress) or improvements in the blood sugar control may require changed gliclazide doses.

The recommended daily dose is one to four tablets (maximum 120 mg) in a single intake at breakfast time. This depends on the response to treatment.

Diamicron 30 mg is for oral use. Take your tablet(s) with a glass of water at breakfast time (and preferably at the same time each day). Swallow your tablets whole. Do not chew them.

You must always eat a meal after taking your tablet(s).

If a combination therapy of Diamicron 30 mg MR with metformin, an alpha glucosidase inhibitor, a thiazolidinedione, a dipeptidyl peptidase-4 inhibitor, a GLP-1 receptor agonist or insulin is initiated your doctor will determine the proper dose of each medicine individually for you.

If you notice that your blood sugar levels are high although you are taking the medicine as prescribed, you should contact your doctor or pharmacist.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
