What is in this leaflet
1. What Diamicron MR is and what it is used for

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 stresssituations (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 MR”) or
in special stress situations. These may include thirst, frequent
urination, dry mouth, dry itchy skin, skin infections and reduced

Diamicron MR is a medicine that reduces blood sugar levels (oral
antidiabetic medicine belonging to the sulfonylurea group).

mellitus) in adults, when diet, exercise and weight loss alone do not
have an adequate effect on keeping blood sugar at the correct

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
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.

Children and adolescents
Diamicron MR is not recommended for use in children due to a lack
of data.
Other medicines and Diamicron MR
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),

Warnings and precautions

medicines to treat fungal infections (miconazole, fluconazole),

Talk to your doctor before taking Diamicron MR. 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.

medicines to treat ulcers in the stomach or duodenum (H2
receptor antagonists),

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:

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

if you take meals irregularly or skip meals altogether,

medicines reducing inflammation (corticosteroids),

if you are fasting,

if you are malnourished,

medicines to treat asthma or used during labour (intravenous
salbutamol, ritodrine and terbutaline),

if you change your diet,

if you increase your physical activity and carbohydrate intake
does not match this increase,

medicines to treat breast disorders, heavy menstrual bleeding
and endometriosis (danazol),

St John’s Wort –Hypericum perforatum- preparations.

if you drink alcohol, especially in combination with skipped

if you take other medicines or natural remedies at the same

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
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.

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 MR
Tablets, especially in elderly patients.
Diamicron MR may increase the effects of medicines which reduce
blood clotting (warfarin).
Consult your doctor before you start taking another medicinal
product. If you go into hospital tell the medical staff you are taking
Diamicron MR.
Diamicron MR with food, drink and alcohol
Diamicron 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.
Pregnancy and breastfeeding
Diamicron 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 MR while you are breastfeeding.

Driving and using machines
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

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 MR 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 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 take more Diamicron MR than you should
If you take too many tablets, contact your doctor or the nearest
hospital Accident & Emergency department immediately. The signs
of overdose are those of low blood sugar (hypoglycaemia)
described in Section 2. The symptoms can be helped by taking
sugar (4 to 6 lumps) or sugary drinks straight away, followed by a
substantial snack or meal. If the patient is unconscious immediately
inform a doctor and call the emergency services. The same should
be done if somebody, for instance a child, has taken the product
unintentionally. Unconscious patients must not be given food or
It should be ensured that there is always a pre-informed person that
can call a doctor in case of emergency.

Eye disorders
Your vision may be affected for a short time especially at the start of
treatment. This effect is due to changes in blood sugar levels.
As for other sulfonylureas, the following adverse events have been
observed: cases of severe changes in the number of blood cells
and allergic inflammation of the wall of blood vessels, reduction in
blood sodium (hyponatraemia), symptoms of liver impairment (for
instance jaundice) which in most cases disappeared after
withdrawal of the sulfonylureas, but may lead to life-threatening liver
failure in isolated cases.
