What Dacadis MR is and what it is used for

Dacadis MR is a medicine to reduce blood sugar levels (oral antidiabetic medicine belonging
to the sulphonylurea group of medicines).
Dacadis MR is used in a certain form of diabetes (type 2 diabetes mellitus) in adults, when
diet, exercise and weight loss alone do not have an adequate effect.

What you need to know before you take Dacadis MR

Do not take Dacadis MR
if you are allergic to gliclazide or to any of the other ingredients of this medicine (listed
in section 6), or to other medicines of the same group (sulphonylureas), or to other
related medicines (hypoglycaemic sulphonamides),
if you have insulin-dependent (type 1) diabetes,
if you have ketone bodies and sugar in the urine (this may mean you have diabetic ketoacidosis), diabetic pre-coma or coma,
if you have severe kidney or liver disease,
if you are taking medicines to treat fungal infections (miconazole – see section ‘Other
medicines and Dacadis MR’),
if you are breast feeding.
If you think any of the above situations applies to you, tell your doctor or pharmacist.
Warnings and precautions
This medicine should be used only if you are likely to have regular food intake (including
breakfast). It is important to have a regular carbohydrate intake due to the increased risk of
low blood sugar level (hypoglycaemia) if a meal is delayed or skipped, if an inadequate
amount of food is consumed or if the food is low in carbohydrate.

During gliclazide treatment regular monitoring of your blood (and possibly urine) sugar level
is necessary. Your doctor may also take blood tests to monitor your glycated haemoglobin
You should observe the treatment plan prescribed by your doctor in order to achieve the
recommended blood sugar levels. This means regular tablet intake in addition to a dietary
regimen and physical exercise and, where necessary, reduced weight.
In the first few weeks of treatment the risk of having reduced blood sugar levels
(hypoglycaemia) may be increased. Therefore it is vital that you are carefully monitored by
your doctor.
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 without an appropriate increase in carbohydrate
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 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 suffer from low blood sugar you may have the following symptoms: headache, intense
hunger, paleness, weakness, exhaustion, nausea, vomiting, weariness, sleepiness, sleep
disorders, restlessness, aggressiveness, impaired concentration, reduced alertness and reaction
time, depression, confusion, speech or visual disorders, tremor, sensory disturbances,
dizziness, helplessness. The following signs and symptoms may also occur: sweating, clammy
skin, anxiety, fast or irregular heartbeat, high blood pressure, and sudden strong pain in the
chest that may radiate into nearby areas (angina pectoris).
If your blood sugar levels continue to drop you may suffer from considerable confusion
(delirium), develop convulsions, lose self-control, breathing may be shallow and your heart
beat slowed down, you may fall into unconsciousness possibly resulting in coma.
In most cases the symptoms of low blood sugar vanish very quickly when you consume some
form of sugar, e.g. sugar cubes, sweet juice, sweetened tea. You should therefore always take
some form of sugar with you (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.
It is possible that symptoms of low blood sugar may be absent, that they develop slowly or
that you do not realise in time that your blood sugar level has dropped.
This may happen if you are an elderly patient taking certain medicines (e.g. those acting on
the central nervous system and beta blockers). It may also happen when you suffer from

certain disorders of the endocrine system (e.g. certain disorders of thyroid function and
anterior pituitary or adrenocortical insufficiency).
If you are in stress-situations (e.g. accidents, surgical operations, infections with 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 taken the medicine in the way your
doctor has told you or in special stress situations. Signs of high blood sugar may include
thirst, frequent urination, dry mouth, dry itchy skin, skin infections and diminished
performance. Contact your doctor or pharmacist if you experience any of these.
If you have a family history of or know that you have the hereditary condition glucose-6phosphate 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.
Children and adolescents
Dacadis MR is not to be used for the treatment of diabetes in children and adolescents under
18 years of age.
Other medicines and Dacadis MR
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
medicines, including medicines obtained without a prescription.
The effectiveness and safety of Dacadis MR may be affected if this medicine is taken at the
same time as certain other medicines. Conversely, other medicines may be affected if they are
taken at the same time as Dacadis MR.
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
agonists or insulin),
antibacterial medicines (e.g. sulphonamides, 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 indigestion and ulcers in the stomach or duodenum (H2 receptor
antagonists such as ranitidine),
medicines to treat depression (monoamine oxidase inhibitors such as selegiline,
painkillers or antirheumatics (ibuprofen, phenylbutazone),
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:
medicine to treat disorders of the central nervous system (chlorpromazine),
medicines reducing inflammation (glucocorticoids such as hydrocortisone,
medicine to treat asthma (salbutamol when given by injection),
medicines used during labour (ritodrine and terbutaline given by injection),


medicine to treat breast disorders, heavy menstrual bleeding and endometriosis

Gliclazide may increase the effect of warfarin (a medicine that inhibits blood clotting).
Consult your doctor before you start taking another medicinal product. If you go into hospital
tell the medical staff you are taking Dacadis MR.
Dacadis MR with food, drink and alcohol
Dacadis 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 and can even lead to coma.
Pregnancy and breast-feeding
Dacadis MR is not recommended for use during pregnancy.
You must not take Dacadis MR while you are breastfeeding.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a
baby, ask your doctor or pharmacist for advice before taking this medicine. Your doctor may
prescribe a more suitable treatment for you.
Driving and using machines
Dacadis MR has not known influence on the ability to drive and use machines. However, 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. This can occur more often at the beginning of treatment with Dacadis MR.
Bear in mind that you could endanger yourself or others (e.g. when driving a car or using
machines). Please ask your doctor whether you can drive a car if you:
have frequent episodes of hypoglycaemia,
have fewer or no warning symptoms of hypoglycaemia.
Dacadis MR contains lactose.
If you have been told by your doctor that you have intolerance to some sugars, contact your
doctor before taking this medicinal product.

How to take Dacadis MR

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 of Dacadis MR is determined by the doctor, depending on your blood and possibly
urine sugar levels. Changes in external factors (e.g. weight reduction, change in life style,
stress) or improvements in the blood sugar control may require changed gliclazide doses.
The recommended starting dose is one tablet (30 mg) once daily. The usual dose can vary
from one to a maximum of four tablets (30 to 120 mg) taken at the same time, with breakfast.
This depends on the response to treatment.
If blood glucose is not adequately controlled, your doctor may increase your dose in
successive steps usually not less than 1 month apart.

If a combination therapy of Dacadis MR with metformin, an alpha glucosidase inhibitor, a
thiazolidinedione, a 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 still high or have become too low although you
are taking the medicine as instructed, contact your doctor or pharmacist.
Route and method of administration
Oral use.
Swallow your tablets whole with a glass of water while having your breakfast, preferably at
the same time each day. You must always eat a meal after or while taking your tablets. It is
also important not to skip a meal when you are on Dacadis MR.
Do not crush or chew your tablets. If you do, there is a danger you could overdose because the
medicine will be absorbed into your body too quickly.
Use in children and adolescents
Dacadis MR is not recommended for use in children and adolescents as there is no data
If you take more Dacadis 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, e.g. a child, has taken the product unintentionally.
Unconscious patients must not be given food or drink.
It should be ensured that there is always a pre-informed person that can call a doctor in case
of emergency.
If you forget to take Dacadis MR
If you forget to take a dose take the next dose at the usual time.
Do not take a double dose to make up for a forgotten tablet.
If you stop taking Dacadis MR If you interrupt or stop the treatment you should be aware
that your blood sugar control will deteriorate. Stopping could lead to high blood sugar
(hyperglycaemia), which increases the risk of developing complications of diabetes. If any
change is necessary it is important to contact your doctor first.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
