Warnings and precautions
You should observe the treatment plan prescribed by your doctor to achieve proper blood sugar levels. This
means, apart from regular tablet intake, you 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
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
In most cases the symptoms of low blood sugar vanish very quickly when you consume some form of sugar,
e.g. 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 (e.g. those acting on the central nervous system and beta blockers).
If you are in stress-situations (e.g. 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 or in special
stress situations). These may include thirst, frequent urination, dry mouth, dry itchy skin, skin infections and
If these symptoms occur, you must contact your doctor or pharmacist.
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

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),
antibiotics (e.g. sulphonamides, clarithromycin),
medicines to treat high blood pressure or heart failure (beta blockers, ACE-inhibitors such as captopril,
medicines to treat fungal infections (miconazole, fluconazole),
medicines to treat ulcers in the stomach or duodenum (H 2 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),

number of blood cells and allergic inflammation of the wall of blood vessels, reduction in blood sodium
