1. What Gliclazide Tablets are and what they are used for
Gliclazide is one of a group of medicines called sulfonylureas. It is an oral hypoglycaemic
medicine (blood sugar lowering drug). Gliclazide is used to keep blood sugar at the correct
level in adults with non-insulin dependent diabetes when it is not controlled by diet,
physical exercise and weight loss alone.
2. What you need to know before you take Gliclazide tablets
Do not take Gliclazide Tablets
• if you are allergic to gliclazide or any of the other ingredients of this medicine (listed in
section 6), to other medicines of the same group (sulfonylureas), to other related
medicines (hypoglycaemic sulfonamides),
• if you have insulin-dependent diabetes (type 1),
• if you have ketone bodies and sugar in your urine (this may mean you have keto-acidosis), a diabetic pre-coma or coma,
• if you have severe kidney or liver disease,
• if you are taking miconazole (a treatment for fungal infections) (see Taking other medicines),
• if you are breast-feeding (see Pregnancy and breast-feeding).
Gliclazide is not recommended for use in children.

Warnings and precautions
Talk to your doctor or pharmacist before taking Gliclazide
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;
Low blood sugar (hypoglycaemia) may occur if you:
• take meals irregularly or skip meals altogether, if you are fasting,
• are malnourished,
• change your diet,
• increase your physical activity and carbohydrate intake does not match this increase,
• drink alcohol, especially in combination with skipped meals,
• take other medicines or natural remedies at the same time,
• take too high doses of gliclazide,
• suffer from particular hormone-induced disorders (Functional disorders of the thyroid
gland, of the pituitary gland or adrenal cortex),
• 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 heartbeat, 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, 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
Symptom 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 (those acting on the central nervous system and ß-blockers).
Symptoms of high blood sugar (Hypeglycaemia) 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 reduced performance.
If these symptoms occurred you must contact your doctor or pharmacist.
While taking this medicine you should:
• follow a regular diet: it is important to eat regular meals, including breakfast and never
to miss or delay a meal,
• take your medicine regularly (see How to take Gliclazide Tablets),
• check your blood glucose regularly as recommended by your doctor.
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), contact your doctor
before taking this medicinal product.
Other medicines and Gliclazide Tablets:
Tell your doctor or pharmacist if you are taking, have recently taken any other medicines,
including medicines obtained without a prescription, as they may interact with your tablet.
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 (e.g. sulphonamides, chloramphenicol)
• 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 sugar 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
Gliclazide may increase the effects of medicines which reduce blood clotting (e.g. warfarin).

Pregnancy and breast-feeding
Do not take this medicine if you are pregnant, thinking of becoming pregnant or
breast-feeding. Tell your doctor if you are taking Gliclazide tablets and are breastfeeding or
planning to breast-feed your baby.
Driving and using machines
Provided your blood glucose levels are satisfactorily controlled on this medicine, your
ability to drive or use machines should not be affected. However, if your blood glucose
levels become too low, this could adversely affect your concentration, and therefore your
ability to perform these tasks.
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).
3. How to take Gliclazide Tablets
Always take this medicine exactly as your doctor has told you. Check with your doctor or
pharmacist if you are not sure.
Change in external factors (e.g. weight reduction, change in life style, stress) or
improvements in the blood sugar control may require changed gliclazide doses.
Gliclazide Tablets should be taken orally with food, either with breakfast or the first main
meal of the day. The usual dosage is as follows:
Adults and Elderly: The usual starting dose is 40 to 80mg (½ or 1 tablet) daily, adjusted
according to your response, up to a maximum of 320mg (four tablets) daily. Up to 160mg
(two tablets) can be taken at one time.
Your starting dose will be reduce if you are elderly or have liver or kidney problems.
If a combination therapy of Gliclazide 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.
Children: Gliclazide is not recommended for use in children.
If you take more Gliclazide Tablets 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.
If you forget to take Gliclazide Tablets
If you forget to take a dose, do not worry, just wait until it is time for your next dose. Do not
take a double dose to make up for a forgotten tablet.
If you stop taking Gliclazide Tablets
As the treatment for diabetes is usually life long, you should discuss with your doctor before
stopping this medicinal product. Stopping could cause high blood sugar (hyperglycaemia)
which increases the risk of developing complications of diabetes.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Low blood sugar (Hypoglycaemia).
The most commonly observed side effect is low blood sugar (hypoglycaemia). For
symptoms and signs see Section Warnings and Precautions.
If left untreated these symptoms could progress to drowsiness, loss of consciousness or
possibly coma. If an episode of low blood sugar is severe or prolonged, even if it is
temporarily controlled by eating sugar, you should seek immediate medical attention.
Other side effects
Digestive disorders: Abdominal pain, nausea, vomiting, indigestion, diarrhoea and
constipation. These effects are reduced when Gliclazide is taken with a meal as
Skin disorders: Skin reactions such as rash, redness, itching, hives, angioedema (rapid
swelling of tissues such as eyelids, face, lips, mouth, tongue or throat that may result in
breathing difficulty) have been reported. The rash may progress to widespread blistering or
peeling of the skin. Exceptionally, signs of severe hypersensitivity reactions (DRESS) have
been reported: initially as flu-like symptoms and a rash on the face then an extended rash
with a high temperature.
Blood disorders: Decrease in the number of cells in the blood (e.g. platelets, red and white
blood cells) which may cause paleness, prolonged bleeding, bruising, sore throat and
fever. These symptoms usually stop when the treatment is discontinued.
Liver disorders: There have been isolated reports of abnormal liver function which can
cause yellow skin and eyes. If you get this, see your doctor immediately. The symptoms
generally disappear if the drug is stopped. Your doctor will decide whether to stop your
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 (e.g.
jaundice) which in most cases disappeared after withdrawal of the sulfonylurea, but may
lead to life threatening liver failure in isolated cases.
