The name of your medicine is Gliclazide 80 mg Tablets. The
active ingredient is gliclazide. Gliclazide is one of a group of

amount of sugar in your blood.
Gliclazide 80 mg Tablets are used to treat type II diabetes
mellitus in adults.
Do not take this medicine if:
• you have ever had an allergic reaction (allergic reactions
include mild symptoms such as itching and/or rash. More
severe symptoms include swelling of the face, lips, tongue
and/or throat with difficulty in swallowing or breathing) to
any of the ingredients of Gliclazide 80 mg Tablets or any

• you are suffering from severe injury, infection or
undergoing major surgery;
• you are taking miconazole (a treatment for fungal
infections)(see Taking other medicines).
Take special care with this medicine and tell you
doctor or pharmacist if:
• you have liver or kidney problems;
• you are experiencing the symptoms of low blood sugar
(such as sweating, pallor, hunger, faster heart beat and
feeling unwell).
Warnings and precautions
Follow your doctor’s advice about diet and treatment. This is to
reduce the chances of very low blood sugar (hypoglycaemia).
Make sure your doctor knows if:
• you have an operation, a serious injury, fever or infection,
difficulty in eating;
• you are planning a pregnancy or become pregnant;
• you are taking any of the medicines listed in Taking
other medicines.
Tell your dentist about your treatment.
Dietary advice
This medicine may cause episodes of low blood sugar
This is more likely if:
• you are on a strict diet;
• your diet is poorly balanced;

• you are taking prolonged or strenuous exercise;
• you drink alcohol;
• you are taking several medicines for high blood sugar (See
Taking other medicines).
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 spread 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 symptoms recur.
