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

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.

taking the medicine as prescribed, you should contact your doctor

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.
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.
