1. WHAT GLUCIENT SR IS AND WHAT IS IT
Glucient SR prolonged release tablets contain
the active ingredient metformin hydrochloride
and belong to a group of medicines called
biguanides, used in the treatment of diabetes
Glucient SR is used for the treatment of Type 2
(non-insulin dependant) diabetes mellitus when
diet and exercise changes alone have not been
enough to control blood glucose (sugar).
Insulin is a hormone that enables body tissues to
take glucose from the blood and to use it for
energy or for storage for future use. People with
Type 2 diabetes do not make enough insulin in
their pancreas or their body does not respond
properly to the insulin it does make. This causes
a build-up of glucose in the blood which can
cause a number of serious long-term problems
so it is important that you continue to take your
medicine, even though you may not have any
obvious symptoms. Glucient SR makes the body
more sensitive to insulin and helps return to
normal the way your body uses glucose.
Glucient SR is associated with either a stable
body weight or modest weight loss.
Glucient SR Prolonged Release Tablets are
specially made to release the drug slowly in your
body and therefore are different to many other
types of tablet containing metformin.
2. WHAT YOU NEED TO KNOW BEFORE
YOU TAKE GLUCIENT SR
Do NOT take Glucient SR if:
• you are allergic to metformin or to any of the
other ingredients which are listed later on in
the leaflet (see under section ‘6. Further
• you have ketosis (this is a symptom of
uncontrolled diabetes in which substances
called ‘ketone bodies’ accumulate in the
blood- you may notice that your breath has an
unusual, fruity odour).
• you have long-term kidney or liver problems.
• you have had serious complications with your
diabetes or other serious conditions which
resulted in rapid weight loss, nausea, vomiting
• you have a severe infection or have recently
suffered a severe injury
• you have been treated for heart problems or
have recently had a heart attack or have severe
circulatory problems or breathing difficulties.
• you are a heavy drinker of alcohol.
• you are under 18 years of age.
Warnings and precautions
After you have started taking your medicine:
If you have diabetes you should have your blood
or urine tested for sugar regularly. You should
return to the doctor at least once a year to check
the function of your kidneys (more often if you
are elderly or if you have kidney problems).
If you start to lose weight unexpectedly or
suffer severe nausea or vomiting, uncontrolled
rapid breathing or abdominal pains, stop
taking the medicine and tell your doctor
straight away. This can be a sign of a rare, but
serious, complication with your diabetes
called ‘ lactic acidosis’ which means there is
too much acid in the blood (see also under
section ‘4. Possible side effects’).
You may see some remains of the tablets in your
stools. Do not worry- this is normal for this type
of tablet. If you need to have an X-ray
examination involving the injection of a dye, tell
the doctor that you take Glucient SR as you may
need to stop taking it for a few days afterwards.
Tell your doctor if you are going to have an
operation under general anaesthetic, as you may
need to stop taking Glucient SR for a couple of
days before and after the procedure.
You should continue to follow any dietary advice
that your doctor has given you and you should
make sure that you eat carbohydrates regularly
throughout the day.
Do not stop taking this medicine without
speaking to your doctor.
Other medicines and Glucient SR
Please tell your doctor or pharmacist if you are
taking or have recently taken any other
medicines, including medicines obtained without
If you are taking any of the following medicines,
your blood sugar levels may need to be checked
more often and your dose adjusted:
• Steroids such as prednisolone, mometasone,
• Diuretics (water tablets) such as furosemide.
• Sympathomimetic medicines including
epinephrine and dopamine used to treat heart
attacks and low blood pressure.
Epinephrine is also included in some dental
You should avoid drinking alcohol and using
alcohol-containing medicines as this will increase
the risk of lactic acidosis ( see under section ‘4.
Possible side effects’).
Glucient SR with food and drink
You should take Glucient SR with or immediately
Pregnancy and breast-feeding
Do not take Glucient SR if you are pregnant or
Ask your doctor or pharmacist for advice before
taking any medicine.
Driving and using machines
Glucient SR taken on its own does not cause
‘hypos’ (symptoms of low blood sugar or
hypoglycaemia, such as faintness, confusion and
increased sweating) and therefore should not
affect your ability to drive or use machinery.
You should be aware, however, that Glucient SR
taken with other antidiabetic medicines can
cause hypos, so in this case you should take
extra care when driving or operating machinery.
Glucient SR contains sodium
This medicinal product contains up to 1.9 mmol
(or 41.4mg) sodium per dose. To be taken into
consideration by patients on a controlled sodium
3. How to take Glucient SR
Your doctor may prescribe Glucient SR for you to
take on its own, or in combination with other oral
antidiabetic medicines or insulin.
Always take this medicine exactly as your doctor
or pharmacist has told you. You should check
with your doctor or pharmacist if you are not
sure. Swallow the tablets whole with a glass of
water, do not chew. Usually you will start
treatment with 500 milligrams Glucient SR daily.
After you have been taking Glucient SR for about
2 weeks, your doctor may measure your blood
sugar and adjust the dose. The maximum daily
dose is 2000 milligrams of Glucient SR.
Normally, you should take the tablets once a day,
with your evening meal.
In some cases, your doctor may recommend that
you take the tablets twice a day. Always take the
tablets with food.
If you take more Glucient SR than you should
If you take extra tablets by mistake you need not
worry, but if you have unusual symptoms,
contact your doctor. If the overdose is large,
lactic acidosis is more likely and this is a medical
emergency requiring treatment in hospital (see
also under ‘4. Possible side effects’).
If you forget to take Glucient SR
Take it as soon as you remember with some
