6. Contents of the pack and other information
Yaltormin 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. Yaltormin SR is
used for the treatment of Type 2 (non-insulin dependent) 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. Yaltormin SR makes the body more
sensitive to insulin and helps return to normal the way your body uses glucose.
Yaltormin SR is associated with either a stable body weight or modest weight loss.
Yaltormin 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.
Do not take Yaltormin SR if:
• you are allergic to metformin or to any of the other ingredients which are listed later on in the
leaflet (see under ‘6. Further information’). An allergic reaction may cause a rash, itching or
shortness of breath.
• 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 or dehydration.
• 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 your 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 ‘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
If you need to have an X-ray examination involving the injection of a dye, tell the doctor that you take
Yaltormin 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 Yaltormin 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 Yaltormin SR:
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
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, beclometasone.
• 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 anaesthetics.
You should avoid using alcohol-containing medicines as this will increase the risk of lactic acidosis
(see under ‘4. Possible side effects’).
Yaltormin SR with food, drink and alcohol:
You should take Yaltormin SR with or immediately after food.
You should avoid drinking alcohol as this will increase the risk of lactic acidosis (see under ‘4. Possible
side effects’).
Pregnancy and breast-feeding
Do not take Yaltormin SR if you are pregnant or breast feeding. Ask your doctor or pharmacist for
advice before taking any medicine.
Driving and using machines
Yaltormin 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 Yaltormin SR taken with other antidiabetic medicines can cause
hypos, so in this case you should take extra care when driving or operating machinery.
Your doctor may prescribe Yaltormin 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 has told you. 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 Yaltormin SR daily. After you have been taking
Yaltormin SR for about 2 weeks, your doctor may measure your blood sugar and adjust the dose. The
maximum daily dose is 2000 milligrams of Yaltormin 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 Yaltormin SR than you should
If you take extra tablets by mistake you need not worry, but if you have unusual symptoms, contact
your doctor. These symptoms may include weakness, confusion, fast breathing and new onset of
nausea, vomiting or stomach pain. 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 Yaltormin SR
Take it as soon as you remember with some food. Do not take a double dose to make up for a
forgotten dose.
Like all medicines, this medicine can cause side effects, although not everybody gets them. If you
notice any of the following, stop taking Yaltormin SR and see your doctor immediately:
• unexpected weight loss
• very severe nausea or vomiting
• very fast breathing which you cannot stop
• stomach pains or feeling cold
These can be signs of serious problems with your diabetes and may mean you have a very rare side
effect called “lactic acidosis” (too much acid in the blood). If this happens, see a doctor as you will
need treatment straight away.
• Abnormal liver function tests and hepatitis (inflammation of the liver) which may result in jaundice.
If you develop yellowing of the eyes and/or skin contact your doctor immediately.
Other possible side effects are listed by frequency as follows:
Very common (affects more than 1 person in 10):
• Diarrhoea, nausea, vomiting, stomach ache or loss of appetite. If you get these, do not stop taking
the tablets as these symptoms will normally go away in about 2 weeks. It helps if you take the
tablets with or immediately after a meal.
Common (affects less than 1 person in 10, but more than 1 person in 100):
• Taste disturbance
Very rare (affects less than 1 person in 10,000):
• Decreased vitamin B12 levels
