very rare condition called “lactic acidosis” which can be
dangerous and needs urgent hospital attention.

Pregnancy and breast-feeding
Do not take Sukkarto SR if you are pregnant or breastfeeding. Tell your doctor immediately if you think you are
pregnant or are breast-feeding.

The following side effects have also been reported:

Driving and using machines:
Sukkarto 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 Sukkarto SR taken with
other antidiabetic medicines can cause hypos, so in this case
you should take extra care when driving or operating

Very common (affecting more than one person in 10):

Stomach pains or stomach upsets such as nausea,

vomiting, diarrhoea, loss of appetite.
These effects usually get better spontaneously and you
should continue to take the tablets. If these do not get better
after a few days, tell your doctor. It helps if you take your
tablets with or immediately after a meal.

Common (affecting less than one person in 10 but more than
one person in 100):
Taste disturbance.
Very rare (affecting less than one in 10,000):

The usual dose is:
Adults: The usual starting dose is one 500 mg tablet daily with
your evening meals. After two weeks your doctor may

been carried out on your kidney function.
Children and adolescents below 18 years: The use of the

Your doctor will test your blood glucose and your kidney

requiring treatment in hospital (see also under “4. Possible
side effects”).

Take the missed dose as soon as you remember, unless it's
nearly time for the next one. Do not take a double dose to
