Medical information

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking glibenclamide it is important that your doctor knows:

If you are pregnant, trying for a baby or breastfeeding.
If you have any problems with the way your liver works, or with the way your kidneys work.
If you have been told you have porphyria or glucose 6-phosphate dehydrogenase (G6PD) deficiency. These are rare inherited disorders.
If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

Glibenclamide works by increasing the amount of insulin that your pancreas produces. This helps to reduce the amount of sugar in your blood.
