Daonil – Glibenclamide uses, dose and side effects


3.5 mg Tablets 

1. What Daonil is and what it is used for

Daniel seems to lower blood sugar, partly by increasing insulin production and possibly partly by making the body’s own insulin et more efficiently.

Daonil is used for type 2 diabetes mellitus (adult diabetes), like diet, exercise, and weight reduction alone do not have a sufficient effect.

2. What you need to know before using Daonil

Do not use Daonil

  • if you are allergic (hypersensitive) to glibenclamide or any of the other ingredients of Daonil.
  • if you have type 1 diabetes mellitus (insulin-dependent diabetes ).
  • in diabetic coma and case of the too high content of acidic substances in the body ( ketoacidosis ).
  • in case of malnutrition.
  • in severe renal or hepatic impairment.
  • in acute conditions that complicate diabetes, such as infection or cold sores.
  • when co-administered with medicines containing bosentan (used to treat high blood pressure in the blood vessels of the lungs).

Take special care with Daonil:

Blood sugar should be checked regularly.

The risk of low blood sugar (hypoglycemia) is increased during the first weeks of treatment.

Elderly patients may be more sensitive to low blood sugar, so your doctor will adjust the dose to as low a dose as possible.

With impaired renal or hepatic function and after prolonged fasting, the blood sugar lowering effect may become too strong.

Hypoglycemia (hypoglycemia)

Hypoglycemia (hypoglycemia), a so-called “feeling”, can occur with the concomitant use of other drugs, overdose, irregular meals, decreased food or fluid intake, stress, and increased physical activity.

Mild symptoms of low blood sugar can range from hunger, lethargy, drowsiness, visual disturbances, irritability, emotional disturbances, confusion, sweating, anxiety, tremors, coordination problems, pallor, and headaches. In most cases, the symptoms disappear fairly quickly after consuming sugar. You should therefore always carry some form of sugar with you, such as grape sugar, chocolate, or the like. Note that sweeteners do not affect. If sugar intake does not help or if symptoms return, contact your doctor or hospital. More serious symptoms of low blood sugar can be seizures and if the blood sugar does not rise, unconsciousness can occur. Doctors should be contacted immediately in case of more severe symptoms.

In case of severe overdose, there is a risk of affecting the brain, heart, blood, liver, and respiration.

Elevated blood sugar (hyperglycemia)

Signs of high blood sugar (hyperglycemia) may include thirst, frequent urination, dry mouth, and dry skin. In such cases, a doctor should be consulted. In connection with accidents, operations, and febrile conditions, it may be necessary to switch to insulin treatment.
