1. What is Normalac and what is it used for

The medicine contains the active substance lactulose, which is a synthetic disaccharide that is not broken down in the small intestine. Lactulose reaches the large intestine unchanged, where it is broken down by bacteria into carbon dioxide and low-molecular-weight organic acids (such as lactic acid, acetic acid, and formic acid).
These acids cause:

  • a decrease in pH in the large intestine, thereby increasing acidity, which has a significant impact on many metabolic processes and the balance of the intestinal flora;
  • a natural regulation of bowel movements, by increasing the water content in the stool.

Indications for use:

  • hepatic encephalopathy (neuropsychiatric disorders caused by liver damage, especially liver cirrhosis);
  • constipation (regulation of bowel movements).

2. Important information before taking Normalac

When not to take Normalac

  • if the patient is allergic to the active substance or any of the other ingredients of this medicine (listed in section 6);
  • if the patient has galactosemia (a congenital disorder of sugar metabolism - inability to convert galactose to glucose);
  • if the patient has intestinal obstruction (severe crampy abdominal pain, vomiting, bloating, the patient does not pass gas or stool);
  • if the patient has acute inflammatory bowel diseases, including ulcerative colitis and proctitis, Crohn's disease (characterized by chronic diarrhea).

Warnings and precautions

  • Normalac should not be taken if abdominal pain, nausea, and vomiting occur.
  • Before taking Normalac, the patient should tell their doctor: if they have persistent constipation,
  • if they have diabetes (see section: The medicine contains lactose monohydrate, galactose, fructose).

In case of long-term use of Normalac, the patient should contact their doctor, who may prescribe a blood test (electrolyte level determination).
Children
In special cases, the doctor may prescribe Normalac for use in children, infants, or newborns. Normalac can be given to infants and young children only on the advice of a doctor, as it may disrupt the natural bowel movement reflex.
In such cases, treatment will be closely monitored by the doctor.

Normalac and other medicines

The patient should tell their pharmacist or doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
Before taking Normalac, the patient should inform their doctor if they are taking:

  • neomycin (an antibiotic used to treat infections);
  • digoxin (a medicine used to treat heart failure and heart rhythm disorders), as Normalac may increase its toxic effects, especially if taken in large doses;
