1. What is Dekristol and what is it used for

Dekristol contains vitamin D (also called cholecalciferol) used to regulate the absorption and metabolism of calcium and bone mineralization. Dekristol is used:

  • for initial treatment of vitamin D deficiency in adults.

2. Important information before taking Dekristol

When not to take Dekristol:

  • if you are allergic to cholecalciferol, peanuts, soy, or any of the other ingredients of this medicine (listed in section 6);
  • if you have hypercalcemia (high calcium levels in the blood);
  • if you have hypercalciuria (high calcium levels in the urine);
  • if you have been diagnosed with hypervitaminosis D (high levels of vitamin D in the blood);
  • if you have pseudohypoparathyroidism (a disorder of parathyroid hormone balance);
  • if you have kidney stones, kidney calcification, or severe kidney dysfunction;
  • if you are taking other medicines containing vitamin D (e.g., multivitamin products).

Warnings and precautions

Before starting treatment with Dekristol, discuss it with your doctor or pharmacist:

  • if you have a tendency to form kidney stones containing calcium;
  • if you have kidney problems and they do not properly remove calcium and phosphates. Your doctor should monitor the effect of treatment on calcium and phosphate metabolism;

1/6

  • if you are taking diuretics (thiazide derivatives) or are immobilized, as there is a risk of hypercalcemia (high calcium levels in the blood) and hypercalciuria (high calcium levels in the urine);
  • if you have sarcoidosis (a disease that affects connective tissue in the lungs, skin, and joints), as there is a risk of increased conversion of vitamin D to its active form. In such cases, your doctor should monitor calcium levels in the blood and urine.

If you are taking Dekristol in a dose exceeding 1000 IU (International Units) of vitamin D per day, your doctor should monitor calcium levels in the blood and urine and check kidney function. Monitoring is especially important in elderly patients and those taking digitalis glycosides (heart stimulants) or diuretics (urine-stimulating drugs) at the same time. If calcium levels in the blood (hypercalcemia) or urine (hypercalciuria) increase, treatment should be discontinued. If signs of kidney dysfunction appear, the dose should be reduced or treatment discontinued.

Infants, young children, and adolescents

Dekristol should not be used in infants and children under 12 years of age due to possible difficulties with swallowing the capsule and the risk of choking. Instead, it is recommended to use drops or soluble tablets. Due to the lack of data on dosing, use in adolescents from 12 to 18 years of age is not recommended.

Dekristol and other medicines

Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take.

  • phenytoin (a medicine used to treat epilepsy) or barbiturates (medicines used to treat epilepsy, sleep disorders, and for anesthesia);
  • glucocorticoids (medicines used to treat certain allergic diseases),
  • rifampicin and isoniazid (medicines used to treat tuberculosis);
  • cholestyramine (a medicine used to lower elevated cholesterol levels), laxatives containing liquid paraffin;
  • orlistat (a medicine used to treat obesity);
  • actinomycin (a medicine used to treat cancer);
  • imidazole derivatives (antifungal medicines).

The effect of Dekristol or side effects may be increased by taking:

  • vitamin D metabolites or analogs (e.g., calcitriol): Avoid concomitant use with Dekristol
  • diuretics (e.g., thiazide diuretics): Reduced excretion of calcium by the kidneys may cause an increase in calcium levels in the blood (hypercalcemia). Therefore, during long-term treatment, calcium levels in the blood and urine should be systematically checked.

Dekristol taken at the same time increases the risk of side effects:

  • digitalis glycosides (medicines used to stimulate heart function): The risk of cardiac arrhythmias may increase due to increased calcium levels in the blood during vitamin D treatment. In such cases, the attending physician should perform ECG examinations, monitor calcium levels in the blood and urine, and the level of the medicine in the blood.
  • antacids or other products containing magnesium: During treatment with Dekristol, products containing magnesium should not be taken, as there is a risk of high magnesium levels in the blood.

2/6

Dekristol with food and drink

Dekristol is best taken with food and drink.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, ask your doctor for advice before taking this medicine.

During pregnancy and breastfeeding, it is not recommended to use high-dose products; products with lower doses should be used.

During pregnancy and breastfeeding, adequate intake of vitamin D is necessary. The recommended daily intake of vitamin D during pregnancy and lactation, according to national guidelines, is about 600 IU.

Pregnancy

Avoid overdosing on vitamin D during pregnancy, as prolonged hypercalcemia can lead to physical and mental impairment, supravalvular aortic stenosis (a heart defect developing before birth), and retinopathy (a disease of the retina) in the child.

Daily doses during pregnancy should not exceed 4000 IU of vitamin D. Animal studies have shown the toxic effects of high doses of vitamin D on reproduction.

Breastfeeding

Do not take high doses of vitamin D during breastfeeding. Vitamin D and its metabolites pass into breast milk. If treatment with Dekristol is clinically indicated during breastfeeding, this should be taken into account when giving the child an additional dose of vitamin D.

Driving and using machines

Dekristol has no or negligible influence on the ability to drive and use machines.

Dekristol contains arachis oil.

The duration of treatment is usually limited to the first month of treatment, depending on the doctor's decision.
