Symptoms hypervitaminosis D: early (due to hypercalcemia) — constipation or diarrhea, dryness of the oral mucosa, headache, thirst, pollakiuria, nycturia, polyuria, anorexia, metallic taste in the mouth, nausea, vomiting, extreme fatigue, asthenia, hypercalcemia, hypercalciuria, late — bone pain, turbidity of urine (appearance of hyaline cylinders in the urine, proteinuria, leukocyturia), increased blood pressure, itching, photosensitivity eye, conjunctival hyperemia, arrhythmia, drowsiness, myalgia, nausea, vomiting, pancreatitis, gastralgia, weight loss, rarely — changes in the psyche (up to the development of psychosis) and mood.
Symptoms chronic vitamin D intoxication (when taken for several weeks or months for adults in doses of 20-60 thousand mg). IU/day, children from 2 to 4 thousand IU / day): calcification of soft tissues, kidneys, lungs, blood vessels, arterial hypertension, renal and cardiovascular insufficiency up to a fatal outcome (these effects most often occur when hypercalcemia is associated with hyperphosphatemia), growth disorders in children (long-term administration at a dose of 1.8 thousand mg). IU/day).
Treatment: if signs of hypervitaminosis D appear, it is necessary to cancel the drug, limit the intake of calcium, and prescribe vitamins A, C, and B.
Symptoms hypervitaminosis D2: early (due to hypercalcemia) - constipation or diarrhea, dryness of the oral mucosa, headache, thirst, pollakiuria, nycturia, polyuria, anorexia, metallic taste in the mouth, nausea, vomiting, unusual fatigue, asthenia, hypercalcemia, hypercalciuria, late — bone pain, turbidity of urine, (appearance of hyaline cylinders in the urine, proteinuria, leukocyturia), increased blood pressure, itching, photosensitivity of the eyes, conjunctival hyperemia, arrhythmia, drowsiness, myalgia, nausea, vomiting, pancreatitis, gastralgia, weight loss, rarely — changes in mood and psyche (up to the development of psychosis).
Symptoms chronic vitamin D intoxication2 (when taken for several weeks or months for adults in doses of 20-60 thous. IU/day, for children — 2-4 thousand. IU / day): calcification of soft tissues, kidneys, lungs, blood vessels, arterial hypertension, renal and cardiovascular insufficiency up to a fatal outcome (these effects most often occur when joining hypercalcemia/hyperphosphatemia), growth disorders in children (long-term use at a dose of 1.8 thousand mg). IU/day).
Treatment: if signs of hypervitaminosis D appear, it is necessary to cancel the drug, limit the intake of calcium, and prescribe vitamins A, C, and B.

With caution: atherosclerosis, old age, pulmonary tuberculosis (active form), sarcoidosis or other granulomatoses, chronic heart failure, hyperphosphatemia, phosphate nephrourolithiasis, chronic renal failure, pregnancy (in women over 35 years of age), lactation, childhood.

With caution: atherosclerosis, old age (may contribute to the development of atherosclerosis), pulmonary tuberculosis (active form), sarcoidosis or other granulomatosis, chronic heart failure, pregnancy (in women over 35 years of age), lactation, childhood.
The toxic effect is weakened by vitamin A, tocopherol, ascorbic acid, pantothenic acid, thiamine, riboflavin, pyridoxine.
Thiazide diuretics, drugs containing calcium, increase the risk of hypercalcemia (require monitoring of the concentration of calcium in the blood).
In hypervitaminosis caused by Calciferol BD (Ergocalciferol)om, it is possible to increase the action of cardiac glycosides and increase the risk of arrhythmia due to the development of hypercalcemia (it is advisable to adjust the dose of cardiac glycoside). Under the influence of barbiturates (including phenobarbital), phenytoin and primidone, the need for Calciferol BD (Ergocalciferol)e can significantly increase, which is expressed in an increase in osteomalacia or the severity of rickets (due to the acceleration of the metabolism of Calciferol BD (Ergocalciferol)a to inactive metabolites due to the induction of microsomal enzymes).
Long-term therapy with the simultaneous use of antacids containing aluminum and magnesium increases their concentration in the blood and the risk of intoxication (especially in the presence of chronic renal failure).
Calcitonin derived etidronate and pamidronate acids, plicamycin, gallium nitrate and corticosteroids reduce the effect.
Colestyramine, colestipol and mineral oils reduce the absorption of fat-soluble vitamins in the gastrointestinal tract and require an increase in their dosage.
Increases the absorption of phosphorus-containing drugs and the risk of hyperphosphatemia.
Concomitant use with other vitamin D analogues increases the risk of hypervitaminosis.
The toxic effect is weakened by vitamin A, vitamin E, ascorbic acid, pantothenic acid, thiamine, riboflavin, pyridoxine.
Thiazide diuretics, drugs containing calcium, increase the risk of hypercalcemia (require monitoring of the concentration of calcium in the blood).
With hypervitaminosis caused by the use of ergocalciferol, it is possible to increase the action of cardiac glycosides and increase the risk of arrhythmia due to the development of hypercalcemia (it is advisable to adjust the dose of cardiac glycosides).
Under the influence of barbiturates (including phenobarbital), phenytoin, primidone, the need for ergocalciferol can significantly increase, which is expressed in an increase in osteomalacia or the severity of rickets (due to the acceleration of the metabolism of ergocalciferol into inactive metabolites due to the induction of microsomal enzymes).
Long-term therapy with the simultaneous use of antacids containing aluminum and magnesium ions increases their concentration in the blood and the risk of intoxication (especially in the presence of chronic renal failure).
Calcitonin derived etidronate and pamidronate acids, plicamycin, gallium nitrate and corticosteroids reduce the effect.
Colestyramine, colestipol and mineral oils reduce the absorption of fat-soluble vitamins in the gastrointestinal tract and require an increase in their dosage.
Increases the absorption of phosphorus-containing drugs and the risk of hyperphosphatemia.
Concomitant use with other vitamin D analogues2 (especially calcifediol) increases the risk of hypervitaminosis.

Vitamin D2 regulates the exchange of calcium and phosphorus in the body, accelerates the absorption of calcium in the intestine, improves the reabsorption of calcium and phosphorus in the kidneys, maintains the necessary level of these elements in the blood, promotes the formation of the bone skeleton in children, as well as the preservation of bone structure. Vitamin D2 it is also necessary for the manifestation of the physiological action of a number of hormones (TSH and thyrocalcitonin). Vitamin D deficiency2 in young children, it causes rickets.
