International generic name
Drug form and composition
Solution , oral drops. 1 ml Solution contains 30 000 IU Retinol palmitate (Vitamin
A), and 40 000 IU Ergocalciferol (Vitamin D2).
The preparation is indicated in the combined treatment of the hypo- and avitaminosis
A and D; rachitis; xerophtalmia; hypoparathyroidism; retarded bone fracture healing;
osteomalacia; visual disorders.
Dosage and administration
The main goal of the rachitis prevention is to supply individual daily requirements
of Vitamin D. Usually the daily dose 500 - 1 000 IU is sufficient to meet the daily
requirements of the children organism. In prematurely born children and children
with low body weight prevention should be started 8 days after the birth, and the
daily requirements are higher: 2 000 IU, and 1 500 IU in children with birth body
weight lower than 1 500 g, and 1 500 - 2 000 g respectively. The treatment of the
rachitis should be complex and individually adjusted. The daily dose and duration
of the treatment depend on the form and the severity of the disease. Following doses
of Vitamin D are recommended: initial mild rachitis - 2 000 - 4 000 IU daily; moderate
rachitis - 4 000 - 6 000 IU; severe rachitis - 6 000-10 000 IU. In patients with
hypothyroid conditions a high dose Vitamin D may provoke phosphaturia with concomitant
elevation of the calcium serum level, which should be kept in mind when the daily
dose is specified - 250 000 IU. In relevance with the former, recommended daily
doses Deavit are as follows: in adults is 10-15 drops, in infants - 3-6 drops, and
in children 5-10 drops.
The preparation is contraindicated in hypersensitivity to any of its components,
hypervitaminosis D and A, severe acute and chronic liver and renal diseases, generalized
arteriosclerosis, heart failure, and severe calcium and phosphate dysbalance.
Special warnings and precautions
In adult patients the dose should be carefully specified, as the increased deposition
of calcium in the body stimulates the development of arteriosclerosis. The preparation
should be used with care in hypercholesterolemia, hypercalcemia, hyperphosphatemia,
and hypersensitivity to Vitamin D, ulcer disease, sarcoidosis, and pulmonary tuberculosis.
Deavit should be administered with particular care during the pregnancy and lactation,
with individual specification of the daily dose and the duration of the treatment.
Data exist that over dosage of Vitamin A and D may lead to fatal malformations -
hypersensitivity of newborn to Vitamin D effect, depression of the parathyroid function;
congenital aortic valve stenosis. In long-term administration in high dose fatigue
and somnolence may appear, which may influence the motor activity and concentration
In concomitant administration with laxative drugs, cholestyramine, and sucralfate
Vitamin A and D deficiency may appear, due to resorption disorders. Thyroxin reduces
the Vitamin A effect. Oral contraceptive agents reduce plasma levels of the Vitamin
A and exhaust Vitamin A stores. Barbiturates and hydantoin anti-convulsion medicines
reduce the Vitamin D effect, changing its metabolism by enzyme reduction. Vitamin
D antagonizes effects of calcitonin. Concomitant administration with calcium-containing
preparations and thiazide diuretics enhance the risk of hypercalcemia. In oral administration
Vitamin A reduce effects of corticosteroids, whereas in dermal application it enhances
their epithelia-stimulating effect.
The preparation is very well tolerated. Sometimes following symptoms may be seen:
fatigue, somnolence, anorexia, alopecia, menstrual disorders, and allergy reactions.
In very rare cases skin dystrophy, cortical hyperostosis, preliminary closure of
the long bone epiphyses, and hyperthermia were seen.
Vitamin A (retinol) is known as an anti-xerophtalic vitamin. It possesses an
epithelia-stimulating effect - contributes to normal constructing and normal development
of the epithelial cells of the skin and mucous membranes; improves the resistance
of the epithelial tissue to physical, chemical and bacterial harmful agents. Vitamin
A participates in synthesis of the visual pigment rhodopsin, responsible for the
adaptation of the eye to the poor light. It stimulates synthesis of the sexual hormones
and corticosteroids. Improves resistance of the organism to a low temperature and
infectious diseases. Vitamin D (ergocalciferol) improves calcium and phosphate absorption
in the gastrointestinal tract, regulates their exchange, and facilitates their deposition
in the bones. Vitamin D improves tissue metabolism; normalizes functioning of the
gastrointestinal tract and the liver.
Vial, containing 10 ml solution.
