Pregnancy and Lactation
There are limited data on the use of colecalciferol in pregnant women. Animal studies have shown its reproductive toxicity. For pregnant and lactating women, the recommended daily dosage is 400 IU; however, patients with Vitamin D deficiency may require a higher dosage (up to 2000 IU/day). During pregnancy, patients should follow the recommendations of their physician, as the requirements for use depend on the severity of the disease and clinical response.
Vitamin D and its metabolites are excreted into maternal milk; however, no cases of overdose caused by Vitamin D in maternal milk have been reported in infants. When prescribing vitamin D to a child, the physician should consider the additional dosage of Vitamin D that the child's nursing mother is taking. Less Vitamin D supplementation is required during pregnancy and lactation, therefore, Devit tablets with a high dosage of 50,000 IU of colecalciferol should not be used in pregnancy and during lactation.
