You should not take ergocalciferol if you have had an allergic reaction to vitamin D, or if you have high levels of calcium or vitamin D in your body, or any condition that makes it hard for your body to absorb nutrients from food (malabsorption).

Before taking this medicine
You should not take ergocalciferol if you have had an allergic reaction to vitamin D, or if you have:
high levels of vitamin D in your body (hypervitaminosis D);
high levels of calcium in your blood (hypercalcemia); or
any condition that makes it hard for your body to absorb nutrients from food (malabsorption).
Tell your doctor if you have ever had:
heart disease;

Certain forms of ergocalciferol may contain ingredients you should know about, such as peanut or soybean oil, sugar, aspartame (phenylalanine), or certain food dyes. Ask a doctor before using ergocalciferol if you have allergies, diabetes, or phenylketonuria (PKU).
Too much vitamin D could harm an unborn baby, and your dose needs may be different during pregnancy. Tell your doctor if you are pregnant or if you become pregnant while taking ergocalciferol.
Ergocalciferol can pass into breast milk and may cause side effects in the nursing baby. Tell your doctor if you are breast-feeding.
Do not give ergocalciferol to a child without medical advice. Your child's dose will depend on age, weight, diet, and other factors.
