What is cholecalciferol?
Cholecalciferol is a vitamin D3. Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.
Cholecalciferol is used to treat or prevent many conditions caused by a lack of vitamin D, especially conditions of the skin or bones.
Cholecalciferol may also be used for other purposes not listed in this medication guide.
Do not use this medication if you have ever had an allergic reaction to vitamin D, or if you have:
- high levels of calcium in your blood (hypercalcemia);
- high levels of vitamin D in your body (hypervitaminosis D); or
- any condition that makes it hard for your body to absorb nutrients from food (malabsorption).
Before taking cholecalciferol, tell your doctor if you are allergic to any drugs, or if you have:
- heart disease;
- kidney disease; or
- an electrolyte imbalance.
If you have any of these conditions, you may need a dose adjustment or special tests to safely take this medication.
Your cholecalciferol dose needs may change if you are pregnant or breast-feeding. Tell your doctor if you are pregnant or plan to become pregnant during treatment, or if you are breast-feeding a baby.
Do not take other vitamin or mineral supplements unless your doctor has told you to.
Avoid using calcium supplements or antacids without your doctor’s advice. Use only the specific type of supplement or antacid your doctor recommends.
