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 purposes not listed in this medication guide.
What is the most important information I should know about cholecalciferol?
You should not use cholecalciferol if you have high levels of calcium or vitamin D in your blood, or if you have any condition that makes it hard for your body to absorb nutrients from food (malabsorption).
What should I discuss with my healthcare provider before taking cholecalciferol?
You should not use cholecalciferol 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).
To make sure you can safely take cholecalciferol, tell your doctor if you have any of these other conditions:
kidney disease; or
an electrolyte imbalance.
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.
How should I take cholecalciferol?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
The chewable tablet must be chewed before you swallow it.
The cholecalciferol wafer is usually taken only once per week or once per month. Follow your doctor's dosing instructions very carefully. The wafer must be chewed before you swallow it.
Cholecalciferol is only part of a complete program of treatment that may also include a special diet. It is very important to follow the diet plan created for you by your doctor or nutrition counselor. You should become very familiar with the list of foods you must eat or avoid to help control your condition.
Store at room temperature away from moisture, light, and heat.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of vitamin D can cause serious or life-threatening side effects.
What should I avoid while taking cholecalciferol?
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.
