What is cholecalciferol?
Cholecalciferol is vitamin D3 . Vitamin D helps your body absorb calcium.
Cholecalciferol is used as a dietary supplement in people who do not get enough vitamin D in their diets to maintain adequate health.
Cholecalciferol may also be used for purposes not listed in this guide.
You should not take cholecalciferol 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 use cholecalciferol 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;
- kidney disease; or
- an electrolyte imbalance.
Certain forms of cholecalciferol 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 cholecalciferol if you have allergies , diabetes, or phenylketonuria (PKU).
Too much vitamin D could harm an unborn baby or a nursing baby. Ask a doctor before using cholecalciferol if you are pregnant or breastfeeding. Your dose needs may be different during pregnancy or while you are nursing.
Do not give cholecalciferol to a child without medical advice. Your child’s dose will depend on age, weight, diet, and other factors.
How should I take cholecalciferol?
Follow all directions on your prescription label and read all the guides or instruction sheets. Use only the recommended dose of cholecalciferol.
It may be best to take cholecalciferol after a meal, but you may take it with or without food.
Measure liquid cholecalciferol carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
The chewable tablet must be chewed before you swallow it.
To take a disintegrating (Quick-Melt) tablet, place it on your tongue and do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing. If desired, you may drink liquid to help swallow the dissolved tablet.
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.
While using cholecalciferol, you will need frequent blood tests. You may also need x-rays.
Your doctor will determine how long to treat you with cholecalciferol.
Cholecalciferol may be only part of a complete program of treatment that also includes dietary changes and taking calcium and vitamin supplements. Follow your doctor’s instructions very closely.
Learn about the foods you should eat to make sure you get enough calcium and vitamin D in your diet. Your cholecalciferol dose may need to be adjusted as you make changes to your diet.
Store at room temperature away from moisture, light, and heat.
