What is Decara?
Decara is vitamin D3. Vitamin D helps your body absorb calcium.
Decara is used as a dietary supplement in people who do not get enough vitamin D in their diets to maintain adequate health.
Decara may also be used for purposes not listed in this medication guide.
You should not take Decara 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 Decara 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).
To make sure Decara is safe for you, tell your doctor if you have ever had:
kidney disease; or
an electrolyte imbalance.
Certain forms of Decara 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 this medicine 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 this medicine if you are pregnant or breast-feeding. Your dose needs may be different during pregnancy or while you are nursing.
Do not give Decara to a child without medical advice. Your child's dose will depend on age, weight, diet, and other factors.
