Patient Education

Calcium Carbonate


Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. Calcium is needed by the body for healthy bones, muscles, nervous system, and heart. Calcium carbonate also is used as an antacid to relieve heartburn, acid indigestion, and upset stomach. It is available with or without a prescription. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Cholecalciferol (Vitamin D3)


Cholecalciferol (vitamin D3) is used as a dietary supplement when the amount of vitamin D in the diet is not enough. People most at risk for vitamin D deficiency are older adults, breastfed infants, people with dark skin, obese people, and those with limited sun exposure, or gastrointestinal disease (GI; affecting the stomach or intestines) such as Crohn's disease or celiac disease. Cholecalciferol (vitamin D3) is also used along with calcium to prevent and treat bone diseases such as rickets (softening and weakening of bones in children caused by lack of vitamin D), osteomalacia (softening and weakening of bones in adults caused by lack of vitamin D), and osteoporosis (a condition in which the bones become thin and weak and break easily). Cholecalciferol (vitamin D3) is in a class of medications called vitamin D analogs. Cholecalciferol is needed by the body for healthy bones, muscles, nerves, and to support the immune system. It works by helping the body to use more of the calcium found in foods or supplements.
