What Is Calcium Carbonate and How Does It Work?

Calcium Carbonate is a medication used to prevent or treat low blood calcium levels in people who do not get enough calcium from their diets. It may be used to treat conditions caused by low calcium levels such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany). It may also be used in certain patients to make sure that they are getting enough calcium (women who are pregnant, nursing or postmenopausal, people taking certain medications such as phenytoin, phenobarbital, or prednisone).

Calcium plays a very important role in the body. It is necessary for normal functioning of nerves, cells, muscle, and bone. If there is not enough calcium in the blood, then the body will take calcium from bones, thereby weakening bones. Having the right amount of calcium is important for building and keeping strong bones.

Calcium Carbonate is available under the following different brand names: Tums, Tums Chewy Delights, Tums Extra, Tums Freshers, Tums Kids, Tums Regular, Tums Smoothies, and Tums Ultra or Children's Pepto.
