Calcichew tablets contain the active ingredient calcium carbonate, which is a calcium salt used mainly to supplement calcium in the diet.
Calcium is an essential mineral needed for many purposes in the body, including the formation of strong bones. Calcium requirements are raised in the years following the menopause, and when dietary intake of calcium is low. Calcium supplements have been shown to help prevent bone loss.
Calcium is found in milk and dairy products, as well as spinach, nuts and sardines. Usually, calcium requirements are met from the diet. However, there are times when the amount of calcium required is increased, such as during growth, pregnancy, when breastfeeding or with advancing age. When there is insufficient calcium in the diet to meet the body's needs, supplements are needed, otherwise calcium deficiency can occur.
Calcium supplements are useful in osteoporosis; a calcium intake that is twice the recommended daily allowance (RDA) slows the rate of bone loss and reduces the risk of fractures.
Calcium carbonate is also used in people with kidney failure to bind to phosphate consumed in the diet. This is because in kidney failure the kidneys are less able to remove phosphate from the blood and it builds up in the body, often causing itching of the skin. High levels of phosphate also lead to a drop in the amount of calcium in the body, and as a result the body starts removing calcium from the bones. This can cause renal bone disease. Calcium carbonate is used as a phosphate binder in kidney failure to reduce the amount of phosphate absorbed from the gut. It therefore helps prevent these problems.

To avoid the calcium stopping these medicines from being adequately absorbed, your dose of Calcichew should be separated from these medicines by at least four hours. Ask your pharmacist for further advice.
Thiazide diuretics, such as bendroflumethiazide, reduce the amount of calcium excreted in the urine, and this can increase the amount of calcium in the blood. If you are taking a thiazide diuretic in combination with this medicine you should have regular blood tests to monitor the level of calcium in your blood.
People taking digoxin or other cardiac glycosides may have an increased risk of abnormal heart rhythms if they experience abnormally high blood calcium levels while taking this medicine.
