Introduction About D 500 CAL TABLET
D 500 CAL TABLET contains Calcium carbonate and Vitamin D3 (cholecalciferol) which belongs to the group of medicines called Calcium supplements and Vitamin derivatives respectively. It is used to manage calcium deficiency (low levels of calcium in blood).
Low levels of calcium are associated with poor dietary intake of calcium, mainly seen during pregnancy and lactation. D 500 CAL TABLET is also used for the management of osteoporosis (bones become brittle and fragile), osteomalacia (softening of bones), rickets (abnormal calcification, softening and distortion of the bones typically resulting in bowlegs) and hypoparathyroidism (low levels of parathyroid hormones).
Patients undergoing management with D 500 CAL TABLET will be asked to monitor their plasma levels of calcium frequently to avoid hypercalcemia (increased calcium levels).
D 500 CAL TABLET can be used during pregnancy and breast-feeding only if advised by the doctor. However, consult your doctor before taking to understand required dosages that helps to manage hypercalcemia and reduce the harm of the baby.
D 500 CAL TABLET is not recommended for use in patients with hypervitaminosis D (increased levels of vitamin D in blood), kidney stones, diseases that increases calcium levels in blood and urine (Ex. hyperparathyroidism).
D 500 CAL TABLET should be taken with caution in patients with sarcoidosis (growth of tiny collection of inflammatory cells or granulomas in any part of the body), immobilised patients with osteoporosis (brittle bones), malignancies (abnormal growth of cells) and impaired renal function.
The most common side effects of taking D 500 CAL TABLET includes nausea, vomiting, constipation, excess gas, dry mouth, loss of hunger and acid refluxes. Consult your doctor if any of the side effects worsen.
Uses Of D 500 CAL TABLET
Used to manage:
- low levels of calcium in blood (mainly occurs during pregnancy and lactation period)
- osteoporosis (brittle bones)
- osteomalacia (softening of bones)
- rickets (abnormal calcification, softening and distortion of the bones typically resulting in bowlegs)
- hypoparathyroidism
- malnutrition due to poor nutritional intake
How D 500 CAL TABLET Works
D 500 CAL TABLET contains vitamin D3 and calcium carbonate. Vitamin D3 helps to enhance the intestinal absorption of calcium. Calcium carbonate acts as a calcium supplement. Combination of calcium carbonate and Vitamin D3 helps to counteract the increase in parathyroid hormone that is caused by calcium deficiency and which causes increased bone resorption (destruction of bone tissue that promotes bone loss). This helps to strengthen the bones, teeth and muscle functions.
