About BrandName
BrandName tablet is an oral supplement, containing Calcium Carbonate 500 mg + Alfacalcidol 0.25 mg. BrandName is used to improve calcium levels and support bone health. It is commonly prescribed in calcium deficiency, vitamin D deficiency, osteoporosis, fracture recovery, muscle cramps, and in people with increased calcium needs such as elderly individuals and postmenopausal women.
Calcium carbonate provides a high amount of elemental calcium needed to build and maintain strong bones and teeth. Alfacalcidol is a vitamin D analogue that gets converted into active vitamin D, helping increase calcium absorption from the intestine and maintain proper calcium levels in the blood.
BrandName common side effects include constipation, diarrhea, stomach upset, abdominal pain, nausea, vomiting, and bloating. Taking it after food can help reduce stomach discomfort. Avoid taking more than prescribed, as excess calcium or vitamin D can lead to high calcium levels in the blood, which may cause weakness, confusion, or kidney problems.
