About Calcium and Calcitriol Tablet
This medicine contains calcium and calcitriol. Calcium and calcitriol tablet is used to prevent and treat calcium and vitamin D deficiency, osteoporosis, osteomalacia, hypocalcemia, and other conditions requiring calcium supplementation.
Calcium is an essential mineral that helps build and maintain strong bones and teeth, supports muscle function, nerve transmission, and normal heart function. Calcitriol is an active form of vitamin D3 that increases the absorption of calcium from the intestine and helps maintain healthy calcium levels in the body.
Common side effects include constipation, nausea, stomach upset, bloating, and mild abdominal discomfort. Rarely, excessive use may lead to high calcium levels (hypercalcemia), which may cause excessive thirst, frequent urination, confusion, or kidney stones. Use this medicine only as prescribed by your doctor.

How Calcium and Calcitriol Tablet works
This medicine contains calcium carbonate and calcitriol. Calcium carbonate provides calcium required for building and maintaining strong bones and teeth. Calcitriol, the active form of vitamin D, increases calcium absorption from the intestine, helps maintain normal calcium levels in the blood, and supports bone mineralization. Together, these ingredients strengthen bones, improve calcium utilization, and promote overall skeletal health.
