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.    

Calcium and Calcitriol Tablet is used to treat and relieve symptoms of the following conditions: 

1. Calcium deficiency (weak bones, muscle cramps, low calcium levels) 
2. Osteoporosis (weak and brittle bones) 
3. Bone weakness and fracture healing support 
4. Vitamin D-related calcium absorption problems 
5. Support overall bone and teeth health

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.

Avoid taking Calcium and Calcitriol Tablet with the following medicines, as it may increase or decrease the desired effect, or in worse cases, it could be fatal: 

Avoid taking this medicine together with tea, coffee, high-fiber foods, spinach, bran, and foods rich in phytates or oxalates, as they may reduce calcium absorption. It is best taken after meals with water for better absorption and to reduce stomach upset.
