Calcitriol
Summary
Calcitriol is used to treat hypoparathyroidism, which is when the parathyroid glands don't produce enough hormone, and chronic kidney disease. It helps manage calcium and phosphate levels in the body.
Calcitriol increases calcium absorption in the intestines, which are the digestive organs, and promotes bone health. It helps regulate calcium and phosphate levels, which are essential minerals, in the body.
Calcitriol is usually taken as a capsule once daily, with or without food. The starting dose for adults is typically 0.25 micrograms per day, and the maximum dose is usually 2 micrograms per day.
Common side effects of Calcitriol include high calcium levels, which can cause nausea, vomiting, and weakness. These effects vary from person to person.
Calcitriol can cause hypercalcemia, which is high calcium levels in the blood, leading to nausea and confusion. It's contraindicated in hypercalcemia and vitamin D toxicity. Regular blood tests are needed to monitor calcium levels.
