Introduction to Calcitriol

Calcitriol is a medication used to treat conditions that arise from low levels of calcium or vitamin D in the body. It is particularly beneficial for individuals with chronic kidney disease, hypoparathyroidism, and bone softening conditions like rickets or osteomalacia due to vitamin D deficiency.

Composition of Calcitriol

Calcitriol is the synthetic active form of vitamin D3. It plays a crucial role in regulating calcium absorption and utilization in the body, enhancing calcium absorption from the intestines, promoting phosphate absorption necessary for bone formation, and regulating bone resorption.

Uses of Calcitriol

• Management of chronic kidney disease
• Treatment of hypoparathyroidism
• Prevention and treatment of bone softening conditions like rickets or osteomalacia

Side effects of Calcitriol

Common side effects:

• Weakness
• Headache
• Nausea
• Vomiting

Serious side effects:

• High levels of calcium in the blood (hypercalcemia)
• High levels of phosphate in the blood (hyperphosphatemia)

Precautions of Calcitriol

Calcitriol should be avoided by individuals with high calcium levels, vitamin D toxicity, severe kidney disease, a history of kidney stones, and high phosphate levels. It can cause dangerously high calcium levels in your blood, which requires immediate medical attention.

How to Take Calcitriol

• The dosage depends on your age and the condition being treated.
• Adults and older children usually take between 0.5 and 2 mcg a day.
• It is typically taken once daily, with or without food.
