Why is this medication prescribed?

Calcitriol is a medication primarily prescribed to treat conditions related to low levels of calcium or problems with parathyroid gland function. Here’s why and how it is used:

• Hypocalcemia: Calcitriol is used to treat low levels of calcium in the blood, which can occur due to various reasons including kidney disease or vitamin D deficiency.
• Hypoparathyroidism: It is also prescribed for individuals with hypoparathyroidism, a condition where the parathyroid glands do not produce enough parathyroid hormone (PTH). PTH helps regulate calcium and phosphorus levels in the body.

How should this medicine be used?

How Calcitriol should be used:

• Dosage: The dosage of Calcitriol varies depending on the condition being treated and the patient’s specific needs. It is typically taken orally (by mouth) in the form of capsules or liquid.

• Timing: Usually, Calcitriol is taken once daily, although your doctor may adjust the frequency based on your condition.
• Monitoring: Regular blood tests may be necessary to monitor your calcium levels while taking Calcitriol, especially at the beginning of treatment or if your dosage changes.
• Food Interactions: It’s important to take Calcitriol with food to enhance absorption and reduce the risk of stomach upset.
