How does calcitriol work?

calcitriol is dosed as follows:
- Adults: The typical starting dose is 0.25 mcg by mouth daily. Your provider will check your blood calcium levels throughout therapy. They might raise your dose if your levels remain low
- Children: Your child’s dose will depend on their age, weight, and the reason they’re taking calcitriol (calcitriol).

calcitriol is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects.

Effects of other drugs, drug classes and over-the-counter products on calcitriol
The following medications may interact with calcitriol:
- Cholestyramine has been reported to reduce intestinal absorption of fatsoluble vitamins; as such it may impair intestinal absorption of calcitriol/
- The coadministration of phenytoin or phenobarbital will not affect plasma concentrations of calcitriol, but may reduce endogenous plasma levels of 25(OH)D3 by inhibiting 25-hydroxylase in liver. Since endogenous synthesis of calcitriol will be inhibited, higher doses of calcitriol may benecessary if these drugs are administered simultaneously
- Thiazides are known to induce hypercalcemia by the reduction of calcium excretion in urine
- Some reports have shown that the concomitant administration of thiazides with calcitriol causes
- hypercalcemia. Therefore, precaution should be taken when coadministration is necessary
- Ketoconazole may inhibit both synthetic and catabolic enzymes of calcitriol. Reductions in serum endogenous calcitriol concentrations have been observed following the administration of 300 mg/day to 1200 mg/day ketoconazole for a week to healthy men. However, in vivo drug
- interaction studies of ketoconazole with calcitriol have not been investigated
