Dosage Guide

Quick Answer

Calcitriol's standard starting dose is 0.25 mcg once daily — with serum calcium and phosphate monitoring. The dose is adjusted by the doctor according to results. Self-dose adjustment is strictly forbidden — there is a risk of hypercalcaemia. In children the paediatric nephrologist decides. Missed dose: take when remembered, skip if next dose is soon, no double dose.
