Calcitriol 1mcg/1mL Injection

Product Introduction

Calcitriol 1mcg/1mL is an injectable form of calcitriol, the active form of vitamin D. Calcitriol helps the body absorb calcium, supports bone mineral balance, and suppresses excess parathyroid hormone. Too much calcitriol can cause hypercalcemia, which may present with nausea, vomiting, constipation, weakness, thirst, frequent urination, confusion, or abnormal heart rhythm. This injection is for healthcare-professional use and should be reviewed alongside calcium supplements, vitamin D products, thiazide diuretics, digoxin, magnesium products, and phosphate binders.

How to use

Calcitriol 1mcg/1mL is given intravenously by healthcare staff, often in a renal-care or dialysis setting. Blood calcium, phosphorus, parathyroid hormone, and related medicines should be monitored. Do not add extra calcium or vitamin D unless the clinician advises it.

How it works

Calcitriol binds vitamin D receptors, increasing intestinal calcium absorption and helping regulate calcium, phosphorus, and parathyroid hormone balance.

Common side effects

Possible effects are often linked to high calcium and include nausea, vomiting, constipation, weakness, headache, thirst, frequent urination, dry mouth, metallic taste, confusion, or muscle pain. Serious concerns include severe hypercalcemia, high phosphorus, kidney-stone risk, calcification problems, and abnormal heart rhythm.

Important information

Monitoring is essential. Tell the care team about high calcium, high vitamin D levels, kidney stones, heart rhythm medicines such as digoxin, calcium supplements, vitamin D products, magnesium antacids, phosphate binders, pregnancy, and breastfeeding.
