Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Calcitriol oral is taken by mouth.
Measure oral liquid carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Calcitriol injection is given as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Prepare an injection only when you are ready to give it. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.
You will need frequent medical tests.
Drink plenty of fluids unless your doctor has told you to restrict your fluid intake.
You may need to follow a special diet while using calcitriol. Follow all instructions of your doctor or dietitian. Learn about the foods to eat or avoid to help control your condition.
Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking calcitriol. This can lead to very low blood pressure, a serious electrolyte imbalance, or kidney failure.
If you need major surgery or will be on long-term bed rest, your dose or testing needs may change. Follow your doctor's instructions.
Store at room temperature away from moisture, heat, and light.
