Let's take a minute to talk about your medication.

This is Calcitriol. This medicine contains a type of vitamin D. We get vitamin D mostly from sunlight, and from a few foods. Once vitamin D enters the body, the kidneys make it active so your body can use it.  People who have kidney disease, though, cannot make it active. Calcitriol gives your body vitamin D that does not need the kidneys. You should know that Calcitriol is not the same as vitamin D that you can buy without a prescription.

Vitamin D is important because it keeps a healthy balance of 3 things in your body -- calcium, phosphorus and a hormone called 'PTH'. Without vitamin D, these levels can become off balance and cause serious problems. These include weak bones, joint pain, heart attacks, skin problems, and more. 

Your doctor will order tests to check the levels of calcium, phosphorus and PTH in your blood. Your doctor may need to change your dose of Calcitriol. It is a delicate balance to make sure that the dose is not too much, or too little. 

For best results with Calcitriol, you should follow these 6 important steps:
- Take it exactly as your doctor tells you to. 
- Follow the exact diet that your doctor and dietician recommend. Remember - avoid foods and drinks that are high in phosphate.
- Take your other medicines exactly as directed. 
- Tell your kidney care team if you think you are having side effects. Side effects include a headache, stomach ache, nausea, constipation, and a metallic taste or dryness in your mouth. They also include feeling dizzy or tired.
- Always check with your kidney doctor before you take ANY vitamins, supplements or other medicines. 
- And, work closely with your kidney team to understand your condition and this medicine.
