Are you suffering from kidney disease? Or does someone in your family have the condition? If so, your doctor may have told you about a vaccine called 'Calcitriol'. When you hear this, you may have a lot of questions. "What is this medicine?", "What does it do?", "Are there any side effects?" Don't worry, today we will talk about everything very simply and in a friendly way.
What is this Calcitriol?
Simply put, calcitriol is a special, active form of vitamin D. This medicine is mainly used to stop the calcium levels in the body from decreasing in people with kidney disease, and to bring them back to the proper level if they have decreased.
Think about it, calcium is like cement to our body. It is essential for strong bones, proper muscle function, and the functioning of the nervous system. When the kidneys are diseased, the body cannot use vitamin D properly. Then the calcium level decreases. That is when this Calcitriol injection helps.
Also, this medicine helps maintain the parathyroid hormone, which controls the calcium levels in our body, at the proper level.
Things you need to tell your doctor before using this medicine
It is very important to talk openly with your doctor about your health condition, so that he or she can give you the most appropriate and safest treatment. Be sure to mention the following points in particular:
- If your blood calcium or vitamin D levels are already high: This is essential as this medicine may increase those levels further.
- If you have an allergic reaction to vitamin D, calcitriol, or any other medicine, food, or dye: This is very important.
- If you are pregnant or trying to get pregnant: Some medications are not suitable during pregnancy, so talk to your doctor about this.
- If you are a breastfeeding mother: This should also be discussed, as medications can pass to the baby through breast milk.
