Sometimes your doctor may tell you that your sodium level is low. This is medically known as hyponatremia. In such cases, when the sodium level in the body is low, we are going to talk about a special injection that is given to treat it. It is called Conivaptan. This is not a medicine that you would usually take home, but a medicine that is given in a hospital under the supervision of a doctor. Let's see the details about this.
What kind of medicine is this Conivaptan?
Okay, let's put this simply. When your sodium levels drop, it means that the amount of sodium in your body decreases relative to the amount of water in your body. The Conivaptan injection does a wonderful job.
Simply put, this medicine helps your kidneys to remove excess water from your body through urine . But at the same time, it also helps to retain the sodium salt that your body needs. In this way, this medicine helps to restore the balance between water and sodium in your body. That is, it brings the sodium level in your body back to a healthy level.
This medicine may sometimes be used for other medical purposes. If you have any questions about this, you can ask your doctor.

Before you are given the Conivaptan vaccine, your healthcare team will need to know your complete medical history. This is because it can be dangerous to use this medicine with certain medical conditions. Therefore, if you have any of the conditions listed below, you should tell your doctor.
