What Is Tolvaptan Used For?

How Does This Medicine Work?

Tolvaptan works by blocking the effects of a hormone known as vasopressin. Vasopressin helps regulate the amount of water in the body. By blocking the effects of this hormone, tolvaptan causes more water to be removed as urine, without causing sodium to leave the body. This results in higher blood sodium levels. 
 

Can Children Use It?

This drug has not been approved for use in children (usually defined as individuals younger than 18 years old), as it has not been adequately studied in this age group. Talk to your child's healthcare provider about the risks and benefits of using tolvaptan in children.
 

Is It Safe for Older Adults to Use Tolvaptan?

Older adults can use this medication. In clinical studies, there were no differences in how well tolvaptan was tolerated or how it worked in older versus younger adults. However, some older adults may be more sensitive to the medication. Therefore, tolvaptan should generally be used with caution in older individuals.
 

What About Off-Label Uses?
