Conivaptan, sold under the brand name Vaprisol, is a medication used to treat low sodium in those who either have normal or high total body fluid.[1] While it may improve lab values, it is unclear if it improves outcomes.[1] It is given by injection into a vein.[1]

Common side effects include pain at the site of injection, fever, low potassium, headache, and low blood pressure with standing.[1] Other side effects may include osmotic demyelination syndrome if sodium is corrected too rapidly.[2] Safety in pregnancy is unclear as is safety in heart failure.[2] It is a vasopressin receptor antagonist.[1]

Conivaptan was approved for medical use in the United States in 2005.[1] It has not been approved in the United Kingdom as of 2011.[3] In the United States it costs nearly 1,000 USD per 20 mg dose as of 2022.[4]
