Hyponatremia vasopressin receptor antagonists (vaptans), such as conivaptan, may be slightly more effective than fluid restriction in those with high volume or normal volume hyponatremia. They should not be used in people with low volume. Their use in SIADH is unclear. Demeclocycline, while sometimes used for SIADH, has significant side effects including potential kidney problems and sun sensitivity. In many people it has no benefit while in others it can result in overcorrection and high blood sodium levels. Daily use of urea by mouth, while not commonly used due to the taste, has tentative evidence in SIADH. It, however, is not
Human serum albumin trauma, burns and surgery patients. A Cochrane systematic review of 37 trials found no evidence that albumin, compared with cheaper alternatives such as saline, reduces the risk of dying. Human serum albumin has been used as a component of a frailty index. It has not been shown to give better results than other fluids when used simply to replace volume, but is frequently used in conditions where loss of albumin is a major problem, such as liver disease with ascites. Human serum albumin may be used to potentially reverse drug/chemical toxicity by binding to free drug/agent. (Tatlow, D, Poothencheri, S,
