About BrandName

BrandName is a medicine from the vasopressin V2 receptor antagonist drug class. It is approved to treat low sodium in blood caused by heart failure, liver disease, or certain low blood conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH). It is also approved to slow kidney damage in polycystic kidney disease. BrandName works by blocking the water retention hormone, so the kidneys release more water without losing salt. Common side effects include thirst, frequent urination, dry mouth, liver problems, and dehydration. It should not be taken with grapefruit juice, as this changes how the drug works. People with liver disease, pregnancy, breastfeeding, or inability to sense thirst should avoid it. Overdose usually occurs above 300 mg and can cause severe dehydration, very high sodium levels, confusion, fainting, and liver injury.
