Tolvaptan is used to treat hyponatremia (low sodium in the blood) in patients with heart failure or syndrome of inappropriate antidiuretic hormone (SIADH).
Tolvaptan is also used to slow kidney function decline in adults who are at risk of rapidly progressing autosomal dominant polycystic kidney disease (ADPKD).
Sodium is a chemical that the body needs for it to function well. If you have a low sodium blood level, your body will not function normally and you may not feel well. Tolvaptan works in the kidneys to help maintain the right amount of sodium for the body.
