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).
