Jynarque

Generic name: Tolvaptan

Usage of Jynarque

Jynarque is used to slow the decline in kidney function in adults who have autosomal dominant polycystic kidney disease.

Samsca is used to treat hyponatremia (low levels of sodium in your blood) in people with heart failure, and certain hormonal imbalances. Samsca improves urine flow without causing the body to lose too much sodium as you urinate.

Jynarque may also be used for purposes not listed in this medication guide.
