How JYNARQUE works

Understanding ADPKD

How JYNARQUE® (tolvaptan) works

JYNARQUE works by targeting one of the hormones, vasopressin, that can cause cysts to grow in people with ADPKD

Vasopressin is a hormone that maintains the volume of water in the fluid space surrounding the cells.

Vasopressin Surrounding the Cell Receptor Vasopressin

People with ADPKD have too much vasopressin, causing kidney cysts to grow.

JYNARQUE Prevents Vasopressin from Binding to Receptor Receptor JYNARQUE

JYNARQUE works by preventing vasopressin from binding in the kidneys, making it harder for cysts to grow.

IMPORTANT SAFETY INFORMATION and INDICATION for JYNARQUE® (tolvaptan)

  • Serious liver problems. JYNARQUE can cause serious liver problems that can lead to the need for a liver transplant or can lead to death. Stop taking JYNARQUE and call your healthcare provider right away if you get any of the following symptoms:

  • before you start taking JYNARQUE
  • at 2 weeks and 4 weeks after you start treatment with JYNARQUE
  • then monthly for 18 months during treatment with JYNARQUE
  • and every 3 months from then on

Because of the risk of serious liver problems, JYNARQUE is only available through a restricted distribution program called the JYNARQUE Risk Evaluation and Mitigation Strategy (REMS) Program.

Do not take JYNARQUE if you:

  • have a history of liver problems or have signs or symptoms of liver problems, excluding polycystic liver disease
  • cannot feel if you are thirsty or cannot replace fluids by drinking

JYNARQUE may cause serious side effects, including:

  • Too much sodium in your blood (hypernatremia) and loss of too much body fluid (dehydration). In some cases, dehydration can lead to extreme loss of body fluid called hypovolemia. You should drink water when you are thirsty and throughout the day and night. Stop taking JYNARQUE and call your healthcare provider if you cannot drink enough water for any reason, such as not having access to water, or vomiting or diarrhea. Tell your healthcare provider if you get any of the following symptoms:
    • dizziness
    • fainting
    • weight loss
    • a change in the way your heart beats
    • feeling confused or weak

What should you avoid while taking JYNARQUE?

During the current COVID-19 pandemic, the JYNARQUE® (tolvaptan) REMS Program requirements remain in effect, as the health of patients who use this product is our top priority.
