Tolvaptan (brand name Jentadueto for ADPKD, or sold simply as Tolvaptan for hyponatremia) is a specialty drug, so its cost is higher than many generic or brand‑name medications.
Below is an approximate snapshot of what you might expect to pay in the United States—prices vary by pharmacy, insurance coverage, and whether you’re getting a single tablet or a full 30‑day supply.
| Use (Dosage) | Typical monthly supply | Approximate list price (US) |
|--------------|-----------------------|-----------------------------|
| ADPKD (Jentadueto) – 15 mg twice daily | 60 tablets | $4 000 – $6 000 |
| Hyponatremia – 7.5 mg once daily | 30 tablets | $3 500 – $5 500 |
| Other indications (e.g., heart failure) – 15 mg once daily | 30 tablets | $4 000 – $5 500 |
Key take‑aways:
* The average wholesale price (AWP) for a 30‑day supply typically falls in the $3,500–$6,000 range.
* Insurance: Most commercial plans list Tolvaptan as a “specialty” drug, often with higher copays or coinsurance (sometimes 20–30 % of the AWP). Medicare Part D plans may cover it, but you should check your specific formulary.
* Patient assistance: The manufacturer offers a Patient Assistance Program (PAP) for those who meet income criteria. Many community pharmacies also have “pharmacy discount cards” or “generic equivalents” that can reduce the out‑of‑pocket cost.
* Bulk purchasing: Some insurers negotiate a lower price for a 90‑day supply, so if you’re on a long‑term regimen, ask your pharmacy if a larger quantity is available at a reduced rate.
How to find your exact cost
1. Check your prescription benefit
* Look up the drug on your insurer’s website or contact their pharmacy benefit manager (PBM).
* Ask about any prior‑authorization requirements or step‑therapy plans that might affect cost.
2. Ask your pharmacist
* They can provide the Actual Cost (AC) at the pharmacy, which is often lower than the AWP.
* Pharmacists also know about local discount cards or coupon programs.
3. Explore patient assistance
* Visit the Tolvaptan/Paxil (Jentadueto) manufacturer website and fill out the assistance form.
* Contact the manufacturer’s support line for eligibility criteria.
Quick example
If you’re on a commercial plan with a 20 % coinsurance:
| Item | Cost |
|------|------|
| AWP for 30 tablets | $5,000 |
| 20 % coinsurance | $1,000 |
| Pharmacy discount (if available) | -$300 |
| Out‑of‑pocket | ≈$700 |
(These numbers are illustrative; your actual copay may differ.)

Bottom line:
Tolvaptan is expensive by specialty‑drug standards, usually costing $4 000–$6 000 per month before insurance. Your insurer, pharmacy, and manufacturer’s PAP are the best avenues to reduce the out‑of‑pocket expense. If you’re concerned about cost, bring up the discussion with your prescriber; they can sometimes provide a lower‑dose regimen or alternative therapy if appropriate.
