About This Medication

Otsuka Patient Assistance Foundation Patient Guide: How to Get Samsca (tolvaptan) at Low or No Cost

Samsca (tolvaptan) is a prescription medication used to treat hyponatremia (low sodium levels in the blood) in certain adults, often due to conditions like heart failure, liver disease, or syndrome of inappropriate antidiuretic hormone secretion (SIADH). The Otsuka Patient Assistance Foundation (OPAF) offers eligible uninsured or underinsured patients free access to Samsca through a straightforward application process. This guide explains everything you need to know to apply successfully.

Who Qualifies for the Program?

The OPAF program helps U.S. residents who meet specific financial and medical criteria. You may qualify if you:

  • Live in the U.S. (a U.S. home address is required; citizenship is not).
  • Are uninsured or underinsured (e.g., your insurance denies coverage for Samsca).
  • Have a valid prescription for Samsca from a licensed healthcare provider.
  • Meet household income guidelines based on gross income (proof required for all household contributors).
  • Provide proof of residency and a confirmed diagnosis (often with ICD-10 code).

Important: This program is for patients with access barriers to Samsca. It's not for those with adequate insurance coverage. Always consult your doctor to confirm Samsca is right for you—it's typically short-term use due to risks like liver issues.

About Samsca (tolvaptan)

Samsca is a selective vasopressin V2-receptor antagonist that helps your kidneys remove excess water, raising sodium levels safely. It's FDA-approved for euvolemic or hypervolemic hyponatremia when oral meds are needed. Common doses are 15 mg or 30 mg tablets, taken once daily without food. Key warnings include liver toxicity (requires monitoring), thirst, and frequent urination. Do not use if pregnant, breastfeeding, or with certain conditions like urgent hyponatremia correction. Your doctor will monitor labs closely. For full details, review the prescribing information with your provider.

Income Eligibility Breakdown

OPAF requires proof of household gross income for all contributing members. Exact thresholds (e.g., Federal Poverty Level percentage) are not publicly detailed but based on specific criteria reviewed case-by-case. Submit one of these per household member:

  • Federal tax return (1040, etc.)
  • W-2 from prior year
  • 1099-MISC
  • 2 recent paystubs
  • Social Security award letter
  • Disability income info
  • Unemployment benefits letter
  • Employer letter on letterhead

Tip: Use the eligibility tool on www.otsukapatientassistance.com before applying. Income is verified strictly—incomplete proof delays approval.

Insurance Requirements

This program is for uninsured or underinsured patients. If insured:

  • Submit insurance denial proof, such as:
    • Explanation of Benefits (EOB)
    • Insurance statement
    • Prior authorization denial letter
  • Medicare patients may qualify if coverage is denied (common for limited-use drugs like Samsca).
  • No active commercial coverage that pays for Samsca? You're likely eligible.

OPAF ships medication directly to you at no cost if approved.
