NATPARA Patient Guide: How to Get Natpara at Low or No Cost

Important Notice: The NATPARA Special Use Program closed on December 31, 2025. As of 2026, NATPARA is no longer available through this or any Takeda patient assistance program. This guide provides historical context on the program for reference, but patients should consult healthcare providers for current hypoparathyroidism treatment options.[7]

About Natpara (Parathyroid Hormone)

Natpara is a prescription medication containing parathyroid hormone used to treat hypoparathyroidism, a rare condition where the parathyroid glands do not produce enough hormone, leading to low blood calcium levels. It helps maintain calcium balance when other treatments like calcium and vitamin D supplements are insufficient. Natpara was administered as a daily subcutaneous injection via a prefilled cartridge in a delivery device.[1][5]

Key risks: Natpara carries serious risks, including potential bone cancer (osteosarcoma), which is why it was subject to a strict REMS program (Risk Evaluation and Mitigation Strategy) required by the FDA. Only certified prescribers and pharmacies could prescribe and dispense it.[5][6]

Natpara was recalled in 2019 due to manufacturing issues but made available through a limited Special Use Program for patients facing life-threatening complications from discontinuation. This program supported a very small number of prior users.[1][7]

Who Qualifies for Assistance?

The NATPARA Special Use Program was not a traditional financial assistance program based on income. Instead, eligibility was extremely limited:

• Patients previously prescribed Natpara before the 2019 recall.
• Those facing life-threatening complications (e.g., severe hypocalcemia) due to stopping the drug.
• Requests made by healthcare providers only, not directly by patients.[1][7]

Takeda's Help at Hand program offered free medication to uninsured or underinsured patients for eligible products, but Natpara was not listed among them. General co-pay programs reduced costs to $5 per dose for eligible insured patients, but again, Natpara's restricted status excluded it.[2][3]

No broad income-based eligibility: Unlike standard PAPs (Patient Assistance Programs), there were no Federal Poverty Level (FPL) thresholds like 400% or 500% FPL. Qualification hinged on medical necessity under the Special Use Program.[1]

Income Eligibility Breakdown

Disclaimer: Table reflects the unique, non-financial criteria of the program. Standard Takeda programs like Help at Hand may apply income limits for other drugs (typically up to 400-500% FPL, varying by product), but not for Natpara.[2][3]

Insurance Requirements

Natpara required enrollment in the NATPARA REMS Program. Prescribers had to certify via training and submit forms; pharmacies verified certification and completed Patient-Prescriber Acknowledgment Forms.[5][6]

• No insurance? Help at Hand was for uninsured/underinsured, but Natpara unavailable.[2]
• Commercial insurance? Co-pay cards potentially reduced costs to $5/dose, but REMS/special use restrictions applied.[3]
• Government insurance (Medicare/Medicaid)? Not eligible for Takeda co-pay programs; patients directed to Extra Help or nonprofits.[9]

The Special Use Program bypassed typical insurance but was provider-initiated for emergencies.[1][7]

Step-by-Step Application Process

1. Consult your doctor: Discuss if you qualified (prior Natpara user with life-threatening issues). Only providers could request.[1]
2. REMS enrollment: Doctor completes online/paper certification at www.NATPARAREMS.com, Knowledge Assessment, and Prescriber Enrollment Form (fax 1-844-NAT-REMS or email NATPARAREMS@takeda.com).[5][6]
3. Patient forms: Complete Patient-Prescriber Acknowledgment Form with doctor; receive patient brochure.[6]
4. Special Use request: Provider contacts NATPARA Special Use Program manager at 1-866-888-0660 (Mon-Fri, 8 AM-? ET) to request access.[7]
5. Pharmacy verification: Certified pharmacy verifies prescriber/patient forms, fills prescription, and ships.[6]
6. Contact Takeda: For questions, call 1-855-NATPARA (1-855-628-7272).[1][6]

Post-2025: Program closed; work with your doctor on alternatives like high-dose calcium/vitamin D or clinical trials.[7]

Timeline and Delivery

• Processing: Varies; REMS forms faxed immediately, Special Use requests handled case-by-case for urgent needs.[6][7]
• Approval: Provider-led; anticipated for small number of patients quickly if eligible.[1]
• Delivery: Certified pharmacies contacted patients to arrange shipment after filling.[6]

Monthly supplies for ongoing needs under Special Use, but program ended Dec 31, 2025.[7][9]

Alternatives if Denied or Post-Closure

• Standard hypoparathyroidism treatments: Oral calcium, active vitamin D (calcitriol), magnesium supplements.[1]
• Takeda programs for other drugs: Help at Hand (free for eligible uninsured), Co-Pay ($5/dose).[2][3]
• Other resources: PAN Foundation, HealthWell Foundation for hypoparathyroidism; Medicare Extra Help.[9]
• Clinical trials: Search ClinicalTrials.gov for parathyroid hormone analogs.
• Provider support: Takeda's Patient Support at www.takedapatientsupport.com or 1-855-NATPARA.[4]
