Merck Patient Assistance Program: The ACT Program Patient Guide: How to Get Pegintron (peginterferon alfa-2b) at Low or No Cost

Pegintron (peginterferon alfa-2b) is a prescription medication used to treat conditions like chronic hepatitis C and melanoma, and the Merck Patient Assistance Program (also known as The ACT Program) provides it free to eligible uninsured U.S. residents who meet income guidelines and cannot afford their medicine.[1][2][9]

This guide explains everything you need to know to apply, qualify, and get your medication. It's designed for patients like you—clear, step-by-step, and easy to follow. Always consult your doctor for medical advice.

About Pegintron (peginterferon alfa-2b)

Pegintron is an injectable form of interferon, a protein that helps your immune system fight viruses and certain cancers. It's FDA-approved for:

  • Treating chronic hepatitis C in adults and children (often with ribavirin).[9]
  • Adjuvant therapy for melanoma after surgery (as Sylatron, a related brand).[9]

It's given as a weekly subcutaneous injection, with dosing based on your body weight (e.g., up to 3 mcg/kg/week). Common side effects include flu-like symptoms, fatigue, depression, and blood count changes—your doctor will monitor these. Treatment duration varies: 6-12 months for hepatitis C or up to a year for melanoma.[9] If you're prescribed Pegintron, this program can make it accessible at no cost if you qualify.[1][6]

Who Qualifies for the Program?

To join the Merck Patient Assistance Program, you must meet all three key criteria:[3][7]

  1. U.S. Residency: Live in the U.S. (including territories like Puerto Rico); no citizenship required.[3][5]
  2. No Prescription Coverage: Uninsured for this medicine—no private insurance, Medicare, Medicaid, HMOs, veterans' aid, or state programs. Alternative funding plans that require PAP application as a prerequisite also disqualify you.[1][2][7]
  3. Financial Need: Household income below program limits, and you can't afford the medicine. Exceptions possible for hardships if income qualifies.[3][7]

Your doctor must prescribe Pegintron and complete part of the application.[3]

Income Eligibility Breakdown

Exact income thresholds aren't listed publicly for all programs and may update yearly—call 1-866-363-6379 for your current household size.[1] Based on recent examples for similar Merck programs, limits are around 400% of the Federal Poverty Level (FPL). Here's a sample table (verify by phone as FPL changes annually):[7]

Household SizeMax Annual Income (approx. 400% FPL)
1 (Individual)$63,840
2 (Couple)$86,560
3$109,280
4$132,000
+1 per member+$22,720

Notes: Income includes all household earnings. Program verifies via credit report or documents (won't hurt your credit). Special cases reviewed individually.[3]

Insurance Requirements

Uninsured only—no coverage for Pegintron from any source, including Medicare Part D, Medicaid, or employer plans.[2][7] If insured but facing high costs/hardship, request an exception (income must still qualify).[3][5] Avoid plans tying coverage to PAP denial.[1] Merck's Access Program can check insurance options first.[4][10]

Step-by-Step Application Process

Applications start by phone for Pegintron via The ACT Program—call 1-866-363-6379.[1] Here's how:

  1. Contact the Program: Call 1-866-363-6379 (or general Merck PAP at 800-727-5400). Confirm Pegintron eligibility and get forms.[3][5]
  2. Gather Documents: Prepare proof of income (e.g., tax return, pay stubs, 2 months' bank statements—one document often suffices).[3]
  3. Doctor Completes Form: Your healthcare provider (HCP) fills Section 5: signs, dates, adds NPI, and writes prescription (separate for controlled substances).[3]
  4. You Complete Your Part: Sign Sections 2/3; include residency proof if needed.[3]
  5. Submit: Mail to Merck Patient Assistance Program, PO Box 690, Horsham, PA 19044-0997 (or as instructed).[5] Phone apps may ship forms to you.[1]
  6. Verification: Program checks income/credit; approve/deny quickly.[3]

HCP can order up to 3-month supply + 3 refills (1 year total).[3][5]

Timeline and Delivery

Processing is typically fast—days to weeks, though not specified.[3] Once approved, medication ships to your home (or doctor's office if requested).[5] Up to 90-day supply per fill; refills as prescribed.[5] Enrollment lasts up to 12 months; reapply after.[3][5]

Alternatives if Denied

  • Appeal: If denied for insurance/hardship, request exception with doctor letter.[3]
  • Merck Access Program: Call for copay help or insurance navigation (if partially insured).[4][10]
  • Other PAPs: Check RxAssist.org or NeedyMeds for alternatives.[2]
  • State Programs: Veterans, Medicaid, or 340B clinics.[7]
  • Generic/Biosimilars: None listed for Pegintron.[9]
  • Patient Discount Cards: GoodRx for cash-pay (not free).[2]
