GSK Patient Assistance Program Patient Guide: How to Get Twinrix at Low or No Cost

Twinrix is a vaccine that protects against both Hepatitis A and Hepatitis B, combining two recombinant vaccines into one convenient shot. The GSK Patient Assistance Program offers eligible patients free access to Twinrix when they meet specific financial and insurance criteria, helping those who can't afford this important protection.

About Twinrix

Twinrix is a prescription vaccine manufactured by GSK (GlaxoSmithKline) for active immunization against Hepatitis A virus and Hepatitis B virus infections. It's given as a series of three doses over six months to adults and children 18 months and older who are at risk, such as travelers to endemic areas, people with chronic liver disease, or those in high-risk occupations. Unlike separate vaccines, Twinrix streamlines protection with fewer injections. It's stored refrigerated and administered by healthcare providers. This guide focuses on getting it through the GSK program at no cost if you qualify.

Who Qualifies?

The program targets patients facing financial hardship with limited or no insurance coverage. Key requirements include:

  • U.S. residency (or Puerto Rico, with exceptions).
  • Proof of income showing household earnings below federal poverty guidelines (typically 400-500% of FPL, varying by category).
  • A valid prescription from a licensed prescriber.
  • Medicare Part D patients are not eligible for vaccine medicines like Twinrix.

Important note: This is a charitable program run by the independent GSK Patient Access Programs Foundation, not insurance. Availability depends on product supply and your situation.

Income Eligibility Breakdown

GSK uses sliding income thresholds based on household size and insurance status. While exact figures can update yearly, recent guidelines show these maximum annual gross income limits (before taxes). Provide proof like tax returns or pay stubs.

Household SizeUninsured (400% FPL)Underinsured (500% FPL)Low-Income (200% FPL)
1$58,650$73,300$28,800
2$79,290$99,300$36,000
3$99,930$124,800$43,200
4$120,570$150,200$50,400
Each additional+$20,640+$25,600+$7,200

These are illustrative based on program data; confirm current levels by calling (866) 728-4368 or visiting the application site, as they adjust with federal poverty levels.

Insurance Requirements

  • No or limited insurance: Ideal for uninsured or those with coverage that doesn't cover vaccines fully.
  • Medicare Part D exclusion: Patients on Medicare Part D cannot get vaccine medicines like Twinrix through this program.
  • Private insurance? Check GSK's copay programs first via gskforyou.com.
  • If insured, prove the vaccine isn't covered or unaffordable.

Step-by-Step Application Process

Applying is straightforward but requires your doctor's involvement. Multiple methods: online portal, phone, mail, or fax.

  1. Check eligibility: Use the "Get Started" tool at https://gskforyou.com/programs/patient-assistance-program/ or call (866) 728-4368 (Mon-Fri, 8am-8pm ET).

  2. Get prescriber registered: Your doctor must register at www.gskpatientassistanceportal.com before enrolling you.

  3. Gather documents:

    • Completed and signed application (download from site or request by phone).
    • Proof of income (e.g., last year's tax return, W-2s, pay stubs covering 4 weeks).
    • Government ID (copy of driver's license or passport).
    • Prescriber details: Signed original prescription for Twinrix (faxed only if from doctor's office with cover sheet), prescriber registration/certification, and shipping info.
  4. Submit: Fax to 1-855-474-3063, mail to PO Box 220590, Charlotte, NC 28222-0590, or use the online portal. Include patient name and DOB on all pages. Keep copies—originals aren't returned.

  5. Sign consents: Agree to GSK contacting your doctor/insurer for verification.

Tip: Incomplete apps delay processing. Double-check all sections, especially patient info (name, DOB, address, phone).

Timeline and Delivery

Processing takes 2-4 weeks typically, but can vary. Track by calling the helpline. If approved, Twinrix is shipped free to your prescriber's office (not directly to you), who administers it. Supply up to 12 months; prescribers certify medical need.

Alternatives if Denied

  • Appeal: Call (866) 728-4368 to discuss reasons (e.g., income too high, insurance issue) and resubmit.
  • Other programs: NeedyMeds.org, RxAssist.org, or state vaccine programs (e.g., Vaccines for Children for kids).
  • Copay help: GSKForYou copay cards if privately insured.
  • Free clinics: Federally Qualified Health Centers (FQHCs) or travel clinics may offer low-cost vaccines.
  • Public health: Local health departments for Hep A/B shots.
