# Getting Nucala (mepolizumab) at No Cost Through GSK For You: A Complete Patient Guide
---
Who Qualifies for the GSK For You (Patient Assistance Program)?
If you need Nucala (mepolizumab) but cannot afford it, you may be able to get it at no cost through the GSK For You Patient Assistance Program. This program is run directly by GlaxoSmithKline, the maker of Nucala. To give you a quick starting point: if you are a single-person household earning up to $90,360 per year, you may meet the income threshold. You must be either uninsured or underinsured — meaning your current insurance does not adequately cover Nucala's cost. Medicare Part D patients are not automatically excluded; some may qualify depending on their specific situation. If you meet both the income and insurance criteria, this program can provide Nucala to you at little or no out-of-pocket cost.

About Nucala (mepolizumab)
Nucala (mepolizumab) is an injectable prescription medication made by GlaxoSmithKline. It belongs to a drug class called interleukin-5 (IL-5) antagonist monoclonal antibodies. The FDA has approved Nucala to treat several conditions involving abnormal eosinophil activity, including severe eosinophilic asthma, eosinophilic granulomatosis with polyangiitis (EGPA), hypereosinophilic syndrome (HES), and chronic rhinosinusitis with nasal polyps (CRSwNP). Because Nucala is a specialty biologic medication, its list price can reach tens of thousands of dollars per year, placing it out of reach for many patients without adequate insurance coverage. No FDA-approved biosimilar versions of Nucala are currently available, which means there is no lower-cost generic alternative at this time.

Income Eligibility: Full Breakdown
The GSK For You program uses income thresholds set at approximately 600% of the Federal Poverty Level (FPL). The table below shows the maximum annual income allowed based on your household size:
| Household Size | Maximum Annual Income |
|---|---|
| 1 person | $90,360 |
| 2 persons | $122,640 |
| 3 persons | $154,920 |
| 4 persons | $187,200 |
If your household is larger than four people, the income limit typically increases for each additional member. Contact the program directly at (866) 728-4368 to confirm the limit for your household size.
If your income is above these limits, you do not automatically qualify for free medication through this program, but you should still review the alternatives listed later in this guide, including the manufacturer's savings card for insured patients.
Income is typically verified using your most recent federal tax return (Form 1040 or W-2), or if those are not available, three consecutive months of recent pay stubs. GSK reviews the documents you provide and makes the final eligibility determination. If your income fluctuates — for example, if you are self-employed or work seasonally — be prepared to explain your situation and provide the most accurate documentation you have.

What to Expect: Timeline and Delivery
Once your application is approved, GSK For You will notify you — and typically your prescribing physician's office as well. Nucala can be delivered either to your home or to your prescriber's office, depending on your preference and your doctor's setup. If the medication is sent to your prescriber, your care team will contact you to schedule your injection appointment. No additional payment is required at pickup or delivery for approved patients. Your enrollment in the program is not permanent — annual reauthorization is required. Before your benefit year ends, you will need to resubmit income documentation and a current prescription to confirm that you still qualify.

Alternatives If You Don't Qualify
If you do not meet the income or insurance criteria for the GSK For You program, there are still options worth exploring.
1. Biosimilars: There are currently no FDA-approved biosimilar versions of Nucala (mepolizumab) available in the United States. This option is not available at this time, but it may become available in the future.
2. GSK Nucala Savings Card (for insured patients): If you have commercial insurance, you may be eligible for a copay savings card that reduces your out-of-pocket costs. Visit https://www.nucala.com/nucala-gateway/copay-program/ for details.
3. State Pharmaceutical Assistance Programs (SPAPs): Many states run their own programs to help residents afford specialty medications. Eligibility and benefits vary by state. Contact your state's department of health or aging to ask about available programs.
4. NeedyMeds.org: This free, independent database (available at www.needymeds.org) lists hundreds of patient assistance programs, disease-based assistance funds, and other resources. It is a useful next step if other options do not work out.
