Eligible approved patients can get help with out-of-pocket costs.

Pay as little as $0 for NUCALA

Your healthcare team is your first line of support when you start NUCALA. But many other resources are available to help you start and stay on your treatment with NUCALA as prescribed.

Getting Started 

There are 2 ways to get started with the NUCALA Co-pay Program:

  1. You may work with your doctor to apply for the program through Gateway to NUCALA
  2. You may apply online at

How to Use the Co-pay Program

Once you have been approved for the Co-pay Program, how you use the Co-pay Program may be different depending on how you signed up and how you pay for your medicine.

You must be approved by your insurance company to take NUCALA before you can use the Co-pay Program.

Patients in government-funded programs (eg, Medicare, Medicaid, VA, or TRICARE) are not eligible for the NUCALA Co-pay Program.

With A Specialty Pharmacy

If you take NUCALA at home OR if you receive NUCALA in your doctor’s office and your doctor chooses to use a specialty pharmacy, a specialty pharmacy will call you monthly to collect your co-pay. Follow the 2 steps below to pay your co-pay with the NUCALA $0 Co-pay Program.

Step 1:

Provide the Rx Bin, Rx Group, and Member ID numbers on your monthly $25 Voucher to the specialty pharmacy.

Once complete, your remaining out-of-pocket cost for that month will be automatically loaded onto the Virtual Debit Card.

Step 2:

Provide the number on your Virtual Debit Card to the specialty pharmacy. The Virtual Debit Card will pay for the remaining co-pay amount (up to program maximum).

You will receive a new text or email in real time, each time your Virtual Debit Card has successfully been loaded.

It is especially important that you answer this call from the specialty pharmacy and then save this phone number into your contacts, so that it may be easier to recognize when it’s time to refill your prescription.
