Your first treatment

Your doctor has prescribed NUCALA for you. What’s next?

You took an important step by talking with your doctor about NUCALA. Through a review of your blood test results, symptoms, exacerbation history, airflow, and medications, your doctor determined that eosinophils are a part of your severe asthma. You should know that filling your prescription will be a little different from what you may be used to.

Filling your prescription

Before your prescription can be filled, your doctor or specialty pharmacy will work through the approval process with your insurance company. During this process, your doctor, specialty pharmacy, or insurance company may need to call you to collect important information or payment. Be on the lookout for a call from your specialty pharmacy (you may not recognize the number), and be sure to respond to any voicemails they leave. Not doing so could delay your treatment. You can read more about this part of the process and learn about programs that can help on our Insurance info page.

After you’ve been approved by your insurance company to receive NUCALA, it will be shipped directly to your doctor’s office or your home depending on where you will take your injections. Keep in mind that this entire process takes time, so it may take several weeks to receive your first treatment of NUCALA.

NOTE: If you don’t have insurance coverage, you may qualify for our Patient Assistance Program.

Finding support

At each step in the process, various members of the support team will be available to answer your NUCALA questions. Your doctor’s office, Gateway to NUCALA (if services are requested), your insurance company, and your specialty pharmacy will work together to help you get your medication. Our patient support program, called MyNUCALA, also offers a Nurse Support* Line to answer any other questions you may have.

What to expect during your first treatment

At your doctor’s office

  • Your healthcare professional will prepare your injection.
  • You will receive an injection just underneath your skin (subcutaneously).
  • After your injection you may be asked to stay in the office so your doctor can monitor you for serious allergic reactions.
  • Sometimes serious allergic reactions, including anaphylaxis, can occur hours or days after administering NUCALA. See risks and side effects.

At home

  • Your doctor will provide you or your caregiver with information on injecting, including how to properly inject and education about monitoring for any allergic reactions, including anaphylaxis. Sometimes serious allergic reactions can occur hours or days later.
  • You will inject yourself underneath your skin (subcutaneously). Instructional videos, the full Instructions for Use, and other support for self-injection are available.

A few things to keep in mind as you continue your treatment with NUCALA

  • NUCALA is designed to work with your current asthma medications to reduce your severe asthma attacks. Don’t make any changes to your medications without first consulting your doctor.
  • If you receive NUCALA at your doctor’s office and miss an injection appointment for any reason, talk to your healthcare provider about getting back on track as soon as possible.
  • If you take NUCALA at home and miss an injection, you or your caregiver should inject a dose of NUCALA as soon as you remember. Then, continue (resume) your injections on your regular dosing schedule. If you do not notice that you have missed a dose until it is already time for your next scheduled dose, just inject the next scheduled dose as planned. If you are not sure what to do, ask your doctor, pharmacist, or nurse.
