Your doctor has prescribed NUCALA for you.

You took an important step by talking with your doctor about NUCALA. Through a review of your blood test results, symptoms and medication, your doctor determined that eosinophils may be a part of your severe asthma.

What's next?

You should know that filling your prescription will be a little different from what you may be used to.

  • Your doctor recommends NUCALA
  • Your insurance may approve NUCALA
  • Your specialty pharmacy ships NUCALA to your doctor.*
  • Your first injection is scheduled

*Your doctor may decide to order it directly for you, so you may not receive a call from the specialty pharmacy.

Before your prescription can be filled, your doctor or your specialty pharmacy will work through the approval process with your insurance company. In some instances, Gateway to NUCALA can help you understand your health insurance coverage. After you've been approved by your insurance company to receive NUCALA, a specialty pharmacy will send NUCALA directly to your doctor's office.

While this is how the process usually happens, your experience may be a bit different. Keep in mind that this takes time, so it may take several weeks to receive your first treatment with NUCALA.

At each step in the process, various members of your support team will be available to answer any of your questions.
