Releuko is typically prescribed by oncologists and hematologists. Here's how to find the right specialist who can prescribe filgrastim-ayow near you in 2026.

Releuko (filgrastim-ayow) is a prescription-only specialty biologic used in oncology, hematology, and related fields. Unlike a common antibiotic or blood pressure medication, it requires a prescriber who understands your specific medical context — most commonly cancer treatment, bone marrow conditions, or a diagnosis of chronic neutropenia. This guide explains who can prescribe Releuko, how to find the right specialist, and what your options are if access to care is difficult.

Who Can Prescribe Releuko?

Any licensed physician, nurse practitioner (NP), or physician assistant (PA) can technically prescribe Releuko in most U.S. states. However, Releuko is a specialty oncology medication and is most commonly initiated and managed by:

Medical oncologists — Most common prescribers. Oncologists prescribe Releuko to cancer patients receiving myelosuppressive chemotherapy to prevent or treat febrile neutropenia.

Hematologists — Treat blood disorders including AML, severe chronic neutropenia, and bone marrow failure syndromes.

Pediatric oncologists and hematologists — For children with severe chronic neutropenia (congenital, cyclic, or idiopathic).

BMT/transplant specialists — Prescribe Releuko to support neutrophil recovery after bone marrow transplant.

Primary care physicians (PCPs) — May manage ongoing chronic neutropenia therapy after initial diagnosis by a hematologist.

Why You'll Typically Need a Specialist

Releuko is not a medication primary care doctors prescribe as a first point of contact. Your care pathway usually starts with a diagnosis that requires it. For example:

If you're undergoing chemotherapy, your oncologist will prescribe Releuko as part of your treatment plan.

If you have a blood disorder or bone marrow condition, your hematologist will manage Releuko as part of your ongoing care.

If you have congenital, cyclic, or idiopathic neutropenia, you'll likely need a hematologist to diagnose and initiate therapy, with possible ongoing management by a PCP.

How to Find an Oncologist or Hematologist Near You

Here are the best resources to find a specialist who can prescribe Releuko:

ASCO's Cancer.net Find a Cancer Doctor: cancer.net/find-cancer-doctor — Searchable database of ASCO-affiliated oncologists by location and specialty.

NCI-designated Cancer Centers: cancer.gov — NCI-designated centers have oncologists and hematologists experienced with specialty biologics.

Your insurance plan's provider directory: Use the "Find a Provider" tool on your insurance company's website and filter by specialty: "Medical Oncology" or "Hematology."

Ask your primary care doctor for a referral: Your PCP can refer you to an in-network oncologist or hematologist and can often expedite the referral if your condition is urgent.

Telehealth and Releuko: What You Need to Know

Telehealth has significantly expanded access to specialist care, but there are important limitations when it comes to Releuko:

Most new cancer diagnoses require in-person evaluation, imaging, and labs before a prescriber can initiate Releuko.

For established patients with chronic neutropenia managing home-administered Releuko, telehealth follow-up appointments are increasingly common and can be used for dose adjustments and lab review.

Telehealth oncology platforms such as Teladoc Health, Included Health, and cancer-specific platforms can connect patients with oncologists remotely for medication management.

What to Bring to Your First Appointment

When you see a specialist who may prescribe Releuko, bring:

Your complete medical history including diagnosis and prior treatment records

Recent CBC (complete blood count) results showing neutrophil counts

Your insurance card and a list of current medications

Any prior experiences with G-CSF therapy (doses, response, side effects)

Once you have your prescription, use medfinder to locate pharmacies near you that have Releuko in stock. See our guide on how to find Releuko in stock near you for step-by-step instructions.

Frequently Asked Questions

Technically yes — any licensed prescriber can write a Releuko prescription. However, in practice, Releuko is almost always prescribed by medical oncologists or hematologists in the context of cancer treatment or a blood disorder. Your PCP can refer you to the appropriate specialist if you haven't already been diagnosed.

Not necessarily. Once your treatment is established, many patients with ongoing therapy (especially those with chronic neutropenia) can manage refills through periodic telehealth check-ins with their specialist or routine follow-up visits. Your prescriber will determine the monitoring schedule based on your condition and lab values.

Yes, nurse practitioners (NPs) and physician assistants (PAs) can prescribe Releuko in most U.S. states, particularly when they are part of an oncology or hematology practice. The specific scope of practice for NPs and PAs varies by state law.

Telehealth is more useful for follow-up and medication management than for initial diagnosis of the conditions that require Releuko. New cancer diagnoses require in-person evaluation. However, established patients with chronic neutropenia may be able to manage ongoing Releuko therapy through telehealth visits with their hematologist.

After your specialist writes the prescription, expect 3–10 days for insurance prior authorization to be processed for specialty biologics. Your oncology team's prior authorization staff can expedite this. If your treatment is urgent, ask about obtaining a short supply through your clinic's buy-and-bill stock while the PA is being processed.
