How to Find a Doctor Who Can Prescribe Zyflo Near You [2026 Guide]

If you've heard about Zyflo (zileuton) and want to find out if it might work for your asthma — especially if you have aspirin-exacerbated respiratory disease (AERD) or haven't responded well to other asthma medications — getting a prescription requires finding the right type of provider. This guide walks you through which doctors can prescribe Zyflo, how to find one near you, and what to bring to your appointment.

Who Can Prescribe Zyflo?

Zyflo (zileuton) is an FDA-approved prescription medication for chronic asthma. It is not a controlled substance. Any licensed prescriber — including physicians, nurse practitioners, and physician assistants — can legally prescribe it. However, because zileuton requires liver function monitoring and is typically reserved for patients with complex or treatment-resistant asthma, it is most commonly prescribed by specialists:

Allergists / Immunologists: The most likely prescribers. Allergists manage asthma extensively and are very familiar with leukotriene modifiers including zileuton. For AERD patients, allergists are the primary specialists to see.

Pulmonologists: Lung specialists who manage moderate-to-severe asthma often prescribe zileuton as an add-on therapy for patients whose symptoms aren't controlled by ICS or LABA alone.

Primary Care Physicians (PCPs): Can prescribe Zyflo, though many prefer to defer complex asthma cases to a specialist before initiating a medication with liver monitoring requirements.

Nurse Practitioners (NPs) and Physician Assistants (PAs): Licensed in most states to prescribe Zyflo, particularly in primary care or allergy/pulmonology practices.

Is Zyflo a Controlled Substance?

No. Zyflo (zileuton) is not a DEA-scheduled controlled substance. This means there are no special restrictions on who can prescribe it, no limits on refill frequency, and no requirement for in-person visits solely because of DEA rules. You can get a Zyflo prescription via telehealth without any special restrictions.

How to Find an Allergist or Pulmonologist Near You

If your primary care doctor hasn't been able to help, or you want to see a specialist for complex asthma, here are the best ways to find a provider:

Your insurer's provider directory: Log into your insurance portal and search for 'allergist' or 'pulmonologist' in your ZIP code to find in-network specialists.

ACAAI Find an Allergist: The American College of Allergy, Asthma & Immunology maintains a directory at acaai.org/find-an-allergist where you can search by ZIP code.

Zocdoc: Allows you to filter by specialty, insurance, and availability. Look for allergists or pulmonologists with asthma experience.

Ask your PCP for a referral: Your primary care physician can refer you to an in-network allergist or pulmonologist and often can help prioritize urgent appointments if your asthma is poorly controlled.

AERD specialists: If you suspect AERD (sensitivity to aspirin/NSAIDs with asthma and nasal polyps), look specifically for allergists who specialize in AERD. The Samter's Society website (samterssociety.org) maintains a list of AERD specialists nationwide.

Can I Get Zyflo Through Telehealth?

Yes. Because Zyflo is not a controlled substance, it can be prescribed via telehealth without any special in-person visit requirements. Several telehealth platforms offer asthma management consultations:

Teladoc, MDLive, or your insurer's telehealth benefit — general practitioners can evaluate your asthma and prescribe first-line medications.

Specialized telehealth allergy platforms — some telehealth companies focus specifically on allergy and asthma, and their providers are more familiar with zileuton.

Note: Because zileuton requires baseline and ongoing liver function tests (LFTs), the prescriber will likely want labs drawn before writing your first prescription. You can have these done at a local lab, then follow up with the telehealth provider once results are in.

What to Bring to Your Appointment

To make the most of your appointment and increase the likelihood of a Zyflo prescription, come prepared with:

A list of all current medications and supplements (especially any that interact with zileuton: theophylline, propranolol, warfarin)

Documentation of prior asthma treatments tried (ICS, montelukast, zafirlukast) and your response — including any failures or intolerances

A history of aspirin or NSAID reactions if you suspect AERD

Recent spirometry results if available

Notes on how often you use your rescue inhaler and any recent urgent care visits for asthma
