Finding a Doctor Who Prescribes Leucovorin

Leucovorin (also known as Folinic Acid or by the brand name Wellcovorin) isn't a medication you'll get from a walk-in clinic or a quick telehealth visit. It's a specialized drug used alongside chemotherapy or to rescue patients from high-dose Methotrexate therapy. That means finding the right doctor is the first — and most important — step to getting the treatment you need.

Whether you've been newly diagnosed with colorectal cancer, you're starting Methotrexate for another condition, or you've been referred for Leucovorin rescue therapy, this guide will walk you through exactly how to find a prescribing provider near you in 2026.

What Type of Doctor Prescribes Leucovorin?

Leucovorin is prescribed by specialists, not general practitioners. The type of doctor you need depends on why you need the medication:

• Oncologists and Hematologists — The most common prescribers. If you need Leucovorin as part of a chemotherapy regimen (such as with 5-Fluorouracil for colorectal cancer), a medical oncologist will manage your treatment.
• Rheumatologists — If you're on high-dose Methotrexate for rheumatoid arthritis or another autoimmune condition, your rheumatologist may prescribe Leucovorin to reduce side effects.
• OB/GYN Specialists — For ectopic pregnancy treated with Methotrexate, your OB/GYN may prescribe Leucovorin as a follow-up rescue agent.
• Infectious Disease Specialists — Leucovorin is sometimes used alongside Pyrimethamine to treat toxoplasmosis, particularly in HIV/AIDS patients.
• Emergency Medicine and Toxicology Physicians — In cases of Methotrexate overdose or methanol poisoning, emergency doctors may administer Leucovorin in the hospital setting.

In most cases, you'll need a referral from your primary care doctor to see one of these specialists.

How to Find a Provider Near You

Once you know what type of specialist you need, here are the best ways to find one:

1. Use Your Insurance Provider Directory

Start with your health insurance company's online directory. Most insurers let you search by specialty and location. This ensures the doctor you find is in-network, which can save you hundreds or even thousands of dollars on specialist visits and treatment costs.

Log in to your insurer's website or call the member services number on your insurance card. Ask specifically for oncologists, rheumatologists, or the relevant specialty in your area.

2. Ask Your Primary Care Doctor for a Referral

Your primary care physician (PCP) is often the best starting point. They can:

• Refer you to a trusted specialist they've worked with before
• Send your medical records ahead of time
• Help expedite the referral if your insurance requires one

If you're dealing with a cancer diagnosis, your PCP may refer you directly to a cancer center that has oncologists experienced with Leucovorin-based regimens.

3. Search on Zocdoc or Healthgrades

Online doctor-finding platforms like Zocdoc, Healthgrades, and Vitals let you search by specialty, insurance accepted, and location. You can read patient reviews and often book appointments online.

Search for "oncologist" or "hematologist" in your ZIP code, then filter by insurance. While these platforms won't specifically list "Leucovorin prescribers," any board-certified oncologist treating colorectal cancer will be familiar with the drug.

4. Contact a Cancer Center Directly

If you need Leucovorin as part of cancer treatment, consider reaching out to an NCI-designated cancer center or a large hospital system near you. These centers have multidisciplinary teams and are more likely to have Leucovorin in stock or access to it through their specialty pharmacy.

5. Telehealth Limitations

Unlike many medications, Leucovorin is not well-suited for telehealth prescribing. Here's why:

• The injectable form must be administered in a clinical setting (hospital or infusion center)
• Treatment requires lab monitoring (blood counts, methotrexate levels)
• Most Leucovorin regimens are part of complex treatment plans that need in-person oversight

That said, a telehealth consultation with an oncologist or specialist can be a good first step to discuss your diagnosis and determine whether Leucovorin is appropriate for you before scheduling in-person treatment.

What to Expect at Your Appointment

When you see a specialist about Leucovorin therapy, here's what typically happens:

• Medical history review — The doctor will review your diagnosis, prior treatments, and any allergies (especially to Folic Acid or Leucovorin).
• Lab work — Blood tests to check kidney function, blood counts, and possibly Methotrexate levels if you're being treated with that drug.
• Treatment plan discussion — Your doctor will explain when and how Leucovorin will be given, whether orally or by IV, and how it fits into your overall treatment.
• Side effects counseling — You'll learn about potential side effects of Leucovorin, including nausea, diarrhea, and the rare risk of allergic reactions.
• Scheduling — If you need IV Leucovorin, you'll schedule your infusion sessions at the hospital or clinic.

Bring a list of all medications and supplements you currently take. Leucovorin has important drug interactions your doctor needs to know about.

After You Get Your Prescription

Once your doctor prescribes Leucovorin, filling the prescription can be its own challenge. Leucovorin has been in and out of shortage since 2008, and both injectable and oral forms can be hard to find in 2026.

Here's what to do after your appointment:

• Ask your doctor's office for help — Many oncology offices have pharmacy coordinators who can track down Leucovorin or arrange for a specialty pharmacy to supply it.
• Check availability online — Use Medfinder to see which pharmacies near you have Leucovorin in stock right now.
• Consider the generic — Leucovorin Calcium is available as a generic from manufacturers like Teva and Fresenius Kabi. Generic tablets can cost as little as $24 to $36 for a supply of twelve 5 mg tablets with a discount card.
• Look into financial assistance — If cost is a concern, programs like Prescription Hope offer brand Wellcovorin for $70 per month. Learn more in our guide to saving money on Leucovorin.

Final Thoughts

Finding a doctor who can prescribe Leucovorin starts with understanding which specialist you need. For most patients, that means an oncologist, rheumatologist, or another specialist managing your underlying condition. Use your insurance directory, ask for a referral, and don't hesitate to reach out to cancer centers directly.

Once you have your prescription, Medfinder can help you find a pharmacy with Leucovorin in stock — so you can focus on your treatment, not on tracking down your medication.
