Biologic Not Working? Why Your Chicago Rheumatologist May Keep You on Methotrexate

If you live with inflammatory arthritis, you may have been through more than one medication. Maybe you started a biologic, it helped for a while, and now your joints are flaring again.

When your doctor recommends switching to a new treatment, they may also ask you to keep taking methotrexate. That can feel confusing. If the plan isn’t working, why keep part of it?

This article explains the reasons in plain language. Trusted Arthritis Treatment Chicago patients rely on this kind of guidance to feel confident about their care.

What Is Inflammatory Arthritis?

Inflammatory arthritis is a type of autoimmune disease. Your immune system normally protects you from infections. In autoimmune arthritis, it attacks your own joints by mistake, and sometimes other organs too.

Common types include:

• Rheumatoid arthritis (RA)
• Psoriatic arthritis
• Ankylosing spondylitis and related conditions

Without treatment, this ongoing inflammation can cause pain, stiffness, swelling, and lasting joint damage.

How Doctors Treat It: Disease-Modifying Medications

The standard of care for autoimmune disease treatment is a group of drugs called disease-modifying treatments. These medications calm and adjust the immune system so it stops attacking your joints.

They do more than relieve pain. They help slow or prevent damage over time.

Why Methotrexate Is a Cornerstone of Arthritis Care

Methotrexate has been used in rheumatology since the mid-1980s. Studies from that time showed it works well for rheumatoid arthritis, and it has remained a foundation of arthritis care ever since.

It Works Well for Many Patients

For a meaningful share of people with RA, methotrexate alone controls the disease. In the experience of our Chicago rheumatologist, roughly 40% of RA patients do well on methotrexate by itself.

The rest usually need something stronger added, such as a biologic medication.

It Makes Biologics Work Better

Many of the original studies on biologic medications found that patients did better on a biologic plus methotrexate than on the biologic alone. There are two main reasons:

• Teamwork effect: Two medications that work in different ways can produce a stronger result together.
• Antibody protection: Your body can sometimes make antibodies against a biologic drug. These antibodies can make the biologic less effective over time. Methotrexate may help prevent this, so the biologic lasts longer and works better.

It Is Affordable

Cost matters for patients. Methotrexate is very inexpensive, often just pennies per tablet. Biologic medications can cost thousands of dollars per month.

Because methotrexate is effective, works well in combination, and is low cost, it remains one of the most widely used arthritis medications.

Why Keep Methotrexate When Switching Biologics?

Say you’ve tried one or two biologics and your arthritis still isn’t fully controlled. Your rheumatology specialist recommends a new medication. Here’s why continuing methotrexate often makes sense.

1. You Stay Protected During the Gap

Starting a new biologic isn’t always quick. Insurance prior authorization can cause delays of days or weeks.

During that time, it’s important to have something working to control inflammation. Stopping everything could raise your risk of a flare.

2. It May Help Your Next Treatment Succeed

The same benefits apply to your next biologic. Methotrexate may:

• Boost how well the new medication works
• Lower the chance your body forms antibodies against it
• Help the new treatment stay effective longer

3. It Keeps Your Treatment Plan Steady

Continuing a medication you already tolerate gives your care team a stable base while they adjust other parts of your plan.

Questions to Ask Your Rheumatologist

If you’re switching treatments, consider asking:

• Should I keep taking methotrexate while I wait for my new medication?
• How long might the approval process take?
• What should I do if I have a flare during the switch?
• How will we know if the new treatment is working?

Never stop or change a medication on your own. Your doctor can explain what’s right for your situation.

A Whole-Person Approach to Joint Pain Relief

Controlling inflammation with medication is the foundation of treating autoimmune arthritis. Many patients also deal with joint wear, cartilage damage, or chronic pain alongside their autoimmune condition.

At Chicago Arthritis and Regenerative Medicine, care can include:

• Rheumatology care for autoimmune and inflammatory arthritis
• Osteoarthritis treatment for wear-and-tear joint problems
• Regenerative medicine Chicago options, such as PRP therapy, for appropriate joint conditions
• Chronic pain management strategies tailored to your goals

Regenerative treatments do not replace disease-modifying medications for autoimmune arthritis. Your doctor can help you understand which options may fit your needs.
