If you live with rheumatoid arthritis or another autoimmune condition and you’re trying to get pregnant — or you’re already expecting — you’ve probably asked yourself this question: Is it safe to stay on Humira during pregnancy?

It’s one of the most common questions patients bring to our Chicago rheumatology practice, and the answer often surprises people. For many patients, stopping Humira too early can actually be riskier than continuing it.

Below, we break down what current research and FDA guidance say about adalimumab (Humira) use during conception, pregnancy, and breastfeeding — and why working closely with your rheumatologist is the key to a safe, healthy outcome for both you and your baby.

Why This Question Matters

Autoimmune disease management during pregnancy has changed a lot over the years. In the past, many doctors automatically recommended stopping biologic medications like Humira as soon as a patient became pregnant. Today, we know that approach isn’t always the safest one.

Thanks to years of published research, clinical experience, and updated FDA guidance, we now understand that:

  • Well-controlled autoimmune disease is one of the biggest predictors of a healthy pregnancy
  • Some biologics, including Humira, carry a relatively low risk profile during pregnancy
  • Uncontrolled disease activity can pose a greater risk to mother and baby than the medication itself

Is Humira Safe While Trying to Conceive?

Yes — for most patients, Humira (adalimumab) can generally be continued safely while trying to become pregnant.

Getting your rheumatoid arthritis or autoimmune disease into remission or well-controlled before conception is one of the most important steps you can take for a healthy pregnancy. Flares during pregnancy can be harder to manage and may carry their own risks, so staying on effective treatment leading up to conception is often the safer path.

What Happens to Humira Exposure During Pregnancy?

Not all trimesters are the same when it comes to medication crossing the placenta.

First and Second Trimester

During the first half of pregnancy, very little Humira crosses the placenta. This means early exposure is generally not considered a major concern for your baby’s development.

Third Trimester

Later in pregnancy — particularly the third trimester — more of the medication can cross to the baby. This is where treatment decisions become more individualized:

  • If your disease is in remission or well-controlled, your rheumatologist and OB may discuss pausing Humira around the third trimester to reduce fetal exposure.
  • If your rheumatoid arthritis or autoimmune disease is still active, continuing Humira through delivery is often the better choice, since uncontrolled inflammation can pose more risk than the medication itself.

There’s no one-size-fits-all answer here — this decision should always be made together with your care team based on your specific disease activity.

Is Humira Safe While Breastfeeding?

Good news for new moms: Humira is generally considered compatible with breastfeeding.

Only a very small amount of the medication may pass into breast milk, and it’s not expected to significantly affect your baby. This allows many mothers to continue their treatment while breastfeeding without added worry.

One Important Note for Your Baby’s Pediatrician

If you continued Humira during the second half of pregnancy, be sure to tell your baby’s pediatrician.

Why does this matter? The medication can remain in your baby’s system for a period of time after birth, which means certain live vaccines may need to be delayed during the first several months of life. Your pediatrician will guide you on the right vaccine schedule based on your treatment history.

The Key to a Safe Pregnancy: Coordinated Care

Managing autoimmune disease during pregnancy isn’t something you should navigate alone — and it’s not something one doctor should manage in isolation either. The safest outcomes happen when your:

  • Rheumatologist
  • Obstetrician
  • Pediatrician

are all communicating and aligned on your treatment plan. This team-based approach ensures that decisions about starting, continuing, or pausing Humira are made with your full health picture in mind — protecting both you and your baby every step of the way.
