Trying to conceive with an autoimmune condition can feel complicated.

You may be balancing symptom control, inflammation, medication safety, fertility treatment, and pregnancy planning all at once.

One of the biggest questions is:

Can I keep taking my medication while trying to get pregnant?

The answer depends on the medication, your diagnosis, your disease activity, your fertility timeline, and your care team’s recommendations.

Some autoimmune medications are generally considered compatible with conception and pregnancy.

Others may need to be stopped months before trying to conceive.

And some require a careful switch to a safer alternative before pregnancy.

The most important thing to remember is this:

Do not stop or change medication on your own.

Uncontrolled autoimmune disease can also increase pregnancy risks. For many people, the safest plan is not “no medication.” It is the right medication at the right time with the right monitoring.

This guide walks through eight key medication categories to review with your provider before conception or pregnancy.

Key Takeaways

  • Some autoimmune medications are considered compatible with conception and pregnancy.

  • Others, such as methotrexate, mycophenolate, leflunomide, and cyclophosphamide, are generally contraindicated because of pregnancy risks.

  • Disease control matters. A flare during conception or pregnancy can create risks too.

  • Washout periods may be needed before trying to conceive.

  • Your rheumatologist, OB-GYN, maternal-fetal medicine specialist, fertility doctor, and pharmacist may all need to coordinate.

  • Medication decisions should always be personalized.

Always consult your healthcare provider, rheumatologist, OB-GYN, maternal-fetal medicine specialist, fertility specialist, psychiatrist, or pharmacist before stopping, starting, or changing any medication before conception, during fertility treatment, during pregnancy, or while breastfeeding.

Why Medication Planning Matters Before Pregnancy

Autoimmune disease and pregnancy require careful planning.

The goal is usually to enter pregnancy with your condition as stable and well-controlled as possible.

This matters because active autoimmune disease may increase the risk of complications such as:

  • Flares

  • Pregnancy loss

  • Preterm birth

  • Hypertension

  • Growth restriction

  • Pain or disability

  • Organ involvement, depending on the condition

  • Medication changes during a sensitive time

At the same time, certain medications can affect embryo development or pregnancy safety.

That is why preconception planning is so important.

Ideally, your medication plan should be reviewed before you start trying to conceive.

This gives your care team time to:

  • Identify unsafe medications

  • Plan washout periods

  • Switch to safer alternatives

  • Stabilize disease activity

  • Coordinate fertility treatment

  • Create a pregnancy monitoring plan

  • Discuss postpartum flare prevention

1. Methotrexate

Methotrexate is commonly used for autoimmune and inflammatory conditions such as rheumatoid arthritis and psoriasis. It is also used in other medical settings, including certain cancer treatments and ectopic pregnancy management.

Pregnancy Safety

Methotrexate is contraindicated in pregnancy.

It is considered unsafe because it can interfere with folate metabolism and fetal development.

It has been linked with serious pregnancy risks and birth defects.

What to Consider Before Trying to Conceive

If you take methotrexate, talk with your provider well before trying to conceive.

Your care team may discuss:

  • When to stop methotrexate

  • How long to wait before conception

  • Whether your partner also needs guidance if he takes methotrexate

  • Folic acid supplementation

  • Safer alternatives for disease control

  • How to prevent a flare after stopping

Questions to Ask Your Doctor

  • When should I stop methotrexate before trying to conceive?

  • Do I need a washout period?

  • Should my partner stop methotrexate too?

  • How much folic acid should I take?

  • What medication can control my condition instead?

2. Mycophenolate Mofetil, Leflunomide, and Cyclophosphamide

Some medications used for severe autoimmune disease, organ involvement, or transplant-related conditions require extra caution before pregnancy.

This group includes:

  • Mycophenolate mofetil

  • Leflunomide

  • Cyclophosphamide

Pregnancy Safety

These medications are generally contraindicated during conception and pregnancy because of significant fetal risk.

They are not usually recommended when actively trying to conceive.

Why Planning Ahead Matters

These medications may require a carefully timed transition.

For example, leflunomide may require a specific washout process because it can stay in the body for a long time.

Cyclophosphamide may also affect fertility directly and may prompt fertility preservation discussions before treatment in some cases.

What to Consider

Before trying to conceive, ask your care team about:

  • Medication alternatives

  • Washout timing

  • Disease control during transition

  • Fertility preservation, if relevant

  • Pregnancy-safe treatment options

  • Specialist coordination

Questions to Ask Your Doctor

  • Is this medication safe while trying to conceive?

  • How long do I need to stop before pregnancy?

  • Do I need a washout protocol?

  • What safer medication can I switch to?

  • Should I see maternal-fetal medicine before trying?

3. Hydroxychloroquine

Hydroxychloroquine, often known by the brand name Plaquenil, is commonly used for conditions such as lupus, rheumatoid arthritis, and certain autoimmune skin or joint conditions.

Pregnancy Safety

Hydroxychloroquine is generally considered compatible with pregnancy for many patients.

It is commonly continued during pregnancy, especially in lupus, because it may help reduce disease flares and support better outcomes.

Why It May Be Continued

For some autoimmune conditions, stopping hydroxychloroquine may increase flare risk.

And flare prevention can be very important during pregnancy.

Your provider will weigh your diagnosis, dose, disease activity, and pregnancy plan.

What to Consider

Ask your doctor about:

  • Whether to continue hydroxychloroquine during conception

  • Dose adjustment, if needed

  • Eye monitoring if you are on long-term treatment

  • How it fits with your full pregnancy plan

  • Whether it should continue postpartum

Questions to Ask Your Doctor

  • Should I continue hydroxychloroquine while trying to conceive?

  • Is my dose appropriate for pregnancy?

  • Could stopping increase my flare risk?

  • Do I need additional monitoring?

  • Should I continue it while breastfeeding?

4. Sulfasalazine, Azathioprine, and Corticosteroids

Some autoimmune medications are commonly used during conception and pregnancy when needed for disease control.

This category includes:

  • Sulfasalazine

  • Azathioprine

  • Corticosteroids such as prednisone

Pregnancy Safety

These medications are often considered compatible with pregnancy when used appropriately and monitored.

However, dose, diagnosis, and side effects matter.

Sulfasalazine

Sulfasalazine may be used in rheumatoid arthritis, inflammatory bowel disease, and other inflammatory conditions.

Your provider may recommend folic acid supplementation when taking sulfasalazine.

Azathioprine

Azathioprine is used for conditions such as lupus, inflammatory bowel disease, vasculitis, and transplant-related immune suppression.

It is often used in pregnancy when the benefits outweigh the risks.

Your provider may consider enzyme testing, dosing, and monitoring.

Corticosteroids

Steroids can be useful for flares and inflammation control.

However, long-term or higher-dose steroid use may increase risks such as:

  • Gestational diabetes

  • High blood pressure

  • Infection risk

  • Bone health concerns

  • Weight changes

  • Mood changes

The goal is usually the lowest effective dose when steroids are needed.

Questions to Ask Your Doctor

  • Is this medication safe for conception and pregnancy?

  • Do I need extra folic acid?

  • Do I need dose adjustments?

  • What side effects should be monitored?

  • Is there a lower-risk medication option?

5. TNF-Alpha Inhibitors

TNF-alpha inhibitors are biologic medications used for autoimmune and inflammatory diseases.

Examples may include:

  • Infliximab

  • Adalimumab

  • Etanercept

  • Certolizumab

  • Golimumab

These may be used for conditions such as rheumatoid arthritis, Crohn’s disease, ulcerative colitis, psoriasis, psoriatic arthritis, and ankylosing spondylitis.

Pregnancy Safety

TNF-alpha inhibitors are often considered compatible with pregnancy when disease activity requires treatment.

However, the specific medication matters because different biologics cross the placenta differently, especially later in pregnancy.

Why Timing Matters

Your provider may discuss whether to continue throughout pregnancy or adjust timing near delivery.

This can affect:

  • Disease control

  • Baby’s immune exposure

  • Newborn monitoring

  • Vaccine timing after birth

Some biologics may influence when a baby can receive certain live vaccines.

This should be discussed with your OB and pediatrician.

Questions to Ask Your Doctor

  • Is my specific biologic safe while trying to conceive?

  • Should I continue during pregnancy?

  • Should the last dose be timed before delivery?

  • Will this affect my baby’s vaccine schedule?

  • What happens if I stop and flare?

6. Non-TNF Biologics and Small Molecule DMARDs

Some autoimmune medications have less pregnancy safety data.

These may include certain non-TNF biologics and small molecule disease-modifying drugs.

Examples may include:

  • Rituximab

  • JAK inhibitors

  • Abatacept

  • Tocilizumab

  • Other targeted immune therapies

Pregnancy Safety

These medications are often handled on a case-by-case basis.

Some may be avoided before conception unless the benefits clearly outweigh the risks.

Others may require a planned delay before trying to conceive.

Rituximab Consideration

Rituximab may affect B cells and immune function.

If used close to pregnancy, your provider may discuss possible effects on newborn immune function and monitoring.

What to Consider

Ask your care team about:

  • Drug clearance timing

  • Pregnancy safety data

  • Alternatives

  • Flare risk if stopped

  • Newborn monitoring

  • Breastfeeding safety

Questions to Ask Your Doctor

  • Is this medication safe before conception?

  • How long should I wait after my last dose?

  • Are there pregnancy-compatible alternatives?

  • What is the risk if I stop?

  • Will the baby need special monitoring?

7. NSAIDs

NSAIDs are nonsteroidal anti-inflammatory drugs used for pain and inflammation.

Common examples include:

  • Ibuprofen

  • Naproxen

  • Aspirin

  • Celecoxib, depending on the situation

Pregnancy Safety

NSAID safety depends on timing, dose, and reason for use.

Short-term use before conception or early in pregnancy may be allowed in some cases, but you should ask your provider.

NSAIDs are generally avoided later in pregnancy because of risks such as low amniotic fluid and effects on the baby’s heart circulation.

Low-dose aspirin is different from typical NSAID use and may be specifically recommended for some pregnancy-related conditions, but only under medical guidance.

Fertility Consideration

High-dose or frequent NSAID use around ovulation may affect follicle rupture in some people.

If you are actively trying to conceive, ask whether NSAIDs are appropriate during your fertile window.

Questions to Ask Your Doctor

  • Can I take ibuprofen or naproxen while trying to conceive?

  • Should I avoid NSAIDs around ovulation?

  • What pain relief is safest during fertility treatment?

  • Should I take low-dose aspirin, or should I avoid it?

  • What should I use for flare pain during pregnancy?

8. Lithium

Lithium is not an autoimmune medication, but it may come up in pregnancy planning for people with bipolar disorder or overlapping psychiatric and autoimmune care.

Mental health stability is an important part of pregnancy safety.

Pregnancy Safety

Lithium may carry pregnancy risks, including a small increased risk of certain heart defects.

However, stopping lithium abruptly can also be risky for some people due to relapse risk.

This decision should always be made with a psychiatrist and OB or maternal-fetal medicine specialist.

What to Consider

If lithium is part of your treatment plan, your provider may discuss:

  • Dose adjustment

  • Blood level monitoring

  • Kidney and thyroid monitoring

  • Fetal cardiac ultrasound

  • Postpartum relapse prevention

  • Breastfeeding considerations

Questions to Ask Your Doctor

  • Is lithium necessary for my stability during pregnancy?

  • What are the risks of continuing versus stopping?

  • Can the dose be adjusted?

  • What fetal monitoring is recommended?

  • How will we manage postpartum mental health risk?

Important Takeaways

Disease Control Matters

Uncontrolled autoimmune disease can be risky during conception and pregnancy.

A medication that keeps inflammation controlled may sometimes be safer than stopping treatment and triggering a flare.

Timing Is Everything

Some medications require weeks or months to clear before pregnancy.

Do not wait until a positive pregnancy test to ask about safety.

Safer Alternatives May Be Available

If your current medication is not pregnancy-compatible, your provider may be able to switch you to a safer option before you start trying.

Specialist Collaboration Is Key

Your care team may include:

  • Rheumatologist

  • OB-GYN

  • Maternal-fetal medicine specialist

  • Reproductive endocrinologist

  • Gastroenterologist

  • Dermatologist

  • Neurologist

  • Psychiatrist

  • Pharmacist

  • Pediatrician after birth

Newborn Planning May Matter

Certain medications, especially biologics, may affect newborn monitoring or vaccine timing.

Ask about this before delivery so your pediatrician has the full picture.

How to Apply This to Your Care

Before trying to conceive, create a medication plan with your providers.

Step 1: Make a Complete Medication List

Include:

  • Prescription medications

  • Over-the-counter medications

  • Supplements

  • Herbal products

  • Injections or infusions

  • Topical medications

  • As-needed medications

  • Medication doses and timing

Step 2: Ask About Each Medication

For every medication, ask:

  • Is this safe while trying to conceive?

  • Is this safe during pregnancy?

  • Is this safe during breastfeeding?

  • Does it require a washout period?

  • Is there a safer alternative?

  • What happens if I stop it?

Step 3: Create a Preconception Timeline

Your timeline may include:

  • Medication switches

  • Washout periods

  • Disease activity monitoring

  • Lab testing

  • Specialist visits

  • Fertility treatment planning

  • Pregnancy monitoring plan

Step 4: Coordinate Your Specialists

Make sure your fertility doctor and autoimmune specialist are on the same page.

This is especially important if you are doing IVF, using immune-modulating medications, or have a history of flares, pregnancy loss, or organ involvement.

Step 5: Plan for Pregnancy and Postpartum

Pregnancy is not the only period to plan for.

Postpartum flares can happen in some autoimmune conditions.

Ask your care team how medication, breastfeeding, sleep disruption, and disease monitoring will be handled after delivery.

Questions to Ask Your Provider

Bring these questions to your next appointment:

  • Are all my medications safe while trying to conceive?

  • Which medications need to be stopped or switched?

  • Do any require a washout period?

  • What pregnancy-safe alternatives are available?

  • Is my autoimmune condition stable enough for pregnancy?

  • Should I see maternal-fetal medicine before trying?

  • How will we monitor disease activity during pregnancy?

  • Will my medications affect fertility treatment?

  • Will any medications affect newborn vaccines?

  • What is the postpartum flare prevention plan?

Final Thoughts

Managing autoimmune disease while trying to conceive can feel overwhelming, but you do not have to figure it out alone.

The safest path is usually not guessing, stopping everything, or waiting until pregnancy happens.

The safest path is planning early.

Review your medications.

Ask about washout periods.

Discuss safer alternatives.

Coordinate your specialists.

And make sure your condition is as controlled as possible before pregnancy.

For many people with autoimmune disease, healthy conception and pregnancy are possible with the right plan.

Your medication plan should protect both your fertility goals and your long-term health.

You deserve a care team that helps you make informed, confident decisions every step of the way.
