Question:
A female patient with rheumatoid arthritis(RA) is currently on methotrexate (MTX), sulfasalazine (SSZ), and hydroxychloroquine (HCQ) and is planning for pregnancy. What is the appropriate next step in medication management?

Show Hint
Remember the "Safe in Pregnancy" DMARDs: Hydroxychloroquine, Sulfasalazine, Azathioprine, and Cyclosporine/Tacrolimus. The "Absolutely Contraindicated" DMARDs: Methotrexate, Leflunomide (requires cholestyramine washout), Mycophenolate Mofetil, and Cyclophosphamide.
Updated On: Sep 3, 2026
- Stop MTX and sulfasalazine, add low dose steroids with HCQ
- Stop only MTX, continue sulfasalazine and HCQ
- Stop all DMARDs and only give steroids
- Switch to biologics

The Correct Option is B
Solution and Explanation
Concept:
This question evaluates the knowledge of drug safety profiles during conception and pregnancy for patients with Rheumatoid Arthritis on a standard triple-therapy DMARD regimen.
The goal is to maintain disease control while strictly avoiding teratogenic medications.
Explanation:
• Methotrexate (MTX) is highly teratogenic. It acts as a folate antagonist and can cause neural tube defects, craniofacial abnormalities, and limb defects (Methotrexate embryopathy). It is absolutely contraindicated in pregnancy and must be discontinued at least 1 to 3 months prior to attempted conception.
• Sulfasalazine (SSZ) is generally considered safe during pregnancy and conception. It does not cause congenital malformations, though high doses may require folic acid supplementation due to mild anti-folate properties.
• Hydroxychloroquine (HCQ) is safe and highly recommended to be continued throughout pregnancy in patients with systemic autoimmune diseases (like SLE and RA). It helps maintain remission and prevent flares during pregnancy without fetal harm.
• Therefore, the correct approach is to discontinue only the teratogenic agent (MTX) and maintain the safe agents (SSZ and HCQ) to prevent a disease flare.
Final answer:
Methotrexate is teratogenic and must be stopped, whereas Sulfasalazine and Hydroxychloroquine are safe and should be continued to control the RA.
