Folic Acid, Turmeric, and Hydroxychloroquine (Plaquenil) in Rheumatoid Arthritis During Pregnancy Planning
Yes, folic acid works safely with hydroxychloroquine (Plaquenil) and should be taken together, but turmeric supplements should be avoided due to lack of safety data during pregnancy planning and pregnancy. 1, 2
Hydroxychloroquine (Plaquenil) During Pregnancy Planning
The American College of Rheumatology strongly recommends continuing hydroxychloroquine throughout pregnancy planning and pregnancy. 1, 2
- Hydroxychloroquine should be continued at your current dose (typically 200-400 mg daily) without interruption when planning pregnancy or after becoming pregnant 2, 3
- Stopping hydroxychloroquine when planning pregnancy or after conception can precipitate dangerous disease flares and increase maternal complications without providing any fetal benefit 2
- Recent high-quality evidence from a 2025 Swedish population-based cohort study found no increased risk of major congenital malformations with first-trimester hydroxychloroquine exposure (adjusted risk ratio 1.30,95% CI: 0.76-2.23) 4
- Hydroxychloroquine reduces lupus flares during pregnancy and decreases rates of preterm birth and intrauterine growth retardation 2
Folic Acid Supplementation - Essential and Compatible
You should take 0.4-0.8 mg (400-800 mcg) of folic acid daily starting now and continuing throughout pregnancy. 5
- The US Preventive Services Task Force recommends 0.4-0.8 mg daily for all women planning pregnancy to prevent neural tube defects 5
- Folic acid is completely compatible with hydroxychloroquine - there are no drug interactions between these medications 6
- Start folic acid supplementation at least 3 months before attempting conception and continue throughout pregnancy 7
- Some rheumatologic medications (like sulfasalazine) specifically require folic acid supplementation due to folate absorption interference, making this combination routine in rheumatology practice 7
Turmeric (Curcumin) Supplements - Should Be Avoided
Turmeric/curcumin supplements should be discontinued when planning pregnancy due to insufficient safety data. 1, 8
- There is no available evidence regarding the safety of turmeric supplements during pregnancy planning or pregnancy 1, 8
- The American College of Rheumatology and other major rheumatology societies do not include turmeric in their pregnancy-compatible medication lists 1, 2
- Unlike hydroxychloroquine and folic acid, which have extensive safety data in pregnancy, turmeric lacks the rigorous evidence needed to recommend its use 8, 9
Critical Importance of Disease Control
Active rheumatoid arthritis during pregnancy poses greater risks than pregnancy-compatible medications. 10
- High disease activity in RA is significantly associated with increased risk of cesarean delivery (OR: 2.29) and premature delivery (OR: 5.61) 10
- RA women have higher odds of preeclampsia, gestational diabetes, spontaneous abortion, and their infants show higher risk of stillbirth, small for gestational age, and low birth weight 10
- Maintaining disease control with safe medications like hydroxychloroquine is the appropriate clinical decision, as uncontrolled disease activity poses greater risk than medication exposure 2, 8
Common Pitfall to Avoid
Do not discontinue hydroxychloroquine when planning pregnancy or after a positive pregnancy test. 2
- This is the most common and dangerous mistake made by patients and providers who are unaware of current evidence 2
- Hydroxychloroquine has been extensively studied with over 15 years of safety data showing no increased risk of congenital defects, spontaneous abortions, or fetal death 11
Practical Recommendations
- Continue hydroxychloroquine at your current dose 1, 2
- Start folic acid 0.4-0.8 mg daily now 5
- Discontinue turmeric/curcumin supplements 1, 8
- Take hydroxychloroquine with food or milk to minimize gastrointestinal side effects 3
- Ensure your rheumatologist and obstetrician communicate about your medication plan 1
