Prednisone is sometimes necessary in pregnancy for autoimmune diseases, asthma exacerbations, and other inflammatory conditions. Is prednisone safe in pregnancy requires balancing maternal benefit against fetal considerations. Always work with your OB/GYN.
Pregnancy considerations
- Most prednisone (about 90%) is metabolized by placenta — limited fetal exposure
- Possible association with cleft palate with first-trimester high-dose use (small absolute risk)
- Long-term high-dose can cause fetal growth restriction, preterm birth
- Generally acceptable for short courses or when truly needed
Common pregnancy uses
- Asthma exacerbations
- Autoimmune disease flares (lupus, RA, IBD)
- Severe allergic reactions
- Hyperemesis gravidarum (severe morning sickness)
Prednisone in breastfeeding
Compatible with breastfeeding. Standard doses don’t significantly affect infants.
