根據 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5095568/
| FDA category | Comments during pregnancy | |
| cyclosporine | C | Low risk |
| dexamethasone | C | Probably low risk, avoid during first trimester (potential risk of oral clefts) |
| mesalamine | B | Low risk: Limited data for olsalazine; if using sulfasalazine, folic acid supplementation is mandatory |
