Oral steroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus, with special caution during the first trimester due to an increased risk of orofacial clefts and other fetal complications.[1-7]
Systemic corticosteroids like prednisone and triamcinolone are associated with fetal risks such as orofacial clefts, intrauterine growth restriction, and decreased birth weight, particularly when used during the first trimester.[1-3]
Infants born to mothers who have received substantial doses of corticosteroids during pregnancy should be monitored for signs of hypoadrenalism.[1-3]
Topical use of potent corticosteroids during pregnancy, especially in the third trimester and in large amounts, is linked to a significantly increased risk of low birth weight.[2]
The use of short-acting corticosteroids like prednisone, prednisolone, and methylprednisolone, which are more efficiently metabolized by the placenta, may result in lower fetal exposure compared to longer-acting corticosteroids.[8]
Budesonide, due to its high first-pass metabolism, may be preferred for the treatment of mild to moderate disease during pregnancy because of low corticosteroid exposure to the fetus.[8]
