Is Prednisone safe during pregnancy?
What the FDA-approved label for Prednisone actually states in its Pregnancy Risk Summary — not a secondhand verdict. The decision is one to make with your prescriber.
What the label’s pregnancy summary says
This is an older-format label that addresses pregnancy in a 'Usage in pregnancy' subsection rather than a structured Section 8.1. The label states that adequate human reproduction studies have not been done with corticosteroids, so use in pregnancy, in nursing mothers, or in women of child-bearing potential requires that the possible benefits of the drug be weighed against the potential hazards to the mother and the embryo or fetus. It adds that infants born to mothers who received substantial corticosteroid doses during pregnancy should be carefully observed for signs of hypoadrenalism. The label does not establish a specific risk and does not tell patients to start or stop the drug on their own; anyone who is or may become pregnant should discuss it with their prescriber.
Frequently asked questions
Is Prednisone safe to take during pregnancy?
The honest answer is uncertainty: the label does not have enough pregnancy data to call Prednisone safe or unsafe (summary above). That is a "decide with your prescriber" situation, weighing your condition against the unknown, not a green or red light. The one universal rule: do not start or stop a medication in pregnancy without medical advice — an untreated condition can carry its own risk to a pregnancy.
What does the FDA label say about Prednisone in pregnancy?
The summary above is transcribed from the label's Pregnancy Risk Summary (§8.1). Since 2015 FDA labels replaced the old A/B/C/D/X letter categories with a narrative that describes what human and animal data actually show, which is what you are reading here — not a single letter grade.
Is Prednisone safe while breastfeeding?
That is a separate question the label answers in a different section (§8.2, Lactation), and it does not always match the pregnancy verdict. This page covers pregnancy only. For breastfeeding, ask your prescriber or pharmacist, or check the NIH LactMed database, which summarizes the drug-in-breast-milk evidence.

The pregnancy information is transcribed from the drug’s FDA-approved label (§8.1) and mirrors what the label states — “insufficient data” is never rounded up to “safe.” This is general reference information, not medical advice. Whether to take any medication in pregnancy is a decision for you and your prescriber; do not start or stop a drug on your own, because an untreated condition can also carry risk.
