Is Ibuprofen (Advil) safe during pregnancy?
What the FDA-approved label for Ibuprofen (Advil) 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
The label names a specific fetal risk: as an NSAID, ibuprofen can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios (low amniotic fluid) and, in some cases, neonatal kidney impairment. Because of this, the label says to limit use between about 20 and 30 weeks of gestation and to avoid it at about 30 weeks and later. For the first and second trimesters, the label calls observational data on other embryofetal risks inconclusive and says the background risk of birth defects/miscarriage for this population is unknown. This is not medical advice for your situation — a pregnant person should consult their prescriber about the label's guidance.
Frequently asked questions
Is Ibuprofen safe to take during pregnancy?
The label flags a real concern for Ibuprofen — see the summary above. This is not a drug to start or continue in pregnancy on your own; it needs a prescriber weighing the specific risks against the reason you would take it. 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 Ibuprofen 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 Ibuprofen 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.
