Is Fluoxetine (Prozac) safe during pregnancy?
What the FDA-approved label for Fluoxetine (Prozac) 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 (Pregnancy Category C) states fluoxetine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It notes there are no adequate and well-controlled studies in pregnant women, and that first-trimester epidemiological studies show inconsistent results — more than 10 studies found no increased risk of congenital malformations overall, while one cohort study reported an increased risk of cardiovascular malformations; the label says a causal relationship has not been established. It warns that neonates exposed to SSRIs late in the third trimester have developed complications (respiratory distress, feeding difficulty, jitteriness, and others) requiring prolonged hospitalization, and that SSRI use in pregnancy may be associated with an increased risk of persistent pulmonary hypertension of the newborn (PPHN), though studies are mixed. The label also notes that discontinuing antidepressants in pregnancy raised the risk of depression relapse, and says the decision must be made case by case. This is a decision for the patient and their prescriber — do not start or stop on your own.
Frequently asked questions
Is Fluoxetine safe to take during pregnancy?
The honest answer is uncertainty: the label does not have enough pregnancy data to call Fluoxetine 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 Fluoxetine 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 Fluoxetine 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.
