Pregnant moms who reach for a bottle of Tylenol after a fever spikes or a headache hits can breathe a little easier. Both the American College of Emergency Physicians (ACEP) and the American College of Obstetricians and Gynecologists (ACOG) have come out strong, saying acetaminophen remains the safest first‑line treatment for pain and fever during pregnancy.
ACEP’s statement reads like a reassurance memo to every emergency department across the country. It stresses that fever and acute pain aren’t just uncomfortable—they can be dangerous for a developing fetus if left unchecked. The group points to a raft of studies that, taken together, show no credible safety signal for acetaminophen when used at recommended doses.
ACOG echoes the same sentiment, noting that the drug is “one of the few options available to pregnant patients to treat pain and fever.” In plain terms, the alternatives—aspirin, ibuprofen, naproxen—carry known risks such as bleeding complications, premature closure of the fetal ductus arteriosus, or impaired kidney function in the baby.
Both societies emphasize one key principle: a risk‑benefit calculation. Untreated high fever, for example, has been linked to neural tube defects and other birth anomalies. Inadequate pain control can stress a mother’s cardiovascular system, indirectly affecting fetal oxygenation. So the calculus often tips in favor of a short, well‑dosed course of acetaminophen.
Doctors are being urged to discuss dosing limits clearly—generally no more than 3,000 mg per day for pregnant patients, unless a specialist says otherwise. They’re also reminded to ask about other sources of acetaminophen, such as cold medicines, to avoid accidental overdose.
On September 22, 2025, the FDA released a notice that sparked headlines: some studies have found an association between prenatal acetaminophen exposure and neurodevelopmental conditions like autism spectrum disorder and ADHD. The agency was careful to add that association does not equal causation, and that many rigorous studies have found no link at all.
In response, ACOG highlighted that fever and pain themselves are harmful, and that withholding an effective treatment could increase maternal and fetal morbidity. They also pointed out that the “contrary studies” the FDA mentioned are methodologically stronger—large sample sizes, better control for confounding variables, and prospective designs.
Practically, the FDA’s notice serves as a reminder for clinicians to counsel patients on moderation. It does not call for a blanket ban, nor does it advise doctors to avoid acetaminophen altogether. Instead, it asks for informed consent: explain the current state of the evidence, acknowledge that research is ongoing, and emphasize the importance of using the lowest effective dose for the shortest necessary time.
For expectant mothers, the takeaway is straightforward. If you have a fever over 101 °F (38.3 °C) or a persistent headache, a doctor‑approved dose of acetaminophen is still the best first step. Keep a log of how much you take, avoid combining it with other over‑the‑counter meds that contain the same ingredient, and talk to your prenatal care provider if you’re unsure.
While scientists continue to explore the nuanced relationship between prenatal drug exposure and child development, the prevailing medical consensus remains: the benefits of properly used acetaminophen far outweigh the theoretical risks. This balanced view helps cut through the noise of sensational headlines and gives pregnant women the clear, evidence‑based guidance they need.
