We are alarmed over recent claims of harm from acetaminophen. As your trusted medication experts, we affirm there has been no new evidence in two decades that the use of acetaminophen in pregnancy causes autism, ADHD, or intellectual disability. The most reputable studies—including one published last year—found no significant associations.
As stated by FDA, at usual doses for treating fever in pregnancy, acetaminophen remains safe and effective. The occurrence of untreated fever in pregnancy has far more serious adverse implications for the fetus. Acetaminophen is the only FDA-approved medication known to be safe and effective at usual doses in people who are pregnant. This has not changed.
While it is appropriate to continuously monitor drug safety signals and review emerging research, claims that are not rooted in science are confusing to patients and health care providers who are caring for and counseling patients during pregnancy.
You rely on us to make recommendations and ensure safety in the use of products to treat minor, self-limiting illnesses with nonprescription drugs, including acetaminophen. Based on the current literature, acetaminophen remains a safe option for people who are pregnant when used appropriately.
