Seoul: The drug safety regulator said Thursday that pregnant women can take Tylenol after consulting with a doctor in line with existing precautions amid growing concerns following a recent U.S. government announcement linking the pain reliever to an increased risk of autism.

According to Yonhap News Agency, "If a high fever of 38 C or higher persists during early pregnancy, it could affect the fetal nervous system," the Ministry of Food and Drug Safety (MFDS) said in a press release. "If symptoms are severe, acetaminophen-based fever reducers and pain relievers can be taken."

The ministry, however, advised that pregnant women should consult a medical professional before using any medication containing acetaminophen, and that daily intake should not exceed 4,000 milligrams.

"Current domestic approval information for acetaminophen-containing medications, such as Tylenol, does not include any association between use during pregnancy and autism," it added.

The recommendation came after a recent U.S. government announcement that acetaminophen use during pregnancy may heighten the risk of autism in newborns.

The MFDS said it has asked Tylenol-related companies to submit their opinions and data regarding the U.S. government's announcement.

If new scientific evidence is confirmed through review, the findings will be reflected in the precautions and other approval information for acetaminophen-containing products, it added.
