Researchers analyzed data on almost 113,000 children and their parents, including 2,246 kids who were diagnosed with ADHD.
Almost half of the mothers took acetaminophen (also known as paracetamol) at some point during pregnancy, researchers report in Pediatrics.

Some people get caught in the ‘loop phenomenon’, where they ask the same question or do the same action over and over again. The person may shout, scream or become aggressive and suspiciousness is common.
In fact, when women took acetaminophen for less than eight days, they were 10 percent less likely to have kids with ADHD than mothers who didn't use the drug at all during pregnancy, the study found.
Women used the medicine for fever and infections for 22 to 28 days, however, were more than six times more likely to have kids with ADHD than mothers who avoided the drug during pregnancy.'Surprisingly, adjusting for all the medical conditions related to acetaminophen use during pregnancy (e.g., infections and pain) and familial genetic risk for ADHD, children exposed to long-term use of acetaminophen use during pregnancy were more than two times more likely to have ADHD diagnosed by a specialist in a clinic,' said lead study author Eivind Ystrom of the Norwegian Institute of Public Health and the University of Oslo.'This is important, since more than 50 percent of women in western countries use acetaminophen during pregnancy, a large number of children are also exposed to long term use,' Ystrom said by email.
