Taking painkillers based on acetaminophen, more commonly known as paracetamol, during pregnancy can negatively affect the child's further development. This is reported by the weekly magazine "Profile".

Research on this topic is presented in the specialized journal "Paediatric and Perinatal Epidemiology". Until recently, acetaminophen was considered safe during pregnancy; the drug was most often taken by pregnant women with mild to moderate pain. But the results of recent studies show that regular intake of paracetamol can affect the development of behavioral disorders such as attention deficit disorder, hyperactivity and autism, which can begin to develop long after taking time.
Scientists at the University of Bristol have found that taking acetaminophen during pregnancy affects the behavior and temperament of the child: in most cases, they are hyperactive. The same conclusions were reached by a group of Spanish researchers who conducted more thorough studies of 2,644 pregnant women 3 years ago. These children had autism spectrum disorder with social retardation, with the worst cases occurring in children whose mothers took pain relievers on a regular basis.
In 2014, a study by a professor at the Institute of Experimental and Clinical Pharmacology and Toxicology at the University of Erlangen was published, which found a link between regular intake of acetaminophen during pregnancy and the risk of developing ADHD and even asthma in a child at a later age.
