Background/aim: Acetaminophen is frequently used as an analgesic during pregnancy. The purpose of the present study was to evaluate the effects of acetaminophen administered to pregnant mice on the fetal brain, attention, memory, and learning functions in the postnatal period, and genetic mechanisms in these mice. Materials and methods: The study was designed with two different groups. The first group consisted of pregnant mice that were injected with acetaminophen, while the second group was comprised of pregnant mice that were injected with saline. 1st, 2nd, and 3rd days of pregnancy, one of the mice was injected subcutaneously with 100 mg/kg acetaminophen, and the other mouse was injected subcutaneously with 0.9% saline. On the 21st day after birth, five female and five male mice were randomly selected for the experimental and control groups. Behavioral tests were performed on mice at 2 months of age. In addition, changes in the transcript levels of 93 genes were evaluated by Real-Time PCR in the hippocampus. Results: The control group showed more interest in the new object than the acetaminophen group (p=0.002). In the marble burying test, greater burying activity was observed in the control group than in the acetaminophen group (p=0.0345). No significant difference was observed between the control and acetaminophen groups in the social interaction and tail suspension tests. GABRG3, GRM3, PICK1, CEBPB, and EGR4 mRNA expression levels increased in the acetaminophen group (0.0317, 0.0159, 0.0069, 0.0457, 0.015, p value respectively). Conclusions: Prenatal acetaminophen exposure affected both behavioral tests and transcript levels. Therefore, the potential effects of prenatal acetaminophen exposure should be carefully investigated.
