In utero drug exposure and hearing impairment in 2-year-old children A case-control study using the EFEMERIS database

This is the first study evaluating the risk of hearing disorders due to in utero exposure to drugs. Hearing loss was associated with valproic acid and low-dose acetylsalicylic acid exposure during pregnancy. Conversely, children with normal hearing were more likely to have been exposed in utero to corticosteroids than children with hearing loss.
