All antidepressants, including the newer generation of SSRIs, triple the chances of the child developing autism. A study of 1,700 children with autism discovered that even the supposed 'safer' non-selective monoamine reuptake inhibitors were just as likely to cause the problem if the mother took them while she was pregnant.
Women who suffer depression when they are pregnant should seek out non-drug therapies instead, say the researchers.
In a separate study, the anti-epilepsy drug valproate (Epilim) increases the risk of autism "significantly" if it's taken during pregnancy. Autism is the latest in the list of serious effects to the unborn child, including congenital malformation and delayed cognitive development.
