Antidepressants During Pregnancy Do Not Appear To Reduce Relapses And Hospitalizations

Continuing to take antidepressants during pregnancy was associated with higher rates of depressive relapses, hospitalizations and self-harming than stopping antidepressants, according to a study in Pharmacoepidemiology and Drug Safety.

“The decision whether to continue antidepressant use for depression during pregnancy requires weighing maternal and child risks and benefits,” stated the authors in their abstract. “Little is known about the effectiveness of antidepressant therapy during pregnancy.”

Led by Harvard School of Public Health researchers, the authors examined Medicaid claims between 2000 and 2007 for 28,493 women with a depression diagnosis who were taking antidepressants within 90 days before their last menstrual period, and then compared the women who stopped taking antidepressants with those who continued on the drugs.

Compared to the women who stopped taking antidepressants, the women who continued on the drugs were twice as likely to have a depression-related hospitalization, and 1.4 times as likely to have a recorded instance of deliberate self-harm. The results largely held even when accounting for other factors such as levels of baseline depression severity.

“Later in pregnancy, the number of women with an inpatient stay with a depression diagnosis was 2077 (8.6%) and 743 (16.9%) for those who discontinued versus continued AD (antidepressant) treatment, respectively; 237 (1.0%) and 91 (2.1%) had two or more inpatient stays,” they wrote. “Among the high-risk subgroup, 305 (15.0%) and 106 (26.2%) of women who discontinued versus continued AD treatment had at least one inpatient stay with a depression diagnosis; 71 (3.5%) and 25 (6.2%) had two or more stays.”

The authors concluded, “Our findings suggest that either antidepressant medications do not reduce the risk of depression relapse in pregnant women, or that administrative data alone could not be used to validly estimate the effectiveness of psychotropic medications during pregnancy.”

  1. So depressed mothers who keep taking the antidepressants during pregnancy, as psychiatrists generally advise, get worse. And newborns of such mothers experience many bad effects.

    But psychiatrists and drug companies think this is just fine.

    These people have no regard for other human beings at all.

    Psychiatrists, just like anyone else, are morally responsible for what they do.

  2. Beggars belief that pharma gets away with producing these poisons and that doctors prescribe them.

    How many studies have to show that they are dangerous before they are banned, and/or are only able to be prescribed (and supplied free of charge) to those unfortunate people already addicted who cannot or dare not come off them?

  3. The study contradicts the results of a higher quality study (a meta analysis of randomized clinical trial results) conducted by the FDA in a broad patient population without offering any suggestion as to why results in pregnant women should differ from those obtained in the population generally.

    As such, the simplest explanation is that this study is wrong. The potential for confounding in a retrospective cohort study of this type is quite high, and I’m not sure why anyone would bother to perform a study of this type when results from randomized clinical trials are available.
