A new study out yesterday—June 1, 2010—has revealed a higher rate of miscarriages in women who were taking antidepressants during pregnancy. How much higher? Sixty-eight percent—yes —that’s 68%—higher. Frankly, that is nothing short of shocking.

Published in the Canadian Medical Association Journal, the study was done in Canada through the University of Montreal. FYI—This was no small study either—the investigators used data from 5,124 women who are part of a large, population-based study of pregnant women who had clinically verified miscarriages, and a large sample of women from the same registry who did not have a miscarriage. Among the women who miscarried, 284 or 5.5 percent, had taken antidepressants during their pregnancy.

In fact the findings are so robust that the physicians who did the study are suggesting that this is a class effect—in other words the effect could be attributed to all selective serotonin reuptake inhibitors—or SSRIs. Here’s what’s being reported in the press:

“These results, which suggest an overall class effect of selective serotonin reuptake inhibitors, are highly robust given the large number of users studied,” the study’s senior author, Dr. Anick Berard, said in a statement. (UPI.com)

The antidepressants that showed a particular association with miscarriage in the study were paroxetine (trade names: Seroxat and Paxil) and venlafaxine (trade names: Effexor, Efexor, Alventa, Argofan, Trevilor). The investigators also found that the risk of miscarriage doubled with a combination of different antidepressants.

Just for the record, the antidepressants “investigated” in the University of Montreal study are serotonin reuptake inhibitors (citalopram, fluoxetine, fluvoxa-mine, paroxetine and sertraline); tricyclic antidepressants (ami-triptyline, clomipramine, desipramine, doxepin, imipramine, nortriptyline, trimipramine), serotonin– norepinephrine reuptake inhibitors (venlafaxine) and “other antidepressants” (serotonin modulators, monoamine oxidase inhibitors, tetracyclic piperazino-azepines, and dopamine and norepinephrine reuptake inhibitors).

This study is just the latest to show an association between, well, for lack of a better term let’s say “serious adverse events” and SSRIs and SNRIs in particular.

New Study—Taking Antidepressants While Pregnant More Than Doubles Risk of Miscarriage

Taking antidepressants during pregnancy increases the risk of spontaneous abortions by about two-thirds, Canadian researchers reported Monday. The increased risk was greatest with the family of drugs known as selective serotonin reuptake inhibitors (SSRIs), especially paroxetine and venlafaxine, and when more than one family of drugs were used.

Depression in women is most common during the child-bearing years, and estimates suggest that as many as 15% of pregnant women suffer from it. Because of fears about the effects of drugs, particularly psychiatric drugs, during pregnancy, only about 3.7% of women use them during the first trimester. Most studies looking at the use of antidepressants during pregnancy have focused on their effects on the fetus. Small studies of their effects on abortion have produced inconsistent results. Expecting mothers cannot routinely stop using the drugs, however, because that also presents risks to both the mother and the fetus.

Producing a controlled clinical trial examining the effects of the drugs is virtually impossible because few women would be willing to participate, experts said. The only way to get at the data is to examine it retrospectively.

In the new study, Dr. Anick Berard, director of the University of Montreal’s Research Unit on Medications and Pregnancy at University Hospital Center Sainte-Justine used information from the Quebec Pregnancy Registry to identify 5,124 women who had a spontaneous abortions between 1998 and 2003 — before warnings about the risks of the drugs became more common — and compared them with about 10 times that many carefully matched women who did not have abortions. A separate database provided information about prescriptions the women had filled.
