Some Antidepressants May Pose Increased Risk Of Birth Defects

NPR - July 9, 2015

Some antidepressants may increase the risk of birth defects if taken early in pregnancy, while others don't seem to pose the same risks, a study finds.

The question of whether antidepressants can cause birth defects has been debated for years, and studies have been all over the map. That makes it hard for women and their doctors to make decisions on managing depression during pregnancy.

To try to untangle the question, researchers at the Centers for Disease Control and Prevention analyzed federal data on more than 38,000 women who gave birth between 1997 and 2009. They looked at the number of birth defects among babies and asked women whether they took any antidepressants in the month before getting pregnant or during the first three months of pregnancy.

The study, published Wednesday in The BMJ, found no association between the most commonly used antidepressant, sertraline (Zoloft), and birth defects. Forty percent of the women who took antidepressants took sertraline.

They also found no increased risk of birth defects with the antidepressants citalopram (Celexa) and escitalopram (Lexapro).

But the analysis did find an association between birth defects and the antidepressants fluoxetine (Prozac) or paroxetine (Paxil). That included heart defects, abdominal wall defects, and missing brain and skull defects with paroxetine, and heart wall defects and irregular skull shape with fluoxetine. The relative risk increased 2 to 3.5 times, depending on the defect and the medication.

That may sound like a lot, but Jennita Reefhuis, an epidemiologist and lead researcher in the study, says "the overall risk is still small."

The absolute risk in the children of women who were treated with paroxetine early in pregnancy increased the risk of brain and skull malformation (anencephaly) from 2 to 7 per 10,000 births. For one of heart defects, the risk increased from 10 to 24 per 10,000 births.

Since this is an association study, it doesn't prove that the medications caused birth defects.

Many women who are depressed during pregnancy will be depressed after their babies are born.

Pregnant Women With Depression Face Tough Choices, No Easy Answers
"If you're planning to get pregnant, it really is important to talk with your healthcare provider to see if there are options and if you could choose a safer option among antidepressants," Reefhuis says. "Of course, not all antidepressants work the same for everybody, so that's something that women need to consult with their healthcare provider about."

The risks found in this study should be taken in context, says

Dr. Edward McCabe, chief medical officer for the March of Dimes Foundation. "This paper showed that those antidepressants that appeared to be less safe do not show as high a risk of birth defects as some of the earlier reports showed, so that's also reassuring."

Some women may try to wean themselves off antidepressants during pregnancy, some may opt for group or individual talk therapy in the interim and some may switch antidepressants. But any decision, cautions McCabe, should be done in consult with a woman's healthcare provider, adding that women should not suddenly stop taking antidepressant medication altogether.

"That can cause serious risk for the woman, including suicide," he says, "and if she's pregnant, even more risk for the developing fetus than the medication itself."

Stress in the mother can increase problems in pregnancy, McCabe notes, including premature birth and low birth weight. "A woman who is experiencing the stress of an uncontrolled depression may be putting her baby significant risk," says McCabe.

McCabe says he hopes women will understand that "being on an antidepressant should not keep them from having a pregnancy, because they can be put on a drug that's safe for their baby and will control their depression."

Mums-to-be warned of birth defect antidepressants link

Belfast Telegraph, July 9, 2015

By Jennifer Cockerell

Taking certain antidepressants while pregnant has been associated with an increased risk of birth defects.

Researchers in the United States focused on the commonly used selective serotonin reuptake inhibitor (SSRI) antidepressants, which they said are increasingly being used by women of reproductive age and during pregnancy.

They analysed women who took citalopram, escitalopram, fluoxetine (Prozac), paroxetine or sertraline at least once between the month leading up to conception and the third month of pregnancy.

The team said that while they found "reassuring evidence" for some SSRIs, some birth defects were up to three-and-a-half times more likely to occur in babies whose mothers took paroxetine or fluoxetine.

The research analysed 18,000 mothers of infants with birth defects and 10,000 mothers of infants without defects, born between 1997 and 2009.

Dr Michael Bloomfield, a clinical lecturer in psychiatry at University College London, said that doctors in the UK generally prescribe lower doses of psychiatric medicines to patients than in the US and warned that no one should stop taking treatment without talking to their doctor first.

He added: "It has been known that for some time that there is a small increase in the risk of birth defects when women take these medicines in pregnancy.

"Any woman who is either pregnant or planning to become pregnant and needs to take a serotonin reuptake inhibitor should discuss her treatment with her GP or psychiatrist."
