When it comes to taking antidepressants in pregnancy, women and their doctors have a difficult decision to make. Depression in pregnancy and following childbirth (the postpartum period) is common and has potentially serious consequences. Suicide is a leading cause of maternal death in the UK. The Conversation

However, a number of studies over the past ten years have reported problems associated with taking antidepressants during pregnancy. These include impacts on the pregnancy, such as early delivery and lower birth weight; increased rates of malformations, such as heart problems in the baby; and an increased risk of autism in children. A paper published in JAMA adds to the evidence. It found that exposure to antidepressants in the womb is associated with a modest increased risk of speech and language disorders.

Listen: what is the best health care for you and your new family?

Based on the types of newspaper headlines that usually accompany these reports, it is likely that pregnant women and their partners will be very concerned. But interpreting these complex studies is difficult. So what do we know, and how should women, partners and their doctors respond?

The first important point is that women should not be taking medication in pregnancy unless it is of benefit. For a woman taking an antidepressant and who is considering starting a family, or finds that she is pregnant, this is an excellent time to consider whether the drugs are still needed.

It is important to consider all treatment options, not just drugs. Talking treatments, particularly for mild to moderate depression, may be a better option for some women. Sadly, access to psychological therapies is still problematic in many areas.

The studies have problems.

Although there are a number of studies now reporting problems, the cause of this relationship remains uncertain. It is possible that the problems are due to the antidepressants, but it may also be due to the effects of the mood disorder for which the drugs have been prescribed.

In a number of studies, depressive symptoms in pregnancy that were not treated with antidepressants were also associated with the same problems. Even if the risk is higher for those on antidepressants, as in the JAMA study, it is possible that it reflects an increased severity of depression in the women taking antidepressants.

It may also be that other factors found more commonly in women prescribed antidepressants account for the increased risk, such as diet, alcohol and drug use, and obesity. Many studies are not able to take these into account because the data is often not available. But reassuringly, perhaps, the more studies that address these factors, the more the risk of taking the pills seems to diminish.

Sometimes pills are the best option

It is important to put the increased risk into perspective. Although it is still difficult to know for definite whether antidepressants cause harm to mother and child, most studies suggest a small to modest increase in risk.

Episodes of depression can range from mild and brief to severe and long lasting. A number of treatment approaches may help pregnant women with depression, ranging from improved support and psychological and social interventions to treatment with antidepressants. The UK’s National Institute for Health and Care Excellence (NICE) recommends antidepressant treatment for people with moderate to severe episodes of depression. For some women with this severity of depression, or with a history of severe mental illness, taking medication in pregnancy may be the best option.

The decision to take medication in pregnancy is always difficult. Antidepressants definitely have their place. Not only is suicide a risk, but if a woman has an episode of depression it can have profound implications for the mother, baby and the whole family. There may be risks with taking antidepressants, as with other drugs, but there are also significant risks from not receiving treatment.
