What is the recommended course of action for a 35-year-old female patient taking a Monoamine Oxidase Inhibitor (MAOI) for depression who becomes pregnant?

From the Guidelines

For a 35-year-old pregnant woman on an MAOI for depression, the recommended course of action is to consult with both her psychiatrist and obstetrician immediately to evaluate risks and benefits of continuing treatment, considering a transition to a better-studied antidepressant with more established pregnancy safety profiles, such as an SSRI, after a thorough risk-benefit analysis. When making decisions about antidepressant use during pregnancy, it is crucial to consider the severity of current symptoms, previous mental health history, and patient treatment preferences, as suggested by the American Psychiatric Association and the American College of Obstetricians and Gynecologists 1. The research to date provides reassurance that intrauterine antidepressant exposure does not substantially increase the risk for neurodevelopmental problems, such as ASD and ADHD, and that other risk factors, including having a mother with an indication for antidepressant treatment, appear to be largely responsible for the increased occurrence of these problems 1. Some key points to consider in the management of this patient include:

• The importance of screening for depression in pregnant women, using validated self-report screening measures, such as the Patient Health Questionnaire, the Hospital Anxiety and Depression Scale, and the Edinburgh Postnatal Depression Scale 1.
• A stepped approach to treatment of depression during pregnancy, where women with mild depression are monitored and encouraged to exercise and seek social support, and women with moderate-to-severe depression are offered evidence-based treatment, such as cognitive therapy or antidepressants 1.
• The potential risks and benefits of continuing MAOI treatment during pregnancy, and the possibility of transitioning to a different antidepressant with a more established safety profile, after a careful washout period to avoid serotonin syndrome. Throughout pregnancy, closer monitoring will be needed, including more frequent prenatal visits, mental health assessments, and possibly additional ultrasounds, to balance maternal mental health needs against potential fetal risks, recognizing that untreated severe depression also poses significant risks to both mother and developing baby.

From the Research

Recommended Course of Action for a 35-year-old Female Patient on an MAOI for Depression who Becomes Pregnant

The provided studies do not directly address the use of Monoamine Oxidase Inhibitors (MAOIs) during pregnancy. However, we can discuss the general approach to managing depression during pregnancy and the use of alternative antidepressants.

Managing Depression During Pregnancy

• Untreated depression can have significant risks for both the mother and the fetus, including poor prenatal care, premature birth, and low birth weight 2, 3.
• Non-pharmacologic approaches, such as therapy and lifestyle changes, may be effective for mild to moderate depression 3.
• For moderate to severe depression, antidepressant therapy may be necessary, and Selective Serotonin Reuptake Inhibors (SSRIs) are often considered as a first-line treatment option 4, 2, 3.

Use of SSRIs During Pregnancy

• SSRIs have been associated with an increased risk of certain complications, including low birth weight and small for gestational age 5.
• However, the available evidence suggests that SSRIs can still be considered a relatively safe option for pregnant women who require pharmacological treatment for depression 4, 2, 3.
• The decision to use SSRIs during pregnancy should be made on a case-by-case basis, taking into account the potential benefits and risks, as well as alternative treatment options 2, 3.

MAOIs and Pregnancy

• Unfortunately, there is no direct information available in the provided studies regarding the use of MAOIs during pregnancy.
• In general, MAOIs are not typically considered a first-line treatment option for depression during pregnancy due to the potential risks associated with their use.
• If a patient is already taking an MAOI and becomes pregnant, it is essential to consult with a healthcare provider to discuss the best course of action, which may involve switching to a different antidepressant or adjusting the treatment plan accordingly.
