Deciding whether to use antidepressants during pregnancy is a deeply personal and often complex decision. Expectant parents frequently weigh concerns about medication exposure against the realities of managing mental health conditions. Informed discussions with healthcare providers are paramount to navigate these considerations and arrive at a treatment plan that supports both the birthing parent and the developing baby.
Weighing the Considerations: Untreated Mental Health vs. Medication Exposure
Untreated or inadequately managed mental health conditions during pregnancy, such as severe depression, anxiety, or bipolar disorder, can pose considerable risks for both the birthing parent and the developing fetus. For the birthing parent, these risks can include poor prenatal care adherence, unhealthy behaviors, and a higher likelihood of developing postpartum depression or experiencing suicidal ideation. Untreated maternal depression has been linked to increased hospital admissions and complications like preeclampsia.
The effects of untreated mental health on the fetus can be significant, potentially leading to preterm birth, low birth weight, or intrauterine growth restriction. Untreated maternal depression can affect childhood development, potentially leading to higher impulsivity, maladaptive social interactions, and cognitive, behavioral, and emotional difficulties.
Conversely, antidepressant exposure during pregnancy also carries potential risks for the fetus and newborn, though these are considered low. One of the main concerns is neonatal adaptation syndrome (NAS), which can present as temporary withdrawal symptoms in the newborn after birth. These symptoms, occurring in about 25% to 30% of infants exposed to selective serotonin reuptake inhibitors (SSRIs) in late pregnancy, involve jitteriness, irritability, increased muscle tone, and rapid breathing, resolving within a few days to a few weeks.
There is an increased risk of persistent pulmonary hypertension of the newborn (PPHN) with late-pregnancy SSRI exposure, a rare but serious condition where the baby’s lungs do not inflate well. Earlier studies suggested a minor potential for certain congenital anomalies, such as cardiac malformations, with first-trimester antidepressant use, but more recent studies do not support a significant link. The overall risk of birth defects from antidepressant exposure is very low.
Antidepressant Classes and Their Pregnancy Profiles
Different classes of antidepressants have varying safety profiles during pregnancy. Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed and studied for use in pregnancy. Examples include citalopram, sertraline, escitalopram, and fluoxetine. Sertraline and citalopram are often preferred due to extensive safety data and typically low side effects.
One SSRI, paroxetine, has been associated with an increased risk of heart defects in babies when used in the first trimester, leading many healthcare professionals to recommend avoiding it during pregnancy. Serotonin and norepinephrine reuptake inhibitors (SNRIs), such as duloxetine and venlafaxine, can be treatment options, though they may be linked to an increased risk of high blood pressure in the pregnant individual.
Tricyclic antidepressants (TCAs), like nortriptyline and amitriptyline, are older medications. They are not a first-line choice during pregnancy but may be considered if other medications have not been effective. Some TCAs, like clomipramine, may be linked to birth defects. Monoamine oxidase inhibitors (MAOIs) are avoided during pregnancy due to less safety data and higher risks. The older FDA pregnancy categories (A, B, C, D, X) are largely outdated; current medical practice emphasizes a more comprehensive risk-benefit assessment.
Collaborating with Your Healthcare Team During Pregnancy
Managing antidepressant use during pregnancy requires a collaborative approach involving healthcare professionals. An obstetrician, psychiatrist, and other mental health specialists should work together to create an individualized treatment plan. This team approach ensures comprehensive care, addressing both mental health and fetal development.
Regular monitoring of the birthing parent’s mental health and the baby’s development is a standard practice. Adjustments to medication dosage or type may be necessary as pregnancy progresses. For instance, if a birthing parent is stable on an antidepressant that works well, continuing that medication at the lowest effective dose is preferred over switching to a new one, as switching carries risks of relapse and exposure to additional medications.
Combining antidepressant medication with psychotherapy, such as cognitive behavioral therapy (CBT) or interpersonal therapy (IPT), is recommended. Psychotherapy can be a primary treatment for mild depression or a complement to medication for more severe conditions. Abruptly stopping antidepressants without medical supervision is not advised, as this can lead to a return of depressive symptoms or withdrawal effects.
Post-Birth and Breastfeeding Considerations
After birth, infants exposed to antidepressants in utero may experience neonatal adaptation syndrome (NAS), also known as temporary withdrawal symptoms. Infants are monitored for these signs and managed as needed.
Continuing or adjusting antidepressants postpartum is considered, especially given the risk of postpartum depression, which affects about 1 in 7 new mothers. For those with a history of depression, continuing antidepressant therapy during pregnancy may reduce the rate of postpartum depressive episodes. Psychotherapy, sometimes combined with medication, is a primary treatment for postpartum depression.
Many common antidepressants are considered safe for use during breastfeeding, with minimal amounts in breast milk. Sertraline is often chosen for breastfeeding individuals due to its low presence in breast milk and minimal infant side effects. Paroxetine and nortriptyline are also considered safe during breastfeeding. While some medications may cause mild side effects like drowsiness or irritability in the infant, significant complications are uncommon. Individual consultation with a healthcare provider is recommended to discuss the risks and benefits of continuing medication while breastfeeding.
