When it comes to pregnancy, one of the most important decisions parents expect to make is how to ensure both their health and that of their baby. This becomes even more complicated for those who require medication for mental health conditions. Mental disorders such as depression and anxiety are quite common during pregnancy and psychotropic drugs (those used to treat these conditions) are often prescribed. But how safe are these drugs during pregnancy?
Recent research provides some answers, although the picture is not entirely clear.
Why mental health matters during pregnancy
About 15% of pregnant people experience some form of mental disorder during pregnancy. Addressing these conditions is important, not only for the individual’s well-being but also for the baby’s. Untreated mental health problems can lead to negative outcomes such as premature birth or developmental problems for the baby. However, medications used to manage mental health disorders—such as antidepressants, mood stabilizers, and antipsychotics—come with their own concerns.
Doctors and researchers have struggled to weigh the risks and benefits of continuing or starting psychotropic medications during pregnancy. To address this, a recent umbrella review—a study that brings together findings from several smaller studies—was conducted to examine the safety of these drugs during pregnancy. The findings give us more insight into what risks may exist and how strong the evidence is for those risks.
What the study looked at
The review looked at 21 different studies involving more than 17 million participants. It focused on the connection between psychotropic drugs taken during pregnancy and various potential health problems for both the pregnant woman and the baby.
The review evaluated different types of psychotropic drugs, including:
- Antidepressantssuch as selective serotonin reuptake inhibitors (SSRIs)
- Mood stabilizerssuch as lithium
- Antipsychotics
The researchers classified the strength of the evidence into four levels:
- persuasive evidence: Powerful and reliable
- Strongly suggestive evidence: Still strong but with some uncertainty
- Indicative data: Some evidence, however, requires more study
- Weak elements: Small studies with minimal impact
Key findings
One of the highlights of the study was that there is no conclusive or highly suggestive evidence that psychotropic drugs cause major health risks during pregnancy. However, there are some risks that are supported by suggestive evidence.
Here’s what the survey found:
Antidepressants:
- Premature birth: There is some evidence that taking antidepressants during any trimester could increase the risk of preterm birth. For those with depression, the odds of preterm birth were found to be slightly higher.
- Small for gestational age: Refers to babies who are smaller than normal for gestational age. Those taking SSRIs during any trimester had a higher risk for this outcome.
- Congenital malformations: Taking certain antidepressants, especially paroxetine, during the first trimester could increase the risk of birth defects, including heart defects.
Mood stabilizers (lithium):
- Congenital and cardiac malformations: Lithium, used to treat bipolar disorder, has been associated with a higher risk of birth defects, particularly when taken in the first trimester. However, the evidence is considered weak and further study is needed.
- Premature birth: Lithium use was also associated with a higher chance of preterm birth.
Antipsychotics:
- Neuromotor deficits: Antipsychotics have been weakly linked to neuromotor problems, meaning possible problems with coordination and muscle control in the baby.
What does this mean for you?
It is important to remember that while there are some risks, they are relatively small. For example, antidepressants slightly increase the chances of preterm or small-for-gestational-age babies. However, these are not huge risks compared to the consequences of untreated mental health disorders. In fact, stopping medication can lead to a worsening of mental health symptoms, which can have its own negative effects on both parent and baby.
The decision about whether to continue or start psychotropic medication during pregnancy should always be made with your health care provider. Each case is unique and the potential benefits of medication may far outweigh the risks, especially if the mental health condition is severe.
What should you do if you are pregnant and taking psychotropic medication?
If you are pregnant and taking medication for a mental health condition, it is important to have an open and honest discussion with your doctor. Here are some questions you can ask:
- What are the specific risks of my medication for my baby?
- Are there alternative treatments available that may have fewer risks?
- What if I stop taking my medication during pregnancy?
- How can we monitor the baby’s health if I continue the medication?
Your health care team can help you weigh the pros and cons based on your individual situation and make a plan that keeps both you and your baby healthy.
Managing mental health during pregnancy is complex. The good news is that many medications, including antidepressants, can be used safely with minimal risk to the baby. While there are some potential risks, they must be balanced against the risks of untreated mental health conditions. Always consult your doctor to determine the best course of action for your pregnancy.
