Sedatives in Pregnancy Not Tied to Children’s Mental Health

A large new study offers reassurance to pregnant women who rely on common sedatives for anxiety or insomnia, with implications for how clinicians approach inpatient or outpatient mental health treatment during pregnancy. South Korean researchers found no increased risk of psychiatric or neurodevelopmental disorders, including ADHD and autism, in children whose mothers used benzodiazepines or Z-hypnotics while pregnant.

The finding speaks to a difficult tradeoff in behavioral health on how to treat a parent’s mental health condition without creating new worries about the child.

The Study’s Finding

Researchers used South Korea’s national health database to track nearly 3.8 million children born between 2010 and 2022. They compared children exposed to benzodiazepines or Z-hypnotics during pregnancy with children who weren’t exposed and children whose mothers had used the drugs before but not during pregnancy.

About 2.5% of the children, or 94,482, had exposure during pregnancy. At first glance, psychiatric disorders were slightly more common among exposed children, at 19.2%, compared with 13.8%. But when researchers used a sibling comparison to account for shared family, genetic and environmental factors that impact mental health conditions, the association disappeared, with no increased risk for any individual disorder.

Maternal Mental Health Treatment Matters

Anxiety and insomnia are among the most common conditions during pregnancy, and benzodiazepines and Z-hypnotics are often prescribed to manage them. Leaving a serious mental health condition untreated carries its own risks, like substance abuse, for both parent and child. That’s why access to effective mental health treatment during and after pregnancy is so important.

The authors concluded there’s no substantial evidence that prenatal exposure to these medications raises a child’s risk of psychiatric disorders. Other researchers agreed the findings are reassuring but cautioned that “this does not mean that sedatives should be prescribed without caution.” They urged clinicians to weigh signals around prolonged use and late-pregnancy exposure against the dangers of untreated maternal illness.

Understanding Co-Occurring Conditions

Mental health and substance use are often intertwined. Benzodiazepines, while effective for short-term anxiety and sleep problems, can lead to dependence. In fact, the study’s outcomes even included substance use disorder among the conditions assessed in children. When a mental health condition like anxiety and a substance use concern occur together, it’s known as a co-occurring disorder or dual diagnosis. Integrated treatment that addresses both at once tends to produce better outcomes.

Options for Anxiety and Insomnia

Medication is one tool, but not the only one. Evidence-based therapies can help many people manage anxiety and insomnia, sometimes reducing the need for sedatives.

• Cognitive behavioral therapy (CBT) for anxiety and insomnia
• Medication for substance misuse and management and regular review with prescribers
• Integrated care in rehab for women or mothers for co-occurring mental health and substance use concerns

Mental Health & Dual Diagnosis Treatment

Decisions about medication during pregnancy are personal and should be made with a qualified clinician who knows your history. If you’re looking for support, ask providers whether a program offers dual diagnosis care, and confirm insurance or Medicaid coverage before starting.
