New study sheds light on antipsychotic safety during pregnancy and breastfeeding
NCT ID NCT05766007
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed observational study followed 168 pregnant or breastfeeding women with schizophrenia, psychosis, or mania who were already taking long-acting injectable antipsychotics. Researchers measured drug levels in the mother's blood, breastmilk, and the baby's blood to understand how pregnancy affects drug exposure. The goal is to help healthcare providers make informed decisions about using these medications during pregnancy and while breastfeeding.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- long-acting injectable antipsychotics (Risperidone, Paliperidone palmitate, Fluphenazine decanoate, Flupenthixol decanoate, Zuclopenthixol decanoate)
- What this could lead to
- If successful, this study could help doctors better understand how to safely use long-acting antipsychotics in pregnant and breastfeeding women, improving care for both mother and baby.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly test new therapies. Results may not apply to all women or all antipsychotics, and the small sample size limits how much we can conclude.
