Schizophrenia typically manifests in individuals aged 20 to 29 and affects both men and women, although it’s more prevalent in females. For women with schizophrenia who are pregnant or planning to conceive, the use of quetiapine—commonly known by the brand name Seroquel—raises significant concerns. These individuals often grapple with the challenge of managing their mental health while ensuring the well-being of their developing baby. Unfortunately, there is insufficient data regarding the safety of quetiapine during pregnancy, making it crucial to consult a healthcare provider about any medical conditions and medications.

Understanding Quetiapine

  • Brand Name: Seroquel
  • Manufacturer: AstraZeneca
  • Primary Use: Quetiapine is primarily prescribed for treating schizophrenia and managing manic episodes linked to bipolar I disorder.
  • Pregnancy Safety Rating: Category C, indicating that risk cannot be ruled out based on available data.
  • Recommendation: Limited human data exists, with animal studies suggesting potential risks.

Side Effects

  • Common (19-10%): Headaches, dizziness, and drowsiness.
  • Occasional (9%-3%): Constipation, orthostatic hypotension, dyspepsia (heartburn, indigestion), tachycardia, rash, rhinitis, dry mouth, and abdominal pain.
  • Rare (2%): Back pain, weight gain, and fever.

Considerations for Pregnancy and Lactation

There is currently no information on whether quetiapine passes into breast milk, so it is generally discouraged for breastfeeding mothers.

According to various expert sources, quetiapine has demonstrated significant effectiveness in alleviating symptoms of schizophrenia. Although it has not shown teratogenic effects in two animal species, the doses tested were low, and higher doses were not assessed due to toxicity concerns. Human data remains too scarce for a conclusive evaluation of risks to the embryo or fetus. The American College of Obstetricians and Gynecologists recommends caution with atypical antipsychotics during pregnancy, advocating for a thorough risk-benefit analysis.

Given that quetiapine is often necessary for managing severe mental illness, the benefits for the mother may outweigh the unknown risks to the fetus. A 1996 review highlighted that women with chronic psychiatric disorders should remain on appropriate medications throughout pregnancy. Additionally, it is often suggested that women taking atypical antipsychotics increase their folic acid intake to mitigate the risk of neural tube defects, as they may be more susceptible due to inadequate folate and obesity.

From the Physicians’ Desk Reference, it is emphasized that quetiapine should only be used during pregnancy if the potential benefits outweigh the risks to the fetus. Meanwhile, the Reprotox Toxicology Center states that animal studies indicate quetiapine is unlikely to heighten the risk of congenital anomalies.

If you’re pregnant and have inquiries about medication usage during this time, consider consulting the Reprotox Toxicology Center, which serves as a valuable resource for medication-related questions.
