What are the recommendations for managing Vraylar (cariprazine) during pregnancy in a patient already taking methylphenidate?

Discontinue Vraylar (Cariprazine) During Pregnancy

You should strongly recommend discontinuing Vraylar during pregnancy due to insufficient safety data and FDA warnings about neonatal extrapyramidal and withdrawal symptoms, while continuing methylphenidate is reasonable with appropriate monitoring. 1

Vraylar (Cariprazine) in Pregnancy: Critical Concerns

FDA Labeling Warnings

• The FDA label explicitly warns that third trimester use of Vraylar may cause extrapyramidal and/or withdrawal symptoms in neonates, requiring patients to notify healthcare providers of known or suspected pregnancy 1
• There is no established safety profile for cariprazine in pregnancy from controlled studies or systematic data 1

Extremely Limited Evidence Base

• Only one single case report exists documenting cariprazine use throughout pregnancy, which showed no adverse effects but provides insufficient evidence for safety recommendations 2
• This single case cannot establish safety or guide clinical practice given the lack of systematic data on congenital malformations, obstetrical outcomes, or long-term neurodevelopmental effects 2

Risk-Benefit Analysis Strongly Favors Discontinuation

• Unlike conditions requiring continuous antipsychotic coverage (e.g., active schizophrenia with high relapse risk), your patient's clinical context suggests cariprazine may be for mood stabilization in a stable patient 1
• The unknown teratogenic risk combined with documented neonatal complications makes continuation unjustifiable without compelling psychiatric necessity 1

Methylphenidate in Pregnancy: Supportable Continuation

Strong Safety Evidence

• 2024 ACOG guidelines explicitly support continuing methylphenidate if required for daily functioning, as documented risks are very low 3, 4
• Large, well-controlled studies demonstrate no increased risk for major congenital malformations with methylphenidate 4
• Recent comprehensive data show no increased neurodevelopmental risks, including psychiatric disorders, vision/hearing impairments, epilepsy, or growth impairment 4

Documented Minimal Risks

• Possible small increased risk of preeclampsia (not consistently found across studies) 4
• Possible small increased risk of preterm birth, particularly with continued use in second half of pregnancy 4
• Any cardiac malformation risk is only 1.7% and not consistently replicated 4

Management Strategy for Methylphenidate

• Continue at current effective dose or consider dose reduction to lowest effective level 3
• Consider intermittent use on as-needed basis to maximize functioning while reducing fetal exposure 3
• Enhanced monitoring should include fetal echocardiography and blood pressure surveillance for preeclampsia 4

Clinical Action Plan

Immediate Steps

1. Discontinue Vraylar through shared decision-making discussion emphasizing lack of safety data and FDA neonatal warnings 1
2. Continue methylphenidate at current or reduced dose based on functional needs 3, 4
3. Assess psychiatric stability and need for alternative mood stabilization if Vraylar was treating bipolar disorder or psychotic symptoms 1

Alternative Psychiatric Management

• If mood stabilization is needed, consider agents with established pregnancy safety profiles rather than continuing an antipsychotic with no safety data 1
• If antipsychotic coverage is absolutely necessary for severe psychiatric illness, consider agents with more robust pregnancy data (though this would require separate risk-benefit analysis) 1

Monitoring Throughout Pregnancy

• Blood pressure checks at each prenatal visit for preeclampsia surveillance 4
• Fetal growth monitoring given possible associations with methylphenidate 4
• Fetal echocardiography to assess for cardiac malformations 4
• Ensure appropriate maternal weight gain 3

Critical Pitfalls to Avoid

• Do not continue Vraylar based on the single case report - this provides insufficient evidence for safety recommendations 2
• Do not switch methylphenidate to modafinil - modafinil has documented higher rates of major congenital anomalies per 2018 registry data 4
• Do not attribute all adverse outcomes to medication - confounding by indication means underlying ADHD itself may contribute to risks 3, 4
• Do not abruptly discontinue methylphenidate without assessing functional impact - poor maternal functioning can compromise prenatal care and maternal-fetal wellbeing 3

Breastfeeding Considerations for Future Planning

• Methylphenidate is safe during breastfeeding with relative infant doses <1%, generally undetectable in infant blood, and no reported adverse effects 5
• No data exist for cariprazine during breastfeeding, making this another reason to avoid continuing this medication 1
