Antipsychotics — second generation/newer

Aripiprazole

Second-generation or newer antipsychotic

Not a categorical safety rating

This record organizes questions; it does not close them.

The clinical fields and position statements are prepopulated from the public-source corpus. They have not completed individual dual extraction, formal appraisal, exact-label reconciliation, or multidisciplinary sign-off. Do not use this page to justify abrupt discontinuation or reflexive switching.

Decision taxonomy

Five positions kept separate

These are workbench statements for reviewer execution. They are not independently commissioned, patient-specific recommendations.

  1. 01

    Stable continuation

    Workbench statement

    Do not withhold or discontinue solely because of pregnancy or lactation. For this record, assess indication, prior response, relapse severity, dose/formulation, alternatives, exposure timing, and mapped evidence; individual commissioned adjudication remains pending.

  2. 02

    New initiation in pregnancy

    Workbench statement

    For a new start, prefer an effective option with the strongest diagnosis-specific efficacy and reproductive evidence when clinically suitable. This record has not received an individual, independently verified initiation ranking.

  3. 03

    Switch before conception

    Workbench statement

    Before conception, consider a switch only when expected benefit exceeds relapse, withdrawal, failed-switch, and dual-exposure risks. Build and monitor the plan before pregnancy when feasible; no universal switch direction is assigned here.

  4. 04

    Unplanned exposure

    Workbench statement

    After unplanned exposure, confirm product, route, dose, timing, indication, co-exposures, and symptoms; do not advise abrupt cessation. Use the mapped evidence and current label to decide whether any targeted fetal assessment is indicated.

  5. 05

    Delivery, postpartum & lactation

    Workbench statement

    Create separate delivery, postpartum-dose, neonatal-observation, and lactation plans. Do not infer breastfeeding suitability from pregnancy evidence or routinely taper before delivery without drug-specific support.

Linked evidence

8 mapped claim summaries

Mapping can include class-wide, framework, formulation, regulatory, or evidence-gap claims. A linked claim is not necessarily a drug-specific causal estimate.

B-033Provisional public source

Large adjusted cohorts do not show a meaningful overall increase in major congenital malformations for antipsychotics as a class.

Public-source certainty descriptor
moderate—large adjusted cohorts
Formal appraisal
Not started — full text and independent appraisal pending
Exposure window
first trimester
Comparator
no antipsychotic exposure
Effect or numbers carried forward

Huybrechts: atypical adjusted RR 1.05 (95% CI 0.96–1.16); typical adjusted RR 0.90 (0.62–1.31)

Limitations

Contextual class evidence only; do not treat the class point estimates as drug-, route-, fixed-combination-, emergency-formulation-, or LAI-specific estimates. Class averages can hide rare drug-specific effects; confounding, live-birth selection, and exposure misclassification remain.

Neonatal EPS or withdrawal/adaptation signs have been reported after third-trimester antipsychotic exposure.

Public-source certainty descriptor
regulatory class warning; absolute risk unknown
Formal appraisal
Not started — full text and independent appraisal pending
Exposure window
third trimester/near delivery
Comparator
no late antipsychotic exposure
Effect or numbers carried forward

Reported signs include agitation, hypertonia or hypotonia, tremor, somnolence, respiratory distress, and feeding disorder; severity and duration vary, and no reliable incidence is available.

Limitations

Spontaneous reports, co-medications, illness severity, and no reliable denominator; Cobenfy is mechanistically distinct and excluded from this class claim.

B-039Provisional public source

In two large US claims cohorts, the apparent association between second-half-pregnancy antipsychotic exposure and childhood neurodevelopmental disorders attenuated substantially after confounding adjustment; individual-drug analyses were limited to haloperidol, risperidone, olanzapine, quetiapine, and aripiprazole.

Public-source certainty descriptor
Moderate for attenuation of the class association; low for individual drugs and not transferable to unstudied molecules or formulations.
Formal appraisal
Not started — full text and independent appraisal pending
Exposure window
pregnancy exposure with childhood follow-up
Comparator
unexposed children
Effect or numbers carried forward

Any NDD: unadjusted HR 1.91 (95% CI 1.79–2.03) and adjusted HR 1.08 (1.01–1.17); aripiprazole adjusted HR 1.36 (1.14–1.63) was a possible signal requiring replication, not causal proof.

Limitations

Claims exposure, residual confounding, incomplete adherence, live-birth/follow-up selection, and limited individual-drug power; the data window predates multiple inventory agents and did not establish route- or LAI-specific effects.
