Antipsychotics — second generation/newer

Milsaperidone

Second-generation or newer antipsychotic

Brand / product examples: Bysanti

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

4 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-038Provisional public source

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-055Evidence gap

Milsaperidone was FDA approved in February 2026 and had no adequate human pregnancy outcome cohort by the evidence cutoff.

not applicable
Effect or numbers carried forward

FDA approval 2026-02-20; DailyMed marketing start 2026-07-01

Limitations

Marketing-start field does not establish broad commercial availability; postmarketing pregnancy denominator is negligible.

A stable patient should not be switched reflexively after conception solely to use a medicine with more pregnancy data.

Formal appraisal

Exposure window
after conception
Comparator
continuing an effective regimen
Effect or numbers carried forward

No single effect estimate; relapse and fetal polypharmacy tradeoff

Limitations

Important exceptions include valproate and compelling toxicity/ineffectiveness; individual history controls the decision.

If an antipsychotic was effective throughout pregnancy, routine postpartum switching solely for lactation is usually discouraged.

Public-source certainty descriptor
guideline recommendation
Formal appraisal

switching to a different agent
Effect or numbers carried forward

No single effect estimate

Limitations

Clozapine, milk-supply goals with aripiprazole, infant prematurity/illness, and long-lived/LAI exposure may change the decision.
