Substance-use disorder — opioid

Lofexidine

Medication for opioid use disorder, withdrawal, or overdose rescue

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

1 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.

C-011Provisional public source

Lofexidine is an alpha-2 agonist for opioid-withdrawal symptoms, not maintenance treatment; pregnancy evidence is very sparse and withdrawal management should not replace methadone or buprenorphine treatment for OUD.
