Examples of benzodiazepines include lorazepam, clonazepam, and alprazolam. These drugs should only be used with methadone when other drugs don’t work well enough.
Methadone has been detected in amniotic fluid and cord plasma at concentrations proportional to maternal plasma and hinein newborn urine at lower concentrations than corresponding maternal urine.
