Summary

This trial will compare the effect of two different weaning methods on the number of days of opioid treatment for infants with NOWS.

Who is the study for?
This trial is for newborns with Neonatal Opioid Withdrawal Syndrome (NOWS) who are at least 36 weeks gestational age, can take oral feeds and medications, and are receiving morphine or methadone. Hospitals must treat an average of 12 opioid-exposed infants yearly. Infants with seizures not due to NOWS, needing significant respiratory support, already weaning off opioids, having major surgery or defects, or planned discharge on opioids cannot participate.
What is being tested?
The study aims to compare two methods of reducing opioid treatment in infants with NOWS: a rapid wean versus a slow-wean approach. It measures the time from starting to reduce the dose until stopping it completely using either morphine or methadone as primary treatments.
What are the potential side effects?
Possible side effects include symptoms related to withdrawal management such as irritability, sleep disturbances, feeding difficulties and potential respiratory issues. The specific side effects will depend on whether morphine or methadone is used.
