Neonatal Opioid Withdrawal Syndrome (NOWS) is a condition in which infants undergo withdrawal after exposure to opioids in utero. The current standard of care uses oral morphine and/or methadone which can lead to harmful side effects in the infant. We propose a non-drug based, adjunct treatment that stimulates nerves around the ear, and may help reduce withdrawal symptoms while using less morphine.
