An unusual cause for neonatal abstinence syndrome.

Neonatal abstinence syndrome (NAS) secondary to maternal drug use is a well-recognized clinical entity. We present a novel case of moderately severe NAS in a term infant whose mother was self-medicating with kratom tea. The baby required oral morphine for NAS. After 12 days in neonatal intensive care unit, she was discharged on oral morphine which was discontinued after 2 months. Kratom, a psychoactive herb with opioid activity, has traditionally been used as a stimulant to boost energy, cure cough, depression, pain, sickness and a substitute for opium. Although well known in South East Asia and Africa, this drug is less familiar to physicians in North America. It is undetectable by standard urine drug screening and is being sold as a legal herbal remedy. This is the first report of a newborn developing significant NAS after maternal use of kratom tea. We believe physicians should be aware of this 'new' risk to newborns.
