Phenergan may also cause respiratory depression in newborn babies.

When the mother nurses her baby when under Phenergan, the baby will access the drug via milk and exhibit symptoms such as sleepiness and lack of energy. These symptoms are best reported to a health care provider at early stages to prevent further complications. Additionally, promethazine interferes with the lactation process leading to the production of little milk. Specialists should be contacted in such instances.

Neonatal respiratory depressions and universal respiratory depression from the mother

It is essential that the mother takes more cation when they are about to deliver, to avoid cases of respiratory depression and other childbirth complications. Respiratory depression is described when a fully developed breathing system experiences troubles in the function of gaseous exchange. Most infants require resuscitation when delivered by mothers who took Phenergan during their gestation period.

Blood loss

Phenergan’s also cause possible lack of platelet aggregation, which causes excessive bleeding since clots are inhibited from forming. This condition of the newborns is referred to as thrombocytopenia. Newborns with this disorder are put in the ICU for the transfusion of other active platelet sets in the attempt of reducing the severe bleeding.
