Cardiorespiratory depression and hyperglycemia after unintentional ingestion of brimonidine in a neonate.

PURPOSE: Brimonidine is a third-generation selective alpha-2 adrenergic agonist that lowers intraocular pressure by decreasing aqueous humor production and increasing uveoscleral flow. Its safety profile for children <2 years of age remains unknown.

METHODS

We describe a case of ingestion of a single drop of brimonidine 0.2% in a newborn, resulting in sedation, cardiorespiratory depression, and hyperglycemia within minutes.

CONCLUSIONS

This report adds to the existing evidence that brimonidine can have serious adverse side effects and should therefore be used with extreme caution in infants <2 years of age. Additionally,safety procedures like double-checking should also include vitamins or oral supplements to improve medication safety in the neonatal intensive care unit.
