To identify and quantify adverse events (AEs) associated with alpha-2 adrenergic agonists prescribed for the treatment of glaucoma in infants. We queried the Federal Adverse Event Reporting System (FAERS) from 2004-2023Q1 for AE reports related to brimonidine use in patients aged 12 months or younger. We then conducted a disproportionality analysis using data mining algorithms, including the reporting odds ratio, proportional reporting ratio, empirical bayes geometric mean, and information component to identify significant symptoms. We identified 35 unique AE reports associated with brimonidine. Of these, 27 cases involved hospitalization, 13 cases involved life-threatening complications, 18 cases reported other complications, and 1 case involved a congenital anomaly. The most commonly reported AE was hypotonia, occurring in 20 cases. This was followed by other systemic symptoms, including hypothermia, depressed level of consciousness, lethargy, general toxicity, and pallor, among others. All symptoms were found to be significant in the disproportionality analysis. Notably, most cases were not known to involve an ophthalmic route of exposure. The use of alpha-2 adrenergic agonists in infants aged 1 year or younger has been associated with various systemic AEs, including hypotension, respiratory depression, and central nervous system depression. Ophthalmologists should be aware of these potential risks. Further, more rigorous warnings should be in place to prevent unintentional exposure of infants to brimonidine.
