Animal data
In animal studies, brimonidine crossed the placenta and entered into fetal circulation to a limited extent; this drug should be used during pregnancy only if potential benefit justifies potential risk to fetus
This drug was not teratogenic when given at oral doses up to 2.5 mg/kg/day in pregnant rats during gestation days 6 through 15 and 5 mg/kg/day in pregnant rabbits during gestation days 6 through 18
Lactation
Not known whether brimonidine tartrate is excreted in human milk, although in animal studies, brimonidine tartrate has been shown to be excreted in breast milk
Because of potential for serious adverse reactions from topical gel in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother
