Is Brimonidine safe while breastfeeding?

Summary of use during breastfeeding

Limited information indicates that maternal use of brimonidine 0.2% ophthalmic drops do not adversely affect their nursing infants. However, some authors and the manufacturer warn of possible CNS depression, apnea, lethargy, bradycardia with brimonidine and recommend against its use during breastfeeding.[1-3] To substantially diminish the amount of drug that reaches the breastmilk after using eye drops, place pressure over the tear duct by the corner of the eye for 1 minute or more, then remove the excess solution with an absorbent tissue. The manufacturer of Combigan states that it is not recommended for use during lactation, but there is no evidence for this statement.

Topical brimonidine gel used to treat rosacea has not been studied during breastfeeding. It is unlikely that the topical gel would affect the breastfed infant, but the manufacturer states that it should not be used during nursing. Until more data are available, an alternative topical agent might be preferred

Effects on the breastfed infant

A woman used brimonidine 0.2%, timolol gel-forming solution 0.5%, dipivefrin 0.2%, and dorzolamide 0.5% drops for glaucoma while nursing a newborn. The frequency of medication use, and extent of nursing were not stated. All medications were given immediately after nursing with punctal occlusion of the tear duct. The infant's vital signs were closely monitored with no signs of bradycardia or apnea.[4]

A woman was using ophthalmic drops containing 0.5% timolol and 0.2% brimonidine twice daily in the right eye for 6 months. During this time, she breastfed her infant (extent not stated) apparently without harm to her infant.[5]
