Drug Levels and Effects

Summary of Use during Lactation

Limited experience with the use of ophthalmic dorzolamide indicate that it is unlikely to adversely affect the breastfed infant.[1] 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.
