Studies in animals are inadequate or may be lacking, but available data show no evidence of an increased occurrence of fetal damage.

Comments:
-To diminish systemic absorption, place pressure over the tear duct by the corner of the eye for 1 minute or more after using eye drops; remove excess solution with an absorbent tissue.

Oral bioavailability of this drug is about 40%; if it is excreted in human milk, it is unlikely to reach the infant in large amounts. Oral and IV administration may decrease milk production. If precautions are taken to limit systemic absorption, it is unlikely that ophthalmic use will affect milk production.
