Is L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)-? Is L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- safe for nursing mother and child? Does L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- extracts into breast milk? Does L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- has any long term or short term side effects on infants? Can L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- influence milk supply or can L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- decrease milk supply in lactating mothers?

Breastmilk levels of L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- have not been measured in humans. Because absorption from the eye is limited, ophthalmic L-Phenylalanine, N-((2-(6-benzofuranylcarbonyl)-5,7-dichloro-1,2,3,4-tetrahydro-6-isoquinolinyl)carbonyl)-3-(methylsulfonyl)- would not be expected to cause any adverse effects in breastfed infants. 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.
