Is Resorcinolphthalein Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Resorcinolphthalein? Is Resorcinolphthalein safe for nursing mother and child? Does Resorcinolphthalein extracts into breast milk? Does Resorcinolphthalein has any long term or short term side effects on infants? Can Resorcinolphthalein influence milk supply or can Resorcinolphthalein decrease milk supply in lactating mothers?

It is used topically to depict local lesion in the eye. Also used intravenously as a dye for angiographic test procedures. It is a photo-sensitizing drug: avoid using it in mothers whose infants are on phototherapy. American Academy of Pediatrics: Maternal Medication Usually Compatible With Breastfeeding.

After intravenous use in a nursing mother, milk levels and the dose received by the infant are much higher. It is unlikely that these higher levels are problematic for most infants, but exposure to intense light, such as phototherapy, should probably be avoided for a few days after the maternal dose. Because absorption from the eye is limited, Resorcinolphthalein 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.
