Is Aminolevulinic acid hexyl ester Safe in Breastfeeding

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

No information is available on the clinical use of Aminolevulinic acid hexyl ester during breastfeeding. After instillation into the bladder, only about 7% of a dose is absorbed into the maternal bloodstream, so the amount of drug excreted into milk is expected to be minimal. If Aminolevulinic acid hexyl ester is required by the mother, it is not a reason to discontinue breastfeeding. Until more data become available, Aminolevulinic acid hexyl ester should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant.
