Summary of Use during Lactation

No information is available on the use of oral aminolevulinic acid during breastfeeding. To minimize exposure of the infant, breastfeeding can be withheld for 24 hours after an oral dose. Breastfeeding is not expected to result in exposure of the child to topical aminolevulinic acid due to negligible systemic absorption. Aminolevulinic acid-induced photodynamic therapy has been used successfully to treat various skin lesions of the nipple. This treatment appeared to preserve nipple anatomy for breastfeeding.[1-3]
