Is Latisse Safe While Breastfeeding?

Latisse is composed of the basic ingredient Bimatoprost also known as Lumigan. Latisse is applied to the skin of the eyelid. Lumigan is also available as a glaucoma medication that is administered directly into the eye. It apparently undergoes minimal systemic absorption and the quantities that find its way into human breast milk is unknown. In animal studies, bimatoprost was excreted in breast milk.

To be on the safe side, I would recommend you stop using Latisse while breastfeeding. There is no research indicating the impact of the product on breastfeeding, but it's always better to be safe than sorry.
