It is funny how questions come in groups. At the moment many mothers are contacting me with questions about Rosacea particularly wanting to use Soolantra (Ivermectin cream).
This is the chapter from my book Breastfeeding and Chronic Medical Conditions which I hope helps. https://tinyurl.com/mbbebe8x
The information on ivermectin cream is limited but Hale suggests a relative infant dose of 1.3 even after oral medication, so topical absorption is unlikely to affect a breastfed infant.
