Eczema and hydrocortisone

Callie
I forgot to ask my doctor today. I've developed eczema pretty badly on my arms over the past two weeks and went to see my doctor about it today (didn't know what it was). She told me to use eczema lotion mixed with 1% hydrocortisone cream. Is the hydrocortisone safe to use while breastfeeding? And it won't effect my supply right? I already am dealing with low supply.
