I am being treated for thrush in my milk ducts with diflucan, and I have noticed that since I've started the treatment, my milk supply has slowly decreased. I EP, so I can see the change in the output. I used to get 4 oz total every three hours, and now I'm down to 3 oz total every three hours. Could this be a side effect of the medication? Has anyone else been through this? Will my supply come back? I really don't want to feed my baby formula, and at this rate, he would need a few ounces every day.
