Hi. I have been taking 37.5mg of Phentermine the past 7 days and I am breastfeeding. I just now found out that this medication is a huge NO, NO while nursing. I will be stopping this drug immediatley! I am terrified something will happen to my baby. What can happen to her now that I have nursed her with this in my system as I know its definitely in my breast milk? How much of this was secreted in my breastmilk? I'm a FTM.
