I had horrible acne all throughout pregnancy which I refused to do anything but use natural remedies for. I have had my little one and am now breastfeeding. I still have horrible acne on my face, chest and back and I am looking to start treating it in a way that is safe while breastfeeding. My midwife told me the following medicines are considered safe. Does anyone have any experience with any of these? How did they work?

My options are- Adapalene (Differin), Azelaic acid (Azelex), Clindamycin (Cleocin), Erythromycin, Metronidazole (MetroGel) or Tretinoin (Retin-A, Topical)
