hi doctor, am breastfeeding my 7 month old and have a horrible breakout of cystic acne. am on amoxicillin.i always had acne from the age of 13 due to polycystic ovaries. Never been on isotroin. Have managed with antibiotics and topicals and birthcontrol pills. i know that isotroin shouldnt be taken during pregnancy as it causes birth defects. But what about during breastfeeding and that too, a very small dose?
