I have been on erythromycin for my skin for over a year. The consultant who prescribed them knew that i was TTC and said these were safe to take. I tried stopping them but my skin went awful. I am now nearly 20 weeks pregnant and I haev just telephoned my doctor for a repeat presciption and she has come back with "I shouldn't be taking them because I am pregnant".. has anyone else been on these? I am sooo worried.
