Doxycycline
"I was told by my doctor to take the doxycycline 100mg once a day for 3 months. So far it has been 3 weeks and I think my acne is getting worst. The first week my acne seemed to be improving. That was until the 2nd week it started getting worst. I'm starting to think it might be my period causing me to break out again. So I'm hoping I will see an improvement when its over. I have had no bad side effects which is great. After reading positive feedback on this I am really hoping to see a huge difference!! BE PATIENT"
