acne
"I'm a healthy 25 year old female who's been on minocycline for about 3-4 months now.  It's worked wonders and I didn't have any side effects to it, until now.  About two weeks ago, I had this awful abdominal pain that landed me in the ER for fear it was my appendix.  Everything came back perfect.  I've since cut back on my antibiotic and only take it every other day because through process of elimination, I think it's the culprit to my abdominal pain.  My PCP told my I may have developed acute IBS or irritable bowel syndrome from the minocycline (since it is an anti-biotic and will get rid of normal flora).  I'm very upset that I have to stop it; I rarely use any cover up now because my skin is so clear."
