acne
"I've been on this medication for over 2 years, off and on. My derma said it could cause long term effects such a blue gums and teeth but I hadn't noticed that side effect until recently on my gums. The minocycline helped with my hormonal acne, but not my usual breakouts. I've struggled with acne for 10+ years so it's obviously frustrating but my derma has had me try everything to avoid the possibility of me going onto isotretenoin. Since I've noticed my gums turning blue, I decided to stop taking the minocycline. Ever since I stopped my skin has been looking clearer. I don't think this medication or antibiotic is meant for long term use at all."
