Minocycline
"I've had acne since I was twelve and in 8th grade I developed moderate cystic acne which progressively got worse, so my doctor put me on minocycline and it totally cleared up my skin! I stopped getting cysts and I occasionally got one or two small white heads around the time of my period. I experienced minimal side effects, mostly nausea but it went away when I switched to taking the medication before bed. I've been off minocycline for about 6 months and since then been out on birth control, I noticed that the new meds break me out in cysts a lot more so I've started back on minocycline for the second time and my face is already clearer despite being on it for only a week! I love this stuff!"
