Minocycline
"I had acne for 7 years. By senior year of high school, I couldn't take it anymore. I went to a dermatologist and he prescribed minocycline to me. I was afraid of the initial breakout, but it wasn't bad whatsoever! My acne cleared up sooooooo much. My skin was clear by the second week! It got rid of ALL of my blackheads. I took it for about 5  months. It's been 6 months since I stopped, and I still get small breakouts, but it's nothing like the acne I had before it. I love minocycline. While I was on it I looked prettier, my hair looked healthier, my skin wasn't oily, just everything about me felt and looked better. It gave me a yeast infection, but I ate yogurt...a LOT of yogurt, and that got rid of it right away."
