Minocycline
"This medication changed my life! I'm 22 and had had acne for about 4 years. I had tried everything from OTC to home remidies to topical gels from my general doctor, but nothing worked. I finally went to the derm and he prescribed 100mg  twice a day. That was too much for my body and I got severe nausea, headaches, anxiety. I opted to only take one 100mg pill every night and within three weeks I saw drastic changes! Now 3 months in I have no live breakouts just a couple scars!"
