Minocycline
"I have been dealing with nodular acne for years. I finally decided to go to dermatologist. She prescribed minocycline. In a week, I begin to see results. My skin was cleaning. Unfortunately by the second week, I started to break out in hives and was itching really bad. I called the doctor and explained what was happening. She told me to stop taking the medicine due to my allergic reaction to it."
