Doxycycline
"I've had acne for about 3-4 years. Was prescribed doxy and can not get through a week of taking it! It's been 5 days and I haven't had a pimple at all where I was getting at least two a day BUT on the fifth day I have small bumps on my forehead and my forehead is always clear but that's not the issue. I had severe headaches every night, my head felt so tight! I also got a small rash on my arm (about the size of a coin) on the forth day. The next day I had about 2 more small rashes on my body. My chest and boobs are covered in little spots and some have a white head, same with my back and I never had issues with my back or chest before! Down stairs area is so dry and sore. Honestly can't stand the side effects. Not worth the pain!"
