Doxycycline
"I started using this product when I was about 15 and used it for almost a year.  This medication made my skin extremely sensitive to sun. If I did not take this medication with food, I would feel like I was going to throw up.  Doxycycline was effective for controlling my acne, but the side effects did not make it a realistic choice.  
I have switched to using birth control pills for controlling my acne.  I have found that they are equally as effective as doxycycline, and I am no longer as prone to sunburns.  I also do not suffer from nausea from birth control.   
Overall, I have found birth control pills to be more compatible for my body, more useful (in their many purposes), and more convenient."
